Hi Denis, Thanks for your response. I'm not trying to write my own transaction manager rather I'm hoping to use RRS in that role, after all RRS is already being used for DB2 access. Now if Java does not provide any means of using RRS to coordinate multiple resources I guess I'm out of luck. I'll probably have to use DB2 provided functions to write to MQ. BTW we do have batch cobol programs at our site that access both DB2 and MQ though that's all I know about them. May be these programs have their own transaction management code but I find it very odd that these would not be transactionally sound. But who knows, reality is not limited by anyone's ability to conceive it. As for using an environment other that batch, this process was implemented in WAS/z but the cpu consumption killed the project. I don't know how much of that was WAS overhead and how much was due to the application code. My batch Java code does everything except for writing one message to MQ for about a fourth of the cost. Does Spring offer some kind of transactional facility ? I thought it was just a sql generator. Regards Mohammad
