Comprehensive Command
and Control of Resources
From within NonStop NET/MASTER MS, users can control resources on both the
local system and other computers in a network. Users have secured access to these
management resources:
Distributed Systems Network Management (DSNM) commands, to manage the
state of token-oriented Tandem subsystems
DSNM commands, to communicate with conversational-mode Guardian utilities,
such as FUP and PUP, TACL macros, and custom utilities
Block-mode application programs, such as NetStatus, DSM/Problem Manager,
and Object Monitoring Facility (OMF)
Figure 1-2 illustrates the relationship between NonStop NET/MASTER MS and
DSNM.
When logged on to NonStop NET/MASTER MS, a user can start sessions with
Guardian utilities and application programs. A human user can enter the commands
from three different points:
An OCS window
The Command Entry screen
Within an NCL procedure
Every time a user starts a session by invoking an external utility, a message is sent to
the activity log. The activity log also receives a message whenever a user issues a
conversational-mode utility command. The activity log provides a historical record of
user activity. Using a command replacement feature, you can also write an NCL
procedure that traps specific commands issued by specific users and forwards
messages you specify to a real-time user activity monitor.
Access to conversational-mode utilities enables users to write NCL procedures that
invoke the utilities, provided the user’s command authority level permits access to the
utility and the specific commands invoked by the NCL procedure. For example, you
can write NCL procedures that use Guardian utilities to perform routine, after-hours
operations tasks. You can also use NCL procedures to automate object failure
recovery routines, based on interaction with Guardian utilities, DSNM commands, or
both.
