IBM-supplied default for GTFPARM

When GTF is started by specifying the IBM-supplied cataloged procedure, the following options exist in GTFPARM:

TRACE=SYSM,USR,TRC,DSP,PCI,SRM

These keywords cause the following events to be recorded: SVC interruptions, I/O interruptions, program-controlled I/O (PCI) interruptions, program interruptions, external interruptions, dispatcher executions, start subchannel and resume subchannel operations, clear subchannel operations, halt subchannel operations, modify subchannel operations, entries to the system resource manager, entries to recovery routines, events associated with GTF (TRC), and data passed to GTF via the GTRACE macro (USR). All keywords except USR result in minimal format trace entries. USR entries are the length specified by the user in the GTRACE macro. Such entries may optionally be a maximum of 8192 bytes, excluding the prefix.

Note: If you use the default options provided, be aware that some data will be duplicated by the system trace if it is executing concurrently with GTF.
