Passing messages through your system

Figure 22. Three methods of passing messages through your system
Three methods of passing messages through your system. Refer to the text following the diagram for details of the configuration shown.

Following on from the technique shown in Figure 21, where you saw how an alias flow is captured, Figure 22 illustrates the ways networks are built up by bringing together the techniques we have discussed.

The configuration shows a channel delivering three messages with different destinations:

  1. 'QB at QMC'
  2. 'QB at QMD_norm'
  3. 'QB at QMD_PRIORITY'

You must pass the first message flow through your system unchanged; the second message flow through a different transmission queue and channel, while reverting the messages from the alias queue manager name 'QMD_norm' to the physical location 'QMD'; and the third message flow simply chooses a different transmission queue without any other change.

In a clustering environment, all messages are passed through the cluster transmission queue, SYSTEM.CLUSTER.TRANSMIT.QUEUE. This is illustrated in Figure 4.

The following methods describe techniques applicable to a distributed-queuing environment:
