CSTCP_SYSTCPIP_CTRACE_tcpipstackname

Description:

Checks if TCP/IP Event Trace (SYSTCPIP) is active with options other than the default options (MINIMUM, INIT, OPCMDS, or OPMSGS). The tcpipstackname suffix is the job name of the TCP/IP stack to which this check applies. Use CSTCP_SYSTCPIP_CTRACE_* to reference this check for all stacks.

Reason for check:

If problem documentation is not being gathered, only the default SYSTCPIP trace options (MINIMUM, INIT, OPCMDS, or OPMSGS) should be active. Leaving other options active can result in performance degradation.

z/OS® releases the check applies to:

z/OS V1R8 and later.

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
