Conﬁguring PRM

Chapter 7100

Specify PRM groups and CPU allocations in group/CPU records. The

conﬁguration ﬁle must contain a group/CPU record for each PRM group

you want to create on your system. The ﬁle must also contain a

group/CPU record for any PRM group listed in a user or application

record. Optionally, deﬁne memory records to assign memory allocations

for the groups. Also optionally, use disk records to assign disk bandwidth

shares for the groups (FSS PRM groups only). Use compartment records,

also optional, to map secure compartments to PRM groups. (Create

secure compartment conﬁgurations using the HP-UX feature Security

Containment—or a PRM utility such as srpgen or prm2scomp.) Use the

optional Unix group records to map Unix groups on the system to PRM

groups.

Each PRM group is denoted by an identiﬁer called a PRM group ID, or

PRMID. The PRMID for an FSS PRM group must be an integer between

0 and 63 (inclusive) or between 0 and 255 (inclusive) starting with

HP-UX v2 Update 2. PRMID 0 is reserved for the PRM_SYS group, and

PRMID 1 is reserved for the OTHERS group. PSET PRM group IDs are

assigned by PRM. When using the PRM interface in HP System

Management Homepage or in HP Systems Insight Manager to create

groups, all PRMIDs are automatically assigned.

You do not need to specify PRM user records for all users on your system.

Users without PRM user records are automatically assigned to the user

default group, OTHERS (PRMID 1).

Create application records for those applications requiring a certain level

of resources. However, you do not need to assign every application to a

PRM group. An application without a PRM application record runs in the

initial PRM group of the invoking user.

For detailed syntax information on conﬁguration ﬁles, see the prmconf(4)

manpage.
