Classifying the problem
One of the first requirements in solving a CICS® IA problem is to determine what type of problem you are experiencing.
Problems can be classified into the following areas:
- Incorrect output or unexpected results
- Waits or hangs
- High CPU usage, perhaps caused by looping
Problems involving incorrect output or unexpected results can sometimes be the most difficult problems to solve. If you can re-create the problem, activating various levels of tracing usually provides IBM® support personnel with sufficient information to solve the problem.
If the problem is a wait or hang, or high CPU usage on the CICS IA server, IBM support personnel might require a dump of the CICS IA address space.
