Configuring and enabling PRM on the command line
Configuring PRM
Chapter 7 101
In addition to syntax requirements, it is important to keep the following
configuration file requirements in mind:
• PRM automatically assigns system processes to the group
PRM_SYS (PRMID 0) and calculates this group’s resource needs. You
do not need to specify the PRM_SYS group in the PRM configuration
file.
NOTE If you are configuring PRM to manage memory resources, the PRM
configuration file must not contain a PRM_SYS group. If the group is
already present, delete it.
• The user default group, OTHERS (PRMID 1), is required in the PRM
configuration file.
• Nonroot users cannot have access to the system group PRM_SYS
(PRMID 0).
The default PRM configuration file, /etc/prmconf, is created
automatically when you install PRM. Execute the prmloadconf utility to
create the /etc/prmconf file if it is not present. To create the same
configuration file with a name other than /etc/prmconf, use
prmloadconf -f configfile, specifying your preferred name in place of
configfile. Keep alternate configuration files in the directory
/etc/opt/prm/conf/, with the owner set to hpsmh.
Use the configuration file created by prmloadconf as a template to
establish your specific configuration. Customize this file based on your
configuration planning. Configuration planning is discussed in “PRM
configuration planning” on page 71.
