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>
