To ensure that the WebSphere® MQ
JCA resource adapter is automatically updated to the latest available
maintenance level when you apply WebSphere Application Server fix packs, you
can configure all servers in your environment to use the latest version
of the resource adapter contained in the WebSphere Application Server fix pack that
you have applied to the installation of each node.
About this task
Use this task if any of the following circumstances apply
to your configuration, and you want to configure all servers in your
environment to use the latest version of the WebSphere MQ JCA resource adapter:
When you have performed the following steps for all cells
and single server installations in your environment, your servers
will automatically receive maintenance to the WebSphere MQ JCA resource adapter when
a new WebSphere Application Server fix
pack is applied.
Procedure
- Ensure that you have applied up to date maintenance to
all installations in your environment, so that Fix Pack 1 or higher
is now installed.
- Start the application server.
If the profile is part of a network deployment configuration, start the deployment manager and all node agents. If the profile contains an administrative agent, start the administrative agent.
- Copy the following Jython script into a file called convertWMQRA.py, then save it into the profile_root/bin directory.
ras = AdminUtilities.convertToList(AdminConfig.list('J2CResourceAdapter'))
for ra in ras :
desc = AdminConfig.showAttribute(ra, "description")
if (desc == "WAS 7.0 Built In WebSphere MQ Resource Adapter") or (desc == "WAS 7.0.0.1 Built In WebSphere MQ Resource Adapter"):
print "Updating archivePath and classpath of " + ra
AdminConfig.modify(ra, [['archivePath', "${WAS_INSTALL_ROOT}/installedConnectors/wmq.jmsra.rar"]])
AdminConfig.unsetAttributes(ra, ['classpath'])
AdminConfig.modify(ra, [['classpath', "${WAS_INSTALL_ROOT}/installedConnectors/wmq.jmsra.rar"]])
AdminConfig.save()
#end if
#end for
- Use the wsadmin tool to run the Jython script that you have just created.
Open a command prompt and navigate to the profile_root/bin directory, then enter the following command:wsadmin -lang jython -f convertWMQRA.py
Note: If you run the script against a profile that is part of a network deployment configuration, the script updates all profiles that need updating in that configuration.
- If you are running in a network deployment configuration, ensure that the node agents are fully re-synchronized.
For more information, see Synchronizing nodes using the wsadmin scripting tool or Adding, managing, and removing nodes.
- Stop all servers in the profile.
If the profile is part of a network deployment configuration, also stop any cluster members in the configuration, stop all node agents in the configuration, and stop the deployment manager. If
the profile contains an administrative agent, stop the administrative
agent.
- Run the osgiCfgInit command from the profile_root/bin directory.
If the profile is part of a network deployment configuration, run the osgiCfgInit command from the profile_root/bin directory of every profile that is part of the configuration.
Note: The osgiCfgInit command resets the class cache used by the OSGi runtime environment.
- Restart all servers in the profile.
If the profile is part of a network deployment configuration, also restart any cluster members in the configuration, restart all node agents in the configuration, and restart the deployment manager. If
the profile contains an administrative agent, restart the administrative
agent.
What to do next
If you continue to experience problems after performing the
steps described in this topic, and you have previously used the Update
resource adapter... button on the JMS Provider Settings
panel in the administrative console to update the WebSphere MQ resource
adapter on any nodes in your environment, it is possible that you
are experiencing the issue described in APAR PM10308.
