Cluster queues
A cluster queue is a queue that is hosted by a cluster queue manager and made available to other queue managers in the cluster.
A cluster queue definition is advertised to other queue managers in the cluster. The other queue managers in the cluster can put messages to a cluster queue without needing a corresponding remote-queue definition. A cluster queue can be advertised in more than one cluster by using a cluster namelist.
When a queue is advertised, any queue manager in the cluster can put messages to it. To put a message, the queue manager must find out, from the full repositories, where the queue is hosted. Then it adds some routing information to the message and puts the message on a cluster transmission queue.
A cluster queue can be a queue that is shared by members of a queue
sharing group in IBM MQ for z/OS .
