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 respo=
nding 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 fo=
r 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 und=
er pressure to come up with ""something"" even though I don't believe that ID=
MS 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.
