Guys,
Is there any way that I can capture a specific request in an Aggregation flow that timed out? From my AggregationRequest I fan out to 4 services. If one of the services timed out for whatever reason, how can I report on that? I need to build my error logs to state that a specific service did not return, rather than just stating in the logs that I had a timeout from host.
Thanks |

Woudln't you see that one of the folders you specified to receive the responses was empty and assume thats the one you didnt get the response from?

Thanks for the quick response, Wayne!
Please excuse me, I am quite new to Aggregation. I know that it stores the reference to the Aggregation in the Database, but I'm not too sure where. Also, I am not too sure how to pick it up. My way of thinking was possibly in the lines of another node that interrogates the database to see which response didn't come back - and then using this info in an exception flow.
If at all possible, could you please elaborate.
Thank you in advance |

Perhaps you should read up on the nodes and look at the sample in the samples gallery. Basically, when you "spilt out" a flow, you tell the nodes which folder to put the response into. So, if you have four requests, you'd put the responses into folers; "folder1" ... " folder4.". Then, when all the rresponse are back, (or you timed out), you can look at the folders in the tree to see what happened.

That only applied to V5, in V6 we keep the references in a queue. The exact implementation of the nodes should be irrevelant to your design (and is subject to change).

Thank you very much - greatly appreciated. I will do just that. Will give you feedback on it.
By the way, we also went for a presentation on the new features available in WBI v6 - awesome stuff. |

In the redbook "Developing solutions in WebSphere MQ Integrator" there is a chapter about the aggregate family nodes. The chapter should be enough to understand the way they work.
Best regards,
