Dedicating Terminals Operators use NonStop NET/MASTER MS from dedicated terminals. A dedicated
terminal is a terminal at which NonStop NET/MASTER MS controls the logon dialog.
When switched on, a dedicated terminal displays the NonStop NET/MASTER MS
logon screen instead of some other logon command entry prompt, such as a TACL
prompt. The dedicated terminal thus enables NonStop NET/MASTER MS to control
the range of options a user can perform at the terminal. You can also monitor and
temporarily cut off access to dedicated terminals.
Adding a Dedicated
Terminal
Before you dedicate a terminal to NonStop NET/MASTER MS, stop every process that
is using the terminal, such as the terminal’s TACL process. Then, use the TERMINAL
ADD command to define a dedicated NonStop NET/MASTER MS terminal. The
command takes the following form:
TERMINAL ADD= logical-name DEVICE= device-name
Use the logical-name argument to assign a logical name to the terminal. Most
NonStop NET/MASTER MS commands applied to terminals accept the logical name
as an argument. The device name is the name of the terminal that you are dedicating
to NonStop NET/MASTER MS. For example if you wanted to define terminal
$T500.#TRM4 and give the logical name TERM2, enter the following command:
TERMINAL ADD=TERM2 DEVICE=$T500.#TRM4
You can define a terminal during the startup phase by including a TERMINAL ADD
command in the INIT or READY NCL procedure.
Suppose you want to configure your system so that it defines four dedicated NonStop
NET/MASTER MS terminals during the system startup phase. The terminals are
named $T014, $T015, $T023, and $T153. To define the terminals, include these
commands in the INIT NCL procedure:
CMD "TERMINAL ADD=OPER01 DEVICE=$T014"
CMD "TERMINAL ADD=OPER02 DEVICE=$T015"
CMD "TERMINAL ADD=OPER03 DEVICE=$T023"
CMD "TERMINAL ADD=OPER04 DEVICE=$T153"
One useful approach might be to create a separate NCL procedure, perhaps called
TERMADD, that contains all of the commands for defining the terminals you want to
dedicate. Then, include a line in the INIT procedure that calls TERMADD.
Starting a Dedicated
Terminal
Dedicated terminals are available only after you start them. Use the OPENTERM
command to start a dedicated terminal. For example, issue the following command to
start a dedicated terminal whose logical name is TERM2:
OPENTERM TERM2
If terminals are defined during the startup phase, consider issuing the OPENTERM
command in the INIT or READY NCL procedure to start the terminals. This statement
starts all defined dedicated terminals:
CMD "OPENTERM ALL"
The command applies only to defined dedicated terminals.
