Using message-driven beans with JCA version 1.5 resource adapters

You must redefine the servant region for any message-driven beans that are connected to J2EE Connector Architecture (JCA) Version 1.5 resource adapters that support inbound message processing.

About this task

If the application server is configured with one or more message-driven beans (MDBs) that are bound to a J2EE 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, however, you can configure this adapter to run multiple servant regions.

A servant can be configured to a maximum of 1 servant region by using the administrative console.

Procedure

  1. Open the administrative console.
  2. Select Servers.
  3. Select Application Servers.
  4. Select the server you want to configure.
  5. Under Server Infrastructure, expand Java and Process Management.
  6. Select Process Definition.
  7. SelectServant.
  8. Under Additional Properties, select Environment Entries. This causes a panel with the heading Application servers > server_name > Process Definition > Servant > Custom Properties to appear.
  9. Select New. A panel with three General Properties fields appears. This is where you create the environment variable for controlling the number of servant regions.
  10. In the Name field, enter wlm_maximumSRcount.
  11. In the Value field, enter 1.
  12. Select Apply.
