HP-UX Workload Manager
HP-UX Workload Manager (WLM) provides goal-based workload management. This
management enables automatic resource allocation and application performance
management through the use of prioritized service-level objectives (SLOs). It provides
this functionality by automating features of HP-UX Virtual Partitions, Node Partitions,
Processor Sets, and HP Process Resource Manager (PRM).
NOTE Process Resource Manager and HP-UX Workload Manager both make use of the PRM
API. Consequently, only one of these products should be used at a time. (See also “HP
Process Resource Manager (PRM)” on page 140.)
