Trace destinations

You can choose from any number of the destinations for the trace entries produced by CICS. Any combination of these destinations can be active at any time.

• The internal trace table
• The auxiliary trace data sets
• The MVS™ generalized trace facility (GTF) data sets
• The JVM server trace file in z/OS® Unix System Services

You can choose the most appropriate trace destinations based on their characteristics, the amount of trace data that you need to capture, and whether you want to integrate CICS tracing with tracing done by other programs. The JVM server trace file is unique to each JVM server. For more information on this trace file, see Troubleshooting Java applications.

You can control the status and certain other attributes of the trace destinations either while CICS is running, or by specifying system initialization parameters at CICS startup. For instructions to control the trace destinations, see Setting trace destinations and tracing status.
