Hi,

I have the following situation:
The frontend system (SOAP over HTTP) performs Get request which consists of N ids. Then MB should perform N requests to backend system through MQ request queues. Backend system will then reply N times which should be aggregated into single SOAP response.

The N is unbounded. So the question is: How this can be implemented using Message Broker?

Thanks in advance,
Alexander

Hi mqjeff,

Thanks for reply!

As far as I know aggregation nodes do not support dynamic number of outputs. Actually I tried to use them but did not find out how I can setup number of messages to aggregate dynamically.

You could send the messages to MQ as a group. When you want to collect them on the MQ Input node, you can read them only when the group is complete.
