Cluster queues
To use WebSphere MQ clusters, you need to define the following objects:
- A local queue called the SYSTEM.CLUSTER.COMMAND.QUEUE, which is used to
communicate repository changes between queue managers. Messages written to
this queue contain updates to the repository data to be applied to the local
copy of the repository, or requests for repository data.
- A local queue called SYSTEM.CLUSTER.REPOSITORY.QUEUE, which is used to
hold a persistent copy of the repository.
- A local queue called SYSTEM.CLUSTER.TRANSMIT.QUEUE, which is the transmission
queue for all destinations in the cluster. For performance reasons you should
define this queue with an index type of CORRELID (as shown in the sample queue
definition).
These queues typically contain large numbers of messages.
You cannot define these queues as shared queues.
