14 Extending the Domain with Oracle Service Bus

The procedures described in this chapter guide you through the process of extending the enterprise deployment topology with Oracle Service Bus (OSB).

Parent topic: Configuring the Enterprise Deployment

14.1 About Configuring Oracle Service Bus in Its Own Domain

When adding Oracle Service Bus to your enterprise topology, you can add it to the existing SOA domain, or you can create a new domain for Oracle Service Bus, separate from the Oracle SOA Suite domain.

For more information, see About the Topology Options for Oracle Service Bus.

If you decide to configure Oracle Service Bus in a separate domain, then keep in mind the following when you are using the instructions for adding Oracle Service Bus to your topology:

  • Ignore any references to the SOA Managed Servers or the SOA Cluster. These elements of the domain will only exist if you are extending a domain that has already been extended with Oracle SOA Suite.

  • You must run the Repository Creation Utility (RCU) to create the SOAINFRA schema for the Oracle Service Bus domain. This schemas is required by Oracle Service Bus. You must use a unique SOAINFRA schema and schema prefix for the Oracle Service Bus domain.

14.2 Variables Used When Configuring Oracle Service Bus

As you perform the tasks in this chapter, you will be referencing the directory variables listed in this section.

The values for several directory variables are defined in File System and Directory Variables Used in This Guide.

  • ORACLE_HOME

  • ASERVER_HOME

  • MSERVER_HOME

  • JAVA_HOME

  • OHS_DOMAIN_HOME

In addition, you'll be referencing the following virtual IP (VIP) addresses defined in Physical and Virtual IP Addresses Required by the Enterprise Topology:

  • ADMINVHN

Actions in these topics will be performed on the following host computers:

  • SOAHOST1

  • SOAHOST2

  • WEBHOST1

  • WEBHOST2

14.3 Overview of Adding OSB to the Topology

Before you add OSB to the topology, you must ensure that you have already performed the steps required to create an initial Infrastructure domain and then you have extended the domain to include Oracle SOA suite.

Table 14-1 lists and describes the high-level steps for extending an existing SOA domain or an existing Infrastructure domain for Oracle Service Bus.

Table 14-1 Steps for Extending a SOA Domain to Include Oracle Service Bus

Step Description More Information

Install Oracle Service Bus software

Install OSB software on the target system.

Installing Oracle Service Bus Software

Optionally, install the SOAINFRA schema in a supported database.

OSB requires the SOAINFRA schema for the wlsbjmsrpDataSource data source. If you are planning to run OSB in its own domain, then you must be sure that you have installed a separate SOAINFRA schema for OSB in a supported database.

Be sure to use a unique schema for the SOAINFRA schema that will be used by the OSB domain.

Creating the Oracle SOA Suite Database Schemas

Optionally, create a new Infrastructure domain.

If you are planning to run OSB in its own domain, then you must first create an Infrastucture domain, so you can extend that domain with OSB.

Creating the Initial Infrastructure Domain for an Enterprise Deployment

Run the Configuration Wizard to Extend the Domain

Extend the SOA or Infrastructure domain to contain Oracle Service Bus components.

Extending the SOA or Infrastructure Domain to Include Oracle Service Bus

Configure a Default Persistence Store for Transaction Recovery

To leverage the migration capability of the Transaction Recovery Service for the servers within a cluster, store the transaction log in a location accessible to a server and its backup servers.

Configuring a Default Persistence Store for Transaction Recovery

Propagate the Domain Configuration to the Managed Server Directory in SOAHOST1 and to SOAHOST2

Oracle Service Bus requires some updates to the WebLogic Server start scripts. Propagate these changes using the pack and unpack commands.

Propagating the Extended Domain to the Domain Directories and Machines

Start the Oracle Service Bus Servers

Oracle Service Bus servers extend an already existing domain. As a result, the Administration Server and respective Node Managers are already running in SOAHOST1 and SOAHOST2.

Starting and Validating the WLS_OSB1 Managed Server

Validate the WLS_OSB Managed Servers

Verify that the server status is reported as Running in the Admin Console and access URLs to verify status of servers.

Starting and Validating the WLS_OSB2 Managed Server

Configuring Oracle HTTP Server for the WLS_OSBn Managed Servers

To enable Oracle HTTP Server to route to Oracle Service Bus console and Oracle Service Bus service, set the WebLogicCluster parameter to the list of nodes in the cluster.

Configuring Oracle HTTP Server for the Oracle Service Bus

Validating Access Through Oracle HTTP Server

Verify that the server status is reported as Running.

Validating the Oracle Service Bus URLs Through the Load Balancer

Enable High Availability for Oracle File and FTP Adapters

Make Oracle File and FTP Adapters highly available for outbound operations using the database mutex locking operation.

Enabling High Availability for Oracle DB_ File and FTP Adapters

Backing up the Oracle Service Bus Configuration

To back up the domain configuration for immediate restoration in case of failures in future procedures.

Backing Up the Oracle Service Bus Configuration

14.4 Prerequisites for Extending the Domain to Include Oracle Service Bus

Before extending the current domain, ensure that your existing deployment meets the necessary prerequisites.

  • Back up the installation - If you have not yet backed up the existing Fusion Middleware Home and domain, Oracle recommends backing it up now.

    To back up the existing Fusion Middleware Home and domain, see Performing Backups and Recoveries in the SOA Enterprise Deployments.

  • Verify that you have installed the Infrastructure and SOA software binaries in an Oracle home on shared storage and they are available from SOAHOST1 and SOAHOST2.

  • If Oracle Service Bus is being configured in the same domain as SOA, then the appropriate SOAINFRA schema (used by the wlsbjmsrpDataSource) will be already available. If OSB is being configured in its own domain, then you must run RCU to install the SOAINFRA schema in a supported database, using a different schema prefix than the SOAINFRA schema used by the SOA domain.

  • You have already configured Node Manager, Administration Server, (optionally SOA Servers) and WSM Servers as described in previous chapters to run a SOA system. Optionally, you may have already configured Server migration, transaction logs, coherence, and all other configuration steps for the SOA System.

  • If you haven't done so already, verify that the system clocks on each host computer are synchronized. You can do this by running the date command as simultaneously as possible on the hosts in each cluster.

    Alternatively, there are third-party and open-source utilities you can use for this purpose.

14.5 Installing Oracle Service Bus Software

You can install Oracle Service Bus in an enterprise deployment by using the OSB Installer.

14.5.1 Starting the Oracle Service Bus Installer

To start the installation program, perform the following steps.

  1. Log in to the target system, SOAHOST1.
  2. Go to the directory in which you downloaded the installation program.
  3. Set the path for the java executable: 
    export JAVA_HOME=JAVA_HOME
export PATH=$JAVA_HOME/bin:$PATH

    In this example, replace JAVA_HOME with the value this variable listed in File System and Directory Variables Used in This Guide and entered in the Enterprise Deployment Workbook.

  4. Launch the installation program by entering the following command: 
    java -d64 -jar fmw_12.2.1.2_osb.jar

    When the installation program appears, you are ready to begin the installation.

14.5.2 Navigating the OSB Installation Screens

Table 14-2 provides description of each installation program screen.

Table 14-2 OSB Installation Screens

Screen Description

Welcome

This screen introduces you to the product installer.

Auto Updates

Use this screen to automatically search My Oracle Support for available patches or automatically search a local directory for patches that you’ve already downloaded for your organization.

Installation Location

Use this screen to specify the location of your Oracle home directory.

If you plan to extend the existing SOA domain, then install the OSB software into the existing Oracle home, where the SOA software has already been installed.

If you plan to configure OSB in a separate domain, then install the OSB software in the Infrastructure Oracle home.

Installation Type

Use this screen to select the type of installation and consequently, the products and feature sets you want to install.

For this topology, select Service Bus.

Prerequisite Checks

This screen verifies that your system meets the minimum necessary requirements.

If there are any warning or error messages, you can refer to one of the following documents in Roadmap for Verifying Your System Environment in Oracle Fusion Middleware Installing and Configuring the Oracle Fusion Middleware Infrastructure.

Installation Progress

This screen allows you to see the progress of the installation.

Installation Complete

This screen appears when the installation is complete. Review the information on this screen, then click Finish to dismiss the installer.

14.5.3 Installing the Software on the Other Host Computers

If you have configured a separate shared storage volume or partition for SOAHOST2, then you must also install the software on SOAHOST2. For more information, see Shared Storage Recommendations When Installing and Configuring an Enterprise Deployment.

Note that the location where you install the Oracle home (which contains the software binaries) will vary, depending upon the host. To identify the proper location for you Oracle home directories, refer to the guidelines in File System and Directory Variables Used in This Guide.

14.5.4 Validating the OSB Installation

After you complete the installation, you can verify it by successfully completing the following tasks.

14.5.4.1 Reviewing the Installation Log Files

Review the contents of the installation log files to make sure that no problems were encountered. For a description of the log files and where to find them, see Understanding Installation Log Files in Oracle Fusion Middleware Installing Software with the Oracle Universal Installer.

14.5.4.2 Checking the Directory Structure

The contents of your installation vary based on the options you selected during the installation.

The addition of Oracle Service Bus adds the following directory and sub-directories:

ORACLE_HOME/osb/

bin
common
config
doc
financial
L10N
lib
osb
plugins
tools

For more information about the directory structure you should see after installation, see What are the Key Oracle Fusion Middleware Directories? in Oracle Fusion Middleware Understanding Oracle Fusion Middleware.

14.5.4.3 Viewing the Contents of Your Oracle Home

You can also view the contents of your Oracle home using the viewInventory script. For more information, see Viewing the contents of an Oracle home in Oracle Fusion Middleware Installing Software with the Oracle Universal Installer.

14.6 Extending the SOA or Infrastructure Domain to Include Oracle Service Bus

You can use the Configuration Wizard to extend the existing enterprise deployment SOA domain with the Oracle Service Bus. You have to perform a series of additional tasks to complete the extension.

Extending the domain involves the following tasks.

14.6.1 Starting the Configuration Wizard

Note:

If you added any customizations directly to the start scripts in the domain, those will be overwritten by the configuration wizard. To customize server startup parameters that apply to all servers in a domain, you can create a file called setUserOverrides.sh and configure it, for example, add custom libraries to the WebLogic Server classpath, specify additional java command line options for running the servers, or specify additional environment variables. Any customizations you add to this file are preserved during domain upgrade operations, and are carried over to remote servers when using the pack and unpack commands.

To begin domain configuration:

  1. Shut down the Administration Server to prevent any configuration locks, saves, or activations from occurring during the configuration of the domain.
  2. Navigate to the following directory and start the WebLogic Server Configuration Wizard. 
    ORACLE_HOME/oracle_common/common/bin
./config.sh -log=/tmp/debug_osb.txt -log_priority=FINEST

14.6.2 Navigating the Configuration Wizard Screens to Extend the Domain with Oracle Service Bus

In this step, you extend the domain created in Extending the Domain with Oracle SOA Suite , and add the Oracle Service Bus software components and Managed Servers.

The steps reflected in this section would be very similar if Oracle Service Bus was extending a domain containing only an Administration Server and a WSM-PM Cluster, but some of the options, libraries and components shown in the screens could vary.

Follow the instructions in these sections to create and configure the domain for the topology, with staticclusters.

14.6.2.1 Extending the Domain with Static Clusters

Follow the instructions in this section to create and configure the domain for the topology, with static clusters.

Note:

You can use the same procedure described in this section to extend an existing domain with static clusters. If your needs do not match the instructions given in the procedure, be sure to make your selections accordingly, or refer to the supporting documentation for additional details.

Domain creation and configuration includes the following tasks.

Task 1   Selecting the Domain Type and Domain Home Location

On the Configuration Type screen, select Update an existing domain.

In the Domain Location field, select the value of the ASERVER_HOME variable, which represents the complete path to the Administration Server domain home you created when you created in Creating the Initial Infrastructure Domain for an Enterprise Deployment.

For more information about the directory location variables, see File System and Directory Variables Used in This Guide

For more information about the other options on this screen, see Configuration Type in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 2   Selecting the Configuration Template

On the Templates screen, make sure Update Domain Using Product Templates is selected, then select the following templates:

  • Oracle Service Bus - 12.2.1.2.0[osb]

    The following additional templates should already be selected, because they were used to create the initial domain:

    • Oracle Enterprise Manager - 12.2.1.2.0[em]

    • Oracle WSM Policy Manager - 12.2.1.2.0[oracle_common]

    • Oracle JRF - 12.2.1.2.0[oracle_common]

    • WebLogic Coherence Cluster Extension - 12.2.1.2.0[wlserver]

For more information about the options on this screen, see Templates in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 3   Specifying the Database Configuration Type

On the Database Configuration Type screen, select RCU Data.

All fields are pre-populated, because you already configured the domain to reference the Fusion Middleware schemas that are required for the Infrastructure domain.

Verify and ensure that credentials in all the fields are the same that you have provided while configuring Oracle Fusion Middleware Infrastructure.

Click Get RCU Configuration after you finish verifying the database connection information. The following output in the Connection Result Log indicates that the operating succeeded:

Connecting to the database server...OK
Retrieving schema data from database server...OK
Binding local schema components with retrieved data...OK

Successfully Done.

Tip:

For more information about the RCU Data option, see Understanding the Service Table Schema in Oracle Fusion Middleware Creating Schemas with the Repository Creation Utility.

For more information about the other options on this screen, see Datasource Defaults in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 4   Specifying JDBC Component Schema Information

On the JDBC Component Schema screen, select OSB JMS Reporting Provider component schema.

When you select the schemas, the fields on the page are activated and the database connection fields are populated automatically.

Click Convert to GridLink and click Next.

Task 5   Providing the GridLink Oracle RAC Database Connection Details

On the GridLink Oracle RAC Component Schema screen, provide the information required to connect to the RAC database and component schemas, as shown in the following table.

Element Description and Recommended Value

SCAN, Host Name, and Port

Select the SCAN check box.

In the Host Name field, enter the Single Client Access Name (SCAN) Address for the Oracle RAC database.

In the Port field, enter the SCAN listening port for the database (for example, 1521)

ONS Host and Port

In the ONS Host field, enter the SCAN address for the Oracle RAC database.

In the Port field, enter the ONS Remote port (typically, 6200).

Enable Fan

Verify that the Enable Fan check box is selected, so the database can receive and process FAN events.
Task 6   Testing the JDBC Connections

Use the JDBC Component Schema Test screen to test the data source connections you have just configured.

A green check mark in the Status column indicates a successful test. If you encounter any issues, see the error message in the Connection Result Log section of the screen, fix the problem, then try to test the connection again.

For more information about the other options on this screen, see Test Component Schema in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 7   Selecting Advanced Configuration

To complete domain configuration for the topology, select the following options on the Advanced Configuration screen:

  • Topology

    Add, Delete, or Modify Settings for Server Templates, Managed Servers, Clusters, Virtual Targets, and Coherence.

  • File Store

Task 8   Configuring Managed Servers

On the Managed Servers screen, a new Managed Server for Oracle SOA Suite appears in the list of servers. This server was created automatically by the Oracle SOA Suite configuration template you selected in Task 2, "Selecting the Configuration Template".

Perform the following tasks to modify the default Oracle SOA Suite Managed Server and create a second Oracle SOA Suite Managed Server:

  1. Rename the default Oracle SOA Suite Managed Server to WLS_OSB1.

  2. Click Add to create a new Managed Server, and name it WLS_OSB2.

    Tip:

    The server names recommended here will be used throughout this document; if you choose different names, be sure to replace them as needed.

  3. Use the information in Table 14-3 to fill in the rest of the columns for each Managed Server.

  4. Select OSB-MGD-SVRS-ONLY as the server group for the OSB Servers. Deselect OSB-MGD-SVRS-COMBINED that is selected by default.

  5. Click Next.

For more information about the options on the Managed Server screen, see Managed Servers in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

The WLS_SOA Managed Servers will appear if you are extending an existing Oracle SOA Suite domain with Oracle Service Bus.

Task 9   Configuring a Cluster

In this task, you create a cluster of Managed Servers to which you can target the Oracle SOA Suite software.

You will also set the Frontend Host property for the cluster, which ensures that, when necessary, WebLogic Server will redirect Web services callbacks and other redirects to soa.example.com on the load balancer rather than the address in the HOST header of each request.

For more information about the soa.example.com virtual server address, see Configuring Virtual Hosts on the Hardware Load Balancer.

Use the Clusters screen to create a new cluster:

  1. Click the Add button.

  2. Specify OSB_Cluster in the Cluster Name field.

  3. Specify osb.example.com in the Frontend Host field.

  4. Specify 80 as the Frontend HTTP Port and 443 as the Frontend HTTPS port.

  5. From the Dynamic Server Groups drop-down list, select Unspecified.

Note:

By default, server instances in a cluster communicate with one another using unicast. If you want to change your cluster communications to use multicast, refer to Considerations for Choosing Unicast or Multicast in Oracle Fusion Middleware Administering Clusters for Oracle WebLogic Server.

For more information about the options on this screen, see Clusters in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Click Next.

For more information about the options on this screen, see Assign Servers to Clusters in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 13   Configuring Coherence Clusters

Use the Coherence Clusters screen to configure the Coherence cluster that is automatically added to the domain. Leave the port number value at 9991, as it was defined during the initial Infrastructure domain creation.

For Coherence licensing information, see Oracle Coherence Products in Oracle Fusion Middleware Licensing Information User Manual.

Task 14   Verifying the Existing Machines

Confirm that the following entries appear:

Name Node Manager Listen Address

SOAHOST1

SOAHOST1

SOAHOST2

SOAHOST2

ADMINHOST

ADMINVHN

Leave all other fields to their default values.

Click Next.

Task 15   Assigning Servers to Machines

On the Assign Servers to Machines screen, assign servers to machines as follows:

  • ADMINHOST:

    • AdminServer

  • SOAHOST1

    • WLS_SOA1 (if extending a SOA domain)

    • WLS_WSM1

    • WLS_OSB1

  • SOAHOST2:

    • WLS_SOA2 (if extending a SOA domain)

    • WLS_WSM2

    • WLS_OSB2

For more information about the options on this screen, see Assign Servers to Machines in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 16   Configuring Virtual Targets

Click Next to proceed to the next screen.

Task 17   Configuring Partitions

Click Next to proceed to the next screen.

Task 18   Configuring File Store

Configure the JMS File Stores that were just created during the configuration session (Wsee FileStore, UMS JMS FileStore, and FileStore).

On the JMS File Stores screen, assign the following directory for each of the OSB Persistence stores:

ORACLE_RUNTIME/domain_name/OSB_Cluster/jms

In this example, replace ORACLE_RUNTIME with the value of the variable for your environment. Replace OSB_Cluster with the name you assigned to the OSB cluster.

Ignore the JMS configuration warning that appears.

Note:

You do not need to customize the MDS file store locations. They are used only in development mode. In the production environments, MDS is persisted in the database.

Task 19   Reviewing Your Configuration Specifications and Configuring the Domain

The Configuration Summary screen contains the detailed configuration information for the domain you are about to create. Review the details of each item on the screen and verify that the information is correct.

You can go back to any previous screen if you need to make any changes, either by using the Back button or by selecting the screen in the navigation pane.

Domain creation will not begin until you click Update.

For more information about the options on this screen, see Configuration Summary in Oracle Fusion Middleware Creating WebLogic Domains Using the Configuration Wizard.

Task 20   Writing Down Your Domain Home and Administration Server URL

The Configuration Success screen will show the following items about the domain you just configured, including:

  • Domain Location

  • Administration Server URL

Make a note of both these items, because you will need them later; you will need the domain location to access the scripts used to start the Administration Server, and you will need the Administration Server URL to access the WebLogic Server Administration Console and Oracle Enterprise Manager Fusion Middleware Control.

Click Finish to dismiss the Configuration Wizard.

If the Admin Server was running during the domain extension process, restart the server before you continue.

Task 21   Start the Administration Server

Start the Administration Server to ensure the changes you have made to the domain have been applied.

14.7 Configuring a Default Persistence Store for Transaction Recovery

Oracle WebLogic Server uses the transaction logs to recover from system crashes or network failures.

Each Managed Server uses a transaction log that stores information about committed transactions that are coordinated by the server and that may not have been completed.

Oracle WebLogic Server uses this transaction log for recovery from system crashes or network failures. To leverage the migration capability of the Transaction Recovery Service for the Managed Servers within a cluster, store the transaction log in a location accessible to each Managed Server and its backup server.

Note:

To enable migration of the Transaction Recovery Service, specify a location on a persistent storage solution that is available to other servers in the cluster. All Managed Servers in the cluster must be able to access this directory. This directory must also exist before you restart the server.

The recommended location is a dual-ported SCSI disk or on a Storage Area Network (SAN). Note that it is important to set the appropriate replication and backup mechanisms at the storage level to guarantee protection in cases of a storage failure.

This information applies for file-based transaction logs. You can also configure a database-based persistent store for translation logs. For more information, see Using Persistent Stores for TLOGs and JMS in an Enterprise Deployment.

For instructions to configure a default persistence store with static clusters, see Configuring a Default Persistence Store for Transaction Recovery with a Static Cluster.

14.8 Propagating the Extended Domain to the Domain Directories and Machines

After you have extended the domain with the OSB instances, and you have restarted the Administration Server on SOAHOST1, you must then propagate the domain changes to the domain directories and machines.

Note that there is no need to propagate the updated domain to the WEBHOST1 and WEBHOST2 machines, because there are no changes to the Oracle HTTP Server instances on those host computers.

Refer to the following sections for more information.

14.8.1 Summary of the Tasks Required to Propagate the Changes to the Other Domain Directories and Machines

Table 14-4 summarizes the steps required to propagate the changes to all the domain directories and machines.

Table 14-4 Summary of Tasks Required to Propagate the Domain Chanegs to Domain Directories and Machines

Task Description More Information

Pack up the Extended Domain on SOAHOST1

Use the Pack command to create a new template jar file that contains the new OSB Servers configuration.

When you pack up the domain, create a template jar file called soadomaintemplateExtOSB.jar.

Packing Up the Extended Domain on SOAHOST1

Unpack the Domain in the Managed Servers Directory on SOAHOST1

Unpack the template jar file in the Managed Servers directory on SOAHOST1 local storage.

Unpack the Domain on SOAHOST2

Unpack the template jar file in the Managed Servers directory on the SOAHOST2 local storage.

Unpacking the Domain on SOAHOST2

14.8.2 Starting and Validating the WLS_OSB1 Managed Server

After extending the domain, restarting the Administration Server, and propagating the domain to the other hosts, use the following procedure to start the WLS_OSB1 server and validate that it is configured successfully:

14.8.2.1 Starting the WLS_OSB1 Managed Server

  1. Enter the following URL into a browser to display the Fusion Middleware Control login screen: 
    http://ADMINVHN:7001/em

    Note:

    If you have already configured Web tier, use http://admin.example.com/console.

  2. Log in to Fusion Middleware Control using the Administration Server credentials.
  3. In the Target Navigation pane, expand the domain to view the Managed Servers in the domain.
  4. Select only the WLS_OSB1 Managed Server and click Start Up on the Oracle WebLogic Server toolbar.

    Note:

    OSB Servers depend on the policy access service to be functional. This implies that the WSM-PM Managed Servers in the domain need to be up and running and reachable before the OSB servers are started.

  5. When the startup operation is complete, navigate to the Domain home page and verify that the WLS_OSB1 Managed Server is up and running.

14.8.2.2 Adding the MiddlewareAdministrators Role to the Enterprise Deployment Administration Group

Before you validate the Oracle Service Bus configuration on the WLS_OSB1 Managed Server, add the Oracle Service Bus MiddlewareAdministrators administration role to the enterprise deployment administration group (SOA Administrators) and add the IntegrationAdministrators group in the external LDAP directory.

To perform this task, refer to Configuring Roles for Administration of Oracle SOA Suite Products.

14.8.2.3 Validating the Managed Server by Logging in to the SOA Infrastructure

After you add the MiddlewareAdministrator role to the SOA Administrators group, you can then validate the configuration of the Oracle Service Bus software on the WLS_OSB1 Managed Server as follows.

  1. Use your Web browser to navigate to the following URL: 
    http://<OSB PORT NUMBER>/sbinspection.wsil

    Replace SOAHOST1 with the value of this variable in the Enterprise Deployment Workbook. For more information, see Physical and Virtual IP Addresses Required by the Enterprise Topology.

  2. Log in using the enterprise deployment administration user (SOA Administrators).

    With the default installation, this should result in the following HTTP response to the Web services call:

    <ins:inspection xmlns:ins="http://schemas.xmlsoap.org/ws/2001/10/inspection/"/>

14.8.3 Starting and Validating the WLS_OSB2 Managed Server

Follow similar steps as in the previous section for WLS_OSB2:

  1. Log in to Fusion Middleware Control using the Administration Server credentials.
  2. In the Target Navigation pane, expand the domain to view the Managed Servers in the domain.
  3. Select only the WLS_OSB2 Managed Server and click Start Up on the Oracle WebLogic Server tool bar.
  4. When the startup operation is complete, navigate to the Domain home page and verify that the WLS_OSB2 Managed Server is up and running. Access the equivalent URLs for the WLS_OSB2: 
    http://<OSB PORT NUMBER>/sbinspection.wsil
  5. Verify the correct deployment of the Oracle Service Bus console to the Administration Server by accessing the following URL: 
    http://ADMINVHN:7001/servicebus/

14.8.4 Validating the Location and Creation of the Transaction Logs

After the WLS_OSB1 and WLS_OSB2 Managed Servers are up and running, verify that the transaction log directory and transaction logs were created as expected, based on the steps you performed in Configuring a Default Persistence Store for Transaction Recovery:

ORACLE_RUNTIME/domain_name/OSB_Cluster/tlogs

  • _WLS_WLS_OSB1000000.DAT

  • _WLS_WLS_OSB2000000.DAT

14.8.5 Verifying the Appropriate Targeting for OSB Singleton Services

Oracle Service Bus uses some services that are singletons and that should run only in one of the WLS servers in the OSB_Cluster.

Verify that the appropriate targeting exists and that the following application is targeted only to WLS_OSB1:

  • Service Bus Domain Singleton Marker Application

To do this follow these steps:

  1. In a browser, go to the following URL: 
    http://ADMINVHN:7001/console

    Note:

    If you have already configured Web tier, use http://admin.example.com/console.

  2. Log in as the administrator.
  3. In the Domain Structure tree on the left, click Deployments.
  4. Find the Service Bus Domain Singleton Marker Application. Verify that in the Targets column in the table only WLS_OSB1 appears as target.

14.9 Configuring the Web Tier for the Extended Domain

It is important to understand how to configure the Web server instances on the Web tier so that they route requests for both public and internal URLs to the proper clusters in the extended domain.

Note:

If you add custom endpoints in OSB, make sure that you add the appropriate URLs to the OHS or the OTD configuration. For example, if you add a proxy service such as RNOWOSB/, you must add the following URL to osb_vh.conf for the services to be available through OHS/OTD: 
<Location /RNOWOSB>
   WLSRequest ON
        WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
        WLProxySSL ON
        WLProxySSLPassThrough ON
</Location>
Alternatively, Oracle recommends creating a unique root context in the Web tier and use that as the base path for all proxy services. For example, if the root context is /endpoint, the configured endpoint URL will be osb.example.com/endpoint/RNOWOSB/. This avoids the need to alter the Web tier config file with every new endpoint and also benefits from a single resource configuration for SSO, if OAM is used.

14.9.1 Configuring Oracle Traffic Director for the Extended Domain

If you have configured Oracle Traffic Director for this domain, you might be required to add additional origin server pools, virtual servers, or routes to the Oracle Traffic Director configuration. To understand the Oracle Traffic Director requirements for each Oracle Fusion Middleware product and for instructions on adding origin server pools, virtual servers, and routes, see Defining Oracle Traffic Director Virtual Servers for an Enterprise Deployment.

14.9.2 Configuring Oracle HTTP Server for the Oracle Service Bus

To configure the Oracle HTTP Server instances in the Web tier so they route requests correctly to the Oracle Service Bus cluster, use the following procedure to create an additional Oracle HTTP Server configuration file that creates and defines the parameters of the soa.example.com virtual server.

This procedure assumes you have performed the Oracle HTTP Server configuration tasks described in Configuring Oracle HTTP Server for Administration and Oracle Web Services Manager.

To set the parameter:

  1. Log in to WEBHOST1 and change directory to the configuration directory for the first Oracle HTTP Server instance (ohs1): 
    cd OHS_DOMAIN_HOME/config/fmwconfig/components/OHS/ohs1/moduleconf
  2. Create a new configuration file, called osb_vh.conf file, and add the following <VirtualHost> directive to the file: 
    <VirtualHost WEBHOST1:7777>
    ServerName https://osb.example.com:443
    ServerAdmin you@your.address
    RewriteEngine On
    RewriteOptions inherit
</VirtualHost>
  3. Add the following directives inside the <VirtualHost> tags: 
    <Location /sbinspection.wsil>
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /sbresource>
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /osb>
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /alsb>
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /default>
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

    The osb_vh.conf file will appear as it does in Example 14-1.

  4. Add the following entry to the admin_vh.conf file within the <VirtualHost> tags: 
    <Location /sbconsole >
  WLSRequest ON
  WebLogicHost ADMINVHN
  WeblogicPort 7001
</Location>

<Location /servicebus>
  WLSRequest ON
  WebLogicHost ADMINVHN
  WeblogicPort 7001
</Location>

<Location /lwpfconsole >
  WLSRequest ON
  WebLogicHost ADMINVHN
  WeblogicPort 7001
</Location>

    The admin_vh.conf file will appear as it does in Example 14-2.

  5. Copy the osb_vh.conf file and the admin_vh.conf file to the configuration directory for the second Oracle HTTP Server instance (ohs2) on WEBHOST2: 
    OHS_DOMAIN_HOME/config/fmwconfig/components/OHS/ohs2/moduleconf
  6. Edit the osb_vh.conf file and change any references to WEBHOST1 to WEBHOST2 in the <VirtualHost> directives.
  7. Restart Oracle HTTP Servers on WEBHOST1 and WEBHOST2.

Example 14-1 osb_vh.conf file

<VirtualHost WEBHOST1:7777>
  ServerName https://osb.example.com:443
  ServerAdmin you@your.address
  RewriteEngine On
  RewriteOptions inherit

<Location /sbinspection.wsil >
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /sbresource >
  WLSRequest ON
  WebLogicCluster SOAHOST1:8011,SOAHOST2:8011
  WLProxySSL ON
  WLProxySSLPassThrough ON
</Location>

<Location /osb >

</VirtualHost>

14.9.3 Configuring the WebLogic Proxy Plug-In

Set the WebLogic Plug-In Enabled parameter for the OSB cluster.

  1. Log in to the Oracle WebLogic Server Administration Console.
  2. In the Domain Structure pane, expand the Environment node.
  3. Click on Clusters.
  4. Select the OSB_Cluster cluster to which you want to proxy requests from Oracle HTTP Server.

    The Configuration: General tab is displayed.

  5. Scroll down to the Advanced section and expand it.
  6. Click Lock and Edit.
  7. Set the WebLogic Plug-In Enabled to yes.
  8. Click Save and Activate the changes.Restart the OSB servers for the changes to be effective.

14.9.4 Validating the Oracle Service Bus URLs Through the Load Balancer

Verify the Oracle Service Bus URLs to ensure that appropriate routing and failover is working from the hardware load balancer to the HTTP Server instances to the Oracle Service Bus components.

To verify the URLs:

  1. While WLS_OSB1 is running, stop WLS_OSB2 using the Oracle WebLogic Server Administration Console.
  2. Access the following URL and verify the HTTP response as indicated in Starting and Validating the WLS_OSB2 Managed Server: 
    https://osb.example.com/
  3. Start WLS_OSB2 from the Oracle WebLogic Server Administration Console.
  4. Stop WLS_OSB1 from the Oracle WebLogic Server Administration Console.
  5. Access the same URL and verify the HTTP response as indicated in section Starting and Validating the WLS_OSB2 Managed Server.

    Note:

    Since a front end URL has been set for the OSB_Cluster, the requests to the urls result in a re-route to the LBR, but in all cases it should suffice to verify the appropriate mount points and correct failover in Oracle HTTP Server.

  6. Verify this URL using your load balancer address: 
    https://osb.example.com:443/sbinspection.wsil

    You can also verify http://admin.example.com:80/servicebus.

14.10 Post-Configuration Tasks for Oracle Service Bus

After you install and configure Oracle Service Bus in the domain, consider the following post-configuration tasks.

14.10.1 Enabling High Availability for Oracle DB, File and FTP Adapters

Oracle SOA Suite and Oracle Service Bus use the same database, File, and FTP JCA adapters.

You create the required database schemas for these adapters when you use the Oracle Repository Creation Utility before configuring Oracle SOA Suite. The database adapter does not require any configuration at the WebLogic Server resource level.

The required configuration for the other adapters is described in section Enabling High Availability for Oracle File and FTP Adapters.

If you are configuring Oracle Service Bus as an extension of a SOA domain, you do not need to add to the configuration already performed for the adapters.

If you are deploying Oracle Service Bus as an extension to an Oracle Fusion Middleware Infrastructure domain (without Oracle SOA Suite), then you must do the following:

14.10.2 Considerations for Poller Transports

OSB provides native Poller transports that are not transactional in nature. These transports poll a source directory or email server for new messages and push the processing payloads to the required JMS destinations. Email, File, FTP, and SFTP fall in this category.

Poll-based transports use a transport poller thread that is pinned to a Managed Server. All Managed Servers in a cluster can process the pertaining payload, but only one server can poll for the message. To protect the system from outages, the poller thread must be configured as an application-scoped singleton and the involved JMS destinations must be highly available.

To configure the transports as application-scoped singletons:

  1. Log in to Oracle Fusion Middleware Enterprise Manager.

  2. Navigate to SOA > service-bus > Global Settings and select Automatic Singleton Service Migration.

To protect the pertaining JMS destinations from failures, you can use different alternatives:

  • When you use Weblogic static clusters, configure Automatic Service Migration (ASM) for the OSB migratable targets. In the case of a failure, the affected JMS and JTA services are migrated automatically to another member of the cluster.

  • Alternatively, configure Whole Server Migration for the OSB cluster. In this case, the entire WLS server, including its JMS and JTA services, are restarted in another node.

14.10.3 Configuring Specific Oracle Service Bus Services for an Enterprise Deployment

To use IBM WebSphere MQ Connection resources and the MQ Transport in Oracle Service Bus, you must add the MQ client libraries to the classpath.

One option is to copy the required MQ libraries to the following location in the domain home directory:

DOMAIN_HOME/lib

This is also the case for custom assertions and JBoss integration services:

  • When using JBoss initial context factory classes, make sure to include the class and any dependent classes in the DOMAIN_HOME/lib directory.

  • Similarly, for custom assertions, create the required jar file with the assertion and add the jar to the DOMAIN_HOME/lib directory.

Further, to use these services in an enterprise deployment, you must add the required libraries to the Administration Server domain home (ASERVER_HOME/lib) and the Managed Server domain home (MSERVER_HOME/lib).

For more information about configuring and developing services for Oracle Service Bus, see Getting Started with the Oracle Service Bus Console in Oracle Fusion Middleware Developing Services with Oracle Service Bus.

14.10.4 Enabling SSL Communication Between the Oracle Service Bus Servers and the Hardware Load Balancer

After you extend the domain with Oracle Service Bus, you should also ensure that the Administration Server and Managed Servers can access the front-end, SSL URL of the hardware load balancer.

This will allow Oracle Service Bus Web services and other services to invoke callbacks and other communications with the front-end, secure URL.

For more information, see Enabling SSL Communication Between the Middle Tier and the Hardware Load Balancer.

14.10.5 Backing Up the Oracle Service Bus Configuration

It is an Oracle best practices recommendation to create a backup after successfully extending a domain or at another logical point. Create a backup after verifying that the installation so far is successful. This is a quick backup for the express purpose of immediate restoration in case of problems in later steps.

The backup destination is the local disk. You can discard this backup when the enterprise deployment setup is complete. After the enterprise deployment setup is complete, you can initiate the regular deployment-specific Backup and Recovery process.

For information about backing up your configuration, see Performing Backups and Recoveries in the SOA Enterprise Deployments.

14.11 Enabling Automatic Service Migration and JDBC Persistent Stores for Oracle Service Bus

To ensure that Oracle Service Bus is configured for high availability, configure the Oracle Service Bus Managed Servers for automatic service migration for failover and zero data loss.

For more information on enabling server migration, see Configuring Automatic Service Migration in an Enterprise Deployment.

For additional high availability, you can also configure your transaction logs store and JMS store in a database. For more information, see Using Persistent Stores for TLOGs and JMS in an Enterprise Deployment.
