Like I mentioned before if you have 1 large process running it will not balance across the machines. If you have multiple pieces of integration going in, you should see it balancing across both machines.

I really can't comment more than what I have given you without looking into your environment and seeing the actual setup. In my opinion scalability is one of the most difficult things to setup in OTM and has taken me quite a while to compile a step by step guide for both active-active and active-failover. I would strongly recommend you logging an issue with Oracle support so that they can look into the issue for you.
