Configuring MDB throttling on the default messaging provider

Use this task to configure the throttling of messages for message-driven beans that you have deployed as JCA 1.5 resources on the default messaging provider.

About this task

Use this task if you want to throttle messages for a message-driven bean deployed as a J2EE Connector Architecture (JCA) 1.5 resource on the default messaging JMS provider.

The default messaging provider (the SIB JMS Resource Adapter) uses a special type of message throttling. You should use the throttling support described in this topic instead of the JCA 1.5 throttling of messages described in Throttling of inbound message flow for JCA 1.5 message-driven beans. You can leave the message-driven bean pools to the default size of 500.

The default messaging provider enables the throttling of message delivery to a message-driven bean through a configuration option on the JMS activation specification used to deploy the bean. This configuration option is labelled Maximum concurrent endpoints and can be found on the JMS activation specification panels in the administrative console.

Note: You might wish to tune the throttling of your MDBs, which is especially important on z/OS. Workload arriving on the destination the MDB is consuming from might use up more server resource and therefore obstruct other activities. An example of this is when restarting MDB applications you find a backlog of messages. The number of messages can be throttled so that the MDB can process them in the most efficient manner.

To configure the message throttling support of the default messaging provider (the SIB JMS Resource Adapter), use the administrative console to complete the following steps.
