Deployment descriptors are BPEL process service component properties used at runtime by Oracle WebLogic Server, Oracle Enterprise Manager Fusion Middleware Control, or both. You set these properties during design time in the composite.xml file of the SOA composite application. Examples of deployment descriptor properties include completionPersistPolicy, inMemoryOptimization, oneWayDeliveryPolicy, transaction, nonBlockingInvoke, and others.

For more information about available deployment descriptor properties, see How to Define Deployment Descriptor Properties in the Property Inspector and Transaction and Fault Propagation Semantics in BPEL Processes.
