uses login names to assign users to specific PRM groups, PRM is not able to distinguish between users attaching to the system using socket connections.

Online cell operations

If you want to perform online cell operations, and:

•Your PRM configuration contains memory records

Stop memory management (prmconfig -d MEM), then after the online cell operation has completed, restart memory management (prmconfig -e MEM).

•Your PRM configuration uses PSETs

Reset PRM (prmconfig -r), then after the online cell operation has completed, restart PRM management (prmconfig -ie[-ffile]).

For more information on online cell operations, see parolrad(1M).

Backing up PRM files

If you would like to make a backup of your PRM environment, be sure to back up the following files:

•/etc/prmconf

The default PRM configuration file

•/etc/opt/prm/conf/*

The suggested location for additional PRM configurations. Files in this directory should have the owner set to hpsmh.

•/opt/prm/conf/*

A location previously suggested for additional PRM configurations

•/etc/rc.config.d/prm

Configuration file used by /sbin/init.d/prm

•/etc/shells and /opt/prm/shells

Files used by PRM to ensure PRM’s application manager can differentiate shell scripts from one another; these files can also help the application manager differentiate Java binaries

•/etc/cmpt/*.rules

File containing compartment rules configured for the system (This file is actually an HP-UX 11i Security Containment file. If you have created Secure Resource Partitions, you will have a *.rules file on your system, although not necessarily in /etc/cmpt/. The Security Containment feature is available starting with HP-UX 11i v2.)
