I am very effective: (today anyway)

My problem is an overloading of the system during our month end processing. With CPU running at 100% I can see that tasks are sitting in IDMS waiting on EREECB. IDMS itself is getting good service but batch jobs are not responding after they are posted by IDMS.

I can see that the problem lies with too many initiators and too much other work running. We also have DB2 and various other services are competing for CPU.

Unfortunately IDMS is alwys the whipping boy because it is not from IBM and management perceive any problem in throughput as an IDMS problem. I am under pressure to come up with ""something"" even though I don't believe that IDMS is the actual problem.

I am not keen to reduce dataspaces or buffers to push IDMS into a more I/O bound situation because it performs exceptionally well 95% of the time. Our month end is the big killer.
