Setting up IBM MQ for MSCS clustering

You configure IBM® MQ for clustering by making the queue manager the unit of failover to MSCS. You define a queue manager as a resource to MSCS, which can then monitor it, and transfer it to another computer in the cluster if there is a problem.

To set your system up for this, you start by installing IBM MQ on each computer in the cluster.

As the queue manager is associated with the IBM MQ installation name, the IBM MQ installation name on all the computers in the cluster should be the same. See Installing and uninstalling.

The queue managers themselves need to exist only on the computer on which you create them. In the event of a failover, the MSCS initiates the queue managers on the other computer. The queue managers, however, must have their log and data files on a cluster shared disk, and not on a local drive. If you have a queue manager already installed on a local drive, you can migrate it using a tool provided with IBM MQ; see Moving a queue manager to MSCS storage. If you want to create new queue managers for use with MSCS, see Creating a queue manager for use with MSCS.

After installation and migration, use the MSCS Cluster Administrator to make MSCS aware of your queue managers; see Putting a queue manager under MSCS control.

If you decide to remove a queue manager from MSCS control, use the procedure described in Removing a queue manager from MSCS control.
