Maintaining the IBM MQ resource adapter

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

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

Tasks

• To migrate the configuration of all servers in the cell to use the latest version of the IBM MQ resource adapter contained in the WAS installation, see Ensuring that servers use the latest available IBM MQ resource adapter maintenance level.

• To have a specific version of the IBM MQ resource adapter to be installed, and the version you require is not available in a WAS fix pack, or an interim fix, see Install a specific maintenance level of the IBM MQ resource adapter.

Subtopics

• Ensuring that servers use the latest available IBM MQ resource adapter maintenance level
  To ensure that the IBM MQ resource adapter is automatically updated to the latest available maintenance level when applying WAS fix packs, we can configure all servers in the environment to use the latest version of the resource adapter contained in the WAS fix pack that we have applied to the installation of each node.
• Install a specific maintenance level of the IBM MQ resource adapter
  If we require a specific version of the IBM MQ resource adapter to be installed and the version you require is unavailable in a WAS fix pack, or an interim fix, we can install the resource adapter using the administrative console.
