HP Process Resource Manager (HP PRM) is a resource management tool used to control the amount of resources that processes use during peak system load.

HP PRM can manage allocation of the following resources:

• CPU
  Ensures a minimum allocation of CPU; can also simultaneously cap CPU resource usage for each group in the configuration. (Starting with HP-UX 11i v3, per-group capping is available.)

• Memory
  Ensures a minimum allocation of private real memory; can also cap private memory usage. Allows you to allocate an exact amount of shared memory.

• Disk bandwidth
  Ensures a minimum allocation of disk bandwidth.

For information on PRM's role in Virtual Server Environments, visit the VSE web site.

Secure Resource Partitions
HP-UX Secure Resource Partitions (SRP) are used to consolidate multiple applications within a single image of the HP-UX 11i operating system. Applications running in an SRP operate as though they were running in an individual system. SRPs can be started and stopped in the same manner as a single system. User log-in can be directed to a specified SRP, and each SRP can be assigned a private IP address. CPU, memory and disk resources can be managed and scheduled on a per-SRP basis.

SRP uses a combination of Security Containment compartments and HP Process Resource Manager to provide controlled isolated of execution environments and system resources.

HP-UX 11i Processor Sets
PRM supports HP-UX 11i Processor Sets. For background information on processor sets, see the Processor Sets Product Note and the technical white paper HP-UX Processor Sets.

• For HP-UX 11i v1 (B.11.11), you can download processor sets from the software depot page for the HP-UX Software Pack (Optional HP-UX 11i Core Enhancements). You must also install the HP-UX 11i Quality Pack.

• For HP-UX 11i v2 (B.11.23) and later, the processor sets feature is included in the operating system.
