The Operations Layer
•
User ID Management Services (UMS), a security service that enables the definition
of authorized NonStop NET/MASTER MS users and their associated functions and
privileges.
•
Inter-NET/MASTER Connection (INMC), which allows multiple NonStop
NET/MASTER MS and SOLVE management services systems to be connected and
controlled from one location.
•
Remote Operator Control (ROC), which allows users to log on from a local NonStop
NET/MASTER MS system to a remote NonStop NET/MASTER MS or SOLVE
management services system, to execute commands on the remote system, and to
receive the results at the local NonStop NET/MASTER MS system.
•
Inter-System Routing (ISR), which enables, disables, and controls system-level
message flows between multiple NonStop NET/MASTER MS and SOLVE
management services systems.
NetCommand
NetCommand is a command-line interface to DSNM. NetCommand is composed of the
following:
•
The NetCommand configuration file (NETCONF), which contains the following
information about the NetCommand environment:
•
The log file and limit on the length of log entries.
•
The name of the DSNM command server process (discussed under “The
Management Services Layer” on page 1-8).
•
The name of the NetStatus terminal start server process (discussed under
“NetStatus” on page 1-4).
•
The command sets for specified groups of users and terminals.
•
The node access restrictions for specified groups of users and terminals.
•
Default NetStatus display sets for specified groups of users and terminals.
•
A TACL requester process (NETCMD), which:
•
Defines the user environment (such as the operator’s command set, what nodes
the operator can control, and the number of response lines logged).
•
Secures DSNM by checking each command against the user environment.
•
Executes TACL commands entered by the user or received from NetStatus.
•
Passes DSNM commands to the NetCommand server process.
•
TAL-based NetCommand server process (NETSVR), which:
•
Parse DSNM commands into tokenized form.
•
Pass control and status commands to DSNM.
•
Invoke utilities.
