HP-UX 11i Version 2 May 2005 Release Notes

General System Administration
HP Partitioning
Chapter 5
107
• Configuration file for wlmpard no longer supports the partitions or weight keywords
•The wlminfo command has various new features:
—The -q option to suppress messages in the wlminfo output
—The group subcommand has an -S option to show data for the PRM_SYS group
— The new subcommand proc shows data for the most active processes
—The host subcommand now has a “CPU Used” column in its output to display
CPU utilization data
•The mincpu / maxcpu keywords are now optional in all cases
• New behavior when the sum of the gmincpu values exceed the total CPU
Previously, when this sum exceeded the total CPU, the values were scaled down
proportionately so that the sum equals the total CPU. Now, those values are treated
as CPU requests to be met before any other requests are considered. Any weight
values assigned to the workload groups apply.
•The wlmpard daemon is no longer required to be running in a partition on the
managed complex
Previously, if WLM was managing the partitions in a complex, wlmpard had to be
running in one of those partitions. Now, wlmpard simply has to be running on a
supported platform with network connectivity to the managed partitions.
Impact
WLM A.03.00 provides the following:
• More flexibility in resource management
• More secure environments
Compatibility
• If you use either the partitions or weight keywords in your wlmpard configuration
file, you will get errors.
Performance
Performance is improved when WLM is used properly, but can degrade when WLM is not
configured appropriately.
