NonStop NET/MASTER MS Commands

PARAM The PARAM command defines NonStop NET/MASTER MS startup parameters or
changes certain startup parameters. Startup parameters contain settings used during
NonStop NET/MASTER MS startup, before execution of the INIT NCL procedure.
Startup parameters contain settings for:
The locations of certain NonStop NET/MASTER MS files
The names of certain NonStop NET/MASTER MS files
NonStop NET/MASTER MS process types and process attributes
PARAM commands are normally executed during NonStop NET/MASTER MS
startup in the NonStop NET/MASTER MS configuration file. This file is used when
you want to start a customized version of NonStop NET/MASTER MS. The file is
used when the NonStop NET/MASTER MS control process (NCP) object file is run
from TACL, when NonStop NET/MASTER MS is executed and initialized.
You can create a configuration file or modify an existing configuration file using PS
Text Edit (Tedit). Each PARAM command must begin on a new line in the
configuration file (to be recognized, PARAM must be the first word on a line). You
can include comments in the configuration file by beginning a line with two equal
signs (==). Tedit restricts line length to 239 characters.
You specify the name of the configuration file in the RUN command used to execute
NonStop NET/MASTER MS from TACL. The NCP reads the configuration file and
stores the information. The configuration file is not used after NonStop
NET/MASTER MS starts up.
Some PARAM commands configure a single value, such as the domain ID of the
system; these should occur once only in the configuration file (because the last value
set in the configuration file supersedes all other values). Some PARAM commands
add information to a list, such as a list of the central processing units, which are
available for use by NonStop NET/MASTER MS; these can occur more than once in
the configuration file. Other PARAM commands define and name processes, such as
dynamic, global memory manager (GMM), and static processes; these must occur in a
group, and you can include multiple process definition groups in the configuration
file.
You can modify the value of only one startup parameter after NonStop NET/MASTER
MS startup using the PARAM command: CPUWEIGHT, which specifies and changes
the relative weight allocated to a central processing unit (CPU). When used after
NonStop NET/MASTER MS startup, the default authority level of the PARAM
command is 4. The CPUWEIGHT operand has a default authority level of 9. You can
enter this command from any NCL procedure, including the INIT NCL procedure, by
using either the CMD core statement or the INTCMD verb. (Using the PROCESS
ALTER command, you can modify other startup parameters. See the description of
these commands for more information.)
The SHOW PARAM and SHOW PROCESS commands list the operands of the
PARAM command about which you can obtain information.
