MQSeries.net :: View topic - Help to understand how aggregation node works

WBI_user

I am learning to use the aggregateion node. I have read "Using CC manual chapter 6". There is a few questions that I need some help to clarify.
I have actually built a test flow and looked at the control message it shows:
ComIbmAggregateControlNode.(XML.attr)brokerUUID='9862c293ed0000000080acf9d8c
a2fff'
ComIbmAggregateControlNode.(XML.attr)aggregateName='TEST'
ComIbmAggregateControlNode.(XML.attr)replyGroupId='4867980592d04008bc36ef6d3
58d8b3b'
ComIbmAggregateControlNode.(XML.attr)timeout='0'
ComIbmAggregateControlNode=''

1. In the manual it says "When a message arrives at the 'in' terminal of an
AggregateReply node, it is examined to see if it is an expected reply
message." It does not explain base on what is the validation checked ?
I can see that there is a replyGroupId in the control message. But this Id
does not show up any where in the request message that we sent out. Unless
there is something that I cannot see, how does the reply sent by the
application know what to set in order for it to be valid.

2. There is also no where that I can see how we can tell the number of
replies that can appear on the reply queue. Is it a rule that one request
can only generate one reply ? Can one request generate more than one reply ?
