The response to the command is returned to NonStop NET/MASTER MS, which
does the following:
Displays the response to the FUP INFO command on the user’s terminal
screen
Sends the response to the FUP INFO command to the NonStop
NET/MASTER MS activity log
Although you can allow users to start conversational-mode utilities with the
PROGRUN command, there are important advantages to encouraging use of the
OPSYS command instead. Firstly, when a user starts an external utility with the
OPSYS command, the utility sends the results, such as response messages, of the
session to NonStop NET/MASTER MS. Therefore, an NCL procedure that uses
OPSYS commands can work with an external utility to perform these tasks:
Start a session with an external utility
Issue external utility commands
Receive and analyze the results of utility command processing
Act on the results
Secondly, you can assign a separate command authority level to every
conversational-mode utility command. For example, you can assign a relatively low
level to informative commands, such as the PUP LISTDEV command, and a relatively
high level to potentially disruptive commands, such as the PUP DOWN command.
Thirdly, use of utilities accessed by the OPSYS command can be monitored by looking
in the activity log. As noted earlier, when a user starts a utility with the OPSYS
command, all commands and responses are logged in the activity log.
Using the OPSYS
Command to Execute
DSNM Subsystem
Commands
Users execute Distributed Systems Network Management (DSNM) commands, which
are used to control subsystems in a network, by using the OPSYS command. The
SYSPARMS SWGUIDDSNM command determines the Guardian user ID (GUID) used
to execute the command. If the setting of SYSPARMS SWGUIDDSNM is YES,
NonStop NET/MASTER MS executes the DSNM command using the current GUID of
the user executing the command (the PROFILE GUID command allows a user to
switch from one permissible GUID to another). If the setting of SYSPARMS
SWGUIDDSNM is NO, NonStop NET/MASTER MS executes the DSNM command
using the GUID of NonStop NET/MASTER MS.
Refer to the NonStop NET/MASTER MS Command Reference Manual for more
information about the OPSYS command.
