If the application server is configured with one or more
message-driven beans (MDBs) that do not use asynchronous messaging
and are bound to a Java EE Connector Architecture (JCA) Version 1.5 resource
adapter, and the resource adapter supports inbound message processing,
the adapter must be defined to run only a maximum of 1 servant region.
If you use the IMS™ Connect for Java (IC4J)
resource adapter or an adapter that is driven by asynchronous messaging,
you can configure the servant regions through the adapter configuration.
Avoid trouble: If the application server is configured with one
or more message-driven beans (MDBs) that are bound to service integration
messaging or WebSphere MQ messaging using a resource adapter, which
means that the MDBs use activation specifications rather than listener
ports, then you must enable the CRA process for the application server.
Use the WebSphere MQ CRA settings panel or the manageWMQ command to
include starting the CRA process as part of starting an application
server.
