One of the first requirements in solving a CICS® IA problem is to determine what type of problem you are experiencing.
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.
