Routing messages to and from clusters

Use queue aliases, queue manager aliases, and remote queue definitions to connect clusters to external queue managers and other clusters.

For details on routing messages to and from clusters, see the following subtopics:

  • Configure request/reply to a cluster
    Configure a request/reply message path from a queue manager outside a cluster. Hide the inner details of the cluster by using a gateway queue manager as the communication path to and from the cluster.
  • Configure request/reply from a cluster
    Configure a request/reply message path from a cluster to a queue manager outside the cluster. Hide the details of how a queue manager inside the cluster communicates outside the cluster by using a gateway queue manager.
  • Configure workload balancing from outside a cluster
    Configure a message path from a queue manager outside a cluster to any copy of a cluster queue. The result is to workload balance requests from outside the cluster to each instance of a cluster queue.
  • Configure message paths between clusters
    Connect clusters together using a gateway queue manager. Make queues or queue managers visible to all the clusters by defining cluster queue or cluster queue manager aliases on the gateway queue manager.
  • Queue manager aliases and clusters
    Use queue manager aliases to hide the name of queue managers when sending messages into or out of a cluster, and to workload balance messages sent to a cluster.
  • Reply-to queue aliases and clusters
    A reply-to queue alias definition is used to specify alternative names for reply information. Reply-to queue alias definitions can be used with clusters just the same as in a distributed queuing environment.
  • Queue aliases and clusters
    Use queue aliases to hide the name of a cluster queue, to cluster a queue, adopt different attributes, or adopt different access controls.
