Configuring servant regions for message-driven beans with JCA version 1.5 resource adapters
For any message-driven beans (MDBs) that are not driven by asynchronous messaging or the IMS Connect for Java (IC4J) resource adapter, you must redefine the servant region for those beans that are connected to Java™ Platform, Enterprise Edition (Java EE) 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 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.
避免困難: 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 Control Region Adjunct (CRA) process for the application
server. To include starting the CRA process as part of starting an
application server, either select Enable JCA based inbound
message delivery on the JMS provider settings panel, or
use the manageWMQ command.gotcha

Procedure
- Open the administrative console.
- Select Servers > Server Types > WebSphere application servers.
- Select the server you want to configure.
- Under Server Infrastructure, expand Java and Process Management.
- Select Process Definition.
- Select Servant.
- Under Additional Properties, select Environment Entries. This causes a panel with the heading Application servers > server > Process Definition > Servant > Custom Properties to appear.
- 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.
- In the Name field, enter wlm_maximumSRcount.
- In the Value field, enter 1. A servant can be configured to a maximum of 1 servant region by using the administrative console.
- Select Apply.
