Would anyone please happen to have good resources for using JMS over Ibm's MQ implementation ?
I've just started using JMS over MQ. I've read through 3 IBM redbooks on the subject, copied their "hello world" examples, and they basically work. But sadly I've found no documentatino on real-world problems, and performaces in particular. Some random Examples:
1. Transactions affect on performance. Eg: suppose you post a 1000 large messages, all under the same transaction. Obviously they need to queue up somewhere - but where: the sender machine or the receiver ?
2. Is it true there's a performance problem when a Receiver uses a selector ? I hear it works well if you select by MessageId , but performance deteriorates if the selector is based on user-defined properties.
These are just examples - the bottom line being, you can't just rely on the pure JMS spec... implementation details could be important. Would anyone have recommendations on relevant resources ?
