SYSTRACE

Description:

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

Reason for check:

A mode trace runs continuously, so an active unneeded MODE=ON option can cause degraded system performance. Use mode tracing only for short periods of time to solve a specific problem and do not use mode tracing as the default for system tracing on your system. MODE=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
