Chaining Store and Forward Queues

Pushing store and forward queues can be chained together into a more complex route, see Figure 74.

Figure 74. Pushing S&F queues chained together.


Note that the Store and Forward queue on LocalQM (SaFQueue@RemoteQM) has a Queue Manager Entry for TargetQM, but actually pushes to RemoteQM. LocalQM requires a connection definition to RemoteQM, but not to TargetQM. A message can then be transported via the intermediate S&F queue, see Figure 75.

This works because the combination of queue resolution and connection resolution on LocalQM results in the message being put to the S&F queue on RemoteQM, which can then move it to its destination. The chain of Store and Forward Queues could be arbitrarily long, with each queue manager in the chain needing to know only about the next queue manager in the chain. The Message Routes express this very succinctly, see Figure 76.
