HP-UX Workload Manager A.03.01 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

Patches and fixes in this version

WLM version A.03.01 includes the following fixes.

WLM miscalculates CPU usage in strictly host-based configurations

In previous releases, WLM included a processor’s CP_WAIT time in the usage calculation for a

strictly host-based configuration (a configuration that does not include a prm structure). This

caused WLM to report higher-than-normal usage rates for some workloads when the actual

CPU usage was much lower. In any strictly host-based configuration with the utilitypri

keyword specified in the wlmpard configuration file, more CPUs would get activated.

WLM no longer includes CPU CP_WAIT time when calculating usage for a strictly host-based

configuration.

This fix addresses CR# JAGaf81986.

Global arbiter can drop CPUs

In previous releases, a small timing hole in WLM existed, causing the global arbiter (wlmpard)

to drop CPUs due to problems with Instant Capacity, virtual partitions, or a dropped

connection from a client.

This timing hole has been removed, thereby preventing CPUs from being dropped

inadvertently.

This fix addresses CR# JAGaf78744.

WLM GUI does not remove the last config element

In previous releases, if multiple configuration elements existed in workload groups, service

levels, metrics, and so forth, the WLM GUI did not remove all the elements when the

assortment was removed. As a result, the elements continued to appear in the WLM

configuration.

The WLM GUI has been fixed to remove all the elements from the configuration when the

assortment is removed.

This fix addresses CR# JAGaf78971.
