HP-UX Workload Manager A.02.03.01 Release Notes for HP-UX 11i V1.0 and HP-UX 11i V2.0

HP-UX Workload Manager Release Notes

Announcement

HP-UX Workload Manager (WLM) A.02.03.01 supports HP-UX 11i V1.0 (B.11.11) on HP9000

servers; also, it supports HP-UX 11i V2.0 (B.11.23) on either HP9000 servers or HP Integrity

servers.

HP-UX 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 Process Resource Manager (PRM), HP-UX Virtual Partitions, node partitions,

and processor sets.

HP-UX WLM offers the following features:

• Automatic allocation of CPU resources to your most critical applications

(allocation of time slices on CPUs as well as whole CPUs when managing processor sets,

virtual partitions, or node partitions)

• User-configured allocation of real memory and disk bandwidth resources

• Shares-based and goal-based SLOs

• CPU shares-per-metric allocations, which allow you to give a workload, for example, 2% of

the CPU for each process in the workload

• Multiple SLOs at different priorities, allowing you to have a “must meet” goal and

optional stretch goals for each workload

• Passive mode for analyzing a configuration’s behavior

• Audit and billing data

• Ability to set minimum and maximum amounts of CPU available to a workload

• Time-based and metric-based activation of SLOs, including the ability to activate SLOs

associated with a Serviceguard package on failover

• EMS resources for monitoring and alarming on Workload Manager events, including

notification of when iCOD (Instant Capacity on Demand) reserves could help reduce SLO

failures

• GUI for creating, modifying, and deploying WLM configurations locally and on remote

systems

• Servicecontrol Manager integration, allowing you to remotely control WLM running on

numerous nodes from a single point of administration
