HP-UX Workload Manager
HP-UX Workload Manager (WLM) version A.02.02 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).
Summary of Change
HP-UX WLM version A.02.02 includes the following:
• New GUI that allows local and remote management of WLM systems
• Automatic resizing of node partitions (nPars) that use iCOD software
• Configuration Wizard supports more WLM configuration options
• PSET-based workload groups with no active SLOs have their CPU count reduced to
zero
• cpushares keyword supports an offset
• To support nPars in addition to vPars:
— wlminfo's vpar command has changed to par
— wlmpard's -l vpar is now -l par
•New cntl_smooth keyword allows you to get a running average of a metric from a
data collector, smoothing out dips and spikes in the metric before it is used by WLM
• perl is expected to be in /opt/perl/bin/
