Nobody on this forum is going to tell you anything about the internals of the product - that is IBM's intellectual property. Everything that you need to know *should* be covered in the Knowledge Center. Which topics have you read?

Hi, i have read aggregation samples and read about aggregation nodes.
it explains that usage and configuration of nodes.


but how aggregate reply is understanding the behaviour of fanout flows

if message has been send to the mqoutput and then aggregate request node, so on what basis aggregate reply is making response folder.

even i was debugging the flow only mq headers were shown in between of mqinput and aggregate reply.

I don't understand the question.

Do you mean "how does the aggregate node know which messages belong to a given aggregation?"

Or something else?

ComIbmAggregateReplyBody.<aggregate request <folder name>>.xmlnsc.body

thanks mqjeff,
now i am facing slowness issue in the aggregated response message

kept timeout value as 120 in aggregate control node and 5 in unknown message timeout of aggregate reply node.

i got the all response from fanout services with in 2 to 3 seconds but while sending aggregated response messages it takes 6 to 7 seconds.

please suggest how to send response message faster.

Regards
Sukhendra

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

How are you trying to disgnose the problem?
Have you put Trace Nodes into your flow?
Have you used the Debugger or UserTrace?
