Hi Everyone.. I just want to clarify that I have clear understanding on Aggregation concept..
Aggregate control :: starts the aggregation,
Aggregation Request ::
It splits the message into individual requests. sends Reply identifier (In the case MQ)
Aggregation Reply ::
collects all the messages and generate COMAGGREGATEREPLYBODY (Only when it reach timeout, out). It keeps the message as original when it reached as unknown.
Does it consider 1st request -- 1 st reply match ?
Please correct me.. I guess I am confused..

No, you got it right.
However let's be more specific about the one request / one reply....
It should probably read one request / one aggregate reply...
Which means you will have one reply from multiple sources.
If you need multiple replies from a single source, you would use a collection node. Nothing prevents you from using those together within an aggregation.
Have fun

You are a saviour for me today.. Thanks for elucidation..
Just wanna confirm that timeout = message reached after time mentioned on control node.
Unknown = message reached after time mentioned on control node + unknown time mentioned reply node..
Right? |

Quick observation will prove your point.
