5. Enable PRM’s application manager if it is not already enabled:
#prmconfig -e APPL
Alternatively, enable all PRM resource managers using prmconfig -e without any additional
arguments:
#prmconfig -e
Assigning Unix groups to PRM groups
Unix groups are collections of users given Unix permissions as a whole. PRM allows you to map
Unix groups to PRM groups without having to specify each user in the Unix group. With a Unix
group record, any process running as a specific Unix group can be assigned to a PRM group.
You can add, modify, and remove assignments of Unix group to PRM groups as discussed in the
following sections:
• “Adding/modifying a Unix group’s PRM group assignment ” (page 77)
• “Removing a Unix group’s PRM group assignment ” (page 78)
Unix group record syntax
This section explains the syntax of Unix group records.
Unix group records assign Unix group to PRM groups.
Use the following syntax when specifying a Unix group record:
#!UXGRP:UNIX_GROUP_NAME:{GROUP | (NONE)}
where
#!UXGRP Indicates the start of a Unix group record. (The # character does not
denote the start of a comment in this case.)
UNIX_GROUP_NAME Is the alphanumeric name (of no more than 255 characters) of an existing
Unix group.
A Unix group can have no more than one record.
This record type yields precedence to application records, compartment
records, and user records.
GROUP The PRM group to which the Unix group is to be mapped. If you are using
group hierarchies, the group you specify must not have any child groups.
(NONE) You can specify (NONE) in place of a group name if you would like to
explicitly show in your configuration file that a Unix group is not to be
mapped to a PRM group.
Consider the following example Unix group records:
#PRM Unix group records
#!UXGRP:finance_dept:finance
#!UXGRP:users:(NONE)
#!UXGRP:mail:tools/mail
These Unix group records map:
• The Unix group finance_dept into the group finance
• The Unix group users into the placeholder (NONE)
• The Unix group mail into the group tools/mail
Adding/modifying a Unix group’s PRM group assignment
To add or modify a Unix group record, follow these steps:
