by the SYSPARMS CMDREPL command. The searching during the preloading phase
follows the NCL procedure library search path described in Section 3, “Configuring
NonStop NET/MASTER MS.” To view a list of NCL procedures loaded by the
CMDREPL command, issue the SHOW PRELOAD command discussed under
“Viewing Information About Preloaded NCL Procedures,” later in this section.
Defining Default
Function Keys
NonStop NET/MASTER MS supports up to 32 function keys, depending on the type
of terminal. You can define function keys for both Tandem 6530 or compatible
terminals and IBM 3270 or compatible terminals. Each function key can be customized
either for an individual or system-wide. The INIT NCL procedure defines the
system-wide, or global, command or commands invoked when a function key is
pressed.
To define a global function key, change the INIT NCL procedure to include FK or PF
commands that define the key. Use the FK command to define a function key for
Tandem 6530 or compatible terminals. Use the PF command when you define a
function key for IBM 3270 or compatible terminals only. The following example, when
included in the INIT NCL procedure, enables all users to issue the SWAP command by
pressing F9:
CMD "FK F9 IMM,SWAP"
Users authorized to invoke the FK or the PF command can override the global function
key definitions and define local function keys, which apply only to the user who
issued the FK command. For additional information, refer to the NonStop
NET/MASTER MS Operator’s Guide.
Limiting Use of
System Resources
During peak processing periods, you might need to reduce the amount of system
resources that operators can consume. NonStop NET/MASTER MS enables you to
control many features that influence the amount of resources an operator can use.
Limiting the Number of
Concurrent Users
Use the MAXUSERS command to view or restrict the maximum number of users that
can log on to NonStop NET/MASTER MS concurrently. Such a command can be
helpful in reducing system use during peak processing hours. The command takes
effect immediately for new logons, but no current users are logged off forcibly.
Entering the command with no argument shows both the current limit and the
number of users currently logged on.
MAXUSERS
NNM0662 CURRENT MAXUSERS LIMIT IS 500, NUMBER OF USERS IS 219
To limit the number of concurrent users, supply an argument with the command. For
example, to limit the number of concurrent users to 300 users, issue the command
shown here:
MAXUSERS 300
Valid arguments include integers from 0 through 9999.
