System Tracing Controls

The following parameters and commands for controlling system tracing are no longer supported and are replaced with other facilities in 18.0:

The SYSIDMS DB_TRACE_TABLE parameter is no longer supported. This parameter is replaced with the ADJUNCT_TRACE_TABLE parameter for consistency with new SYSGEN syntax.
The SYSGEN SYSTRACE ENTRIES parameter is replaced with a new SYSGEN and DCMT SNAP TASK parameter. For upward compatibility the system definition value for the new TRACE LIMIT parameter is set to the value of the deprecated SYSTRACE ENTRIES parameter.
The DCMT VARY SYSTRACE ENTRIES parameter is no longer supported. The size of the system trace table is now specified using the new DCMT VARY TRACE command.
The DCMT DISPLAY DBTRACE and DCMT VARY DBTRACE commands are no longer supported and have been replaced with the new DCMT DISPLAY TRACE and DCMT VARY TRACE commands.
