11.7. CICS trace control facility
CICS exception tracing is always done by CICS when it detects an exception condition. The sorts of exception that might be detected include bad parameters on a domain call, and any abnormal response from a called routine. The aim is first failure data capture, to record data that might be relevant to the exception as soon as possible after it has been detected. The trace options can be set using the CICS/ESA® Trace Control Facility (CETR) transaction. This will enable you to increase the trace table size and let you control CICS component (domain) trace options. Tracing for all CICS components should be set to level 1 when collecting diagnostic data.
You can also write out CICS trace data to a disk data set ...
