Enabling resource managers with prmconfig

To start all PRM resource managers (CPU, memory, disk bandwidth, and

application), enter the following command:

# prmconfig -e

If there are no memory records, the memory manager is not started.

However, even if there are no application records, the application

manager does start. Also, the disk bandwidth manager starts—even

when there are no disk records—if you specify prmconfig -e DISK; this

allows you to perform monitoring.

The prmconfig -e command controls only whether the PRM resource

management is being used and does not change the conﬁguration.

However, PRM must be conﬁgured (have a conﬁguration loaded) for this

option to be valid.

When PRM is enabled, it takes precedence over standard HP-UX

resource management when the system is at peak load.

If you wish to enable PRM for one type of resource only, specify the

appropriate keyword as shown in Table 7-2.

NOTE You must enable the application manager to enforce application records,

user records, compartment records, and Unix group records.
