Communicating with ActiveMQ 5.2 from Oracle AS 10.1.3.4

First, I have to say this was a very frustrating task. This was for a customer project that requested we create a BPEL process in 10.1.3.4 that listens to a queue in Apache ActiveMQ 5.2. Naturally, I began with a Google search for someone else who's done this.

The search revealed 2 interesting posts: nabble.com, which appears to cover exactly what I need to do, and Oracle ActiveMQ JCA adapter with OC4J 10g How-to article, which is more geared for using the ActiveMQ JCA adapter from within a custom J2EE application. My preference is to set it up to use the JMS JCA adapter as a third party queueing provider rather than setting up a new resource adapter entirely, especially since I wasn't sure how to even setup a new resource adapter in OC4J outside of a custom J2EE application per the article above.

Performance Tuning Oracle BPEL

First, there are many sites that list some psuedo random steps that are related to performance tuning, but very few indicate why you should be doing them. While I can't answer why for all of them, I can provide the benefit of experience at least.
