CICS dump and traces

CICS dumps and traces are an important source of detailed information about problems.

Stabilized feature: Service Flow Runtime and Service Flow Modeler capability in IBM Developer for z/OS 14.2.3 are stabilized. Consider exposing and orchestrating applications as API services by using z/OS Connect Enterprise Edition, CICS web services, or by writing web applications in Java or Node.js. See also Stabilization notices.

Whether they are the result of an abend or a user request, dumps allow you to see a snapshot of what was happening in CICS at the moment the dump is taken. However, because they do provide a snapshot, you might need to use them with other sources of information relating to a longer period of time, such as logs, traces, and statistics.

For information about the dump formatting keywords used to extract BTS information from a CICS system dump, see Using dumps in problem determination.

CICS also provides tracing that enables you to trace transactions through the CICS components and service flow programs.
