1.3 Understanding Key Oracle Fusion Middleware Concepts

Oracle Fusion Middleware provides two types of components:

- A Java component, which is an Oracle Fusion Middleware component that is deployed as one or more Java EE applications and a set of resources. Java components are deployed to an Oracle WebLogic Server domain as part of a domain template. Examples of Java components are the Oracle SOA Suite and Oracle WebCenter components.

- A system component, which is a manageable process that is not deployed as a Java application. Instead, a system component is managed by Oracle Process Manager and Notification (OPMN). System components are:

- Oracle HTTP Server

- Oracle Web Cache

- Oracle Internet Directory

- Oracle Virtual Directory

- Oracle Forms Services

- Oracle Reports

- Oracle Business Intelligence Discoverer

- Oracle Business Intelligence

A Java component and a system component are peers.

After you install and configure Oracle Fusion Middleware, your Oracle Fusion Middleware environment contains the following:

- An Oracle WebLogic Server domain, which contains one Administration Server and one or more Managed Servers. The Administration Server contains Oracle WebLogic Server Administration Console and Oracle Enterprise Manager Fusion Middleware Control. The Managed Servers contain components, such as Oracle WebCenter and Oracle SOA Suite. See Section 1.3.1 for more information about domains.

- If your environment includes system components, one or more Oracle instances. See Section 1.3.2 for more information about Oracle instances.

- A metadata repository, if the components you installed require one. For example, Oracle SOA Suite requires a metadata repository. See Section 1.3.6 for more information about metadata repositories.

Figure 1-1 shows an Oracle Fusion Middleware environment with an Oracle WebLogic Server domain that contains an Administration Server, two Managed Servers, and an Oracle instance. The environment also includes a metadata repository.

Figure 1-1 Oracle Fusion Middleware Environment

Description of "Figure 1-1 Oracle Fusion Middleware Environment"

Your environment also includes a Middleware home, which consists of the Oracle WebLogic Server home, and optionally, an Oracle Common home and one or more Oracle homes. See Section 1.3.3 for more information about a Middleware home.

1.3.1 What Is an Oracle WebLogic Server Domain?

An Oracle WebLogic Server administration domain is a logically related group of Java components. A domain includes a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional WebLogic Server instances called Managed Servers. You deploy Java components, such as Web applications, EJBs, and Web services, and other resources, to the Managed Servers and use the Administration Server for configuration and management purposes only.

Managed Servers in a WebLogic Server domain can be grouped together into a cluster.

The directory structure of a domain is separate from the directory structure of the WebLogic Server home. It can reside anywhere; it need not be within the Middleware home directory. The top-level directory of a domain is referred to as the domain home.

An Oracle WebLogic Server domain is a peer of an Oracle instance. Both contain specific configurations outside of their Oracle homes.

Figure 1-2 shows an Oracle WebLogic Server domain with an Administration Server, three standalone Managed Servers, and three Managed Servers in a cluster.

Figure 1-2 Oracle WebLogic Server Domain

Description of "Figure 1-2 Oracle WebLogic Server Domain"

See Also:

Oracle Fusion Middleware Understanding Domain Configuration for Oracle WebLogic Server for more information about domain configuration

The following topics describe entities in the domain:

- What Is the Administration Server?

- What Are Managed Servers and Managed Server Clusters?

- What Is Node Manager?

1.3.1.1 What Is the Administration Server?

The Administration Server operates as the central control entity for the configuration of the entire WebLogic Server domain. It maintains the domain's configuration documents and distributes changes in the configuration documents to Managed Servers. The Administration Server serves as a central location from which to manage and monitor all resources in a domain.

Each Oracle WebLogic Server domain must have one server instance that acts as the Administration Server.

To interact with the Administration Server, you can use the Oracle WebLogic Server Administration Console, Oracle WebLogic Scripting Tool (WLST), or create your own JMX client. In addition, you can use Fusion Middleware Control for some tasks.

Fusion Middleware Control and the WebLogic Administration Console run in the Administration Server. Fusion Middleware Control is a Web-based administration console used to manage Oracle Fusion Middleware, including components such as Oracle HTTP Server, Oracle SOA Suite, Oracle WebCenter, Oracle Portal, and Oracle Identity Management components. Oracle WebLogic Server Administration Console is the Web-based administration console used to manage the resources in an Oracle WebLogic Server domain, including the Administration Server and Managed Servers.

See Also:

- Section 2.2 for more information about Fusion Middleware Control

- Section 2.3, as well as the Oracle Fusion Middleware Introduction to Oracle WebLogic Server and the Oracle WebLogic Server Administration Console Online help, for more information about Oracle WebLogic Server Administration Console

1.3.1.2 What Are Managed Servers and Managed Server Clusters?

Managed Servers host business applications, application components, Web services, and their associated resources. To optimize performance, Managed Servers maintain a read-only copy of the domain's configuration document. When a Managed Server starts, it connects to the domain's Administration Server to synchronize its configuration document with the document that the Administration Server maintains.

When you create a domain, you create it using a particular domain template. That template supports a particular component or group of components, such as Oracle SOA Suite. The Managed Servers in the domain are created specifically to host those particular Oracle Fusion Middleware components.

Oracle Fusion Middleware Java components (such as Oracle SOA Suite, Oracle WebCenter, and some Identity Management components), as well as customer-developed applications, are deployed to Managed Servers in the domain.

If you want to add other components, such as Oracle WebCenter, to a domain that was created using a template that supports another component, you can extend the domain by creating additional Managed Servers in the domain, using a domain template for the component which you want to add. See Section 9.2 for more information.

For production environments that require increased application performance, throughput, or high availability, you can configure two or more Managed Servers to operate as a cluster. A cluster is a collection of multiple WebLogic Server instances running simultaneously and working together to provide increased scalability and reliability. In a cluster, most resources and services are deployed identically to each Managed Server (as opposed to a single Managed Server), enabling failover and load balancing. A single domain can contain multiple WebLogic Server clusters, as well as multiple Managed Servers that are not configured as clusters. The key difference between clustered and non-clustered Managed Servers is support for failover and load balancing. These features are available only in a cluster of Managed Servers.

1.3.1.3 What Is Node Manager?

Node Manager is a Java utility that runs as a separate process from Oracle WebLogic Server and allows you to perform common operations for a Managed Server, regardless of its location with respect to its Administration Server. While use of Node Manager is optional, it provides valuable benefits if your Oracle WebLogic Server environment hosts applications with high-availability requirements.

If you run Node Manager on a computer that hosts Managed Servers, you can start and stop the Managed Servers remotely using the Administration Console or the command line. Node Manager can also automatically restart a Managed Server after an unexpected failure.

See Also:

Oracle Fusion Middleware Node Manager Administrator's Guide for Oracle WebLogic Server

1.3.2 What Is an Oracle Instance?

An Oracle instance contains one or more system components, such as Oracle Web Cache, Oracle HTTP Server, or Oracle Internet Directory. The system components in an Oracle instance must reside on the same computer. An Oracle instance directory contains updatable files, such as configuration files, log files, and temporary files.

An Oracle instance is a peer of an Oracle WebLogic Server domain. Both contain specific configurations outside of their Oracle homes. However, unlike a domain, which can span multiple hosts, an Oracle instance must be located on a single host.

The directory structure of an Oracle instance is separate from the directory structure of the Oracle home. It can reside anywhere; it need not be within the Middleware home directory.

1.3.3 What Is a Middleware Home?

A Middleware home consists of the Oracle WebLogic Server home, and, optionally, one Oracle Common home and one or more Oracle homes.

A Middleware home can reside on a local file system or on a remote shared disk that is accessible through NFS.

See Section 1.3.4 for information about WebLogic Server home. See Section 1.3.5 for information about Oracle home.

1.3.4 What Is a WebLogic Server Home?

A WebLogic Server home contains installed files necessary to host a WebLogic Server. The WebLogic Server home directory is a peer of Oracle home directories and resides within the directory structure of the Middleware home.

1.3.5 What Is an Oracle Home and the Oracle Common Home?

An Oracle home contains installed files necessary to host a specific component or software suite. For example, the SOA Oracle home contains a directory that contains binary and library files for Oracle SOA Suite.

An Oracle home resides within the directory structure of the Middleware home. Each Oracle home can be associated with multiple Oracle instances or Oracle WebLogic Server domains. There can be multiple Oracle homes within each Middleware home.

The Oracle Common home contains the binary and library files required for Fusion Middleware Control and Java Required Files (JRF). There can be only one Oracle Common home within each Middleware home.

1.3.6 What Is the Oracle Metadata Repository?

The Oracle Metadata Repository contains metadata for Oracle Fusion Middleware components, such as Oracle BPEL Process Manager, Oracle B2B, and Oracle Portal. It can also contain metadata about the configuration of Oracle Fusion Middleware and metadata for your applications.

A metadata repository can be database-based or file-based. If it is database-based, you can create it in an existing database using the Repository Creation Utility (RCU).

Oracle Fusion Middleware supports multiple repository types. A repository type represents a specific schema or set of schemas that belong to a specific Oracle Fusion Middleware component (for example, Oracle SOA Suite or Oracle Internet Directory.)

A particular type of repository, the Oracle Metadata Services (MDS) repository, contains metadata for most Oracle Fusion Middleware components, such as Oracle B2B, and for certain types of applications.

See:

- Section 3.2.1 for information about creating a metadata repository

- "Managing the Metadata Repository Schemas" in the Oracle Fusion Middleware Administrator's Guide for information about managing a metadata repository

1.4 Common Administration Tasks

As an administrator for Oracle Fusion Middleware, you can expect to be involved in the following tasks:

- Installing Oracle Fusion Middleware software

- Performing the initial configuration of the software

- Configuring a metadata repository

- Deploying applications

- Managing administrative accounts

- Monitoring the environment

- Backing up and recovering your Oracle Fusion Middleware environment

1.5 Tools for Administering Oracle Fusion Middleware

The following are some of the tools and utilities that you can use in administering Oracle Fusion Middleware:

- Oracle Enterprise Manager Fusion Middleware Control
Fusion Middleware Control is a Web-based interface and is one of the primary tools for managing your Oracle Fusion Middleware environment. With it, you can check the status of the components, start and stop components, deploy Java EE applications, and perform other administrative tasks, such as creating clusters and managing log files. See Section 2.2.

- Oracle WebLogic Server Administration Console
The Oracle WebLogic Server Administration Console is a Web browser-based, graphical user interface that you use to manage an Oracle WebLogic Server domain. See Section 2.3.

- WebLogic Scripting Tool (WLST)
The WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to create, manage, and monitor Oracle WebLogic Server domains. See Section 2.4.1.

- Oracle Process Manager and Notification Server (OPMN)
Oracle Process Manager and Notification Server (OPMN) manages and monitors a particular type of Oracle Fusion Middleware components, referred to as system components. See Section 2.4.2.

- Oracle Fusion Middleware Metadata Repository Creation Utility
The Repository Creation Utility (RCU) creates a metadata repository in an existing database. You can use it to create a repository for overall configuration information and for configuration information for particular components. Not all Oracle Fusion Middleware components need a database-based metadata repository, but some, like the Oracle SOA Suite, do. See Section 3.2.1 for more information about RCU.

- System MBean browser
An MBean is a Java object that represents a JMX manageable resource. Each manageable resource within the application server, such as an application or a resource adapter, is managed through an instance of the appropriate MBean. Each MBean exposes a management interface that is accessible through the System MBean Browser in Fusion Middleware Control. You can set MBean attributes, execute operations to call methods on an MBean, subscribe to notifications of errors or specific events, and display execution statistics.

For more information, see the section "Using the Fusion Middleware Control MBean Browser" in the Oracle Fusion Middleware Administrator's Guide.

2 Getting Started with Management Tools

When you install Oracle Fusion Middleware, you install the binary files, such as executable files, jar files, and libraries. Then, you use configuration tools to configure the software. This chapter provides information you need to get started managing Oracle Fusion Middleware, including information about the tools you use.

This chapter includes the following topics:

2.1 Overview of Oracle Fusion Middleware Management Tools

After you install and configure Oracle Fusion Middleware, you can use the graphical user interfaces or the command-line tools to manage your environment.

Oracle offers the following primary tools for managing your Oracle Fusion Middleware installations:

- Oracle Enterprise Manager Fusion Middleware Control. See Section 2.2.

- Oracle WebLogic Server Administration Console. See Section 2.3.

- The Oracle Fusion Middleware command-line tools. See Section 2.4.

In addition, you can use the Fusion Middleware Control MBean Browser, which is described in the section "Using the Fusion Middleware Control MBean Browser" in the Oracle Fusion Middleware Administrator's Guide.

Note that you should use these tools, rather than editing configuration files, to perform all administrative tasks unless a specific procedure requires you to edit a file. Editing a file may cause the settings to be inconsistent and generate problems.

Note:

For information about using administration tools for IBM WebSphere, see "Summary of the Oracle Fusion Middleware Management Tools on IBM WebSphere" in the Oracle Fusion Middleware Third-Party Application Server Guide.

Both Fusion Middleware Control and Oracle WebLogic Server Administration Console are graphical user interfaces that you can use to monitor and administer your Oracle Fusion Middleware environment. You can perform some tasks with either tool, but, for other tasks, you can only use one of the tools. Table 2-1 lists some common tasks and the recommended tool.

2.2 Getting Started with Oracle Enterprise Manager Fusion Middleware Control

Fusion Middleware Control is a Web-based interface from which you can monitor and administer a farm.

A farm is a collection of components managed by Fusion Middleware Control. It can contain an Oracle WebLogic Server domain, one Administration Server, one or more Managed Servers, clusters, one or more Oracle instances, and the Oracle Fusion Middleware components that are installed, configured, and running in the domain or Oracle instances.

Fusion Middleware Control organizes a wide variety of performance data and administrative functions into distinct, Web-based home pages for the farm, domain, servers, components, and applications. The Fusion Middleware Control home pages make it easy to locate the most important monitoring data and the most commonly used administrative functions—all from your Web browser.

The following topics are discussed in this section:

- Displaying Fusion Middleware Control

- Navigating Within Fusion Middleware Control

- Using Fusion Middleware Control Help

2.2.1 Displaying Fusion Middleware Control

To display Fusion Middleware Control, you enter the Fusion Middleware Control URL, which includes the name of the host and the port number assigned during the installation. The following shows the format of the URL:

http://hostname.domain:port/em

The port number is the port number of the Administration Server. By default, the port number is 7001.

For some installation types, such as SOA or Web Tier, if you saved the installation information by clicking Save on the last installation screen, the URL for Fusion Middleware Control is included in the file that is written to disk (by default to your home directory).

For other installation types, the information is displayed on the Create Domain screen of the Configuration Wizard when the configuration completes.

To display Fusion Middleware Control:

1. Enter the Fusion Middleware Control URL in your Web browser. For example:

http://host1.example.com:7001/em

The following shows the login page:

Description of the illustration welcome.gif

2. Enter the Oracle Fusion Middleware administrator user name and password and click Login.
The default user name for the administrator user is weblogic. This is the account you can use to log in to Fusion Middleware Control for the first time. The password is the one you supplied during the installation of Oracle Fusion Middleware.

3. The Farm page is displayed, as shown in the following figure:

Description of the illustration farmhome.gif

The Farm menu is displayed at the top of the page. From the Farm menu, you can:

- Create and delete components and clusters

- View log messages

- Specify monitoring credentials

The Farm menu is always displayed, even if you have selected other targets.

You can view the topology of the domain by selecting Topology. The Topology Viewer provides you with a high-level view of the topology, including Managed Servers, deployed applications, and the routing configuration. For more information about viewing the topology, see Section 5.4.

2.2.2 Navigating Within Fusion Middleware Control

Fusion Middleware Control displays the target navigation pane on the left and the content pane to the right. For example, when you first log in to Fusion Middleware Control, the farm home page is displayed on the right.

From the target navigation pane, you can expand the tree and select an Oracle WebLogic Server domain, an Oracle WebLogic Server Managed Server, a component, an application, or a Metadata Repository.

When you select a target, such as a Managed Server or a component, the target's home page is displayed in the content pane and that target's menu is displayed at the top of the page, in the context pane. For example, if you select a Managed Server, the WebLogic Server menu is displayed. You can also view the menu for a target by right-clicking the target in the navigation pane.

The following figure shows the target navigation pane and the home page of a Managed Server. Because a Managed Server was selected, the dynamic target menu listed in the context pane is the WebLogic Server menu.

Description of the illustration nav.gif

In the preceding figure, the following items are called out:

- Target Navigation Pane lists all of the targets in the farm in a navigation tree.

- Content Pane shows the current page for the target. When you first select a target, that target's home page is displayed.

- Farm Menu provides a list of operations that you can perform on the farm. The Farm menu is always available.

- Dynamic Target Menu provides a list of operations that you can perform on the currently selected target. The menu that is displayed depends on the target you select. The menu for a specific target contains the same operations as those in the Right-Click Target Menu.

- Right-Click Target Menu provides a list of operations that you can perform on the currently selected target. The menu is displayed when you right-click the target name in the target navigation pane. In the figure, even though the WebLogic Server is selected and its home page is displayed, the right-click target menu displays the operations for a metadata repository because the user has right-clicked the metadata repository.
The menu for a specific target contains the same operations as those in the Dynamic Target Menu.

- Topology Viewer displays the topology of the farm.

- Target Name is the name of the currently selected target.

- Target Information Icon provides information about the target. For example, for a domain, it displays the target name, the version, and the domain home.

- Context Pane provides the name of the target, the name of the current user, the host name, and the time of the last page refresh, as well as the Refresh icon.

- Expand All/Collapse All lets you expand or collapse the navigation tree.

- Refresh indicates when the page is being refreshed. Click it to refresh a page with new data. (Refreshing the browser window refreshes the page but does not retrieve new data.)

- Return to login takes you to the login page when you click the Oracle Enterprise Manager logo.

In addition, from Fusion Middleware Control, from the home pages of targets such as the Administration Server or Managed Servers, you can access the WebLogic Server Administration Console. For information about configuring Single Sign-On between Fusion Middleware Control and the WebLogic Server Administration Console, see "Configuring Single Sign-On for Administration Consoles" in the Oracle Fusion Middleware Enterprise Deployment Guide for Oracle Identity Management.

Table 2-2 describes some common ways you can navigate within Fusion Middleware Control.

2.2.3 Using Fusion Middleware Control Help

At any time while using the Fusion Middleware Control Console, you can click Help at the top of the page to get more information. In most cases, the Help window displays a help topic about the current page. Click Contents in the Help window to browse the list of help topics, or click Search to search for a particular word or phrase.

2.3 Getting Started with Oracle WebLogic Server Administration Console

Oracle WebLogic Server Administration Console is a Web browser-based, graphical user interface that you use to manage a WebLogic Server domain. It is accessible from any supported Web browser with network access to the Administration Server.

Use the Administration Console to:

- Configure, start, and stop Oracle WebLogic Server Managed Servers

- Configure Oracle WebLogic Server clusters

- Configure Oracle WebLogic Server services, such as database connectivity (JDBC) and messaging (JMS)

- Configure security parameters, including managing users, groups, and roles

- Configure and deploy Java EE applications

- Monitor server and application performance

- View server and domain log files

- View application deployment descriptors

- Edit selected run-time application deployment descriptor elements

2.3.1 Displaying the Administration Console

To display the Administration Console:

1. Enter the following URL in a browser:

http://hostname:port_number/console

The port number is the port number of the Administration Server. By default, the port number is 7001.

The login page is displayed.

2. Log in using the user name and password supplied during installation.
Oracle WebLogic Server Administration Console is displayed, as shown in the following figure:

Description of the illustration wls_admin.gif

Alternatively, you can access the Administration Console from Fusion Middleware Control, from the home pages of targets such as the Administration Server and Managed Server.

2.3.2 Locking the WebLogic Server Configuration

Before you make configuration changes, lock the domain configuration, so you can make changes to the configuration while preventing other accounts from making changes during your edit session.

To lock the domain configuration:

1. Locate the Change Center in the upper left of the Administration Console screen.

2. Click Lock & Edit to lock the configuration edit hierarchy for the domain.

As you make configuration changes using the Administration Console, you click Save (or in some cases Finish) on the appropriate pages. This does not cause the changes to take effect immediately. The changes take effect when you click Activate Changes in the Change Center. At that point, the configuration changes are distributed to each of the servers in the domain. If the changes are acceptable to each of the servers, then they take effect. If any server cannot accept a change, then all of the changes are rolled back from all of the servers in the domain. The changes are left in a pending state; you can then either edit the pending changes to resolve the problem or revert the pending changes.

2.4 Getting Started with the Oracle Fusion Middleware Command-Line Tools

The following topics describe the primary command-line tools you can use to manage most Oracle Fusion Middleware components:

- Getting Started Using the WebLogic Scripting Tool (WLST)

- Getting Started Using Oracle Process Manager and Notification Server

2.4.1 Getting Started Using the WebLogic Scripting Tool (WLST)

The WebLogic Scripting Tool (WLST) is a command-line scripting environment that you can use to create, manage, and monitor Oracle WebLogic Server domains. It is based on the Java scripting interpreter, Jython. In addition to supporting standard Jython features such as local variables, conditional variables, and flow-control statements, WLST provides a set of scripting functions (commands) that are specific to Oracle WebLogic Server. You can extend the WebLogic scripting language to suit your needs by following the Jython language syntax.

You can use any of the following techniques to invoke WLST commands:

- Interactively, on the command line

- In script mode, supplied in a file

- Embedded in Java code

For example, to invoke WLST interactively, and connect to the Oracle WebLogic Server, use the following commands:

java weblogic.WLST
connect('weblogic', 'weblogic', 'localhost:7001')

To display information about WLST commands and variables, enter the help command. For example, to display a list of categories for online commands, enter the following:

wls:/base_domain/serverConfig>  help('online')
help('activate')            Activate the changes.
help('addListener')         Add a JMX listener to the specified MBean.
help('adminHome')           Administration MBeanHome.
help('cancelEdit')          Cancel an edit session.
help('cd')                  Navigate the hierarchy of beans.
help('cmo')                 Current Management Object.
.
.
.

To monitor the status, you use the WLST state command, using the following format:

state(name, type)

For example, to view the status of the Managed Server soa_server1, use the following command:

wls:/SOA_domain/serverConfig> state('soa_server1', 'Server')
Current state of 'soa_server1' : RUNNING

See Also:

Oracle Fusion Middleware WebLogic Scripting Tool Command Reference

2.4.1.1 Using Custom WLST Commands

Many components, such as Oracle SOA Suite, Oracle Platform Security Services (OPSS), Oracle Fusion Middleware Audit Framework, and Oracle Metadata Service (MDS), and services such as SSL and logging, provide custom WLST commands.

To use those custom commands, you must invoke the WLST script from the appropriate Oracle home. Do not use the WLST script in the WebLogic Server home.

- For the following components and services, invoke WLST from the Oracle Common home:

- Oracle Application Development Framework

- Oracle Fusion Middleware Audit Framework

- Oracle Access Manager

- Oracle Platform Security Services

- Oracle Metadata Service

- Diagnostic Framework

- Dynamic Monitoring Service (DMS)

- Logging

- Secure Sockets Layer (SSL)

- Oracle Web Services

- Oracle Web Services Manager

The script is located at:

(UNIX) ORACLE_COMMON_HOME/common/bin/wlst.sh
(Windows) ORACLE_COMMON_HOME\common\bin\wlst.cmd

- For other components, such as Oracle HTTP Server, Oracle SOA Suite, or Oracle WebCenter, invoke WLST from the Oracle home in which the component has been installed. The script is located at:

(UNIX) ORACLE_HOME_for_component/common/bin/wlst.sh
(Windows) ORACLE_HOME_for_component\common\bin\wlst.cmd

For example, to run the custom WLST commands for Oracle SOA Suite on a Linux system, use the following commands:

cd ORACLE_HOME_for_SOA/common/bin
./wlst.sh

2.4.1.2 Using WLST Commands for System Components

In addition to the commands provided by WLST for Oracle WebLogic Server, WLST provides a subset of commands to manage system components. These commands are:

- startproc(componentName [, componentType] [, componentSet]): Starts the specified component.

- stopproc(componentName [, componentType] [, componentSet]): Stops the specified component.

- status(componentName [, componentType] [, componentSet]): Obtains the status of the specified component.

- proclist(): Obtains the list of components.

To use these custom commands, you must invoke the WLST script from the Oracle home in which the component has been installed. Do not use the WLST script in the WebLogic Server home. The script is located at:

(UNIX) ORACLE_HOME_for_component/common/bin/wlst.sh
(Windows) ORACLE_HOME_for_component\common\bin\wlst.cmd

2.4.2 Getting Started Using Oracle Process Manager and Notification Server

Oracle Process Manager and Notification Server (OPMN) manages and monitors the following Oracle Fusion Middleware components, referred to as system components:

- Oracle HTTP Server

- Oracle Web Cache

- Oracle Internet Directory

- Oracle Virtual Directory

- Oracle Forms Services

- Oracle Reports

- Oracle Business Intelligence Discoverer

- Oracle Business Intelligence

OPMN provides the opmnctl command. The executable file is located in the following directory, which you should add to your PATH environment variable:

(UNIX) ORACLE_INSTANCE/bin
(Windows)ORACLE_INSTANCE\bin

To view the status of all system components in an Oracle instance, use the following command:

opmnctl status
Processes in Instance: webtier_inst
---------------------------------+--------------------+---------+---------
ias-component                    | process-type       |     pid | status
---------------------------------+--------------------+---------+---------
webcache1                        | WebCache-admin     |   19556 | Alive
webcache1                        | WebCache           |   19555 | Alive
ohs1                             | OHS                |    7249 | Alive

To view the status of a particular component or component type, use the following command:

opmnctl status componentName [, componentType] [, componentSet]

For example, to view the status of an Oracle Virtual Directory instance named ovd1, use the following command:

opmnctl status ias-component=ovd1

You can use OPMN to start and stop system components, monitor system components, and perform many other tasks related to process management. For example, you can use the following commands to start and stop OPMN and all OPMN-managed processes, such as Oracle HTTP Server:

opmnctl startall
opmnctl stopall

Figure 3-1 Oracle WebLogic Server Domain with Administration Server and Managed Servers

Description of "Figure 3-1 Oracle WebLogic Server Domain with Administration Server and Managed Servers "

3.2 Installing and Configuring Oracle Fusion Middleware

The following are the general steps you need to take to install and configure Oracle Fusion Middleware:

1. Many components, such as Oracle SOA Suite, require a database-based metadata repository. If you are installing these components, you must have an existing database. Then, you use RCU to create a repository in the database. Section 3.2.1 provides information about using RCU.
For some installation types and components, you can use a file-based repository to store product metadata. The file-based repository is created during installation.

2. Install Oracle WebLogic Server. See Section 3.2.2.

3. Install other Oracle Fusion Middleware products. See Section 3.2.3.

4. Configure Oracle WebLogic Server and other Oracle Fusion Middleware products. See Section 3.2.4.

3.2.1 Creating the Schemas in a Database

Most components require a database-based repository. In those cases, you must use the Oracle Fusion Middleware Metadata Repository Creation Utility (RCU) to create the metadata repository in an existing database. You use RCU to create schemas to hold configuration information for particular components, and optionally, for overall configuration information.

In addition, you can use RCU to create a particular type of repository, the MDS Repository, which contains metadata for certain types of deployed applications. Those applications include custom Java applications developed by your organization and some Oracle Fusion Middleware Java components, such as Oracle B2B.

The following components do not require a database-based repository. They can store their configuration information in a file-based repository:

- Oracle HTTP Server

- Oracle Web Cache

- Oracle Web Services Manager

See:

- The appendix "Metadata Repository Schemas" in the Oracle Fusion Middleware Administrator's Guide for a list of schemas created for each component

- Oracle Fusion Middleware Repository Creation Utility User's Guide for information about using RCU

- For information about which versions of Oracle databases are supported, and other prerequisites, see:

http://www.oracle.com/technology/software/products/ias/files/fusion_certification.html

The procedure in this section assumes that you have an existing Oracle Database and that you have installed RCU.

Note:

Oracle recommends that all metadata repositories reside on a database at the same site as the components to minimize network latency issues.

To create schemas in a database:

1. Invoke RCU, using the following command:

(UNIX) RCU_HOME/bin/rcu
(Windows) RCU_hOME\bin\rcu.bat

2. On the Welcome page, click Next.
The Create Repository page appears.

3. To create the repository, which loads the component schemas into the database, select Create, then click Next.
The Database Connection Details page appears.

4. Provide the following information about the database into which you want to load the component schemas:

- Database Type: Select the type of database. This example assumes that you are using an Oracle Database.

- Host Name: Enter the host name for the computer where the database is installed, for example: myhost.example.com.

- Port: Enter the port number, for example: 1521.

- Service Name: Enter the Service Identifier (SID) for the database.

- Username: Enter a user name for the database which is assigned the SYSDBA role, for example: SYS.

- Password: Enter the password for the user.

- Role: Select SYSDBA.

5. Click Next.
The Checking Prerequisites dialog box is displayed.

6. When the operation completes, click OK.
The Select Components page appears.

7. On this page:

- Select Create a New Prefix, and enter characters to be added to the beginning of the schema names. For example, if you enter OFM, the Oracle Business Activity Monitoring schemas are named OFM_ORABAM.

- In the component table, select the components. For example, if you want to install Oracle SOA Suite components, select SOA and BPM Infrastructure, as shown in the following figure:
Description of the illustration rcu_comp.gif

8. Click Next.

9. The Checking Prerequisites dialog box is displayed. When the operation completes, click OK.
The Schema Passwords page appears.

10. You can use the same password for all schemas, or enter passwords for each schema. If you enter passwords for each schema, you can specify that auxiliary schemas use the same password as the main schema. In this case, select Use same passwords for all schemas. Then, enter the password and re-enter it to confirm.

11. Click Next.
The Custom Variables page appears if you selected the Oracle Data Integrator schema on the Select Components page.

12. If the Custom Variables page appears, enter values for the passwords.

13. Click Next.
The Map Tablespaces page appears.

14. This page displays the default tablespaces for each schema. You can manage the tablespaces, configuring the size, storage type, and data files for the tablespaces. In addition, depending on the components you selected, you may be able to specify additional tablespaces for the components.
For this example, assume the default tablespace is adequate. Click Next.

15. A dialog box is displayed that says that any tablespaces that do not already exist are created. Click OK.

16. A progress box is displayed. When the operation completes, click OK.
The Summary page appears.

17. Review the information and click Create.
A progress dialog box is displayed.

18. When it completes, note the details in the Completion Summary, and click Close.

Now, you have created a database-based metadata repository and have populated it with the required schemas.

3.2.2 Installing Oracle WebLogic Server

You use the Oracle WebLogic Server installation program to install Oracle WebLogic Server. For the scenarios in this book, accept the default values in the installer, creating a new Middleware home.

When the installation completes, you have a Middleware home and a WebLogic Server home. By default, the Middleware home is:

(UNIX) user_home/Oracle/Middleware
(Windows) user_home\Oracle\Middleware

See Also:

Oracle Fusion Middleware Installation Guide for Oracle WebLogic Server for more information.

3.2.3 Installing Additional Oracle Fusion Middleware Components

You use the installer to install, and, in some cases, to optionally configure Oracle Fusion Middleware.

For the procedures in this book, use the Oracle SOA Suite install type. Refer to the Oracle Fusion Middleware Installation Guide for Oracle SOA Suite and Oracle Business Process Management Suite. To make it easier to complete the procedures in this book, note the following on the Specify Installation Location page:

- For Oracle Middleware Home, specify the Middleware home directory that was created when you installed Oracle WebLogic Server. For example, if your Middleware home is /scratch/oracle/Oracle/Middleware, then specify the following:

/scratch/oracle/Oracle/Middleware

- For Oracle Home Directory, specify a name for the Oracle home. For example:

Oracle_SOA1

The Oracle Home is created as a subdirectory of the Middleware home.

3.2.4 Configuring Oracle Fusion Middleware Components

You can configure some components, such as Oracle HTTP Server or Oracle Web Cache, when you install them. For other components, such as Oracle WebLogic Server, Oracle SOA Suite, or Oracle WebCenter, you must configure the components using the Oracle Fusion Middleware Configuration Wizard.

To configure Oracle WebLogic Server and Oracle SOA Suite:

1. Invoke the Configuration Wizard, which is located in the following directory:

(UNIX) ORACLE_HOME_for_component/common/bin/config.sh
(Windows) ORACLE_HOME_for_component\common\bin\config.cmd

2. Follow the directions in the Installation Guide for the components. For example, for Oracle SOA Suite, follow the directions in the section "Configuration Instructions" in the Oracle Fusion Middleware Installation Guide for Oracle SOA Suite and Oracle Business Process Management Suite.
Note the following:

- In the Welcome screen, select Create a new WebLogic domain.

- In the Select Domain Source screen, select Oracle SOA Suite, Oracle Enterprise Manager, and Oracle Business Activity Monitoring. This automatically also selects Oracle JRF, and Oracle WSM Policy Manager.

- In the Specify Domain Name screen, specify SOA_domain for the name of the domain and take the default for the domain location, as shown in the following figure:
Description of the illustration config_wiz.gif

- In the Configure Administrator User Name and Password screen, use the default user name, weblogic, and enter a password. Then, re-enter the password.

- In the Configure Server Start Mode and JDK screen, select Production Mode.

- In the Configure JDBC Component Schema screen, the following instructions assume that you have the same password and database for all of the schemas:

- Select all of the schemas.

- For Vendor, select Oracle.

- For Driver, select Oracle's Driver (Thin) for Service connections; Versions:9.0.1,9.2.0,10,11.

- For Schema Owner, do not enter anything if the schemas listed in the table are correct. Each data source uses the user name specified in the table.
If you need to change the schema owner, select each schema individually, then change the owner name.

- If you used the same password for all schemas when you created the schemas, enter the password in Schema Password.
Alternatively, you can specify different passwords for each data source by entering them in the password column of the table.

- With all of the schemas selected, for DBMS/Service, enter the SID of the database.

- With all of the schemas selected, for Host Name, enter the host name of the database.

- With all of the schemas selected, for Port, enter the listening port of the database.

The following figure shows the Configure JDBC Component Schema page:

Description of the illustration config_wiz2.gif

- Click Next.
The Test JDBC Component Schema screen is displayed. If the test is successful, click Next. If the test is not successful, click Previous and correct the information.

- In the Select Optional Configuration screen, take the defaults. Click Next.
The Configuration Summary screen is displayed.

- Click Create.

- When the operation has completed, note the Admin Server URL in the Creating Domain screen. For example:

Admin Server URL: http://hostname.domainname.com:7001

Now, you have created a domain, including an Administration Server and two Managed Servers, soa_server1 and bam_server1.

3. Start the Administration Server. For example, on Linux, if your domain is SOA_domain, run the following script (MW_HOME is the Middleware home):

MW_HOME/user_projects/domains/SOA_domain/bin/startWeblogic.sh

Provide the user name and password when prompted.

4. Start the Managed Servers. For example, on Linux, if your server is named soa_server1, run the following script, entering the user name and password when prompted:

MW_HOME/user_projects/domains/SOA_domain/bin/startManagedWebLogic.sh
soa_server1 http://hostname:7001

5. When your environment contains Oracle Fusion Middleware products other than Oracle WebLogic Server, such as Oracle SOA Suite, Oracle WebCenter, or Oracle JRF, you must configure Node Manager to enable starting and stopping Managed Servers using Fusion Middleware Control. See Section 3.4.3.

When the configuration completes and you have started the Administration Server and the Managed Servers, you can view and manage Oracle Fusion Middleware using the graphical user interfaces or command-line tools. For example, to use Fusion Middleware Control to view and managed your environment, enter the Admin Server URL you noted from the Creating Domain screen, with /em appended. For example:

http://hostname.domainname:port/em

By default, the port is 7001.

Note:

You can extend a domain to include the templates for other components by using the Configuration Wizard. For example, you can extend a domain that was initially created to support Oracle SOA Suite so that it can now also support Oracle WebCenter or Oracle HTTP Server. For more information, see Section 9.2.

For information about using the tools to view and manage Oracle Fusion Middleware, see:

- For graphical user interfaces: Section 2.2 and Section 2.3.

- For command-line tools: Section 2.4.

For more information about configuring components, see the Installation Guide for that component.

3.3 Setting Up Environment Variables

When you installed Oracle Fusion Middleware, you were logged in to your operating system as a particular user. You should always log in as this user to manage your installation because this user has permission to view and modify the files in your installation's Oracle home.

To use Oracle Fusion Middleware, you must set environment variables as shown in the following tables:

- Table 3-1, "Environment Variables for Linux and UNIX"

- Table 3-2, "Environment Variables for Windows"

Table 3-1 Environment Variables for Linux and UNIX

3.4 Starting and Stopping Servers, Components, and Applications

You can start and stop servers, components, and applications using the command line, the Oracle WebLogic Server Administration Console, or Fusion Middleware Control. The following topics describe how to start and stop these entities using Fusion Middleware Control, the command line, or both:

- Starting and Stopping Oracle WebLogic Server Administration Server

- Starting and Stopping Oracle WebLogic Server Managed Servers

- Configuring Node Manager to Start Managed Servers

- Starting and Stopping Components

- Starting and Stopping Applications

- Starting and Stopping Fusion Middleware Control

- Starting and Stopping Oracle Management Agent

3.4.1 Starting and Stopping Oracle WebLogic Server Administration Server

You can start and stop Oracle WebLogic Server Administration Servers using the WLST command line or scripts. When you start or stop the Administration Server, you also start or stop the processes running in the Administration Server, including the WebLogic Server Administration Console and Fusion Middleware Control.

To start an Oracle WebLogic Server Administration Server, use the following script:

MW_HOME/user_projects/domains/domain_name/bin/startWebLogic.sh
-Dweblogic.management.username=weblogic
-Dweblogic.management.password=password
-Dweblogic.system.StoreBootIdentity=true

To stop an Oracle WebLogic Server Administration Server, use the following script:

MW_HOME/user_projects/domains/domain_name/bin/stopWeblogic.sh
username password [admin_url]

3.4.2 Starting and Stopping Oracle WebLogic Server Managed Servers

Fusion Middleware Control and the Oracle WebLogic Server Administration Console use Node Manager to start Managed Servers. If you are starting a Managed Server that does not contain Oracle Fusion Middleware products other than Oracle WebLogic Server, you can start the servers using the procedure in this section.

However, if the Managed Server contains other Oracle Fusion Middleware products, such as Oracle SOA Suite, Oracle WebCenter, or Oracle JRF, you must first configure Node Manager, as described in Section 3.4.3.

See Also:

Oracle Fusion Middleware Oracle WebLogic Scripting Tool

To start or stop a Managed Server using Fusion Middleware Control:

1. From the navigation pane, expand the farm, then WebLogic Domain, and then the domain.

2. Select the Managed Server.

3. From the WebLogic Server menu, select Control, then Start Up or Shut Down.

WLST Scripts:

To start a Managed Server:

MW_HOME/user_projects/domains/domain_name/bin/startManagedWebLogic.sh
server_name admin_url username password

To stop a Managed Server:

MW_HOME/user_projects/domains/domain_name/bin/stopManagedWeblogic.sh
username password admin_url

3.4.3 Configuring Node Manager to Start Managed Servers

If a Managed Server contains other Oracle Fusion Middleware products, such as Oracle SOA Suite, Oracle WebCenter, or Oracle JRF, the Managed Servers environment must be configured to set the correct classpath and parameters. This environment information is provided through the start scripts, such as startWebLogic and setDomainEnv, which are located in the domain directory.

If the Managed Servers are started by Node Manager (as is the case when the servers are started by the Oracle WebLogic Server Administration Console or Fusion Middleware Control), Node Manager must be instructed to use these start scripts so that the server environments are correctly configured. Specifically, Node Manager must be started with the property StartScriptEnabled=true.

There are several ways to ensure that Node Manager starts with this property enabled. As a convenience, Oracle Fusion Middleware provides the following script, which adds the property StartScriptEnabled=true to the nodemanager.properties file:

(UNIX) ORACLE_COMMON_HOME/common/bin/setNMProps.sh.
(Windows) ORACLE_COMMON_HOME\common\bin\setNMProps.cmd

For example, on Linux, execute the setNMProps script and start Node Manager:

ORACLE_COMMON_HOME/common/bin/setNMProps.sh
MW_HOME/wlserver_n/server/bin/startNodeManager.sh

When you start Node Manager, it reads the nodemanager.properties file with the StartScriptEnabled=true property, and uses the start scripts when it subsequently starts Managed Servers. Note that you need to run the setNMProps script only once.

See Also:

"Using Node Manager" in the Oracle Fusion Middleware Node Manager Administrator's Guide for Oracle WebLogic Server for other methods of configuring and starting Node Manager

3.4.4 Starting and Stopping Components

You can start and stop a component from the dynamic target menu in Fusion Middleware Control.

4 Deploying Applications

Deployment is the process of packaging application files as an archive file and transferring them to a target application server. This chapter describes how to deploy Java EE applications to Oracle Fusion Middleware.

It contains the following topics:

- Overview of Deploying Applications

- Understanding Deployment, Redeployment, and Undeployment

- Understanding and Managing Data Sources

- Deploying and Undeploying Java EE Applications

- Managing Deployment Plans

- Learn More

4.1 Overview of Deploying Applications

Oracle WebLogic Server provides a Java EE-compliant infrastructure for deploying, undeploying, and redeploying Java EE-compliant applications and modules.

You can deploy the following into Oracle WebLogic Server:

- A complete Java EE application packaged as an Enterprise Archive (EAR) file.

- Standalone modules packaged as Java Archive files (JARs) containing Web Services, Enterprise JavaBeans (EJBs), application clients (CARs), or resource adapters (RARs).

- An ADF application. Oracle Application Development Framework (Oracle ADF) is an end-to-end application framework that builds on Java Platform, Enterprise Edition (Java EE) standards, and open-source technologies to simplify and accelerate implementing service-oriented applications.

- An Oracle SOA Suite composite application. A SOA composite application is a single unit of deployment that greatly simplifies the management and lifecycle of SOA applications.

- An Oracle WebCenter application. WebCenter applications differ from traditional Java EE applications in that they support run-time customization, including the application's pages, the portlets contained within these pages, and document libraries.

A Metadata Archive (MAR) is a compressed archive of selected metadata, such as the application-level deployment profile, for an application. A MAR is used to deploy metadata content to the metadata service (MDS) repository. The following application types use a MAR as a container for content that is deployed to the MDS repository: ADF applications, SOA composite applications, and Oracle WebCenter applications.

You can use Fusion Middleware Control, Oracle WebLogic Server Administration Console, Oracle JDeveloper, or the command line to deploy, undeploy, or redeploy an application. Which method you use depends on the type of application, as described in Table 4-1. This chapter describes how to deploy an application using Fusion Middleware Control.

If your application uses an MDS Repository, you must register the repository with the Oracle WebLogic Server domain before you deploy your application. Applications such as custom Java EE applications developed by your organization and some Oracle Fusion Middleware component applications, such as Oracle B2B and Oracle Web Services Manager, use an MDS Repository. For information about the MDS Repository and registering the repository, see "Managing the MDS Repository" in the Oracle Fusion Middleware Administrator's Guide.

4.2 Understanding Deployment, Redeployment, and Undeployment

When you deploy an application, you deploy it to the application server for the first time.

When you redeploy an application, you can:

- Redeploy a new version of the application; the previous version is still available, but the state is set to "Retired."
This is known as the production redeployment strategy. Oracle WebLogic Server automatically manages client connections so that only new client requests are directed to the new version. Clients already connected to the application during the redeployment continue to use the older version of the application until they complete their work, at which point Oracle WebLogic Server automatically retires the older application.

- Redeploy the same version of the application or redeploy an application that is not assigned a version; the application version you select is replaced with the new deployment.

- Redeploy a previous version of the application; the earlier, retired version is set to "Active" and the later version is set to "Retired."

When you undeploy an application, Oracle WebLogic Server stops the application and removes staged files from target servers. It does not remove the original source files used for deployment.

4.3 Understanding and Managing Data Sources

A data source is a Java object that application components use to obtain connections to a relational database. Specific connection information, such as URL or user name and password, are set on a data source object as properties and do not need to be explicitly defined in an application's code. This abstraction allows applications to be built in a portable manner, because the application is not tied to a specific back-end database. The database can change without affecting the application code.

Applications use the Java Naming and Directory Interface (JNDI) API to access a data source object. The application uses a JNDI name that is bound to the data source object. The JNDI name is logical and can be mapped to any data source object. Like data source properties, using JNDI provides a level of abstraction, since the underlying data source object can change without any changes required in the application code. The end result is the details of accessing a database are transparent to the application.

See Also:

Oracle Fusion Middleware Configuring and Managing JDBC for Oracle WebLogic Server for more information about data sources

When you configure certain Oracle Fusion Middleware components, such as Oracle SOA Suite or Oracle WebCenter, using the Oracle WebLogic Server Configuration Wizard, you specify the data source connection information. If the components use the MDS Repository, the Configuration Wizard prepends "mds-" to the data source name to indicate that the data source is a system data source used by MDS Repository.

If you are using Oracle RAC or Oracle Fusion Middleware Cold Failover Cluster, you must configure multi data sources. To do so, you must use the Oracle WebLogic Server Administration Console. Note that if you create a multi data source and you add an existing MDS data source to it, the data source you added is no longer considered a valid MDS repository. The repository is not displayed in Fusion Middleware Control or Oracle WebLogic Server Administration Console. For example, the MDS repository is not listed in the Fusion Middleware Control navigation pane and is not displayed as a choice for a target metadata repository when you deploy an application.

4.3.1 Creating and Managing JDBC Data Sources

You can create and manage JDBC data sources using the following management tools:

- The Oracle WebLogic Server Administration Console

- The WebLogic Scripting Tool (WLST)

- Fusion Middleware Control

To create an MDS data source manually, you should use Fusion Middleware Control or WLST to set the correct attributes for the data source. The MDS data source is displayed in the navigation pane in Fusion Middleware Control and in the domain structure in the Administration Console. If your application uses an MDS Repository, you must register the repository with the Oracle WebLogic Server domain before you deploy your application. For information about the MDS Repository and registering the repository, see "Managing the MDS Repository" in the Oracle Fusion Middleware Administrator's Guide.

See Also:

15. On this page, you can perform common tasks before deploying your application or you can edit the deployment plan or save it to a disk. Depending on the type of application, you can:

- Configure Web modules: This deployment task is available when you are deploying any application that includes a Web module. In most cases, this means the application contains a Web application deployment descriptor (web.xml or weblogic.xml); however, a Web module can also be identified by annotations in the Java code of the application.
You can use this deployment task to set standard Web application deployment descriptor properties, such as:

- Session Validation interval

- Maximum age of session cookies

Click Go to Task in the Configure Web Modules row. The Configure Web Modules page is displayed. Click Configure General Properties to view and edit the general configuration for the Web Module or Map Resource References to map the resource references.

- Configure application security: This deployment task is available for all application types. However, the options available when you select this task vary depending on the existence of the following files in the application:

- If it contains jazn-data.xml, the page displays the Application Policy Migration section.

- If it contains cwallet.sso, the page displays the Application Credential Migration section.

- If it contains both, the page displays both sections.

For information about these settings, see "Deploying JavaEE and ADF Applications with Oracle Enterprise Manager" in the Oracle Fusion Middleware Application Security Guide.

If the application contains neither jazn-data.xml or cwallet.sso, the Configure Application Security page displays the following options:

- Deployment Descriptors Only: Use only roles and policies that are defined in the deployment descriptors.

- Custom Roles: Use roles that are defined in the Administration Console; use policies that are defined in the deployment descriptor.

- Custom Roles and Policies: Use only roles and policies that are defined in the Administration Console.

- Advanced: Use a custom model that you have configured on the realm's configuration page.

Click Go to Task in the Configure Application Security row.

- Configure EJB modules: This deployment task is available for any application that includes an EJB module. In most cases, this means the application contains an EJB deployment descriptor (ejb-jar.xml or weblogic-ejb-jar.xml); however, an EJB module can also be identified by annotations in the Java code of the application.
You can use this deployment task to set standard EJB deployment descriptor properties, such as:

- The maximum number of beans in the free pool

- The EJB network access point

Click Go to Task in the Configure EJB modules row. The Configure EJB Modules page is displayed. Click Configure EJB Properties to view and edit the general configuration for the EJBs or Map Resource References to map the resource preferences.

- Configure ADF Connections: This deployment task is available for applications that use ADF connections. You can modify the connection information for an external application.
Click Go to Task in the Configure ADF Connections row. The Configure ADF Connections page is displayed, showing the current connection information. To modify a connection type, click the Edit icon for a particular row. For example, you can modify the connection information for an external application. For more information about ADF connections, see the Oracle Fusion Middleware Fusion Developer's Guide for Oracle Application Development Framework.

- Configure persistence: This deployment task is available for applications that contain one or more persistence.xml files. Using this task, you can configure the Java Persistent API (JPA) persistence units for the application.
You can view details about each persistence unit and define a Java Transaction API (JTA) data source or non-JTA data source for each persistence unit.

Configuring the data sources for persistence units can be useful for applications that take advantage of Oracle TopLink. For more information, refer to the Oracle Fusion Middleware Developer's Guide for Oracle TopLink.

For more information about how persistence units and the persistence.xml file can be used in Java EE applications, refer to the definition of Persistence Units in the Java EE 5 Tutorial on the Sun Developer Network Web site:

http://java.sun.com/javaee/5/docs/tutorial/doc/bnbqw.html#bnbrj

For a simple Java EE application, only the first three options may be displayed.

16. Expand Deployment Plan.
You can edit and save the deployment plan, if you choose. If you edit the deployment plan and change descriptor values, those changes are saved to the deployment plan. In addition, the following configurations are saved to the deployment plan:

- Application attributes

- Web module configuration

- EJB configuration

Application attributes related to MDS are stored in the file adf-config.xml. Application security attributes are stored in weblogic-application.xml.

Fusion Middleware Control updates the relevant files and repackages the .ear file.

17. Click Deploy.
Fusion Middleware Control displays processing messages.

18. When the deployment is completed, click Close.

To deploy an application to multiple servers at the same time, navigate to the domain. Then, from the WebLogic Domain menu, select Application Deployment, then Deploy. The deployment wizard displays a page where you can select the servers.

- Configure EJB modules

- Configure ADF connections

- Configure persistence

For a simple Java EE application, only the first three options may be displayed.

10. Expand Deployment Plan.
You can edit and save the deployment plan, if you choose. If you edit the deployment plan and change descriptor values, those changes are saved to the deployment plan. In addition, the following configurations are saved to the deployment plan:

- Application attributes

- Web module configuration

- EJB configuration

Application attributes related to MDS are stored in the file adf-config.xml. Application security attributes are stored in weblogic-application.xml.

Fusion Middleware Control updates the relevant files and repackages the .ear file.

11. Click Redeploy.
Processing messages are displayed.

12. When the operation completes, click Close.

To redeploy an application to a cluster, select the cluster. Then, from the target's menu, select Application Deployment, then Redeploy.

WLST Command:

redeploy(app_name [,planpath] [,options])

4.5 Managing Deployment Plans

A deployment plan is a client-side aggregation of all the configuration data needed to deploy an archive into Oracle WebLogic Server. A deployment plan allows you to easily deploy or redeploy an application using a saved set of configuration settings.

A new deployment plan is created by default if you do not apply an existing deployment plan to an application at the time of deployment, as described in Section 4.4.1. Once created, you can save a deployment plan as a file and reuse it for redeploying the application or for deploying other applications.

However, if you change the configuration of an application after it is deployed (for example, if you modify the MDS configuration of an application), then any existing deployment plans you saved no longer represent the configuration settings of the deployed application.

In such a situation, you can fetch a new deployment plan that more closely represents the configuration of the deployed application.

To fetch the deployment plan of an application that is currently deployed:

1. From the navigation pane, expand the farm, then WebLogic Domain.

2. Select the domain.
The WebLogic Domain page is displayed.

3. From the WebLogic Domain menu, choose Application Deployment, then Fetch Deployment Plan.
The Fetch Deployment Plan page is displayed.

4. Select an application from the list of currently deployed applications.

5. Select a location where you want to save the deployment plan, and click Fetch.
You can save the plan to the computer where the Web browser is running or to the computer where Fusion Middleware Control is running.

6. In the resulting dialog box, specify a directory location for the saved deployment plan.
You can now use this deployment plan to later deploy or redeploy the application using the configuration currently in use by the application.

Alternatively, you can edit a deployment plan on the Deployment Settings page of the Application Deployment wizard.

5.1 Overview of Monitoring Oracle Fusion Middleware

Monitoring the health of your Oracle Fusion Middleware environment and ensuring that it performs optimally is an important task for the administrator.

Oracle Fusion Middleware provides the following methods for monitoring the status of your environment:

- Oracle WebLogic Server Administration Console: You can monitor the status of Oracle WebLogic Server domains, clusters, servers, Java components, and applications. From the Administration Console, navigate to the entity's page. See "Overview of the Administration Console" in the Oracle Fusion Middleware Introduction to Oracle WebLogic Server for information on monitoring using the console.

- Fusion Middleware Control: You can monitor the status of Oracle WebLogic Server domains, clusters, servers, Java components, system components, and applications. Navigate to the entity's home page, for example, to the home page for an Oracle HTTP Server instance.

- The command line: You can monitor the status of your environment using the WLST or opmnctl command lines.
To monitor the status of Java components with the command line, use the WLST state command, using the following format:

state(name, type)

For example, to get the status of the Managed Server server1, use the following command:

wls:/mydomain/serverConfig> state('server1','Server')
Current state of "server1": SUSPENDED

To monitor the status of system components with the command line, use the opmnctl status command, using the following format:

opmnctl status  [scope] [options]

For example, to view the status of all processes monitored by OPMN, use the following command:

opmnctl status

You can also view the performance of a components, such as Oracle HTTP Server or Oracle SOA Suite. Navigate to the component and select Monitoring, then Performance Summary from the dynamic target menu.

5.4 Viewing the Routing Topology

Fusion Middleware Control provides a Topology Viewer for the farm. The Topology Viewer is a graphical representation of routing relationships across components and elements of the farm. You can easily determine how requests are routed across components. For example, you can see how requests are routed from Oracle Web Cache, to Oracle HTTP Server, to a Managed Server, to a data source.

Note:

To view relationships between Oracle WebLogic Server, Oracle Web Cache, and Oracle HTTP Server, each target must be running and show its status as Up.

The Topology Viewer enables you to easily monitor your Oracle Fusion Middleware environment. You can see which entities are up and which are down.

You can also print the topology.

To view the topology:

1. Click Topology.
The Topology Viewer is displayed in a separate window.

2. To see information about a particular target, place your mouse over the target. To view additional information, click More.
The following shows the Topology Viewer window, with information about the Managed Server soa_server1:

Description of the illustration topoview.gif

With Topology Viewer, you can also:

- Choose how to group the routing. From the View menu, you can choose to group by Middleware or by application.

- Search for a target within the topology. This makes it easier to find a target if you have many targets. Enter the name in the Find box, and click Find.
The Find results box is displayed. When you click the target name, the target is highlighted. The topology is repositioned so you can see the target if it was not previously visible in the viewing area.

You can also specify criteria for the search. From Find, choose the one or more types of Status or one or more of Target Type, or both.

- View the targets by status. Choose Up, Down, or Unknown from the Target Status at the top of the page.

- Reposition the topology and change its orientation:

- To center the topology. click the Center button.

- To change the orientation, click the top-to-bottom button or the left-to-right button.

- To reposition the topology, click in the topology, but not on a target or route. Drag the topology to position it.

- Navigate to the home page of a target. Right-click the target, and select Home.

- Perform operations directly on the target by right-clicking. The right-click target menu is displayed. For example, from this menu, you can start or stop an Oracle WebLogic Server or view additional performance metrics.

- View the routing relationships between components. For example, you can view the routing from Oracle Web Cache to Oracle HTTP Server to Oracle WebLogic Server. Clicking on the line between the two targets displays the URLs used.

- From the Refresh dropdown, you can refresh manually, or you can enable automatically refreshing the status and metrics, every minute, every five minutes, or every thirty minutes. By default, the Topology Viewer refreshes the metrics every 5 minutes.

- To change what is visible in the topology view, drag the shaded section in the navigator window, which is located in the bottom right.

- Hide or show the status or metrics. From Annotations, click Status or Metrics.
If you select Metrics, one key performance metric for the component is displayed. (You cannot change the metric that is displayed.)

Notes:

- If you use Mozilla Firefox, when you click a link or menu item in the Topology Viewer to navigate back to the main Fusion Middleware Control window, the main window does not always get focus. For example, if you right-click a target node and select View Log Messages from the target menu, the focus remains on the Topology Viewer window. (If you go back to the main window, the Log Messages page is correctly displayed.)
To work around this problem, make the following change in Firefox:

From the Tools menu, select Options, and then Content. Click Advanced. In the Advanced JavaScript Settings dialog box, select Raise and lower windows.

- If you use Internet Explorer, turn off the Always Open Popups in New Tab option.

5.5 Viewing Port Numbers

By default, Oracle Fusion Middleware assigns port numbers to various components and services during installation or when you create a component. (You can specify particular ports during installation and configuration.) You can view the assigned port numbers from the Port Usage page of Fusion Middleware Control.

You can view the port numbers of the Oracle WebLogic Server domain, the Administration Server, Managed Servers, or components, such as the SOA Infrastructure and Oracle Web Cache, using Fusion Middleware Control.

To view the port numbers that are currently used by a WebLogic domain:

1. From the navigation pane, expand the farm, then WebLogic Domain.

2. Select the domain.

3. From the WebLogic Domain menu, choose Port Usage.
The Port Usage page is displayed, as shown in the following figure:

Description of the illustration ports.gif

Optionally, you can filter the ports shown by selecting a Managed Server from Show.

2. From the navigation pane, select Security Realms.
The Summary of Security Realms page is displayed.

3. Select a realm, such as myrealm.
The Settings for the realm page is displayed.

4. Select the Users and Groups tab, then the Users tab. Select the user.
The Settings for user page is displayed.

5. Select the Passwords tab.

6. Enter the new password, then enter it again to confirm it.

7. Click Save.

6.4 Configuring SSL

SSL secures communication by providing message encryption, integrity, and authentication. The SSL standard allows the involved components (such as browsers and HTTP servers) to negotiate which encryption, authentication, and integrity mechanisms to use.

- Encryption provides confidentiality by allowing only the intended recipient to read the message. SSL can use different encryption algorithms to encrypt messages. During the SSL handshake that occurs at the start of each SSL session, the client and the server negotiate which algorithm to use. Examples of encryption algorithms supported by SSL include AES, RC4, and 3DES.

- Integrity ensures that a message sent by a client is received intact by the server, untampered. To ensure message integrity, the client hashes the message into a digest using a hash function and sends this message digest to the server. The server also hashes the message into a digest and compares the digests. Because SSL uses hash functions that make it computationally infeasible to produce the same digest from two different messages, the server can tell that if the digests do not match, then someone had tampered with the message. An example of a hash function supported by SSL is SHA1.

- Authentication enables the server and client to check that the other party is who it claims to be. When a client initiates an SSL session, the server typically sends its certificate to the client. Certificates are digital identities that are issued by trusted certificate authorities, such as Verisign.
The client verifies that the server is authentic and not an imposter by validating the certificate chain in the server certificate. The server certificate is guaranteed by the certificate authority (CA) who signed the server certificate.

The server can also require the client to have a certificate, if the server needs to authenticate the identity of the client.

This section describes the following topics:

- Understanding Keystores and Wallets

- Enabling SSL Between a Browser and Oracle HTTP Server

6.4.1 Understanding Keystores and Wallets

In Oracle Fusion Middleware, all Java components and applications use the JKS keystore. Thus all Java components and applications running on Oracle WebLogic Server use the JKS-based KeyStore and TrustStore.

The Oracle Virtual Directory system component uses a JKS keystore to store keys and certificates. Configuring SSL for Oracle Virtual Directory thus requires setting up and using JKS keystores.

Other components use the Oracle wallet as their storage mechanism. An Oracle wallet is a container that stores your credentials, such as certificates, trusted certificates, certificate requests, and private keys. You can store Oracle wallets on the file system or in LDAP directories such as Oracle Internet Directory. Oracle wallets can be auto-login or password-protected wallets.

The following components use Oracle wallet:

- Oracle HTTP Server

- Oracle Web Cache

- Oracle Internet Directory

6.4.2 Enabling SSL Between a Browser and Oracle HTTP Server

You can enable SSL on the communication path between a client browser and a Web server. In this case, you configure the virtual host for Oracle HTTP Server to listen in SSL mode, as described in the following topics:

- Enabling SSL for Inbound Traffic to Oracle HTTP Server Virtual Hosts

- Enabling SSL for Outbound Traffic from Oracle HTTP Server Virtual Hosts

6.4.2.1 Enabling SSL for Inbound Traffic to Oracle HTTP Server Virtual Hosts

To enable SSL for inbound traffic to Oracle HTTP Server virtual hosts:

1. Create an Oracle wallet:

1. In the navigation pane, expand the farm, then Web Tier. Select an Oracle HTTP Server instance.

2. From the Oracle HTTP Server menu, choose Security, then Wallets.
The Wallets page is displayed.

3. Click Create.
The Create Wallet page is displayed, as shown in the following figure:

Description of the illustration create_wallet.gif

4. For Wallet Name, enter a descriptive wallet name.

5. Check or uncheck Autologin, depending on whether your wallet is an auto-login wallet. The default is an auto-login wallet. If you do not check Autologin, for Wallet Password, enter a password, then enter the same password in Confirm Password.

6. Click OK to create the wallet.
A confirmation box is displayed.

7. The confirmation box asks if you want to create a certificate request. Click Yes.
The Create Wallet: Add Certificate Request page is displayed.

8. For Common Name, enter a name for the certificate request.

9. Enter information about your organization.

10. For Key Size, select a size.

11. Click OK.

12. To get the certificate signed by a certificate authority (CA), you must export the certificate request out of the wallet and send it to your CA. After the issued certificate is returned, you must import it back into your wallet. Now your wallet is ready to use.

2. From the HTTP Server menu, choose Administration, then Virtual Hosts.
The Virtual Hosts page is displayed.

3. Select a virtual host and choose Configure, then SSL Configuration.
The SSL Configuration page is displayed, as shown in the following figure:

Description of the illustration ohsssl3.gif

4. Select Enable SSL.

5. For Server Wallet Name, select the wallet.

6. From the Server SSL properties, select the SSL Authentication type, Cipher Suites to use, and the SSL protocol version.

7. Click OK.

8. Restart Oracle HTTP Server. (From the Oracle HTTP Server menu, choose Control, then Restart.)

9. Now, you can test this by visiting the Oracle HTTP Server page over SSL in a browser. Use a URL of the form https://host:port/, where you replace the host and port with values relevant to your own environment.

6.4.2.2 Enabling SSL for Outbound Traffic from Oracle HTTP Server Virtual Hosts

Outbound requests from Oracle HTTP Server are handled by configuring mod_wl_ohs.

To configure outbound requests for SSL:

1. Generate a custom keystore for Oracle WebLogic Server containing a certificate, using the Oracle WebLogic Server Administration Console:

1. In the left pane of the Console, expand Environment and select Servers.

2. Select Configuration, then Keystores.

3. Define the keystore. See the online help for information about each field.

2. Import the certificate used by Oracle WebLogic Server into the Oracle HTTP Server wallet as a trusted certificate. You can use any available utility such as WLST or Fusion Middleware Control for this task.

3. Edit the Oracle HTTP Server configuration file ORACLE_INSTANCE/config/OHS/ohs1/ssl.conf and add the following line to the SSL configuration under mod_weblogic:

WlSSLWallet  "$(ORACLE_INSTANCE}/config/COMPONENT_TYPE/COMPONENT_NAME/default"

In the line, default is the name of the Oracle HTTP Server wallet in Step 2.

Here is an example of the configuration:

<IfModule mod_weblogic.c>
WebLogicHost myhost.example.com
WebLogicPort 7002
Debug ALL
WLLogFile /tmp/weblogic.log
MatchExpression *.jsp
SecureProxy On
WlSSLWallet "$(ORACLE_INSTANCE)/config/OHS/ohs1/keystores/default"
</IfModule>

Save the file and exit.

4. Restart Oracle HTTP Server to activate the changes.

5. Ensure that your Oracle WebLogic Server instance is configured to use the custom keystore generated in Step 1, and that the alias points to the alias value used in generating the certificate. Restart the Oracle WebLogic Server instance.

7 Managing Log Files

Oracle Fusion Middleware components generate log files containing messages that record all types of events, including startup and shutdown information, errors, warning messages, access information on HTTP requests, and additional information. This chapter describes how to view and manage log files to assist in monitoring system activity and in diagnosing system problems.

This chapter contains the following topics:

- Overview of Logging in Oracle Fusion Middleware

- Viewing Log Messages and Summaries

- Viewing Log Files

- Searching Log Files

- Downloading Log Files

- Configuring Log Settings

- Learn More

7.1 Overview of Logging in Oracle Fusion Middleware

Most Oracle Fusion Middleware components write diagnostic log files in the Oracle Diagnostic Logging (ODL) format. Log file naming and the format of the contents of log files conforms to an Oracle standard. By default, the diagnostic messages are written in text format.

ODL provides the following benefits:

- The capability to limit the total amount of diagnostic information saved.

- Older segment files are removed and newer segment files are saved in chronological fashion.

- Components can remain active, and do not need to be shutdown, when older diagnostic logging files are deleted.

Note:

Oracle WebLogic Server does not use the ODL format. For information about the Oracle WebLogic Server log format, see Oracle Fusion Middleware Configuring Log Files and Filtering Log Messages for Oracle WebLogic Server.

7.2 Viewing Log Messages and Summaries

You can view the messages for all of the entities in a domain, a Managed Server, a component, or an application.

To view the log files and their messages for a Managed Server:

1. From the navigation pane, expand the farm, then WebLogic Domain, and then the domain. Right-click the Managed Server name and choose Logs, then View Log Messages.
The Log Messages page is displayed, as shown in the following figure:

Description of the illustration logpage.gif

By default, this page shows the Incident Error and Error messages that occurred in the last hour. You can modify the criteria to include other message types or other time intervals.

By default, the messages are sorted by time, in ascending order. You can sort the messages by any of the columns, such as message type, by clicking the column name.

2. To view a summary of the messages, in the table, for Show, select Group by Message Type or Group by Message ID.

7.6 Configuring Log Settings

You can change the log settings of Managed Servers and Java components using Fusion Middleware Control or WLST.

Note:

You cannot use Fusion Middleware Control or WLST to configure options for log files of system components, which are listed in Section 2.4.2.

To change log file settings using Fusion Middleware Control, navigate to the component's home page and choose Logs, then Log Configuration from the dynamic target menu.

You can configure the following options:

- The names and paths of log files. See Section 7.6.1.

- The size of log files: You can specify that a new file is created either when the log file reaches a certain size or when a particular time is reached. This is called log file rotation. See Section 7.6.2.

- The log level: You can specify the amount and type of information written to log files. See Section 7.6.3.

- The log file format: You can specify whether the logs are written in text or XML format. See Section 7.6.4.

7.6.1 Changing Log File Names and Locations

By default, Oracle Fusion Middleware writes log files for Java components to the following directories:

(UNIX) MW_Home/user_projects/domains/domain_name/servers/server_name/logs
(Windows) MW_Home\user_projects\domains\domain_name\servers\server_name\logs

The default name of a log file is server_name-diagnostic.log.

For example, the log files for Oracle SOA Suite are:

(UNIX) MW_Home/user_projects/domains/domain_name/servers/server_name/logs/server_name-diagnostic.log
(Windows) MW_Home\user_projects\domains\domain_name\servers\server_name\logs\server_name-diagnostic.log

You can change the name and location of a server or component. To change the name and location of a log file using Fusion Middleware Control, navigate to the entity's home page and choose Logs, then Log Configuration from the dynamic target menu.

For example, to change the name and location of the Oracle WebCenter Spaces log file using Fusion Middleware Control:

1. From the navigation pane, expand the entities and select WebCenter Spaces.

2. From the WebLogic Server menu, choose Logs, then Log Configuration.
The Log Configuration page is displayed.

3. Select the Log Files tab.

4. In the table, select the log handler and click Edit Configuration.
The Edit Log File dialog box is displayed, as shown in the following figure:

Description of the illustration logedit3.gif

5. For Log Path, enter a new path.

6. Click OK.

7. In the confirmation window, click Close.

WLST Command:

configureLogHandler(name='log_handler_name', path='path')

7.6.2 Configuring Log File Rotation

An ODL log is a set of log files that includes the current ODL log file and zero or more ODL Archives (segment files) that contain older messages. As the log file grows, new information is added to the end of the log file, server_name-diagnostic.log. When the log file reaches the rotation point, it is renamed and a new log file, server_name-diagnostic.log is created. You specify the rotation point, by specifying the maximum ODL segment size or the rotation time and rotation frequency.

Segment files are created when the ODL log file server_name-diagnostic.log reaches the rotation point. That is, the server_name-diagnostic.log is renamed to server_name-diagnostic-n.log, where n is an integer, and a new server_name-diagnostic.log file is created when the component generates new diagnostic messages.

By default, the log files are rotated when they reach 10 MB. The maximum size of all log files for a particular component is 100 MB.

To change log file rotation for a component, navigate to the component's home page in Fusion Middleware Control and choose Logs, then Log Configuration from the dynamic target menu.

To configure log file rotation based on size:

1. From the navigation pane, expand the farm, and select the target, such as a Managed Server.

2. From the dynamic target menu, choose Logs, then Log Configuration.
The Log Configuration page is displayed.

3. Select the Log Files tab.

4. In the table, select the logger and click Edit Configuration.
The Edit Log File dialog box is displayed.

5. In the Rotation Policy section, select Size Based.

6. For Maximum Log File Size, enter the size in MB, for example, 15.

7. For Maximum Size of All Log Files, enter the size in MB, for example, 150.

8. Click Apply.

To configure log file rotation based on time:

1. From the navigation pane, expand the farm, and select the target, such as a Managed Server.

2. From the dynamic target menu, choose Logs, then Log Configuration.
The Log Configuration page is displayed.

3. Select the Log Files tab.

4. In the table, select the logger and click Edit Configuration.
The Edit Log File dialog box is displayed.

5. In the Rotation Policy section, select Time Based.

6. For Start Time, click the calendar and select the date and time when you want the rotation to start. For example, select September 8, 2010 6:00 AM.

7. For Frequency, you can select Minutes and enter the number of minutes, or you can select Hourly, Daily, or Weekly. In this case, select Hourly. The log files will be rotated each hour.

8. For Retention Period, you can specify how long the log files are kept. You can select Minutes and enter the number of minutes, or you can specify Day, Week, Month, or Year. In this case, select Month.
Specifying a shorter period means that you will use less disk space, but will not be able to retrieve older information.

9. Click OK.

WLST Command:

configureLogHandler(name='log_handler_name', rotationFrequency='frequency',
baseRotationTime='time', retentionPeriod=minutes)

7.6.3 Setting Log Levels

You can configure the amount and type of information written to log files by specifying the message type and level. For each message type, possible values for message level are from 1 (highest severity) through 32 (lowest severity). The lower severity levels write more information to the log files. Generally, you need to specify only the type; you do not need to specify the level.

When you specify the type, Oracle Fusion Middleware returns all messages of that type, as well as the messages that have a higher severity. For example, if you set the message type to WARNING, Oracle Fusion Middleware also returns messages of type INCIDENT_ERROR and ERROR.

Table 7-1 shows the message types and the most common levels for each type.

Table 7-1 Diagnostic Message Types and Level

Message Type

Level

Description

INCIDENT_ERROR

1

A serious problem that may be caused by a bug in the product and that should be reported to Oracle Support.

Examples are errors from which you cannot recover or serious problems.

ERROR

1

A serious problem that requires immediate attention from the administrator and is not caused by a bug in the product.

An example is if Oracle Fusion Middleware cannot process a log file, but you can correct the problem by fixing the permissions on the document.

WARNING

1

A potential problem, such as invalid parameter values or a specified file that does not exist, that should be reviewed by the administrator.

NOTIFICATION

1

A major lifecycle event such as the activation or deactivation of a primary sub-component or feature.

This is the default level for NOTIFICATION.

NOTIFICATION

16

A finer level of granularity for reporting normal events.

TRACE

1

Trace or debug information for events that are meaningful to end users of the product, such as public API entry or exit points.

TRACE

16

Detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem.

TRACE

32

Very detailed trace or debug information that can help Oracle Support diagnose problems with a particular subsystem.

You can set the message level for a particular log file or for loggers. To change message level, navigate to the component's home page in Fusion Middleware Control and choose Logs, then Log Configuration from the dynamic target menu.

To set the message level for a component log file:

1. From the navigation pane, expand the farm, and select the target.

2. From the dynamic target menu, choose Logs, then Log Configuration.
The Log Configuration page is displayed.

3. Select the Log Files tab.

4. In the table, select the log file and click Edit Configuration.

Description of the illustration logedit.gif

5. For Log Level, select the logging level. For example, select NOTIFICATION:1 (INFO).

6. Click OK.

7. In the confirmation window, click Close.

To set the message level for one or more loggers for a component:

1. From the navigation pane, expand the farm, and select the target.

2. From the dynamic target menu, choose Logs, then Log Configuration.
The Log Configuration page is displayed.

3. Select the Log Levels tab, which is shown in the following figure:
Description of the illustration logedit2.gif

4. For View, select Runtime Loggers or Loggers with Persistent Log Level State.
Run-time loggers are loggers that are currently active. Persistent loggers are loggers that are saved in a configuration file and log levels of these loggers are persistent across component restarts. A run-time logger can also be a persistent logger, but not all run-time loggers are persistent loggers.

5. In the table, to specify the same level for all loggers, select the logging level for the top-level logger. Then, for child loggers that do not specify that the logging level is inherited from the parent, specify Inherited from Parent. For most situations, that is sufficient.
However, if you need to specify the level for a particular logger, expand the logger and then, for the logger that you want to modify, select the logging level. For example, for the logger oracle.wsm.management.logging, select WARNING:1 (WARNING).

6. Click Apply.

WLST Command:

setLogLevel(target='target_name, logger='log_handler_name',
level='type[:level]' [,runtime=0_or_1], [,persist=0_or_1])

7.6.4 Specifying the Log File Format

By default, information is written to log files in ODL text format. You can change the format to ODL XML format.

8 Backing Up and Recovering Oracle Fusion Middleware

Backup and recovery refers to the strategies and procedures involved in guarding against hardware failures and data loss, and reconstructing data should a loss occur.

This chapter contains the following topics:

- Overview of Backup and Recovery

- Backing Up Your Environment

- Recovering After Data Loss, Corruption, or Media Failure

- Creating a Record of Your Oracle Fusion Middleware Configuration

- Learn More

8.1 Overview of Backup and Recovery

An Oracle Fusion Middleware environment can consist of different components and configurations. A typical Oracle Fusion Middleware environment contains an Oracle WebLogic Server domain with Java components, such as Oracle SOA Suite, and a WebLogic Server domain with Identity Management components. It can also include Oracle instances containing system components such as Oracle HTTP Server, Oracle Web Cache, Oracle Internet Directory, and Oracle Virtual Directory.

The installations of an Oracle Fusion Middleware environment are interdependent in that they contain configuration information, applications, and data that are kept in synchronization. For example, when you perform a configuration change, information in configuration files is updated. When you deploy an application, you might deploy it to all Managed Servers in a domain or cluster.

It is, therefore, important to consider your entire Oracle Fusion Middleware environment when performing backup and recovery. You should back up your entire Oracle Fusion Middleware environment at once, then periodically. If a loss occurs, you can restore your environment to a consistent state.

8.1.1 Understanding Backup Operations

To back up your Oracle Fusion Middleware environment, you can use:

- File copy utilities such as copy, xcopy, tar, or jar:

- On Windows, for online backups, use copy; for offline backups, use copy, xcopy, or jar. Do not use Winzip because it does not work with long filenames or extensions.
Note that for some versions of Windows, any file name with more than 256 characters will fail. You can use the xcopy command with the following switches to work around this issue:

xcopy /s/e  "C:\Temp\*.*"  "C:\copy"

See the xcopy help for more information about syntax and restrictions.

- On Linux and UNIX, for online and offline backups, use tar.
The following example shows how to archive and compress the source on UNIX:

cd Source_Middleware_Home
tar cf - * | gzip > mw_home_backup_092010.tar.gz

The tar utility may issue warnings if the sticky bit is set on some files. You can safely ignore these warnings.

Do not use the jar utility to archive and compress the file system. This avoids warnings or errors from the zip tool about zipping open files (for example, the ORACLE_HOME/jdk files).

Ensure that the tool you are using preserves the permissions of the files.

- Oracle Recovery Manager (RMAN) to back up database-based metadata repositories.

If you want to retain your backups for a longer duration, you may want to back up to tape, for example using Oracle Secure Backup.

You can also configure Oracle WebLogic Server to make backup copies of the configuration files. This facilitates recovery in cases where configuration changes need to be reversed or in the unlikely case that configuration files become corrupted. When the Administration Server starts, it saves a .jar file named config-booted.jar that contains the configuration files. When you make changes to the configuration files, the old files are saved in the configArchive directory under the domain directory, in a .jar file with a sequentially numbered name such as config-1.jar. However, the configuration archive is always local to the Administration Server host. It is a best practice to back up the archives to an external location.

8.1.1.1 Types of Backups

- An offline backup means that you must shut down the environment before backing up the files. When you perform an offline backup, the Administration Server, all Managed Servers in the domain, and all system components in the Oracle instances should be shut down.
Back up the environment offline immediately after installation and after applying any patches or upgrades.

- An online backup means that you do not shut down the environment before backing up the files. To avoid an inconsistent backup, do not make any configuration changes until the backup is completed. To ensure that no changes are made in the Oracle WebLogic Server domain, lock the WebLogic Server configuration, as described in Section 2.3.2.

You can perform backups on your full Oracle Fusion Middleware environment, or on the run-time artifacts, those files that change frequently.

To perform a full backup, you should back up the static files and directories, as well as run-time artifacts.

Static files and directories are those that do not change frequently. These include:

- The Middleware home (MW_HOME). A Middleware home consists of a WebLogic Server home (the Oracle WebLogic Server product directories), an Oracle Common home, and optionally an Oracle home. It can also contain the user_projects directories, which contains Oracle WebLogic Server domains, and Oracle instance homes, which are not static files.

- OraInventory

- OraInst.loc and oratab files, which are located in the following directory:

/etc

- The beahomelist file, which is located at:

(UNIX) user_home/bea/beahomelist
(Windows) C:\bea\beahomelist

- On Windows, the following registry key:

HKEY_LOCAL_MACHINE\Software\Oracle

In addition, for system components, such as Oracle Web Cache, you must back up the following Windows Registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

Run-time artifacts are those files that change frequently. Back up these files when you perform a full backup and on a regular basis. Run-time artifacts include:

- Domain directories of the Administration Server and the Managed Servers (by default, a domain directory resides in MW_HOME, but it can be configured by the user to point to a different location)
In most cases, you do not need to back up Managed Server directories separately because the Administration Server contains information about all of the Managed Servers in its domain.

- All Oracle instance homes, which reside, by default, in the MW_HOME but can be configured to be in a different location

- Application artifacts, such as .ear or .war files that reside outside of the domain
You do not need to backup application artifacts in a Managed Server domain because they can be retrieved from the Administration Server during Managed Server startup.

- Database artifacts such as the MDS repository

- Any database-based metadata repositories used by Oracle Fusion Middleware. You use Oracle Recovery Manager (RMAN) to back up an Oracle database

- Persistent stores, such as JMS Providers and transaction logs, which reside, by default in the user_projects directory, but can be configured in a different location

8.1.1.2 Recommended Backup Strategy

This section outlines the recommended strategy for performing backups. Using this strategy ensures that you will be able to perform the recovery procedures in this book.

- Perform a full offline backup. This involves backing up the entities described in Section 8.1.1.1. Perform an offline full backup at the following times:

- Immediately after you install Oracle Fusion Middleware

- Immediately after an operating system software upgrade

- Immediately after upgrading or patching Oracle Fusion Middleware

- Perform an online backup of run-time artifacts. This involves backing up the run-time artifacts described in Section 8.1.1.1. Backing up the run-time artifacts enables you to restore your environment to a consistent state as of the time of your most recent configuration and metadata backup. To avoid an inconsistent backup, do not make any configuration changes until backup completes. Perform an online backup of run-time artifacts at the following times:

- On a regular basis. Oracle recommends that you back up run-time artifacts nightly.

- Prior to making configuration changes to a component or cluster.

- After making configuration changes to a component or cluster.

- Prior to deploying a custom Java EE application to a Managed Server or cluster.

- After a major change to the deployment architecture, such as creating servers or clusters.

- Perform an offline backup of static files and directories. This involves backing up the static files and directories described in Section 8.1.1.1. Perform an offline backup of static files and directories at the following times:

- After patching your Oracle Fusion Middleware environment. This backup serves as the basis for subsequent online backups.

- After upgrading your Oracle Fusion Middleware environment. This backup serves as the basis for subsequent online backups.

- If any of the following files are modified:

MW_HOME/wlserver_n/common/bin/nodemanager.properties
MW_HOME/wlserver_n/common/bin/wlsifconfig.sh
MW_HOME/wlserver_n/common/bin/setPatchEnv.sh
MW_HOME/wlserver_n/common/bin/commEnvg.sh

To avoid an inconsistent backup, do not make any configuration changes until the backup is completed. To ensure that no changes are made in the Oracle WebLogic Server domain, lock the Oracle WebLogic Server configuration, as described in Section 2.3.2.

8.1.2 Understanding Recovery Operations

Recovery strategies enable you to recover from critical failures that involve actual data loss. Depending on the type of loss, they can involve recovering any combination of the following types of files:

- Oracle software files

- Configuration files

- Metadata repository files

- Oracle system files

- Windows Registry key

- Application artifacts

You can recover your Oracle Fusion Middleware environment while Oracle Fusion Middleware is offline.

To recover your Oracle Fusion Middleware environment, you can use:

- File copy utilities such as copy, xcopy, or tar
When you restore the files, use your preferred tool to extract the compressed files:

- On Windows, for online recovery, use copy; for offline recovery, use copy, xcopy, or jar.
Note that for some versions of Windows, any file name with more than 256 characters will fail. You can use the xcopy command with the following switches to work around this issue:

xcopy /s/e  "C:\Temp\*.*"  "C:\copy"

See the xcopy help for more information about syntax and restrictions.

Do not use Winzip because it does not work with long filenames or extensions.

- On Linux and UNIX, use tar.

Ensure that the tool you are using preserves the permissions and timestamps of the files.

- Oracle Recovery Manager (RMAN) to recover database-based metadata repositories

8.1.2.1 Types of Recovery

You can recover your Oracle Fusion Middleware environment in part or in full. You can recover the following:

- The Middleware home

- An Oracle WebLogic Server domain

- The Oracle WebLogic Server Administration Server

- A Managed Server

- An Oracle home

- An Oracle instance

- A component, such as Oracle SOA Suite or Oracle Web Cache

- A cluster

- Deployed applications

8.1.2.2 Recommended Recovery Strategies

Note the following key points about recovery:

- Your Oracle Fusion Middleware environment must be offline while you are performing recovery.

- Rename important existing files and directories before you begin restoring the files from backup so that you do not unintentionally override necessary files.

- Although, in some cases, it may appear that only one or two files are lost or corrupted, you should restore the directory structure for the entire element, such as an Oracle instance or a component, rather than just restoring one or two files. In this way, you are more likely to guarantee a successful recovery.

- Recover the database to the most current state, using point-in-time recovery (if the database is configured in Archive Log Mode). This is typically a time right before the database failure occurred.

8.2 Backing Up Your Environment

The following topics describe how to perform different types of backups:

- Performing a Full Offline Backup

- Performing an Online Backup of Run-Time Artifacts

8.2.1 Performing a Full Offline Backup

To perform a full offline backup, you copy the directories that contain Oracle Fusion Middleware files.

Archive and compress the source Middleware home, using your preferred tool for archiving. Ensure that the tool you are using preserves the permissions of the files, as described in Section 8.1.1.

The following example shows how to archive and compress the Middleware home on Linux:

cd Middleware_Home
tar cf - * | gzip > Middleware_Home.tar.gz

The tar utility may issue warnings if the sticky bit is set on some files. You can safely ignore these warnings.

To perform a full offline backup:

1. Shut down all processes in the Middleware home. For example, shut down the Managed Servers, the Administration Server, and any Oracle instances running in the Middleware home.

2. Back up the Middleware home (MW_HOME) on all hosts. For example:

tar -cf mw_home_backup_092010.tar MW_HOME/*

3. If the domain is not located within the Middleware home, back up the Administration Server domain separately. This backs up Java components such as Oracle SOA Suite and Oracle WebCenter.
For example:

tar -cf domain_home_backup_092010.tar MW_HOME/user_projects/domains/domain_name/*

In most cases, you do not need to backup the Managed Server directories separately, because the Administration Server domain contains information about the Managed Servers in its domain.

4. If the Oracle instance home is not located within the Middleware home, back up the Oracle instance home. The Oracle instance home contains configuration information about system components, such as Oracle HTTP Server or Oracle Internet Directory. (See Section 2.4.2 for a list of system components.)
For example:

tar -cf instance_home_backup_092010.tar ORACLE_INSTANCE/*

5. If a Managed Server is not located within the domain directory, back up the Managed Server directory. For example:

tar -cf mg1_home_backup_092010.tar MW_HOME/user_projects/domains/domain_name/servers/server_name/*

6. Backup the OraInventory directory. For example:

tar -cf Inven_home_backup_092010 /scratch/oracle/OraInventory

7. Back up OraInst.loc and oratab files, which are located in the following directory:

/etc

8. Backup the database repositories using the Oracle Recovery Manager (RMAN). For detailed steps, see the Oracle Database Backup and Recovery User's Guide, which is available at:

http://www.oracle.com/technology/documentation/database.html

9. On Windows, export the following registry key:

HKEY_LOCAL_MACHINE\Software\Oracle

In addition, for system components, such as Oracle Web Cache, export the following Windows Registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services

To export a key, use the following command:

regedit /E  FileName Key

For example:

regedit /E C:\oracleregistry.reg HKEY_LOCAL_MACHINE/oracle

You can also use the Registry Editor to export the key. See the Registry Editor Help for more information.

10. Create a record of your Oracle Fusion Middleware environment. See Section 8.4.

8.2.2 Performing an Online Backup of Run-Time Artifacts

You should perform a backup of run-time artifacts on a regular basis and at the times described in Section 8.1.1.2.

To back up run-time artifacts:

1. To avoid an inconsistent backup, do not make any configuration changes until the backup is completed. To ensure that no changes are made in the Oracle WebLogic Server domain, lock the WebLogic Server configuration, as described in Section 2.3.2.

2. Back up the Administration Server domain directories. This backs up Java components such as Oracle SOA Suite and Oracle WebCenter. For example:

tar -cf domain_home_backup_092010.tar MW_HOME/user_projects/domains/domain_name/*

For Oracle Portal, Oracle Reports, Oracle Forms Services, and Oracle Business Intelligence Discoverer, you must back up the Managed Server domain directories, in addition to the Administration Server domain.

3. Back up the Oracle instance home. This backs up the system components, such as Oracle HTTP Server. For example:

tar -cf instance_home_backup_092010.tar ORACLE_INSTANCE/*

4. Backup the database repositories using the Oracle Recovery Manager (RMAN). For detailed steps, see the Oracle Database Backup and Recovery User's Guide, which is available at:

http://www.oracle.com/technology/documentation/database.html

5. Create a record of your Oracle Fusion Middleware environment. See Section 8.4.

8.3 Recovering After Data Loss, Corruption, or Media Failure

This section describes recovery strategies for outages that involve actual data loss or corruption, or media failure where the disk cannot be restored. This type of failure requires some type of data restoration before the Oracle Fusion Middleware environment can be restarted and continue with normal processing. It contains the following topics:

- Recovering a Middleware Home

- Recovering an Oracle WebLogic Server Domain

- Recovering the Administration Server Configuration

- Recovering a Managed Server

- Recovering an Oracle Home

- Recovering an Oracle Instance

- Recovering Components

For information about recovering after the loss of a host, see "Recovery After Loss of Host" in the Oracle Fusion Middleware Administrator's Guide.

8.3.1 Recovering a Middleware Home

You can recover a Middleware home that was corrupted or from which files were deleted.

To recover a Middleware home:

1. Stop all relevant processes. That is, stop all processes that are related to the domain, such as the Administration Server, Node Manager, and Managed Servers. For example, to stop the Administration Server on Linux:

DOMAIN_HOME/bin/stopWeblogic.sh username password [admin_url]

2. Recover the Middleware home directory from backup. For example:

cd MW_HOME
(UNIX) tar -xf mw_home_backup_092010.tar
(Windows) jar xtf mw_home_backup_092010.jar

3. Start all relevant processes. That is, start all processes that run in that Middleware home. For example, to start the Administration Server:

DOMAIN_HOME/bin/startWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password
-Dweblogic.system.StoreBootIdentity=true

8.3.2 Recovering an Oracle WebLogic Server Domain

You can recover an Oracle WebLogic Server domain that was corrupted or deleted from the file system.

Caution:

Performing a domain-level recovery can impact other aspects of a running system and all of the configuration changes performed after the backup was taken will be lost.

To recover an Oracle WebLogic Server domain:

1. Stop all relevant processes. That is, stop all processes that are related to the domain, such as the Administration Server and Managed Servers. For example, stop the Administration Server:

DOMAIN_HOME/bin/stopWeblogic.sh username password [admin_url]

2. Recover the domain directory from backup. For example:

cd MW_HOME/user_projects/domains/domain_name
(UNIX) tar -xf domain_backup_092010.tar
(Windows) jar xtf domain_backup_092010.jar

3. Start all relevant processes. That is, start all processes that are related to the domain. For example, start the Administration Server:

DOMAIN_HOME/bin/startWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password
-Dweblogic.system.StoreBootIdentity=true

4. If you cannot start the Administration Server, recover it, as described in Section 8.3.3.

5. If you cannot start a Managed Server, recover it, as described in Section 8.3.4.

8.3.3 Recovering the Administration Server Configuration

If the Administration Server configuration has been lost because of file deletion or file system corruption, the Administration Server console continues to function if it was already started when the problem occurred. The Administration Server directory is regenerated automatically, except for security information. As a result, whenever you start the Administration Server, it prompts for a user name and password. To prevent this, you can recover the configuration.

Caution:

Performing a domain-level recovery can impact other aspects of a running system and all of the configuration changes performed after the backup was taken will be lost.

To recover the Administration Server configuration:

1. Stop all processes, including the Administration Server, Managed Servers, and Node Manager if they are started. For example, to stop the Administration Server on Linux, use the following script:

DOMAIN_HOME/bin/stopWeblogic.sh username password admin_url

2. Recover the Administration Server configuration by recovering the domain home backup to a temporary location. Then, restore the config directory to the following location:

MW_HOME/user_projects/domains/domain_name/config

3. Start the Administration Server. You can use WLST or the following script:

DOMAIN_HOME/bin/startWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password
-Dweblogic.system.StoreBootIdentity=true

4. Verify that the Administration Server starts properly and is accessible.

On the next configuration change, the configuration from the Administration Server is pushed to the Managed Servers. On each Managed Server restart, the configuration is retrieved from the Administration Server.

8.3.4 Recovering a Managed Server

In this scenario, the Managed Server does not operate properly or cannot be started because the configuration has been deleted or corrupted or the configuration was mistakenly changed and you cannot ascertain what was changed.

To recover a Managed Server when it cannot be started:

1. If the Administration Server is not reachable, recover the Administration Server, as described in Section 8.3.3.

2. If the Managed Server fails to start or if the file system is lost, take the following steps:

1. Recover the Middleware home from the backup, if required. For example:

tar -xf mw_home_backup_092010.tar

2. Create a domain template jar file for the Administration Server, using the pack utility. For example:

pack.sh -domain=MW_HOME/user_projects/domains/domain_name
-template=/scratch/temp.jar -template_name=test_install
-template_author=myname -log=/scratch/logs/my.log -managed=true

Specifying the -managed=true option packs up only the Managed Servers. If you want to pack the entire domain, omit this option.

3. Unpack the domain template jar file, using the unpack utility:

unpack.sh -template=/scratch/aime1/ms.jar
-domain=MW_HOME/user_projects/domains/domain_name
-log=/scratch/logs/new.log -log_priority=info

4. Ensure that the application artifacts are accessible from the Managed Server host. That is, if the application artifacts are not on the same server as the Managed Server, they must be in a location accessible by the Managed Server.

Note:

- For stage mode applications, the Administration Server takes care of pushing the bits to the stage directories in the Managed Server.

- For no-stage and external-stage applications, ensure that application files are available in the stage directories of the Managed Server.

See Oracle Fusion Middleware Deploying Applications to Oracle WebLogic Server for information about stage, no-stage, and external-stage mode applications.

5. Start the Managed Server. You can use the Oracle WebLogic Server Administration Console, WLST, or the following script:

DOMAIN_HOME/bin/startManagedWebLogic.sh managed_server_name
admin_url

The Managed Server connects to the Administration Server and updates its configuration changes.

8.3.5 Recovering an Oracle Home

You can recover an Oracle home, which contains binary files for particular components.

To recover your Oracle home for a particular component:

1. Recover the Oracle home to the original directory from a backup file. For example:

cd ORACLE_HOME
tar -xf Oracle_home_backup_031509.tar

2. Restart the Managed Server to which applications are deployed using the WLST start command. For example:

wls:/mydomain/serverConfig> start('myserver','Server')

8.3.6 Recovering an Oracle Instance

An Oracle instance home contains configuration information for system components, such as Oracle HTTP Server or Oracle Internet Directory. (See Section 2.4.2 for a list of system components.)

The following topics describe how to recover an Oracle instance:

- Recovering After Oracle Instance Home Deleted from File System

- Recovering After Oracle Instance Home Deregistered

8.3.6.1 Recovering After Oracle Instance Home Deleted from File System

You can recover an Oracle instance home after it was corrupted or erroneously deleted from the file system.

To recover an Oracle instance home that was corrupted or deleted from the file system:

1. Stop all relevant processes. That is, stop all processes that are related to that Oracle instance.

2. Recover the Oracle instance home directory from a backup file. For example:

cd ORACLE_INSTANCE
(UNIX) tar -xf Instance_home_backup_092010.tar
(Windows) jar xtf Instance_home_backup_092010.jar

3. Start all relevant processes. That is, start all processes that are related to that Oracle instance:

opmnctl startall

8.3.6.2 Recovering After Oracle Instance Home Deregistered

You can recover an Oracle instance home after it was erroneously deregistered from the domain.

To recover an Oracle instance home that was deregistered:

1. Recover the Oracle instance home directory from a backup file. For example, on Linux:

cd ORACLE_INSTANCE
tar -xf Instance_home_backup_092010.tar

2. Register the Oracle instance, along with all of its components, with the Administration Server, using the opmnctl registerInstance command. For example:

opmnctl registerInstance -adminHost admin_server_host
-adminPort admin_server_port -adminUsername username
-adminPassword password
-oracleInstance ORACLE_INSTANCE_dir -oracleHome ORACLE_HOME_dir
-instanceName Instance_name -wlserverHome Middleware_Home

8.3.7 Recovering Components

For most components, the following topics describe how to recover a component:

- Recovering After Component's Files Are Deleted or Corrupted

- Recovering Components After Cluster Configuration Change

For information about additional actions you may need to take to recover particular components, see "Recovering Components" in the Oracle Fusion Middleware Administrator's Guide.

8.3.7.1 Recovering After Component's Files Are Deleted or Corrupted

You can restore a component's files if they are deleted or corrupted or if the component cannot be started or is not functioning properly because the component's configuration was changed and committed. You may not be able to ascertain what change is causing the problem and you want to revert to an earlier version.

To recover a component, the steps you take depend on the type of component:

- For Java components, such as Oracle SOA Suite, you recover the Managed Server, as described in Section 8.3.4.

- For system components, such as Oracle HTTP Server or Oracle Web Cache:

1. Stop the component. For example, to stop Oracle HTTP Server:

opmnctl stopproc ias-component=HTTP_Server

For more information on stopping components, see Section 3.4.4.

2. Recover the component-specific files from backup. See the Oracle Fusion Middleware Administrator's Guide for a list of the directories and files needed for each component. For example, to recover Oracle HTTP Server files, you recover the following directories:

ORACLE_INSTANCE/config/OHS/component_name
ORACLE_INSTANCE/diagnostics/logs/OHS/component_name
ORACLE_INSTANCE/tmp/OHS/component_name

3. Start the component. For example, to start Oracle HTTP Server:

opmnctl startproc ias-component=HTTP_Server

For more information on starting components, see Section 3.4.4.

8.3.7.2 Recovering Components After Cluster Configuration Change

You can recover components in a cluster when the components cannot be started or are not functioning properly because the configuration was changed and committed at the cluster level. You may not be able to ascertain what change is causing the problem and you want to revert to an earlier version.

Caution:

Performing a domain-level recovery can impact other aspects of a running system and all of the configuration changes performed after the backup was taken will be lost.

To recover the components:

1. Stop the cluster:

stop('cluster_name', 'Cluster')

2. Stop all processes, such as the Managed Servers and the Administration Server. For example, to stop the Administration Server on Linux, use the following script:

DOMAIN_HOME/bin/stopWeblogic.sh username password admin_url

3. Recover the Administration Server configuration by recovering the domain home backup to a temporary location. Then, restore the config directory to the following location:

MW_HOME/user_projects/domains/domain_name/config

4. Start the Administration Server. You can use WLST or the following script:

DOMAIN_HOME/bin/startWebLogic.sh -Dweblogic.management.username=username
-Dweblogic.management.password=password
-Dweblogic.system.StoreBootIdentity=true

5. Start the cluster. You can use the Oracle WebLogic Server Administration Console or WLST. For example, to use the WLST start command:

start('clusterName', 'Cluster')

The latest configuration is retrieved from the Administration Server to every member of the cluster.

8.4 Creating a Record of Your Oracle Fusion Middleware Configuration

In the event you need to restore and recover your Oracle Fusion Middleware environment, it is important to have all the necessary information at your disposal. This is especially true in the event of a hardware loss that requires you to reconstruct all or part of your Oracle Fusion Middleware environment on a new disk or host.

You should maintain an up-to-date record of your Oracle Fusion Middleware environment that includes the information listed in this section. You should keep this information both in hardcopy and electronic form. The electronic form should be stored on a host or e-mail system that is completely separate from your Oracle Fusion Middleware environment.

Your Oracle Fusion Middleware hardware and software configuration record should include:

- The following information for each host in your environment:

- Host name

- Virtual host name (if any)

- Domain name

- IP address

- Hardware platform

- Operating system release level and patch information

- The following information for each Oracle Fusion Middleware installation in your environment:

- Installation type (for example, Oracle SOA Suite)

- Host on which the installation resides

- User name, userid number, group name, groupid number, environment profile, and type of shell for the operating system user that owns the Oracle home (/etc/passwd and /etc/group entries)

- Directory structure, mount points, and full path for the Middleware home, Oracle home, Oracle WebLogic Server domain home (if it does not reside in the user_projects directory in the Middleware home), and the Oracle instance home

- Amount of disk space used by the installation

- Port numbers used by the installation

- The following information for the Metadata Repository:

- Host name

- Database version and patch level

- Base language

- Character set

- Global database name

- SID

- Listen port

8.5 Learn More

For more information about backing up and recovering Oracle Fusion Middleware, see the following topics in the Oracle Fusion Middleware Administrator's Guide:

- "Introducing Backup and Recovery," which provides more in-depth information about backup and recovery strategies

- "Backup Strategies and Procedures," which provides additional information about backing up your environment

- "Recovery Strategies and Procedures," which provides additional information about selective recovery of Oracle WebLogic Server instances, Oracle instances, components, and applications. It also explains how to recover in the case of loss of host.

9 Scaling Your Environment

You can expand your environment by adding Managed Servers, expanding your WebLogic Server domain to include other products, or cloning existing Oracle Fusion Middleware components such as Oracle SOA Suite or Oracle HTTP Server, or existing Middleware homes as described by the following topics:

- Overview of Scaling Your Environment

- Extending a WebLogic Server Domain to Support Additional Components

- Adding Additional Managed Servers to a WebLogic Server Domain

- Creating Clusters

- Cloning a Middleware Home or Component

- Learn More

9.1 Overview of Scaling Your Environment

Scalability is the ability of a system to provide throughput in proportion to, and limited only by, available hardware resources. A scalable system is one that can handle increasing numbers of requests without adversely affecting response time and throughput.

The growth of computational power within one operating environment is called vertical scaling. Horizontal scaling is leveraging multiple systems to work together on a common problem in parallel.

Oracle Fusion Middleware scales both vertically and horizontally. Horizontally, Oracle Fusion Middleware can increase its throughput with several Managed Servers grouped together to share a workload. Also, Oracle Fusion Middleware provides great vertical scalability, allowing you to add more Managed Servers or components in the same host.

High availability refers to the ability of users to access a system. Deploying a high availability system minimizes the time when the system is down (unavailable) and maximizes the time when it is running (available). Oracle Fusion Middleware is designed to provide a wide variety of high availability solutions, ranging from load balancing and basic clustering to providing maximum system availability during catastrophic hardware and software failures.

High availability solutions can be divided into two basic categories: local high availability and disaster recovery.

See Also:

- Oracle Fusion Middleware High Availability Guide for more information about high availability

- Oracle Fusion Middleware Disaster Recovery Guide

9.2 Extending a WebLogic Server Domain to Support Additional Components

When you create an Oracle WebLogic Server domain, you create it using a particular domain template. That template supports a particular component or group of components, such as the Oracle SOA Suite. If you want to add other components, such as Oracle WebCenter, to that domain, you can extend the domain by creating additional Managed Servers in the domain, using a domain template for the component which you want to add.

See Also:

The table "Supported Domain Extensions" in the Oracle Fusion Middleware Administrator's Guide for information about which components you can add to an existing domain and the domain templates needed

When you extend a domain, the domain must be offline.

To extend a domain, you use the Oracle WebLogic Server Configuration Wizard from an Oracle home into which the desired component has been installed. Then, you select the domain that you want to extend and the component you want to add.

For example, to extend a domain that was initially created to support Oracle SOA Suite so that it can now also support Oracle WebCenter:

1. Use RCU to add any required schemas for the component, as described in Section 3.2.1.

2. Install Oracle WebCenter, as described in the Oracle Fusion Middleware Installation Guide for Oracle WebCenter.

3. From an Oracle home that was installed for the component you want to add, (for example, for Oracle WebCenter), invoke the Configuration Wizard, using the following command:

(UNIX) ORACLE_HOME/common/bin/config.sh
(Windows) ORACLE_HOME\common\bin\config.cmd

The Configuration Wizard's Welcome screen is displayed.

4. Select Extend an existing WebLogic Domain.

5. Click Next.
The Select a WebLogic Domain Directory screen is displayed.

6. Select the directory for the domain to which you want to add the components.

7. Click Next.
The Select Extension Source screen is displayed.

8. Select Extend my domain automatically to support the following added products, Then, select the source from which this domain is to be extended. For example, select Oracle WebCenter Spaces.

9. Click Next.
The Configure JDBC Data Sources screen is displayed.

10. Select the schemas for the new component you added, entering the following information:

- For Vendor, select Oracle.

- For Driver, select Oracle's Driver (Thin) for Service connections; Versions:9.0.1,9.2.0,10,11.

- For Schema Owner, do not enter anything. Each data source uses the user name specified in the table.

- If you used the same password when you created the schemas, select all of the schemas and enter the password in Schema Password.
Alternatively, you can specify different passwords for each data source by selecting each schema individually and entering the password.

- With all of the schemas selected, for DBMS/Service, enter the SID of the database.

- With all of the schemas selected, for Host Name, enter the host name of the database.

- With all of the schemas selected, for Port, enter the listening port of the database.

11. Click Next.
The Test Component Schema screen is displayed.

12. If the test succeeds, click Next.
The Select Optional Configuration screen is displayed.

13. In this and the following customization screens, you can choose to customize. To do so, select the type of customization. If you do not want to customize the settings, click Next.
The Configuration Summary screen is displayed.

14. Review the information on the screen and if it is correct, click Extend.

15. When the operation completes, click Done.

Oracle WebLogic Server Administration Console Online Help for more information about creating additional Managed Servers

9.3 Adding Additional Managed Servers to a WebLogic Server Domain

You can add Managed Servers to a domain to increase the capacity of your system. The Managed Servers can be added to a cluster.

When a Managed Server is added to a cluster, it inherits the applications and services that are targeted to the cluster. When a Managed Server is added to a domain, it does not automatically inherit the applications and services from the template.

To add a Managed Server to a domain, you can use the Oracle WebLogic Server Administration Console or WLST.

See:

Administration Console Online Help and Oracle Fusion Middleware WebLogic Scripting Tool Command Reference for complete information about adding Managed Servers

To create an additional Managed Server using the Administration Console:

1. Display the Administration Console, as described in Section 2.3.1.

2. Lock the Oracle WebLogic Server configuration, as described in Section 2.3.2.

3. In the left pane, expand Environment, then select Servers.

4. In the Servers table, click New.
The Create a New Server: Server Properties page is displayed.

5. Enter the following information:

- For Name, enter a name for the server.
Each server within a domain must have a name that is unique for all configuration objects in the domain. Within a domain, each server, computer, cluster, JDBC connection pool, virtual host, and any other resource type must be named uniquely and must not use the same name as the domain.

- For Listen Address, if you want to limit the valid addresses for a server instance, enter an IP address or DNS name. Otherwise, URLs to the server can specify the host computer's IP address, any DNS name that maps to one of the IP addresses, or the localhost string.

- For Listen Port, enter the port number from which you want to access the server instance.
If you run multiple server instances on a single computer, each server must use its own listen port.

- Specify whether or not this server will be a standalone server or will belong to an existing cluster or a new cluster.

- If this server is to be a standalone server, select No, this is a stand-alone server.

- If this server is to be part of an existing cluster, select Yes, make this server a member an existing cluster. Then, select the cluster.
This option is not shown if there are no existing clusters.

- If this server is to be part of a new cluster, select Yes, create a new cluster for this server.

6. Click Next.
The Review Choices page is displayed.

7. Review the information. If it is correct, click Finish.

8. Apply Oracle JRF to the Managed Server or cluster as described in Section 9.3.1.

Note that you can also use Fusion Middleware Control to add a Managed Server to a domain. From the Farm menu, choose Create/Delete Components. Then, in the Fusion Middleware Components page, select Create, then WebLogic Server.

9.3.1 Applying Oracle JRF to a Managed Server or Cluster

Oracle JRF (Java Required Files) consists of those components not included in the Oracle WebLogic Server installation and that provide common functionality for Oracle business applications and application frameworks.

JRF consists of a number of independently developed libraries and applications that are deployed into a common location. The components that are considered part of Java Required Files include Oracle Application Development Framework shared libraries and ODL logging handlers.

You must apply the JRF template to a Managed Server or cluster in certain circumstances. You can only apply JRF to Managed Servers that are in a domain in which JRF was configured. That is, you must have selected Oracle JRF in the Configuration Wizard when you created or extended the domain.

Note the following points about when you apply JRF:

- When you add a Managed Server to an existing cluster that is already configured with JRF, you do not need to apply JRF to the Managed Server.

- When you add a Managed Server to a domain and the Managed Server requires JRF services, but the Managed Server is not part of a cluster, you must apply JRF to the Managed Server.

- When you create a new cluster and the cluster requires JRF, you must apply JRF to the cluster.

- You do not need to apply JRF to Managed Servers that are added by product templates during the template extension process (though you must select JRF in the Configuration Wizard).

- You must restart the server or cluster after you apply JRF.

- If you create a server using Fusion Middleware Control, the JRF template is automatically applied.

You use the custom WLST command applyJRF to configure the Managed Servers or cluster with JRF. To use the custom WLST commands, you must invoke the WLST script from the Oracle Common home. See Section 2.4.1.1 for more information.

The format of the applyJRF command is:

applyJRF(target={server_name | cluster_name | *}, domainDir=domain_path
[,shouldUpdateDomain= {true | false}])

You can use the applyJRF command online or offline:

- In online mode, the JRF changes are implicitly activated if you use the shouldUpdateDomain option with the value true (which is the default.) In online mode, this option calls the online WLST save() and activate() commands.

- In offline mode, you must restart the Administration Server and the Managed Servers or cluster. (In offline mode, if you specify the shouldUpdateDomain option with the value true, this option calls the WLST updateDomain() command.)

To configure a Managed Server with JRF, use the following command:

applyJRF(target='server1', domainDir='/scratch/Oracle/Middleware/user_projects/domains/domain1')

To configure all Managed servers in the domain with JRF, specify an asterisk (*) as the value of the target option.

To configure a cluster with JRF, use the following command:

applyJRF(target='cluster', domainDir='/scratch/Oracle/Middleware/user_projects/domains/domain1')

See Also:

- "Java Required Files Custom WLST Commands" in the Oracle Fusion Middleware WebLogic Scripting Tool Command Reference

- "Using a Different Version of Spring" in the Oracle Fusion Middleware Administrator's Guide to use a different version of Spring than that which is supplied with JRF

9.4 Creating Clusters

A WebLogic Server cluster consists of multiple WebLogic Server server instances running simultaneously and working together to provide increased scalability and reliability. A cluster appears to clients to be a single WebLogic Server instance. The server instances that constitute a cluster can run on the same computer, or be located on different computers. You can increase a cluster's capacity by adding additional server instances to the cluster on an existing computer, or you can add computers to the cluster to host the incremental server instances. Each server instance in a cluster must run the same version of WebLogic Server.

You can create a cluster of Managed Servers using WLST, the Oracle WebLogic Server Administration Console, or Fusion Middleware Control. This section describes how to create a cluster using Fusion Middleware Control.

Note:

For Identity Management components, Oracle Portal, Oracle Forms Services, Oracle Reports, and Oracle Business Intelligence Discoverer, if one or more Managed Servers that you want to include in a cluster is on a remote host, the WebLogic Server home must have the same full path as the WebLogic Server home of the other Managed Servers.
For example, you have a Managed Server on Host A and a Managed Server on Host B, and you want to include them in a cluster. If the WebLogic Server home on Host A is located in /scratch/oracle/Middleware/wlserver_10.3, the WebLogic Server home on Host B must also be located in /scratch/oracle/Middleware/wlserver_10.3.

To create a cluster of two Managed Servers, soa_server1 and soa_server2, using Fusion Middleware Control:

1. From the Farm menu, choose Create/Delete Components.
The Fusion Middleware Components page is displayed.

2. Choose Create, then WebLogic Cluster.
The Create WebLogic Cluster page is displayed.

3. For Name, enter a name for the cluster.

4. In the Cluster Messaging Mode section, select one of the following:

- Unicast. Then, for Unicast Broadcast Channel, enter a channel. This channel is used to transmit messages within the cluster.

- Multicast. Then, for Multicast Broadcast Channel, enter a channel. A multicast address is an IP address in the range from 224.0.0.0 to 239.255.255.255. For Multicast Port, enter a port number.

Note:

You must ensure that the multicast address is not in use.

5. In the Servers section, select one or more servers to be added to the cluster. In this scenario, select soa_server1 and soa_server2.

6. Click Create.

Now, you have a cluster with two members, soa_server1 and soa_server2.

See Also:

Oracle Fusion Middleware Using Clusters for Oracle WebLogic Server for more information about clusters

If you create a server using Fusion Middleware Control, the JRF template is automatically applied.

9.5 Cloning a Middleware Home or Component

You can expand your environment to meet growing demands by cloning existing Middleware homes and Oracle homes and some components.

Cloning is the process of copying an existing entity to a different location while preserving its state. The cloned entity behaves the same as the source entity. For example, a cloned Oracle home can be deinstalled or patched using the installer. It can also be used as the source for another cloning operation.

You can clone the following, on the same host or a different host. The clone must be on the same operating system as the source.

- Middleware home: You can clone the Middleware home, the Oracle WebLogic Server home, and all of the Oracle homes within the Middleware home. You can clone a Middleware home that contains no Oracle homes.
You can apply the clone of the Middleware home to the same host or a different host.

- Java components: You can clone the configuration of a domain containing Java components, such as Oracle SOA Suite and Oracle Business Activity Monitoring to the same or a different Middleware home, on the same host or a different host.

- System components: You can clone the configuration of a domain containing system components, such as Oracle HTTP Server and Oracle Internet Directory, to the same or a different Oracle instance, to the same or a different Middleware home, on the same host or a different host.

You use the following scripts to clone a Middleware home or component:

- Copy the source Middleware home:

(UNIX) ORACLE_COMMON_HOME/bin/copyBinary.sh
(Windows) ORACLE_COMMON_HOME\bin\copyBinary.cmd

- Apply the copied Middleware home to the target:

(UNIX) ORACLE_COMMON_HOME/bin/pasteBinary.sh
(Windows) ORACLE_COMMON_HOME\bin\pasteBinary.cmd

- Copy the source component configuration:

(UNIX) ORACLE_COMMON_HOME/bin/copyConfig.sh
(Windows) ORACLE_COMMON_HOME\bin\copyConfig.cmd

- Extract a move plan from the source component:

(UNIX) ORACLE_COMMON_HOME/bin/extractMovePlan.sh
(Windows) ORACLE_COMMON_HOME\bin\extractMovePlan.cmd

- Apply the copied component configuration to the target:

(UNIX) ORACLE_COMMON_HOME/bin/pasteConfig.sh
(Windows) ORACLE_COMMON_HOME\bin\pasteConfig.cmd

Note that all cloning scripts ask if you want to continue whenever you do not specify the -silent true option. To continue, you must type yes, which is not case sensitive. Any words other than yes causes the script to return an error. Also note that, in silent mode, the scripts generate an error if you do not provide passwords where they are needed.

To specify additional Java options, define the T2P_JAVA_OPTIONS environment variable and specify the options in the variable definition. The following examples set the value for the Java temp directory:

- On Linux or UNIX:

setenv T2P_JAVA_OPTIONS "-Djava.io.tmpdir=/home/t2p/temp"
export T2P_JAVA_OPTIONS="-Djava.io.tmpdir=/home/t2p/temp"

- On Windows:

set T2P_JAVA_OPTIONS="-Djava.io.tmpdir=c:\home\sasinsin\temp"

See Also:

"Cloning Oracle Fusion Middleware" in the Oracle Fusion Middleware Administrator's Guide for complete information about cloning, including the syntax

Note:

If you are applying the clone of a Middleware home on a host that does not yet have Oracle Fusion Middleware installed, note the following

- The host must have JDK 1.6.04 or higher installed. In addition, ensure that the PATH, CLASSPATH, and JAVA_HOME environment variables point to the JDK.

- Copy the pasteBinary script from the following location in the source host to the target host:

(UNIX) ORACLE_COMMON_HOME/bin/pasteBinary.sh
(Windows) ORACLE_COMMON_HOME\bin\pasteBinary.cmd

- Copy the following file from the following location in the source host to the target host:

(UNIX) ORACLE_COMMON_HOME/jlib/cloningclient.jar
(Windows) ORACLE_COMMON_HOME\jlib\cloningclient.jar

- If you run the pasteBinary script from a different location than ORACLE_COMMON_HOME/bin, then the pasteBinary script and the cloningclient.jar file must be in the same directory.

- Ensure that the files have execute permission.

9.5.1 Cloning a Middleware Home

You can clone a Middleware home, which can contain zero or more Oracle homes and an Oracle WebLogic Server home.

Note:

- The cloning operation archives only those Oracle homes that lie within a Middleware home. It does not clone Oracle homes that are located outside of the Middleware home.

- You can clone only one Middleware home at a time.

- If Oracle WebLogic Server is not located in the Middleware home, the Oracle WebLogic Server home is not archived and cloned, but any Oracle homes in the Middleware home are archived and cloned.

- On Windows, ensure that no Oracle WebLogic Server processes are running in the source Middleware home.

- If the target host does not contain the file oraInst.loc, you must create the file (you must have Super User or root privileges). By default, the clone operation looks for the file in the /etc directory. If you create it in another location, use the -invPtrLoc parameter to the pasteBinary command to specify the location.
The file must contain the following:

inventory_loc=oraInventory_location
inst_group=user_group

To clone a Middleware home:

1. On Windows, at the source Middleware home, stop the Administration Server and any Managed Servers running in the Middleware home.

2. At the source Middleware home, execute the copyBinary script, which finds the WebLogic Server home and the Oracle homes contained within the Middleware home. If there are no Oracle homes in the Middleware home, no Oracle homes will be present in the archive.
For example, to clone a Middleware home that is located at /scratch/Oracle /Middleware1, use the following command:

copyBinary.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/mw_clone.jar
-sourceMWHomeLoc /scratch/Oracle/Middleware1
-invPtrLoc /scratch/oracle/oraInst.loc

3. If you are cloning the Middleware home to a different host, copy the archive file to that system.

4. Copy the pasteBinary scripts and the cloningclient.jar file to the target system and ensure that they have execute permission. See Section 9.5 for the locations of the files.
Do not copy the other scripts, such as pasteConfig. Those scripts are generated when you extract the files, as in step 5.

5. At the target, extract the files from the archive using the pasteBinary script.
For example, to apply the clone to the directory /scratch/oracle/MW_Home_clone, use the following command:

pasteBinary.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc  /tmp/mw_clone.jar
-targetMWHomeLoc  /scratch/oracle/MW_Home_clone

The Middleware home is extracted to /scratch/oracle/MW_Home_clone and the WebLogic Server home and all of the Oracle homes are extracted under it with the same names as that of the source Oracle home names.

9.5.2 Customizing Move Plans When Cloning Components

When you clone Oracle Fusion Middleware components, you run the extractMovePlan script to create a move plan for the component that you are cloning. The extractMovePlan script extracts configuration information from the archive into a move plan. It also extracts any needed configuration plans. Before you apply the clone to the target, you must edit the move plan to reflect the values of the target environment.

The following shows an excerpt of a move plan for WebLogic Java components:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<movePlan>
<movableComponent>
<componentType>J2EEDomain</componentType>
<moveDescriptor>
<configProperty>
<name>Startup Mode</name>
<value>PRODUCTION</value>
<itemMetadata>
<dataType>STRING</dataType>
<scope>READ_WRITE</scope>
</itemMetadata>
</configProperty>
<configGroup>
<type>SERVER_CONFIG</type>
<configProperty id="Server1">
<configProperty>
<name>Server Name</name>
<value>AdminServer</value>
<itemMetadata>
<dataType>STRING</dataType>
<scope>READ_ONLY</scope>
</itemMetadata>
</configProperty>
<configProperty>
<name>Listen Address</name>
<value>example.com</value>
<itemMetadata>
<dataType>STRING</dataType>
<scope>READ_WRITE</scope>
</itemMetadata>
</configProperty>

You can modify properties with the scope of READ_WRITE. Do not modify the properties with the scope of READ_ONLY.

The properties that you edit differ depending on the type of component. See the table in "Customizing Move Plans When Cloning Components" in the Oracle Fusion Middleware Administrator's Guide for information about the properties to edit for each type of component.

9.5.3 Cloning Java Components

You can clone WebLogic Java components, such as Oracle SOA Suite.

To clone a WebLogic Java component:

1. At the source Middleware home, make sure that the Administration Server and all Managed Servers are started.

2. At the source Middleware home, execute the copyConfig command.
For example, to clone the Oracle SOA Suite domain named SOA_domain1 in the in the Middleware home /scratch/Oracle/Middleware1, use the following command:

copyConfig.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/soa.jar
-sourceDomainLoc /scratch/Oracle/Middleware1/user_projects/domains/SOA_domain1
-sourceMWHomeLoc /scratch/Oracle/Middleware1
-domainHostName example.com
-domainPortNum 8001
-domainAdminUserName admin_username
-domainAdminPassword /scratch/admin/passwd.txt
-logDirLoc /tmp/logs

3. If you are cloning the component to a different host, copy the archive file to that system.

4. Extract the move plan from the archive, using the extractMovePlan script. For example:

extractMovePlan.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/soa.jar
-planDirLoc /tmp/Oracle/t2p_plans/soa

5. Edit the move plan, modifying the properties in described in the tables in "Move Plans for Components" in the Oracle Fusion Middleware Administrator's Guide.

6. At the target, extract the files from the archive using the pasteConfig script. For example, to apply the clone to the Middleware home /scratch/Oracle/Middleware1, use the following command:

pasteConfig.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/soa.jar
-movePlanLoc /tmp/Oracle/t2p_plans/soa/moveplan.xml
-targetDomainLoc /scratch/Oracle/Middleware1/user_projects/domains/SOA_domain1
-targetMWHomeLoc /scratch/Oracle/Middleware1/
-domainAdminPassword /scratch/pwd_dir/pass.txt

9.5.4 Cloning System Components

You can clone the system components, such as Oracle HTTP Server or Oracle Virtual Directory.

To clone a system component:

1. At the source Middleware home, make sure that the Administration Server and all Managed Servers are started.

2. At the source Middleware home, execute the copyConfig command.
For example, to clone the Oracle HTTP Server instance named ohs1 in the Oracle instance located in /scratch/Oracle/Middleware1/webtier_1, use the following command:

copyConfig.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/ohs1.jar
-sourceInstanceHomeLoc /scratch/Oracle/Middleware1/webtier_1
-sourceComponentName ohs1

3. If you are cloning the component to a different host, copy the archive file to that system.

4. Extract the move plan from the archive, using the extractMovePlan script. For example:

extractMovePlan.sh -javaHome /scratch/Oracle/Middleware1/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/ohs1.jar
-planDirLoc /tmp/Oracle/t2p_plans/ohs

5. Edit the move plan, modifying the properties in described in the tables in "Move Plans for Components" in the Oracle Fusion Middleware Administrator's Guide.

6. At the target, extract the files from the archive using the pasteConfig script. For example, to apply the clone to the Oracle instance webtier_2 and name the cloned Oracle HTTP Server instance ohs_cl, use the following command:

pasteConfig.sh -javaHome /scratch/Oracle/Middleware/jrockit_160_20_D1.1.0-18
-archiveLoc /tmp/ohs1.jar
-movePlanLoc /tmp/Oracle/t2p_plans/ohs/moveplan.xml
-targetOracleHomeLoc /scratch/Oracle/Middleware/Oracle_WebTier
-targetInstanceHomeLoc /scratch/Oracle/Middleware/webtier_2
-targetInstanceName webtier_2
-targetComponentName ohs_cl
-domainHostName myhost
-domainPortNum 7001
-domainAdminUserName domain_admin_username
-domainAdminPassword domain_admin_password_file
