MQSeries or messaging simple question

Dear people,
I have long known people would use MQSeries to do asynchrounous messaging. But, I read some solution out there which uses it for synchronous as well.
Question is, does MQSeries really does synchronous messaging?
What are the principle behind people choosing messaging with synchronous behaviour?
Thanks.


Thank you.<br /> <br />- Jess Sie<br /> <a href="mailto:jess@see-consulting.com" rel="nofollow">jess@see-consulting.com</a>

Using MQSeries for Synchronous Processing.
It does "almost synchronous" messaging. You would choose this if you need time-dependant responses, as opposed to "ask now get the answer later".

Hmmm, I thought synchronous MQ was as simple as using the getAndWait() API to wait for the message to come back and pull it off the queue. We use this on an app server where the client thinks it is calling a synchronous service. We have to wait for the MQ response before we return to the client. I've always had a wrapper around MQ, not really written to the MQ API mice elf.
We use MQ as synchronous and asynchronous RPC, which is not usually a problem that suggests MQ as an answer. But after some effort we got outstanding performance and reliability out of MQ.


A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
