Points to note about such a configuration

 

  1. The requesting application does not need to be aware of the underlying mechanism used for the delivery of messages.

  2. A potentially faster message delivery mechanism can be achieved for small messages.

  3. Multiple paths are available for message delivery (that is, the normal channel route and the intra-group queuing route).

  4. The intra-group queuing route, being potentially faster, is selected in preference to the normal channel route. Depending on the message characteristics, message delivery may be divided across the two paths. Hence, messages may be delivered out of sequence (though this is also possible if messages are delivered using only the normal channel route).

  5. Once a route has been selected, and messages have been placed on to the respective transmission queues, only the selected route will be used for message delivery. Any unprocessed messages on the SYSTEM.QSG.TRANSMIT.QUEUE are not diverted to transmission queue XQ1.
