Hi
Is someone try to use WMQI to rout & transform question and answer between two applications. Is it easy to manage timeout and error through a system like this one which is asynchronous (to simulate synchronous mode). If yes, can i find some example to manage this ?
Thanks

It is possible to design an application using WMQI which does transformation and routing of messages (question Answers/Request Reply) for you.
You will also need some MQ application (Adapter) which maps request to reply for you. Your application can take care of error handling and timeout.
I don't think there is any supportpac, which talks about these examples. You could start designing your application and post questions here if you have any problem.
Good luck!

The point to remember is that WMQI does not wait for replies - your requesting application does.
Requestor -> message -> WMQI -> message -> Server
and then
Requestor <- message <- WMQI <- message <- Server
WMQI does not call the server and wait for a response. It merely transforms and routes MQSeries messages on the way.
If the server is not MQ enabled, then you could call it from a WMQI plugin node and wait for a response, but this is not ideal.

Hi,
I hear about aggregate node which permits to wait an answer with a timeout control on the response. Is it a possible solution or it's not a good solution for this kind of architecture.
Thanks.

If you are expecting multiple small requests in a single request message, which needs to be processed by different backend/server programs then you can make use of Aggregate functionality.
