Store and Forward Queues and Remote Queue References

Because S&F queues can accept messages for any queue on a given queue manager, they can appear to be in conflict with a remote queue reference. In such cases the remote queue reference takes precedence, because it is more specific. So if we look again at our S&F queue resolution, but add a remote queue reference we can see that the message route resolution changes immediately, the S&F queue becomes irrelevant. We can see this in Figure 73

Figure 73. How routes using remote queue definitions take precedence over store-and-forward queue routes


that queue resolution finds the best (most exact) match for the message address.

So a message put to QueueAlias@TargetQM goes via the S&F queue (asynchronous transmission), but a put to TargetQueue@TargetQM goes synchronously via the remote queue reference.
