The trace facility can be activated by the operator TRACE command, or 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 on using CTncccxx to specify tracing options, see "CTncccxx" in z/OS MVS Initialization and Tuning Reference.
The syntax of the TRACE command for tracing the PDSE component is:
Command | Keywords |
---|---|
TRACE | ,WTRSTART=membername [WRAP|NOWRAP ] ] ] |
CT [,WTRSTOP=jobname ] ] | |
[CT [,ON ] { {COMP=SYSSMS } [,SUB=(sub[sub],...)] | |
[,PARM=CTISMSxx] } ] | |
[CT [,nnnK ] { } ] | |
[CT [,nnnnM] { } ] | |
[CT [,OFF] { } ] |
The default SYSSMS trace table size is 72 KB.
PARM=CTISMSxx identifies the SYS1.PARMLIB member that contains the tracing options.
The nnnK and nnnnM keywords can be used to specify trace table sizes of 16–999 KB or 1–2047 MB, respectively.
Command | Keywords |
---|---|
REPLY | id |
[,JOBNAME=(jobnamelist)] | |
ASID[,=(asidlist.)] | |
[,OPTIONS=(namename...)] | |
[,WTR=procname|DISCONNECT] | |
[,END] |
The TRACE and REPLY commands are fully described in z/OS MVS System Commands.
