3. Define a CLUSSDR channel on queue manager PARIS

 

Every queue manager in a cluster needs to define one cluster-sender channel on which it can send messages to its initial full repository. On PARIS, make the following definition for a channel called TO.LONDON to the queue manager whose network address is LONDON.CHSTORE.COM.

DEFINE CHANNEL(TO.LONDON) CHLTYPE(CLUSSDR) TRPTYPE(TCP)
CONNAME(LONDON.CHSTORE.COM) CLUSTER(INVENTORY)
DESCR('Cluster-sender channel from PARIS to repository at LONDON')

Now that you have completed all the definitions, if you have not already done so, start the channel initiator on WebSphere MQ for z/OS and, on all platforms, start a listener program on queue manager PARIS. The listener program listens for incoming network requests and starts the cluster-receiver channel when it is needed. See Establishing communication in a cluster for more information.

The cluster set up by this task looks like this:

Figure 1. The INVENTORY cluster with three queue managers

By making only two definitions, a CLUSRCVR definition and a CLUSSDR definition, we have added the queue manager PARIS to the cluster.

Now the PARIS queue manager learns, from the full repository at LONDON, that the INVENTQ queue is hosted by queue manager NEWYORK. When an application hosted by the system in Paris tries to put messages to the INVENTQ, PARIS automatically defines a cluster-sender channel to connect to the cluster-receiver channel TO.NEWYORK. The application can receive responses when its queue-manager name is specified as the target queue manager and a reply-to queue is provided.
