2.Remove the line corresponding to the application record you wish to remove. Application records have the following form:

APPLICATION::::GROUP[,ALT_NAME[,...,ALT_NAME]]

NOTE: You may have multiple records for a single application. Be sure to locate all records for an application in the configuration file and remove the appropriate records.

3.Save the file and exit the text editor.

4.Load the configuration using one of the following commands:

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

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

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

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

Use the -fconfigfile option to specify a file other than the default /etc/prmconf. The -soption displays warnings regarding the configuration file. (The -coption displays a subset of the -swarnings.)

5.Enable PRM’s application manager if it is not already enabled:

#prmconfig -e APPL

Alternatively, enable all PRM resource managers using prmconfig -ewithout any additional arguments:

#prmconfig -e

Launching an application under PRM

There are two ways to start an application under PRM:

•Start the application as you normally would.

The application manager automatically moves it to the PRM group assigned in the PRM configuration file. A user must have the correct permissions to run the application.

•Use the prmrun command. For example, to start the critical_app application in its assigned group CriticalApp:

# prmrun critical_app

The PRM configuration file must contain one record that has no alternate process names for this application. If there is no such record, prmrun fails with an error.

The prmrun command allows any user to run an application in its assigned group as defined in the PRM configuration file, assuming the user has execute permission on the application. This means that any user can execute this command, even if they do not have permission to use the application’s assigned PRM group.

The prmrun -gcommand can be used to override the PRM configuration file and run the application in a specific PRM group if the user has access to the PRM group.

If the application manager is not running, and you do not use prmrun to start the application, it runs in the current PRM group of the user who invokes it.

When the application manager is enabled, any applications not running in their assigned PRM groups are moved to their assigned groups. The exception is an application moved to a specific PRM group with prmmove -gor one started in a specific group with prmrun -g. If an application does not have an assigned PRM group, it runs in the group of the invoking user.
