Management With SCF
For example, to turn off the trace facility, enter the following SCF command:
-> TRACE PROCESS $GDSX, STOP
Methods 2 and 3 are of equal priority; they both override settings made with method 1.
Management With SCF
There are two management interfaces:
•
Interactive, conversational input by means of the Subsystem Control Facility (SCF)
•
Management programming control by means of a user-written management
application program that uses the Subsystem Programmatic Interface (SPI)
The interactive SCF interface includes commands used to configure and manage SU,
LINE, and GDSX objects; control the tracing facility; and display statistics on object
status and resource allocation. For general information about SCF functions and
command formats, see the Subsystem Control Facility (SCF) Reference Manual. For
detailed information on running SCF specifically to manage GDSX, see the SCF
Reference Manual for GDSX.
Summary information on managing GDSX is presented later in this section. You can
also add your own commands or modify attributes to extend the functions by
customizing the USER^ATTRIBUTES, USER^COMMANDS, and USER^REPLIES
user exits (see Section 9, “User Exit Descriptions,” for more information).
Use of the SPI interface to program customized subsystem management applications
or EMS filters requires some of the GDSX subsystem-specific token definitions and
EMS template definitions from the following files in the installed subvolume:
For more information about EMS template files, see the DSM Template Services
Manual.
