TRACE CONTROL - IBM Mainframe

The CICS trace Control program is a debugging aid. It provides information in Trace Table in response to CICS or trace control commands during the execution of the CICS transaction. The trace information is taken by CICS at each trace entry point. There are two types of trace entries viz. System trace entry points, which are automatically taken by the system at a command start time and completion time, and user trace entry points, which are taken by the application program through the ENTER command.
