Maintaining the WebSphere MQ resource adapter

The WebSphere® MQ resource adapter is used by all applications that perform JMS messaging with the WebSphere MQ messaging provider. The WebSphere MQ resource adapter is usually updated automatically when you apply WebSphere Application Server fix packs, but if you have previously manually updated the resource adapter you must manually update your configuration to ensure that maintenance is applied correctly.

About this task

Applying a WebSphere Application Server fix pack does not automatically update the version of the WebSphere MQ resource adapter used by servers on nodes where the WebSphere MQ resource adapter has previously been manually updated.

• To migrate the configuration of all servers in the cell to use the latest version of the WebSphere MQ resource adapter contained in the WebSphere Application Server installation, see Ensuring that servers use the latest available WebSphere MQ resource adapter maintenance level.
• If you want a specific version of the WebSphere MQ resource adapter to be installed, and the version you require is not available in a WebSphere Application Server fix pack, or an interim fix, see Installing a specific maintenance level of the WebSphere MQ resource adapter.
