Upgrading Oracle B2B Applications 12-5

12.3.2 Considerations When Upgrading B2B-Related Oracle BPEL Processes

By default, Oracle SOA Suite 10g uses Oracle Streams Advanced Queuing AQ as the default connection between the Oracle BPEL Process Manager and Oracle B2B. The Oracle AQ connection relies on a data source being available on the OC4J server. When you upgrade to Oracle SOA Suite 11g, the required data source used by Oracle AQ is not available by default. As a result, you should consider the following when upgrading to Oracle B2B 11g and Oracle SOA Suite 11g: ■ Before you upgrade to Oracle B2B 11g, create a data source in Oracle WebLogic Server that references the Oracle B2B 10g database. Note the JNDI name you provide for the database. For more information, see Create JDBC data sources in the Oracle Fusion Middleware Oracle WebLogic Server Administration Console Online Help. ■ After the upgrade to Oracle B2B 11g, open the Open AQ Adapter External Reference, and enter JNDI name for the new Oracle WebLogic Server data source on the Service Connection page of the Connection wizard. Note that when you open your Oracle SOA Suite 10g application in Oracle JDeveloper 11g, the Oracle JDeveloper Migration Utilty upgrades your application and makes the following related changes to your projects. These changes allow you to continue using the Oracle AQ connection between the Oracle B2B and Oracle BPEL Process Manager processes: ■ For Oracle BPEL Process Manager projects, the variables used by the Oracle AQ connection are upgraded automatically to properties within an Oracle BPEL Process Manager assign statement or transformation map within the BPEL process file. ■ For Oracle Enterprise Service Bus projects, the variables used by the Oracle AQ connection in are removed automatically from the 10g XSLT map file and upgraded to properties within an assign values field in Oracle Mediator. Alternatively, you can recreate your projects in Oracle JDeveloper 11g, using the newer Oracle Fusion Middleware 11g features for defining the connections between Oracle Mediator projects and Oracle BPEL Process Manager processes. For more information, see the Oracle Fusion Middleware Developers Guide for Oracle SOA Suite.
