CTRACE_DEFAULT_OR_MIN

Description:

Checks to see whether any component traces have been active with other than the default and the minimum for longer than the threshold.

Reason for check:

A component trace that is tracing more than the default can cause degraded system performance.

z/OS® releases the check applies to:

z/OS V2R2.

Type of check (local, remote, or REXX):

Local

User override of IBM values:

The following sample shows the defaults for customizable values for this check. Use this sample to make permanent check customizations in an HZSPRMxx parmlib member used at IBM Health Checker for z/OS startup. If you just want a one-time only update to the check defaults, omit the first line (ADDREPLACE POLICY) and use the UPDATE statement on a MODIFY hzsproc command. Note that using non-POLICY UPDATEs in HZSPRMxx can lead to unexpected results and is therefore not recommended. End of change

Debug support:

Verbose support:

Yes. When Verbose(Yes) is in effect, all component traces using other than the default are displayed, even if they have not reached the threshold.

Parameters accepted:

Yes, the following parameters are accepted:

TIME(DAYS,n) or
TIME(HOURS,n).

Each of which identifies the length of time that any component traces must be active with options that are not the minimum and not the default before the exception is raised. “n” may range from 1-9999
