Process Resource Manager

HP Process Resource Manager (PRM) is a resource management tool that enables the user to

control the allocation of CPU, private and shared real memory, and disk bandwidth resources

to multiple workloads or users within an HP-UX instance. This capability enables the user to

stack multiple applications within a single HP-UX instance and ensure that the critical

applications and users get system resources in a timely manner.

PRM is policy-based; it manages resources based on policies you define. These policies

govern resource consumption by users, applications, and UNIX groups. You can define

multiple policies to manage resources. For example, you might have one policy during the

day and another one at night. You can specify resource policies to PRM through a text

configuration file or an easy-to-use GUI.

Features

Process Resource Manager provides the following features:

• Enables the user to define policies to manage the allocation of the most critical shared

resources: CPU, private and shared real memory (including isolation of a pSet’s memory),

and disk bandwidth

• Supports resource allocation policies for both users and applications, which makes PRM

valuable for interactive and application systems

• Supports resource allocation policies for UNIX groups

• Supports multiple mission-critical applications on a single image of HP-UX by ensuring

application isolation and policy-based resource allocation

• Requires no mod ifications f or applications to operate under PRM control (Any application

can work with PRM.)

• Enables you to modify the PRM configuration dynamically at any time, even while the

system is under load (PRM and all applications continue to run on the system when the

resource policy is mod ified—there is no downtime. This functionality allows the resource

allocation policy to be changed as needed by business goals that vary based on the time
