Queue names in transmission header

Destination queue names travel with the message in the transmission header until the destination queue has been reached.

The queue name used by the application, the logical queue name, is resolved by the queue manager to the destination queue name. In other words, the physical queue name. This destination queue name travels with the message in a separate data area, the transmission header, until the destination queue has been reached. The transmission header is then stripped off.

You change the queue manager part of this queue name when you create parallel classes of service. Remember to return the queue manager name to the original name when the end of the class-of-service diversion has been reached.
