We have a request-response scenario, which has to generate an event if no response is received. Cannot use aggregation because the fan-out branches, is not predetermined. So, we are investigating the Timeout node provided in WBIMB v6.
Wanted to find out if any of the GURUS faced this scenario?
Any feedback is greatly appreciated. _________________ IBM Certified System Administrator

You can use aggregation if you have an unknown number of fan-outs. You just reuse one Request node. Your replies will then end up as children of the Folder.
There is a whitepaper on developerworks about using the timeout nodes. _________________ I am *not* the model of the modern major general. |

jefflowrey,
Thanks for referring to the white paper. It does have a lot more information than product documentation.
Think I cannot use aggregation because the branched events are distinct. And should run independent of other.
For instance consider
1-n request-response scenario (1 source and n destinations)
Application is segmenting the messages (Head + data+ Tail)...
- Source application sends the head
- Brokers determines n destinations
- Brokers request a response from n destinations
- Destination application responds back with the temp queue name i should send the data _________________ IBM Certified System Administrator

As long as there is a 1-1 between requests and replies, you can use aggregation. _________________ I am *not* the model of the modern major general. |

Aggregate works but requires that every message sent out thru the AggregateReq node has an unique msgid. _________________ IBM Certified System Administrator
