NCL and Major NonStop NET/MASTER MS Services
Introduction to NCL
1–2 106160 Tandem Computers Incorporated
User ID Management
Services (UMS)
UMS is the NonStop NET/MASTER MS security service that enables the definition of
authorized NonStop NET/MASTER MS users and their associated functions and
privileges. UMS gives you the authority to use services of NonStop NET/MASTER
MS. It enables, for example, access to OCS and Edit Services. It also lets you define
the name of the subvolume in which you store NCL procedures, NCL object files, and
panel description files.
You can access the UMS database from NCL. You can retrieve, check, and change
UMS information from an NCL procedure.
If your installation is not using UMS as the security system to maintain user ID
information, but is using its own security system, you can use NCL to gather
information from it and to pass it to UMS.
For more information on UMS, refer to the NonStop NET/MASTER MS Operator’s Guide
and the NonStop NET/MASTER MS System Management Guide.
Inter-NET/MASTER
Connection (INMC)
INMC is the NonStop NET/MASTER MS service that allows multiple NonStop
NET/MASTER MS and the SOLVE management services systems to be connected and
controlled from one location.
If you have many INMC links with other systems, then you need to use many
NonStop NET/MASTER MS commands to define and start these links. You can write
an NCL procedure to do so automatically at NonStop NET/MASTER MS startup.
In addition, you can write an NCL procedure to continuously monitor the status of all
links. You can instruct the NCL procedure to report if any links fail and to
automatically attempt to restart them. The NCL procedure can report the results of its
attempts in the OCS message display area.
For more information on INMC, refer to the NonStop NET/MASTER MS Operator’s
Guide and the NonStop NET/MASTER MS System Management Guide.
Remote Operator Control
(ROC)
ROC is the NonStop NET/MASTER MS service that allows users to log on from a local
NonStop NET/MASTER MS system to a remote NonStop NET/MASTER MS or a
SOLVE management services system, to execute commands on the remote system, and
to receive the results at the local NonStop NET/MASTER MS system.
Results from commands entered in OCS are displayed in the OCS message display
area at the local system. Results from commands issued by an NCL process can be
sent to the NCL process for analysis.
For more information on ROC, refer to the NonStop NET/MASTER MS Operator’s Guide
and the NonStop NET/MASTER MS System Management Guide.
Inter-System Routing (ISR) ISR is the NonStop NET/MASTER MS service that enables, disables, and controls
system-level message flows between multiple NonStop NET/MASTER MS and the
SOLVE management services systems.
EMSPROC is the major system-level NCL procedure that gathers messages from
remote systems according to the established ISR definitions. You can write your own
