Trace options

The valid options for use with this trace facility are shown in Table 1.

Table 1. Valid Trace Facility Options
Trace Event	Description
ENTRY	All module entries.
EXIT	Module exits with nonzero return codes only.
EXITA	All module exits.
CALL	Equivalent to specifying both ENTRY and EXIT.
UEXIT	Entries and exits of user exits.
RRTN	Entries and exits of recovery routines.
CB	Control block changes.
POST	Usage of certain MVS services.
SPECIAL	Entries and exits of commonly shared functions.
SUSP	Suspension or resumption of a work unit.
CONFIG	Configuration changes.
RLS1	Special purpose trace event for use under specific IBM® programming support direction.
RLS2	Special purpose trace event for use under specific IBM programming support direction.
RLS3	Special purpose trace event for use under specific IBM programming support direction.
RLS4	Special purpose trace event for use under specific IBM programming support direction.
RLS5	Special purpose trace event for use under specific IBM programming support direction.
DLKPD	Deadlock/timeout/retained-lock problem determination trace event.
COMP=(SMSVSAM)	Specifies all the functional areas of VSAM RLS component.
SUBCOMP=(component- list)	Specifies specific subcomponents within the VSAM RLS component.

The following terms are used to designate the subcomponents of VSAM RLS:

Note:

You may also specify ALL rather than list the COMP or SUBCOMP keywords.
COMP=(SMSVSAM) is equivalent to specifying ALL subcomponents. However, in most cases you would only trace the specific subcomponents.
The SUBCOMP keyword can be specified without the COMP keyword.
Any of these options, except for ALL, COMP, and SUBCOMP, can be turned off by prefixing them with NO (for example, NOVOC, NOSLCH).

The following command will turn off the trace facility:

TRACE CT,OFF,COMP=SYSSMS

Here are some examples of typical replies to activating SMS trace:

To trace record management entry/exit

    R XX,OPTIONS=(ENTRY,EXITA,SUBCOMP=(VRM)),WTR=CTWDASD,END

To trace deadlock/timeout problem determination information
```
    R XX,OPTIONS=(DLKPD,SUBCOMP=(VRM)),WTR=CTWDASD,END
```
If special trace code were provided for RLS1, the following would be recommended by IBM programming support to utilize that special trace code:
```
    R XX,OPTIONS=(RLS1,SUBCOMP=(VRM)),WTR=CTWDASD,END
```
