Tracing in the CICS VR server address space

DFSMSdfp provides a trace service for use with CICS® VR server. A special trace table is created in CICS VR server address space and in each address space where CICS VR client applications are run and tracing is selected.

You can use the SYS1.PARMLIB member CTncccxx to specify trace options for the TRACE CT command and to turn off tracing. CTncccxx must exist at IPL for tracing to be available on the system. The default is CTISMS00. For more information about using CTncccxx to specify tracing options, see "CTncccxx" in z/OS MVS Initialization and Tuning Reference.

Trace also allows external writers (WTR) to capture trace buffers. Capturing trace buffers increases diagnostic capability and decreases the possibility of losing trace data.

Complete syntax and usage information for TRACE can be found in z/OS® MVS™ System Commands.

Here is an example of the CTncccxx member for CICS VR server component trace:

TRACEOPTS ON
OPTIONS('ENTRY,EXIT,CVR1,COMP(CICS VR),SUBCOMP(NOVRLL)')
