13 Extending the Domain with Oracle SOA Suite

You need to perform certain tasks in order to extend the enterprise deployment domain with the Oracle SOA Suite software.

Parent topic: Configuring the Enterprise Deployment

13.1 Variables Used When Configuring Oracle SOA Suite

While extending the domain with Oracle SOA Suite, 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

  • APPLICATION_HOME

  • DEPLOY_PLAN_HOME

  • OHS_DOMAIN_HOME

  • JAVA_HOME

  • ORACLE_RUNTIME

In addition, you'll be referencing the following virtual IP (VIP) address defined in Reserving the Required IP Addresses for an Enterprise Deployment:

  • ADMINVHN

Actions in this chapter will be performed on the following host computers:

  • SOAHOST1

  • SOAHOST2

  • WEBHOST1

  • WEBHOST2

13.2 Synchronizing the System Clocks

Before you extend the domain to include Oracle SOA Suite, verify that the system clocks on each host computer are synchronized. You can do this by running the date command simultaneously on all the hosts in each cluster.

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

13.3 Installing the Software for an Enterprise Deployment

The procedure for installing the software for an enterprise deployment is explained in this section.

13.3.1 Starting the Oracle SOA Suite Installer on SOAHOST1

To start the installation program:

  1. Log in to SOAHOST1.
  2. Go to the directory where you downloaded the installation program.
  3. Launch the installation program by invoking the java executable from the JDK directory on your system, as shown in the example below. 
    JAVA_HOME/bin/java -d64 -jar Installer File Name

    Be sure to replace the JDK location in these examples with the actual JDK location on your system.

    Replace Installer File Name with the name of the actual installer file for your product listed in Identifying and Obtaining Software Distributions for an Enterprise Deployment.

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

13.3.2 Navigating the Installation Screens

The installation program displays a series of screens, in the order listed in the following table.

If you need additional help with any of the installation screens, click the screen name.

13.3.3 Installing Oracle SOA Suite on the Other Host Computers

If you have configured a separate shared storage volume or partition for the products mount point and ORACLE_HOME on SOAHOST2, then you must also perform the product installation on SOAHOST2.

For more information, see Shared Storage Recommendations When Installing and Configuring an Enterprise Deployment.

To install the software on the other host computers in the topology, log in to each host, and use the instructions in Starting the Infrastructure Installer on SOAHOST1 and Navigating the Infrastructure Installation Screens to create the Oracle home on the appropriate storage device.

Note:

In previous releases, the recommended enterprise topology included a colocated set of Oracle HTTP Server instances. In those releases, there was a requirement to install the Infrastructure on the Web Tier hosts (WEBHOST1 and WEBHOST2). However, for this release, the enterprise deployment topology assumes the Web servers are installed and configured in standalone mode, so they are not considered part of the application tier domain. For more information, see Configuring Oracle HTTP Server for an Enterprise Deployment

13.3.4 Verifying the Installation

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

13.3.4.1 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.

13.3.4.2 Checking the Directory Structure

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

The addition of Oracle SOA Suite adds the following directory and sub-directories:

/u01/oracle/products/fmw/soa

bam
bin
bpm
common
integration
jlib
plugins
readme.txt
reports
soa

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

13.3.4.3 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 Installing Software with the Oracle Universal Installer.

13.4 Creating the Oracle SOA Suite Database Schemas

Before you can configure an Oracle SOA Suite domain, you must install the required schemas in a certified database for use with this release of Oracle Fusion Middleware.

13.4.1 Starting the Repository Creation Utility (RCU)

To start the Repository Creation Utility (RCU):

  1. Navigate to the ORACLE_HOME/oracle_common/bin directory on your system.
  2. Make sure the JAVA_HOME environment variable is set to the location of a certified JDK on your system. The location should be up to but not including the bin directory. For example, if your JDK is located in /u01/oracle/products/jdk:

    On UNIX operating systems:

    export JAVA_HOME=/u01/oracle/products/jdk
  3. Start RCU:

    On UNIX operating systems:

    ./rcu

    Note:

    If your database has Transparent Data Encryption (TDE) enabled, and you want to encrypt your tablespaces created by the RCU, provide the -encryptTablespace true option when you start the RCU.

    This will default the appropriate RCU GUI Encrypt Tablespace checkbox selection on the Map Tablespaces screen without further effort during the RCU execution. For more information, see olink:RCUUG-GUID-D4AE68B4-11DF-459B-A5F1-D4DAAA3B7233 in Oracle Fusion Middleware Creating Schemas with the Repository Creation Utility.

13.4.2 Navigating the RCU Screens to Create the Schemas

Schema creation involves the following tasks:

Task 1   Introducing RCU

Click Next.

Task 2   Selecting a Method of Schema Creation

If you have the necessary permission and privileges to perform DBA activities on your database, select System Load and Product Load. This procedure assumes that you have the necessary privileges.

If you do not have the necessary permission or privileges to perform DBA activities in the database, you must select Prepare Scripts for System Load on this screen. This option will generate a SQL script, which can be provided to your database administrator to create the required schema. See Understanding System Load and Product Load in Creating Schemas with the Repository Creation Utility.

Task 3   Providing Database Connection Details

Provide the database connection details for RCU to connect to your database.

In the Host Name field, enter the SCAN address of the Oracle RAC Database.

Enter the DBMS/Service details.

Enter the Schema Owner and Schema Password details.

Click Next to proceed, then click OK on the dialog window confirming that connection to the database was successful.

Task 4   Specifying a Custom Prefix and Selecting Schemas

Choose Select existing prefix, and then select the prefix you used when you created the initial domain.

From the list of schemas, select the SOA Suite schema. This will automatically select SOA Infrastructure. In addition, the following dependent schemas have already been installed with the Infrastructure and are grayed out:

  • Common infrastructure Services

  • User Messaging Service

  • Metadata Services

  • Weblogic Services

  • Oracle Platform Security Services

  • Audit Services

  • Audit Services Append

  • Audit Services Viewer

The custom prefix is used to logically group these schemas together for use in this domain only; you must create a unique set of schemas for each domain as schema sharing across domains is not supported.

Tip:

For more information about custom prefixes, see Understanding Custom Prefixes in Creating Schemas with the Repository Creation Utility.

For more information about how to organize your schemas in a multi-domain environment, see Planning Your Schema Creation in Creating Schemas with the Repository Creation Utility.

Click Next to proceed, then click OK on the dialog window confirming that prerequisite checking for schema creation was successful.

Task 5   Specifying Schema Passwords

Specify how you want to set the schema passwords on your database, then specify and confirm your passwords.

Tip:

You must make a note of the passwords you set on this screen; you will need them later on during the domain creation process.

Task 6   Specifying Custom Variables

Specify the custom variables for the SOA Infrastructure schema.

For the enterprise deployment topology, enter LARGE for the Database Profile custom variable; if you are planning on using Oracle Healthcare, then enter YES for the Healthcare Integration variable.

For more information, see About the Custom Variables Required for the SOA Suite Schemas in Installing and Configuring Oracle SOA Suite and Business Process Management.

Task 7   Verifying the Tablespaces for the Required Schemas

On the Map Tablespaces screen, review the information, and then click Next to accept the default values.

Click OK in the confirmation dialog box.

Task 8   Completing Schema Creation

Navigate through the remainder of the RCU screens to complete schema creation. When you reach the Completion Summary screen, click Close to dismiss RCU.

Task 9   Verifying the Schema Creation

To verify that the schemas were created successfully, and to verify the database connection details, use SQL*Plus or another utility to connect to the database, using the SOAINFRA schema name and the password you provided.

For example:

./sqlplus

SQL*Plus: Release 12.1.0.2.0 Production on Wed Aug 31 05:41:31 2016

Copyright (c) 1982, 2014, Oracle.  All rights reserved.

Enter user-name: FMW1221_SOAINFRA
Enter password: soainfra_password

Connected to:
Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production 
With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP, Advanced Analytics and Real Application Testing options 

SQL>

13.4.3 Configuring SOA Schemas for Transactional Recovery

After you have installed the Oracle SOA Suite schemas successfully, use the procedure in this section to configure the schemas for transactional recovery.

This procedure sets the appropriate database privileges so that the Oracle WebLogic Server transaction manager can query the schemas for transaction state information and issue the appropriate commands, such as commit and rollback, during recovery of in-flight transactions after a WebLogic Server is unexpectedly unavailable.

These privileges should be granted to the owner of the SOAINFRA schema, which you defined when you created the schemas with the Repository Creation Utility.

To configure the SOA schemas for transactional recovery privileges:

  1. Log on to SQL*Plus as a user with sysdba privileges. For example: 
    sqlplus "/ as sysdba"
  2. Enter the following commands: 
    SQL> Grant select on sys.dba_pending_transactions to soa_schema_prefix_soainfra;

Grant succeeded.
 
SQL> Grant force any transaction to soa_schema_prefix_soainfra;
 
Grant succeeded.
 
SQL>

13.5 Extending the Enterprise Deployment Domain with Oracle SOA Suite

Perform the following tasks for extending the existing enterprise deployment domain with the Oracle SOA Suite software.

Note:

For an improved footprint and to optimize startup, only core adapters are targeted to the SOA cluster (MFT Cluster if you are configuring MFT) after the Configuration Wizard session. You must target the following second-tier adapters manually, if needed:

  • MSMQAdapter

  • SocketAdapter

  • OracleBamAdapter

  • CoherenceAdapter

  • SAPAdapter

  • SiebelAdapter

  • ERPAdapter

  • Oracle SalesCloudAdapter

  • RightNowAdapter

  • EloquaAdapter

  • NetSuiteAdapter

For instructions for targeting adapters manually, see Targeting Adapters Manually.

Extending the domain involves the following tasks.

13.5.1 Starting the Configuration Wizard

To start the Configuration Wizard:

  1. From the WebLogic Server Console, stop any managed servers that will be modified by this domain extension. Managed Servers that are not effected can remain on-line.
  2. For any managed servers to be modified, verify the managed server shutdown has completed.
  3. Stop the Administration Server once all managed servers are in a steady state.
  4. Navigate to the following directory and start the WebLogic Server Configuration Wizard. 
    cd ORACLE_HOME/oracle_common/common/bin
./config.sh -log=debug_soa.log -log_priority=FINEST

13.5.2 Navigating the Configuration Wizard Screens to Extend the Domain with Oracle SOA Suite

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

13.5.2.1 Extending the Domain with Static Clusters

Task 10   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 SOA_Cluster in the Cluster Name field.

  3. Specify soa.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.

Task 11   Assigning Server Templates

Click Next to continue.

Task 12   Configuring Dynamic Servers
Verify that all dynamic server options are disabled for clusters that are to remain as static clusters.

  1. Confirm that the Dynamic Cluster, Calculated Listen Port, and Calculated Machine Names checkboxes on this screen are unchecked.

  2. Confirm the Server Template selection is Unspecified.

  3. Click Next.

Task 13   Assigning Managed Servers to the Cluster

Use the Assign Servers to Clusters screen to assign WLS_SOA1 and WLS_SOA2 to the new cluster SOA_Cluster:

  1. In the Clusters pane, select the cluster to which you want to assign the servers; in this case, SOA_Cluster.

  2. In the Servers pane, assign WLS_SOA1 to SOA_Cluster by doing one of the following:

    • Click WLS_SOA1 Managed Server once to select it, and then click on the right arrow to move it beneath the selected cluster in the Clusters pane.

    • Double-click WLS_SOA1 to move it beneath the selected cluster in the clusters pane.

  3. Repeat to assign WLS_SOA2 to SOA_Cluster.

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 14   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 15   Verifying the Existing Machines

Click Next to proceed.

Task 16   Assigning Servers to Machines

Use the Assign Servers to Machines screen to assign the Oracle SOA Suite Managed Servers you just created to the corresponding machines in the domain.

Assign WLS_SOA1 to SOAHOST1, and assign WLS_SOA2 to SOAHOST2.

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 17   Configuring Virtual Targets

Click Next.

Task 18   Configuring Partitions

Click Next.

Task 19   Configuring File Store

In the JMS File Stores screen, assign the following directory for each of the SOA Persistence stores, including UMS and BPM file stores:

ORACLE_RUNTIME/domain_name/SOA_Cluster/jms

Note:

  • Create the jms folder before starting the managed servers.

  • 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.

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

Task 20   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.

Click Update to execute the domain extension.

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

Task 21   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 22   Start the Administration Server

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

13.5.3 Targeting Adapters Manually

Only core adapters are targeted to the SOA cluster after you run the Configuration Wizard. You must target second-tier adapters manually, on a need basis.

To target a second-tier adapter manually:

  1. Navigate to and log into the Oracle WebLogic Server Administration Console. For example: http://ADMINVHN:7001/console.

    Note:

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

  2. In the left pane of the console, click Deployments.
  3. Locate and click the name of the adapter in the Summary of the Deployments table.
  4. Click Lock & Edit.
  5. In the Targets tab, select SOA_Cluster.

    Note:

    If you are deploying MFT, select MFT_Cluster as the target.

  6. Click Save.
  7. Activate the changes.
  8. In the left pane of the console, click Deployments and verify that the adapter is in the Active state.

13.6 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.

13.6.1 Configuring a Default Persistence Store for Transaction Recovery with a Static Cluster

To set the location for the default persistence stores for each managed server in a static cluster, complete the following steps:

  1. Log into the Oracle WebLogic Server Administration Console:

    ADMINVHN:7001/console

    Note:

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

  2. In the Change Center section, click Lock & Edit.

  3. For each of the Managed Servers in the cluster:

    1. In the Domain Structure window, expand the Environment node, and then click the Servers node.

      The Summary of Servers page appears.

    2. Click the name of the server (represented as a hyperlink) in the Name column of the table.

      The settings page for the selected server appears and defaults to the Configuration tab.

    3. On the Configuration tab, click the Services tab.

    4. In the Default Store section of the page, enter the path to the folder where the default persistent stores will store its data files.

      For the enterprise deployment, use the ORACLE_RUNTIME directory location. This subdirectory serves as the central, shared location for transaction logs for the cluster. For more information, see File System and Directory Variables Used in This Guide.

      For example:

      ORACLE_RUNTIME/domain_name/cluster_name/tlogs

      In this example, replace ORACLE_RUNTIME with the value of the variable for your environment. Replace domain_name with the name you assigned to the domain. Replace cluster_name with the name of the cluster you just created.

    5. Click Save.

  4. Complete step 3 for all servers in the SOA_Cluster.

    Note:

    If you are configuring a default persistence store for ESS, BAM, or OSB, use ESS_Cluster, BAM_Cluster, and OSB_Cluster respectively, instead of SOA_Cluster.

  5. Click Activate Changes.

Note:

You will validate the location and the creation of the transaction logs later in the configuration procedure.

13.7 Propagating the Extended Domain to the Domain Directories and Machines

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

Table 13-1 summarizes the steps required to propagate the changes to all 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.

Table 13-1 Summary of Tasks Required to Propagate the Domain Changes 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 Oracle SOA Suite Managed Servers configuration.

When you pack up the domain, create a template JAR file called soadomaintemplate.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.

Unpacking the Domain in the Managed Servers Domain Directory on SOAHOST1

Unpack the Domain on SOAHOST2

Unpack the template JAR file in the Managed Servers directory on the SOAHOST2local storage.

  

13.7.1 Packing Up the Extended Domain on SOAHOST1

Use the following steps to create a template JAR file that contains the domain configuration information:

  1. Log in to SOAHOST1 and run the pack command to create a template JAR file as follows: 
    cd ORACLE_COMMON_HOME/common/bin
 
./pack.sh -managed=true 
          -domain=ASERVER_HOME 
          -template=full_path/soadomaintemplate.jar
          -template_name=soa_domain_template
          -log=/tmp/pack_soa.log
          -log_priority=debug

    In this example:

    • Replace ASERVER_HOME with the actual path to the domain directory you created on the shared storage device.

    • Replace full_path with the complete path to the directory where you want the template jar file saved.

    • soadomaintemplate.jar is a sample name for the JAR file you are creating, which will contain the domain configuration files, including the configuration files for the Oracle HTTP Server instances.

    • soa_domain_template is the name assigned to the domain template file.

  2. Make a note of the location of the template JAR file you just created with the pack command.

    Tip:

    For more information about the pack and unpack commands, see Overview of the Pack and Unpack Commands in Oracle Fusion Middleware Creating Templates and Domains Using the Pack and Unpack Commands.

13.7.2 Unpacking the Domain in the Managed Servers Domain Directory on SOAHOST1

To copy the updated domain configuration information from the Administration Server domain directory to the Managed Servers domain directory:

  1. Log in to SOAHOST1 if you haven't already.
  2. If you haven't already, create the recommended directory structure for the Managed Server domain on the SOAHOST1 local storage device.
  3. Run the unpack command to unpack the template in the domain directory onto the local storage, as follows: 
    cd ORACLE_COMMON_HOME/common/bin

./unpack.sh -domain=MSERVER_HOME  \
    -template=full_path/soadomaintemplate.jar \
    -overwrite_domain=true \
    -app_dir=APPLICATION_HOME

    In this example:

    • Replace MSERVER_HOME with the complete path to the domain home to be created on the local storage disk. This is the location where the copy of the domain will be unpacked.

    • soadomaintemplate.jaris the directory path and name of the template you created when you ran the pack command to pack up the domain on the shared storage device.

    • The -overwrite_domain=true argument is necessary when you are unpacking a Managed Server template into an existing domain and existing applications directories.

      For any file that is overwritten, a backup copy of the original is created. If any modifications have been applied to the start scripts and EAR files in the Managed Server domain directory, they must be restored after this unpack operation.

    • Replace APPLICATION_HOME with the complete path to the applications directory for the domain on shared storage.

    Tip:

    For more information about the pack and unpack commands, see Overview of the Pack and Unpack Commands in Creating Templates and Domains Using the Pack and Unpack Commands.

  4. Change directory to the newly created MSERVER_HOME directory and verify that the domain configuration files were copied to the correct location on the SOAHOST1 local storage device.

13.7.3 Unpacking the Domain on SOAHOST2

This procedure assumes you have copied the file that you created earlier in a location that is accessible from both SOAHOST1 and SOAHOST2; such as the ASERVER_HOME directory, which is located on the shared storage filer:

  1. Log in to SOAHOST2.
  2. If you haven't already, create the recommended directory structure for the Managed Server domain on the SOAHOST2 storage device.
  3. Make sure the soadomaintemplate.jar accessible to SOAHOST2.
    For example, if you are using a separate shared storage volume or partition for SOAHOST2, then copy the template to the volume or partition mounted to SOAHOST2.
  4. Run the unpack command to unpack the template in the domain directory onto the local storage, as follows: 
    cd ORACLE_COMMON_HOME/common/bin

./unpack.sh -domain=MSERVER_HOME
            -overwrite_domain=true
            -template=complete_path/soadomaintemplate.jar 
            -log_priority=DEBUG
            -log=/tmp/unpack.log
            -app_dir=APPLICATION_HOME

    Note:

    The -overwrite_domain option in the unpack command allows unpacking a managed server template into an existing domain and existing applications directories. For any file that is overwritten, a backup copy of the original is created. If any modifications had been applied to the start scripts and ear files in the managed server domain directory, they must be restored after this unpack operation.

    Additionally, to customize server startup parameters that apply to all servers in a domain, you can create a file called setUserOverrides.sh and configure it to, 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.

    In this example:

    • Replace MSERVER_HOME with the complete path to the domain home to be created on the local storage disk. This is the location where the copy of the domain will be unpacked.

    • Replace complete_path/soadomaintemplate.jar with the complete path and file name of the domain template jar file that you created when you ran the pack command to pack up the domain on the shared storage device.

    • Replace APPLICATION_HOME with the complete path to the Application directory for the domain on shared storage. For more information, see File System and Directory Variables Used in This Guide.

    Tip:

    For more information about the pack and unpack commands, see Overview of the Pack and Unpack Commands in Oracle Fusion Middleware Creating Templates and Domains Using the Pack and Unpack Commands.

  5. Change directory to the newly created MSERVER_HOME directory and verify that the domain configuration files were copied to the correct location on the SOAHOST2 local storage device.

13.8 Starting and Validating the WLS_SOA1 Managed Server

Now that you have extended the domain, started the Administration Server, and propagated the domain to the other hosts, you can start the newly configured Oracle SOA Suite Managed Servers.

This process involves three tasks as described in the following sections.

13.8.1 Starting the WLS_SOA1 Managed Server

To start the WLS_SOA1 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_SOA1 Managed Server and click Start Up on the Oracle WebLogic Server toolbar.

    Note:

    SOA 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 SOA servers are started.

  5. When the startup operation is complete, navigate to the Domain home page and verify that the WLS_SOA1 Managed Server is up and running.

13.8.2 Adding the SOAAdmin Role to the Administrators Group

Before you validate the Oracle SOA Suite configuration on the WLS_SOA1 Managed Server, add the SOAAdmin administration role to the enterprise deployment administration group (SOA Administrators).

To perform this task, refer to Configuring Roles for Administration of an Enterprise Deployment.

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

After you add the SOAAdmin role to the SOA Administrators group, you can then validate the configuration of the Oracle SOA Suite software on the WLS_SOA1 Managed Server as follows:

  1. Use your Web browser to navigate to the following URL: 
    http://SOAHOST1:8001/soa-infra/
  2. Log in using the enterprise deployment administrator user credentials (weblogic_soa).

    You should see a web page with the following title:

    "Welcome to the Oracle SOA Platform on WebLogic"

13.9 Starting and Validating the WLS_SOA2 Managed Server

After validating the successful configuration and startup of the WLS_SOA1 Managed Server, you can start and validate the WLS_SOA2 Managed Server.

To start and validate the WLS_SOA2 Managed Server, use the procedure in Starting and Validating the WLS_SOA1 Managed Serverfor WLS_SOA2 Managed Server.

For the validation URL, enter the following URL in your web browser and log in using the enterprise deployment administrator user (weblogic_soa):

http://SOAHOST2:8001/soa-infra/

13.10 Validating the Location and Creation of the Transaction Logs

After WLS_SOA1 and WLS_SOA2 are up and running, verify that the transaction log directory and transaction logs were created as expected.

Run the following command to verify, based on the steps you performed in Configuring a Default Persistence Store for Transaction Recovery:

ls -al ORACLE_RUNTIME/domain_name/cluster_name/tlogs

  • _WLS_WLS_SOA1000000.DAT

  • _WLS_WLS_SOA2000000.DAT

13.11 Configuring the Web Tier for the Extended Domain

Configure the Web server instances on the Web tier so that the instances route requests for both public and internal URLs to the proper clusters in the extended domain.

For additional steps in preparation for possible scale-out scenarios, see Updating Cross Component Wiring Information.

13.11.1 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.

13.11.2 Configuring Oracle HTTP Server for the WLS_SOA Managed Servers

To configure the Oracle HTTP Server instances in the Web tier so they route requests correctly to the Oracle SOA Suite 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 performed the Oracle HTTP Server configuration tasks described in Configuring Oracle HTTP Server to Route Requests to the Application Tier.

To create the virtual host configuration file so requests are routed properly to the Oracle SOA Suite clusters:

  1. Log in to WEBHOST1 and change directory to the configuration directory for the first Oracle HTTP Server instance (OHS_1): 
    cd OHS_DOMAIN_HOME/config/fmwconfig/components/OHS/ohs1/moduleconf/
  2. Create the soa_vh.conf file and add the following directive: 
    <VirtualHost WEBHOST1:7777>
    ServerName https://soa.example.com:443
    ServerAdmin you@your.address
    RewriteEngine On
    RewriteOptions inherit
</VirtualHost>
  3. Add the following directives inside the <VirtualHost> tags:

    Note:

    The URL entry for /workflow is optional. It is for workflow tasks associated with Oracle ADF task forms. The /workflow URL itself can be a different value, depending on the form.

    <Location /soa-infra>

    The soa_vh.conf file will appear as it does in Example 13-1.

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

Example 13-1 soa_vh.conf file

Note:

If internal invocations are going to be used in the system, add the appropriate locations to the soainternal virtual host.

13.11.3 Configuring the WebLogic Proxy Plug-In

Before you can validate that requests are routed correctly through the Oracle HTTP Server instances, you must set the WebLogic Plug-In Enabled parameter for the clusters you just configured.

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

    The Configuration: General tab is displayed.

  6. Scroll down to the Advanced section and expand it.
  7. Set WebLogic Plug-In Enabled to yes.
  8. Click Save.
  9. If more than one cluster was deployed for the latest domain extension, repeat steps 4 through 8 until all the clusters are consistently updated.
  10. Click Activate Changes in the Change Center.
  11. Restart all Managed Servers in all of the clusters that you modified in this chapter.

13.11.4 Validating the Oracle SOA Suite URLs Through the Load Balancer

To validate the configuration of the Oracle HTTP Server virtual hosts and to verify that the hardware load balancer can route requests through the Oracle HTTP Server instances to the application tier:

  1. Verify that the server status is reported as Running in the Administration Console.

    If the server is shown as Starting or Resuming, wait for the server status to change to Started. If another status is reported (such as Admin or Failed), check the server output log files for errors.

  2. Verify that you can access these URLs:

    • https://soa.example.com:443/soa-infra

    • https://soa.example.com:443/integration/worklistapp

    • https://soa.example.com:443/sdpmessaging/userprefs-ui

    • https://soa.example.com:443/soa/composer

  3. Verify that Identity Service can be invoked successfully on the application tier by accessing the following load balancer URL: 
    https://soa.example.com:443/integration/services/IdentityService/identity?WSDL

13.12 Post-Configuration Steps for Oracle SOA Suite

After you install and configure Oracle SOA Suite, consider the following post-configuration tasks.

13.12.1 Configuring Oracle Adapters for Oracle SOA Suite

If the Oracle SOA Suite applications you are developing take advantage of any of the Oracle adapters for Oracle SOA Suite, then you should make sure the adapters are configured to work efficiently and securely in the enterprise topology.

See the following topics for more information.

13.12.1.1 Enabling High Availability for Oracle File and FTP Adapters

If the Oracle SOA Suite applications you are developing or deploying require the Oracle File and FTP Adapters, you must configure the adapters for high availability in the enterprise deployment topology.

Use the following sections to complete this task.

13.12.1.1.1 Understanding the Oracle File and FTP Adapter Configuration

The Oracle File and FTP adapters enable a BPEL process or an Oracle Mediator to read and write files on private file systems and on remote file systems through the FTP (File Transfer Protocol).

When configured properly, these adapters support high availability for an active-active topology with Oracle BPEL Process Manager and Oracle Mediator service engines for both inbound and outbound operations.

For general information about this task, see Configuring Oracle File and FTP Adapters in Oracle Fusion Middleware Understanding Technology Adapters. The instructions provided here are specific to the Oracle SOA Suite enterprise deployment.

Note:

The File Adapter picks up a file from the inbound directory, processes it, and then outputs a file to the output directory. Because the File Adapter is non-transactional, files can be processed twice. As a result, it is possible to get duplicate files when there is failover in the RAC backend or in the SOA managed servers.

13.12.1.1.2 Configuring the Oracle File Adapter in the Administration Console

To make the Oracle File Adapter highly available, first modify the Oracle File Adapter deployment descriptor for the connection-instance corresponding to eis/HAFileAdapter.

You can perform this task from the Oracle WebLogic Server console:

  1. Navigate to and log into the Oracle WebLogic Server Administration Console.

    For example:

    http://ADMINVHN:7001/console

    Note:

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

  2. In the left pane of the console, click Deployments.

  3. Locate the FileAdapter resource adapter in the Summary of Deployments table.

    Description of GUID-4FFFCBEB-8655-4847-A3F0-EF9D00044924-default.gif follows
    Description of the illustration GUID-4FFFCBEB-8655-4847-A3F0-EF9D00044924-default.gif

  4. Click FileAdapter to display the Settings for FileAdapter page.

  5. Click Configuration.

  6. Click Outbound Connection Pools.

  7. Expand javax.resource.cci.ConnectionFactory to see the configured connection factories.

  8. Click eis/HAFileAdapter.

    The Outbound Connection Properties for the connection factory appears (Figure 13-1).

    Figure 13-1 Oracle WebLogic Server Console - Settings for javax.resource.cci.Connectionfactory

    Description of Figure 13-1 follows
    Description of "Figure 13-1 Oracle WebLogic Server Console - Settings for javax.resource.cci.Connectionfactory"

  9. Click Lock & Edit.

    The property value column becomes editable (you can click on any of the rows in the Property Value column and modify the value).

  10. Enter the values as shown in Table 13-2.

    Note:

    Update controlDir and check other values against the default values as mentioned in Table 13-2.

    Table 13-2 Values to Provide for the javax.resource.cci.Connectionfactory

    Parameter Description

    controlDir

    Enter the directory where you want the control files to be stored. You must set it to a shared location if multiple WebLogic Server instances run in a cluster. Structure the directory for shared storage as follows:

    ORACLE_RUNTIME/domain_name/cluster_name/fadapter

    inboundDataSource

    Set the value to jdbc/SOADataSource.

    outboundDataSource

    Set the value to jdbc/SOADataSource.

    outboundDataSourceLocal

    Set the value to jdbc/SOALocalTxDataSource. This is the data source where the schemas corresponding to high availability are pre-created.

    outboundLockTypeForWrite

    Set the value to oracle if you are using Oracle Database. By default the Oracle File and FTP Adapters use an in-memory mutex to lock outbound write operations. You must choose from the following values for synchronizing write operations:

    • memory: The Oracle File and FTP Adapters use an in-memory mutex to synchronize access to the file system.

    • oracle: The adapter uses Oracle Database sequence.

    • db: The adapter uses a pre-created database table (FILEADAPTER_MUTEX) as the locking mechanism. You must use this option only if you are using a schema other than the Oracle Database schema.

    • user-defined: The adapter uses a user-defined mutex. To configure the user-defined mutex, you must implement the mutex interface: "oracle.tip.adapter.file.Mutex" and then configure a new binding-property with the name "oracle.tip.adapter.file.mutex" and value as the fully qualified class name for the mutex for the outbound reference.

    workingDirectory

    Leave this value as "default".

  11. Click Save after you update the properties. The Save Deployment Plan page appears.

  12. Create DEPLOY_PLAN_HOME directory.

    mkdir -p DEPLOY_PLAN_HOME/soaedg_domain

    In this example, replace DEPLOY_PLAN_HOME with the actual path to the deployment plan directory defined in File System and Directory Variables Used in This Guide.

  13. Enter a shared storage location for the deployment plan. The directory structure is as follows:

    DEPLOY_PLAN_HOME/soaedg_domain/FileAdapterPlan.xml

  14. Click Save and Activate to save and apply your changes.

  15. Update the deployment in the console:

    1. Click Deployments.

    2. Click Lock & Edit.

    3. Select the File Adapter.

    4. Click Update.

    5. Select Update this application in place with new deployment plan changes (A deployment plan must be specified for this option.) and select the deployment plan saved in a shared storage location; all servers in the cluster must be able to access the plan.

    6. Click Finish.

    7. Activate the changes.

  16. Verify that the FileAdapter deployment is activated and running:

    1. In the Administration Console, click Deployments in the left pane.

    2. Locate the FileAdapter deployment in the Deployments table.

    3. If it is not in the active state, then select FileAdapter under Summary of Deployments, Select Start, and then Servicing All Requests.

13.12.1.1.3 Editing the JCA File Within the Composite Application

After you have configured the FileAdapter deployment in the Administration Console, you can edit the .jca file that is included in the composite applications to be deployed so that they can use the connection factory configured in the previous steps, as shown in Example 13-2.

Note:

The location attribute is set to eis/HAFileAdapter for the connection factory.

Example 13-2 Example of the File Adapter .JCA File Modifications for an Enterprise Deployment

<adapter-config name="FlatStructureOut"
                adapter="File Adapter"
                xmlns="http://platform.integration.oracle/blocks/adapter/fw/metadata">
     <connection-factory location="eis/HAFileAdapter" adapterRef=""/>
     <endpoint-interaction portType="Write_ptt" 
                           operation="Write">
          <interaction-spec className="oracle.tip.adapter.file.outbound.FileInteractionSpec">
                <property../>
                <property../>
          </interaction-spec>
     </endpoint-interaction>
</adapter-config>
13.12.1.1.4 Configuring the Oracle FTP Adapter

If your application requires an FTP Adapter, then repeat the procedures Configuring the Oracle File Adapter in the Administration Console and Editing the JCA File Within the Composite Application, with the following differences:

  • Select the FtpAdapter deployment in the list of deployments in the Administration Console.

  • Modify the adapter properties for high availability. Refer Table 13-2for details.

  • Enter a shared storage location for the deployment plan. The directory structure is as follows: 
    DEPLOY_PLAN_HOME/soaedg_domain/FtpAdapterPlan.xml

  • Update the ControlDir property so it points to the following location:

    ORACLE_RUNTIME/domain_name/cluster_name/ftadapter

13.12.1.2 Enabling High Availability for Oracle JMS Adapters

When the Oracle JMS adapter communicates with multiple servers in a cluster, the adapter's connection factory property FactoryProperties must list available servers. If it does not list servers, the connection establishes to only one random server. If that particular server goes down, no further messages are processed.

To verify the adapter's JCA connection factory:

  1. Log into your Oracle WebLogic Server Administration Console using the following URL:

    http://ADMINVHN:7001/console

    Note:

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

  2. Click Deployments in the left pane for Domain Structure.

  3. Click JmsAdapter under Summary of Deployments on the right pane.

  4. Click the Configuration tab.

  5. Click the Outbound Connection Pools tab and expand oracle.tip.adapter.jms.IJmsConnectionFactory to see the configured connection factories.

  6. Click the specific instance you are using (for example, eis/wls/Queue). The Outbound Connection Properties for the connection factory opens.

  7. Click Lock & Edit.

  8. In the FactoryProperties field (click on the corresponding cell under Property value), enter the following, all on one line, separated by semicolons:

    java.naming.factory.initial=weblogic.jndi.WLInitialContextFactory;
java.naming.provider.url=t3://SOAHOST1:8001,SOAHOST2:8001;
java.naming.security.principal=weblogic;
java.naming.security.credentials=mypassword

  9. Click Save after you update the properties. The Save Deployment Plan page appears.

  10. Enter a shared storage location for the deployment plan. The directory structure is as follows:

    DEPLOY_PLAN_HOME/soaedg_domain/JMSAdapterPlan.xml

  11. Click Save and Activate.

Update the deployment in the console:

  1. Click Deployments.
  2. Click Lock & Edit
  3. Select the JMS Adapter.
  4. Click Update.
  5. Select Update this application in place with new deployment plan changes (A deployment plan must be specified for this option.) and select the deployment plan saved in a shared storage location; all servers in the cluster must be able to access the plan.
  6. Click Finish.
  7. Activate the changes.

13.12.1.3 Enabling High Availability for the Oracle Database Adapter

To ensure High Availability while leveraging the Oracle Database Adapter, the Logical Delete Polling Strategy is used normally as it performs better than a physical delete. However, when you have a clustered environment where multiple nodes are polling for the same data, a single record might get processed more than once. To avoid this problem, Oracle Database Adapter uses a distributed polling technique that uses an Oracle Database feature called skip locking.

If you were using the Logical Delete Polling Strategy approach previously, you can simply remove (in db.jca) or clear (Logical Delete Page of wizard) the MarkReservedValue, and you automatically get skip locking.

The benefits of using skip locking over a reserved value include:

  • Skip locking scales better in a cluster and under load.

  • All work is in one transaction (as opposed to update/reserve, then commit, then select in a new transaction), so the risk of facing a non-recoverable situation in a high availability environment is minimized.

  • No unique MarkReservedValue must be specified. Previously, for this to work you would have to configure a complex variable, such as R${weblogic.Name-2}-${IP-2}-${instance}.

If you are using Logical Delete polling, and you set MarkReservedValue, skip locking is not used.

For more information, see "Scalability" and "Polling Strategies" in the Oracle Fusion Middleware User's Guide for Technology Adapters.

13.12.2 Enabling SSL Communication Between the SOA Servers and the Hardware Load Balancer

After you extend the domain with Oracle SOA Suite, 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 SOA Composite applications and web 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.

13.12.3 Considerations for sync-async interactions in a SOA cluster

In a SOA cluster, the following scenarios are not supported:

  • Synchronous BPEL process with mid-process receive.

  • Synchronous BPEL process calling asynchronous services.

  • Callback from synchronous processes.

13.13 Enabling Automatic Service Migration and JDBC Persistent Stores for Oracle SOA Suite

To ensure that Oracle SOA Suite is configured for high availability, configure the Oracle SOA Suite Managed Servers for automatic service migration.

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

For additional high availability and reliability, Oracle recommends configuring transaction log stores and JMS stores in a database. For more information, see Using Persistent Stores for TLOGs and JMS in an Enterprise Deployment.
