Creating and configuring a queue manager cluster

Since the queue managers in a cluster are logically associated and can share information with each other, this means that an application can put a message on a cluster queue from any queue manager in the cluster and the message is automatically routed to the queue manager where the cluster queue is defined. The amount of system administration is reduced because the cluster channels that the cluster queue managers use to exchange application messages are automatically defined as required.

IBM MQ Explorer provides wizards to help you to create and configure queue manager clusters and objects.

You cannot use the wizards to manage queue managers and objects that belong to more than one cluster (and, therefore, use namelists). However, you can still use the IBM MQ Explorer properties dialogs to edit the properties of the queue managers and objects if you want them to belong to more than one cluster.
