HP-UX Workload Manager
HP-UX Workload Manager (WLM) provides goal-based workload management, enabling
automatic resource allocation and application performance management. HP-UX WLM
uses a configuration file specifying workloads and their prioritized service-level
objectives (SLOs). HP-UX WLM automatically allocates CPU resources to the workloads
based on priorities and current performance.
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
“Process Resource Manager (PRM)” on page 105.)

new at 11i
original release
Besides resource shares, the bundling of version A.01.00.02 with PRM provides:
• An SNMP agent for accessing PRM data
• Display of resource percentages to two decimal places (was formerly integer
precision)
• Expanded field length for PRM group names in PRM’s monitoring utilities
(30-character field was formerly 14-character field)
• In-kernel memory management
This version of HP-UX WLM does not take advantage of PRM’s hierarchical groups.
