The CONFIG File
Configuring NonStop NET/MASTER MS
3–2 115414 NonStop NET/MASTER MS System Management Guide
The Purpose of the CONFIG
File
The CONFIG file sets and changes startup parameters. Use the CONFIG file to
override the default startup configuration of the processing environment and establish
alternative locations of important files. Using a CONFIG file, you can:
Enhance system performance by defining multiple occurrences of heavily used
processes
Change the execution attributes—such as name, priority, and CPU assignment—of
processes
Designate the relative availability of CPUs for dynamically created processes
Deactivate NonStop NET/MASTER MS components that support remote
operations
Disable access to Guardian user IDs (GUIDs) other than that of the NonStop
NET/MASTER MS system
Specify changes in the locations of program files or NCL procedure libraries
Integrate NonStop NET/MASTER MS with an externally started DSNM system
The Distributed CONFIG
File
Tandem distributes a sample CONFIG file, called ZCONFIG, in the ZNNMDATA
subvolume that you can copy and modify. See Appendix C, “Sample CONFIG File
Segments,” for examples of CONFIG files.
Creating and Using a
Customized CONFIG File
You can create a CONFIG file with a text editor because a CONFIG file is simply an
edit file that consists of one or more PARAM commands. You can access a text editor,
such as PS Text Edit (TEDIT), from within NonStop NET/MASTER MS by using the
PROGRUN command or Edit Services.
Unless instructed to do otherwise, NonStop NET/MASTER MS uses the default
startup configuration. Therefore, you need not specify a value for each PARAM
command operand. Include commands only for the operands whose values you want
to override. An important exception to this rule is definition of processes and their
configuration. A complete list of PARAM command operands appears in the NonStop
NET/MASTER MS Command Reference Manual.
A CONFIG file is used when its name is specified as a startup parameter of the NCP
program. Section 2, “Starting NonStop NET/MASTER MS,” describes the NCP
program startup parameters.
NonStop NET/MASTER MS does not start if any of the following CONFIG file-related
errors occur:
The CONFIG file contains a syntax error
The NonStop NET/MASTER MS control process (NCP) cannot find the CONFIG
file
The NCP cannot read the CONFIG file
