I have an mdb on a was server with an inbound queue and reply queue. What would be the best way to go about testing the durability of the MDB

like what tool do you guys use to stress test/perf test

Also,

What is the best ways for me to try to break it, like send funky data/headers to have it test the whole REQUEUE Backout queue process.

thanks for the advice

You should have some kind of logic in your MDB to test for a message you "don't understand". Whatever this is, you can use amqsput (or something similar) to put this kind of message. Your program should rollback the message and it should eventually get to the backout queue.

as far as stressing it goes I find the only way is to simply see how fast it can consume messages., but I'm sure there are some proper tools that you can pay for. I use logging and the PMI metrics from WAS to do analysis on this. The metrics are actually quite good!

To test the backout deal, I use RuntimeExceptions that I throw these based on logic in the MDB itself. These are useful because they are unchecked/checked - whatever way round it is, so that you do not have to delare it in the method throws clause, or catch it in a try/catch, just like exceptions that you don't expect.
