What do you think about Tibco EMS Explicit acknowledge mode?

Hi,

I'd like to know if you have any thoughts about Tibco EMS Explicit acknowledge mode. What are disadvantages, known problems etc. if there are any? I've read all the documentation about it and I have some concerns.

TIBCO EMS Explicit Client Acknowledge — (only available for TIBCO EMS) the message will be acknowledged at a later point by using the Confirm activity. The session is not blocked and one session handles all incoming messages for each process instance. If a message is not confirmed before the process instance ends, all messages received in the same session are redelivered.

How big is this session? Does the size of this session depend on FlowLimit or something like this? Do you know of any problems with this ACK mode and enabled flowControl on EMS?

Thanks in advance,

Maciej
