Hello,
I have some problem with an aggregate node. In my context i want to use this node to manage a timeout on the reply from one application.
To start the timeout, i generate a dataflows to simulate the call to a second application.
In the reply data flow (i split the fan in and the fan out), i have two problems : the timeout doesn't work (reponse =10s, timeout=2s) and the simulated response from the dataflow always generate answer in the out terminal. I don't know what i do wrong.
Other question about aggregate node : how can i found source code for taxi/hotel example. I have a problem of duplicate msgid behind the aggregatecontrol. I generate a new msgId for one entry but i don't know if it's the good way .
Thank for your answer and sorry for my poor english

Philippe,
Make sure you are setting timeout value properly for reply messages. This property must be set on AggregateControl node.
I don't think there is any source code for taxi/hotel example. However, Chapter 6 in Using Control Center book talks about this example.

Hi,
I set, i think, correct value for timeout in Aggregate control. In the control center, they don't speak about the code in compute node before posting request in taxi & hotel queue. I think i need something special in one of the compute node, to manage the duplication of the msgid.
Do you know what is the code in these compute nodes ??
Thx

Hi,
There is an IBM Redbook - sg246579 - Developing Solutions in WMQI that has a chapter about the Aggregator family nodes (chapter 6).
This might be of interest.
Best regards Mapa

| the code in the compute nodes can be anything....it can be a logic to generate reservation for taxi and hotel. i just added a tag to my xml and generated the headers so that the agg reply reads it and puts it as xml instead of BLOB. but just make sure you donot loose the local destination list as this is required by the agg request and reply resp. you can put your code to duplicate the ids in the compute node, but before the output reply node. |

Hi
Thanks for the red book with more details about aggregate node implementation.
But i alway have a problem with msgid duplication (and so it can't write in the database references about requests) => In compute nodes before output, I duplicate the message (set OutputRoot = InputRoot) and the LocalEnvironement AggregateNode informations. Is it necessary to generate a new Id or is it a problem with my configuration or my implementation (i have a request on a distant server and one with internal dataflow)
Thx for your help

Also an aggregation example (in my opinion better, but then I did write it) in another redbook. You can download the flows etc as well.

My appologies Zpat, didn't remember that book too talked about aggregation.
I haven't tried to use aggregation yet, so I hope that excuses me

You can do this by designing multistage processing flows. In first stage store messages into Database. When last message arrvies, trigger second stage message flow. This message flow will read all messages belonging to this group from DB and creates single output message.
