Maintaining the WebSphere MQ JCA resource adapter

The WebSphere® MQ JCA 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 in some circumstances you might need to manually update your configuration to ensure that maintenance is applied correctly.

About this task

In the following circumstances, when you apply a WebSphere Application Server fix pack, the application servers in your environment will not use the latest version of the WebSphere MQ resource adapter contained in that fix pack:
The application server or deployment manager profile was created with WebSphere Application Server Version 7.0.0.0, without any fix packs applied.
After WebSphere Application Server Version 7.0 Fix Pack 1 or later has been applied, the JVM logs for an application server that is experiencing this problem show the following version information for the WebSphere MQ resource adapter:
WMSG1703I: RAR implementation version 7.0.0.0-k700-L080820
The WebSphere MQ JCA resource adapter has been manually updated on some nodes in your environment.
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.
You created a profile with WebSphere Application Server Version 7.0 Fix Pack 1 or later applied, and then uninstalled all fix packs from the installation to return to maintenance level 7.0.0.0.
The JVM logs of an application server that is experiencing this problem show the following error message:
WMSG1625E: It was not possible to detect the WebSphere MQ messaging provider code at the specified path <null>
