Incompatible Sun Message Queue Version

I have been trying to scale a old Sun Access Manager deployment from 2 nodes to 4 nodes.

In trying to yield better performance, I made some minor upgrade to each dependent components. I knew that Sun Message Queue 4.x has better performance than the old 3.6 version.

So, I made a weird decision to deploy a hybrid of Sun Message Queues - 3.6 mixed with 4.4.

No good. You'll see this error in the MQ log during startup of AM SFO:



[29/Jun/2011:14:21:36 SGT] ERROR [B3098]: Configuration mismatch: Aborting connection with broker [ mq://10.10.10.15:7878/?instName=imqbroker&brokerSessionUID=null ] because following configuration properties do not match -

Update on 27th Jul 2011:


I realized hybrid deployment of Sun MQ works! In fact, the new deployment of different version of MQ has been running LIVE for a few weeks without any problem. (will continue to monitor though ...)
