MQ Prorgamming with Java - Improving Performance

Hi - We are in the process of writing a Java component that would read from an MQ. This Q would get around 20K messages per hour. Our Java program needs to read this Q, parse the data and process it.

Are there any guidelines/ performance improving techniques while programming Java with MQ for Txns of this volume ? Any tips or pointers to sites containing MQ Java tuning techniques would be helpful. Thanks

What's an "MQ"?

For that matter, while I can guess, what's a "Q" and a "Txn"?

Try IBM developerworks site. It woudl have the complete spec of the mq api. and also a couple of red books on performance. But dont expect too much. 20K mesages should be pretty fine..Keep doing memory profiling to fine tune.

Assigning a separate Thread to each message read might be a good idea, that way any hold-ups in message processing would not cause a buildup of messages in the queue.

A queue send/receive model enables better parallelism; so you are in the right track. to scale the processing; simply increase the instances of the queue receiver. have 10-12 threads/ JVM and have 1-3 JVM.

In your case is you need to process 20,000 messages / hour i.e.
Per second processing 20,000/3600 = 6
suppose your processing per transaction takes 1 second; all you need is 6 threads and one JMV. But in reality based on complexity of your message you should be taking less than one sec.
