SYSTRACE_BRANCH

Description:

Checks to see whether system trace is using the BR=ON parameter of the TRACE command and has been active for a longer time than the defined duration.

Reason for check:

A branch trace runs continuously so an active unneeded BRANCH=ON option can cause degraded system performance. Use branch tracing only for short periods of time to solve a specific problem and do not use branch tracing as the default for system tracing on your system. BR=ON is intended for use in system software problem determination and diagnosis situations only.

z/OS® releases the check applies to:

z/OS V2R1 and later.

Type of check (local or remote):

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
