Chapter 5 - Using the Messaging 
Adapter 
When using the IBM WebSphere MQ adapter for a source, messages are served by 
default from the queue in a first-in-first-out (FIFO) manner unless you specify a 
particular message using a message or correlation identifier. When using the 
adapter for a target, messages are placed on the queue you specify. 
Message identifiers are assumed to be unique for a particular queue. If more than 
one message in the same queue has the same message identifier, it is assumed 
that each message is part of a packet. All messages with the same message 
identifier are extracted and appended in FIFO order.
