Various PRM commands are mentioned in this chapter. See “Command reference” (page 101) for information on these commands.

Quick start to using PRM’s command-line interface

The following steps outline how to use PRM’s command-line interface. Detailed information on these topics is available in the remainder of the chapter.

1.Determine which configuration model you are going to use.

For information on planning your configuration, see “PRM configuration planning ” (page 37).

2.Create your configuration file. Use the prmloadconf command to create the default /etc/prmconf configuration file (if it is not present).

For help in determining the resource allocations in your initial configuration, see “Using prmanalyze to quickly identify resource use” on (page 42) .

3.Customize the configuration file manually in a text editor.

4.Check the syntax of the configuration file manually with -sor -c, as shown below. (The -cchecks are a subset of the -schecks.)

#prmconfig {-s -c} [-fconfigfile]

Use the -fconfigfile option to specify a file other than the default /etc/prmconf.

5.Load the configuration using one of the commands below:

To initialize, moving user processes to the owners’ initial groups and moving applications to their assigned groups, use the command:

#prmconfig -i [-fconfigfile]

To keep the existing assignments of users, processes, and groups, use the command:

#prmconfig -k [-fconfigfile]
