Patching Running Instances of a SOA Composite

Oracle SOA Suite 12c (12.2.1) supports Composite Instance Patching, which enables you to patch running instances of a composite and recover faulted instances after patching the runtime. You can only include those fixes in the patch that are compatible with Composite Instance Patching. Use the SOA Patch Developer role in Oracle JDeveloper to make the fixes and create the patch.

Composite Instance Patching enables you to deliver urgent composite fixes that can be picked up by long running instances. You can make compatible/allowed changes without aborting in-flight instances. If a patched running instance comes across a business process that has been fixed by the patch, say a BPEL transformation, then it picks up the fixes applied to the business process.

Note:

This SOA Suite feature is part of Oracle Integration Continuous Availability. Please refer to the Oracle Fusion Middleware Licensing Information for more details on Oracle SOA Suite for Middleware Options.

When designing the patch, the SOA Patch Developer mode in JDeveloper automatically disables changes that cannot be made to the patch. Some of the compatible changes that you can make include:

  • Non-schema related XSLT changes, changes to fault policy, sensor data, and analytics data.

  • Compatible BPEL changes such as transformation activity, assign operations, etc.

  • JCA Adapter configuration properties.

You do not specify any composite version during deployment. The composite revision that you create the patch for, in Oracle JDeveloper, is the composite revision to which the patch is deployed.

You can validate the patch before deploying.

Use the following steps to create and deploy the patch to runtime.

  1. Use the SOA Patch Developer role in Oracle JDeveloper to make changes to your composite and create the patch.
  2. Validate and deploy the patch using the WLST command-line utility.
    See Verifying and Deploying the Patch Using WLST for details.

    If the patch contains fixes to your composite, you can recover faulted instances in Enterprise Manager Fusion Middleware Control after deploying the patch.
