Use this task to configure the properties of the message listener service for an application server, to support message-driven beans deployed against listener ports.

 

Overview

If the JMS provider does not have a JCA 1.5 resource adapter, such as the V5 Default Messaging and WebSphere MQ, configure JMS message-driven beans against a listener port (as in WAS v5).

If you want to deploy an enterprise application to use message-driven beans with listener ports, use this task to browse or change the configuration of the message listener service for an application server.

To configure the message listener service for an application server, use the administrative console to complete the following steps:

 

Procedure

1. Display the listener service settings page:

   Servers | Application Servers | appserver | Communications | Messaging | Message Listener Service

2. Optional: Browse or change the value of properties for the message-driven bean thread pool.

   1. Click Thread Pool

   2. Change the following properties, to suit your needs:

      Minimum size

      The minimum number of threads to allow in the pool.

      Maximum size

      The maximum number of threads to allow in the pool.

      Thread inactivity timeout

      The number of milliseconds of inactivity that should elapse before a thread is reclaimed. A value of 0 indicates not to wait and a negative value (less than 0) means to wait forever.

      Note: The administrative console does not allow you to set the inactivity timeout to a negative number. To do this modify the value directly in the config.xml file.

      Allow thread allocation beyond maximum thread size

      Select this check box to enable the number of threads to increase beyond the maximum size configured for the thread pool.

   3. Click OK.

3. Optional: Specify any of the following optional properties that we need, as Custom properties of the message listener service:

   NON.ASF.RECEIVE.TIMEOUT
   MQJMS.POOLING.TIMEOUT
   MQJMS.POOLING.THRESHOLD
   MAX.RECOVERY.RETRIES
   RECOVERY.RETRY.INTERVAL

   To browse or change the properties, complete the following steps:

   1. Click Custom properties

   2. For each custom property, specify a value to suit your needs. 9

      If you have not specified a property before:

      1. Click New.

      2. Type the name of the property.

      3. Type the value of the property.

      4. Click OK.

4. Save your changes to the master configuration.

5. To have the changed configuration take effect, stop then restart the Application Server.
