Managing messaging with the IBM MQ messaging provider

Through the IBM® MQ messaging provider in WebSphere® Application Server, Java™ Message Service (JMS) messaging applications can use your IBM MQ system as an external provider of JMS messaging resources. To enable this approach, you configure the WebSphere MQ messaging provider in WebSphere Application Server to define JMS resources for connecting to any queue manager on the WebSphere MQ network.

Before you begin

If your business uses IBM MQ, and you want to integrate WebSphere Application Server messaging applications into a predominantly IBM MQ network, the IBM MQ messaging provider is a logical choice. However, there can be benefits in using another provider.

About this task

The WebSphere MQ messaging provider supports JMS 1.1 domain-independent interfaces (sometimes referred to as unified or common interfaces), and also supports the Java EE Connector Architecture (JCA) 1.5 activation specification mechanism for message-driven beans (MDBs) across all platforms supported by WebSphere Application Server.

You can use WebSphere Application Server to configure WebSphere MQ resources for applications (for example queue connection factories) and to manage messages and subscriptions associated with JMS destinations. You administer security through WebSphere MQ.

You can use WebSphere Application Server to coordinate global transactions including WebSphere MQ without configuring the extended transactional client.

In a mixed-version WebSphere Application Server cell, you can administer WebSphere MQ resources on nodes of all versions. However, some properties are not available on all versions. In this situation, only the properties of that particular node are displayed in the administrative console.

For publish and subscribe messaging with WebSphere MQ as an external JMS messaging provider you have several options:
  • [z/OS]With WebSphere MQ Version 6 on z/OS®, you can use a separate message broker product.
  • With WebSphere MQ Version 6 on distributed platforms, you can use either a separate message broker product, or the built-in publish and subscribe capability of WebSphere MQ.
  • With WebSphere MQ Version 7 or later on any platform you can use the built-in publish and subscribe capability of WebSphere MQ. Note that you cannot use WebSphere Message Broker Version 7 or later for this because it no longer provides a publish and subscribe capability.
