Hi,
If a message flow is monitoring 3 input queues and picks up a message from queue1, is it able to begin processing a subsequent message that arrives at a different queue....or does it have to finish processing the message it picked up from queue1 before it can process the message on queue2?
thx

| In General A Message flow processes one message at a time.If you need to process all the messages coming in to three queues at a time.all you need is to deply the message flow in three different execution groups. |

Well, first of all, you don't need to deploy to three separate execution groups to get parallel processing. You can merely increase the number of instances of the message flow in the one execution group.
Secondly, things get interesting when there are more than one MQInput node in the same flow. The message flow automatically gets extra instances, one for each additional MQInput node.
But, third, none of this will allow you to aggregate messages from three input queues. For that, you need to either use the MQGet node (a plugin), or use the aggregation nodes.
