CICS can experience two types of abnormal ends-abends that affect
one-transaction and abends that affect CICS itself.
CICS transaction and system dumps should be produced for use in the debugging process. The CSMT Log, produced when CICS is brought down, can also be useful.
The CICS Statistics Report is produced when CICS is brought down. Statistics shown include task control, storage, transactions, programs, dumps, and temporary storage. This report can be valuable in identifying what happened to CICS when a problem was encountered.
For more information, see the IBM documentation for CICS Transaction Server.
If you are serious about improving the performance of your CICS production environments, you should be running your CA Ideal programs in load module format.
Load modules provide performance benefits and an additional means of monitoring and tuning your environment. Using load modules can also reduce the impact on your system of migrating production applications.
