Tuning messaging
To tune asynchronous messaging, you can, for example, configure
message-driven bean (MDB) throttling for a JCA 1.5-compliant messaging
provider. On z/OS® platforms
you can tune also MDB processing and tune destinations for the WebSphere® MQ messaging provider.
About this task
To tune your asynchronous messaging, complete one or more of the following steps.
Procedure
- Configure MDB throttling for a JCA 1.5-compliant messaging
provider in one of the following ways, depending on your choice of
messaging provider:
- For the default messaging provider, complete the task Configuring MDB throttling for the default messaging provider.
- For the IBM MQ messaging provider, either set the maximum server sessions property on the "IBM MQ messaging provider activation specifications advanced properties" page, or the maxPoolSize property when using the createWMQActivationSpec or modifyWMQActivationSpec wsadmin commands.
- For a third-party JCA 1.5-compliant JMS messaging provider, refer to the generic method of message throttling described in Throttling inbound message flow for JCA 1.5 message-driven beans.
Tune MDB processing on z/OS.
- Tune messaging destinations for the WebSphere MQ.
Subtopics
Tuning messaging performance for the default messaging provider
To help optimize performance, you can set tuning properties that control the performance of message-driven beans and other messaging applications.Configuring MDB throttling for the default messaging provider
Use this task to configure the throttling of messages for message-driven bean that you have deployed as JCA 1.5 resources on the default messaging provider.Tuning messaging destinations for the IBM MQ messaging provider
You can optimize performance of message-driven bean (MDB) or other applications that use the IBM MQ messaging provider by configuring the properties of IBM MQ messaging provider destinations.Tuning message-driven bean processing on z/OS by using IBM MQ as the messaging provider in ASF mode
You can tune message-driven beans processing when you are running WebSphere Application Server on the z/OS platform, where IBM MQ is the messaging provider, and the message-driven bean has been deployed in Application Server Facilities (ASF) mode.Throttling inbound message flow for JCA 1.5 message-driven beans
This topic describes how to throttle message delivery for message-driven beans (MDB) which are deployed as message endpoints for Java Platform, Enterprise Edition (Java EE) Connector Architecture (JCA) Version 1.5 inbound resource adapters.Monitoring server session pools for listener ports
You can minimize the number of resources that server sessions use by enabling server session pool monitoring and defining the timeout value to be applied to a server session.
