Trace options are normally set using appropriate sysparms. The TO function of UUTIL enables the system programmer to modify some of these options online. However, any changes made with the TO function are only active for the duration of the current Com-plete run. When Com-plete is restarted, the values as set in the sysparms are in force again.
If you select the TO option from the utilities menu, the trace maintenance screen is displayed, for example:
16:45:58 TID 5 COM-5.1. User ID MBE 12.11.97

The various trace classes can be set by typing Y(on)N(off) against the listed trace classes and pressing . The traces can be restricted to a specific TIB if its TIB number is specified in the corresponding field.
A DD statement for SYSTRACE must be present in the startup JCL if the extended APPC trace is to be opened. Note that the otion field will contain "O" if the trace file is open, 'Y' if open was requested (but not completed) and "N" if the file is closed. For more details refer to System Programming documentation section VTAM Interface.
A message is written to the operator console for each modification made to this screen indicating the changes, userID and TID number of the user that made the changes.
