This parameter is optional. If the specified PARMLIB member is incorrect or absent, ICSF CTRACE will attempt to use the default CTICSF00 PARMLIB member. If the CTICSF00 PARMLIB member is incorrect or absent, ICSF CTRACE will perform tracing using an internal default set of trace options. By default, ICSF CTRACE support will trace with the KdsIO, CardIO, and SysCall filters using a 2M buffer. For more information refer to Creating an ICSF CTRACE configuration data set.
If a cryptographic processor is available, the DOMAIN parameter is required if more than one domain is specified as the usage domain on the PR/SM panels. If a cryptographic processor is not available or only one usage domain is assigned to the LPAR, the DOMAIN parameter is optional.
