CICS system analysis

CICS® is a dynamic environment. Control tables and settings can be modified dynamically.

In maintaining the availability of CICS, it is helpful to view current control block entries and settings. In the CICS path, OMEGAMON for CICS (3270) displays control blocks, control tables, facilities, exits, parameter settings, and status indicators that are internal to the region.

Looking at the contents of internal control blocks and the usage of exits and internal facilities can help you to isolate system and application problems in CICS. For example, exits or control tables entries may be incorrectly defined, or there may be an excessive accumulation of: tasks on chains, temporary storage or transient data queues, dumps, or traces.
