per use, and Virtual Partitions). This file also shows how several

additional par structure keywords (including utilitypri) are used

(these are commented out).

Activate the WLM global arbiter’s configuration in only one partition.

However, activate the WLM configuration file in each partition to be

managed by WLM.

# Name:

# par_usage_goal.wlmpar

# Version information:

# $Revision: 1.7 $

# Caveats:

# DO NOT MODIFY this file in its /opt/wlm/examples/wlmconf location!

# Make modifications to a copy and place that copy outside the

# /opt/wlm/ directory, as items below /opt/wlm will be replaced

# or modified by future HP-UX WLM product updates.

# Purpose:

# This example, used with par_usage_goal.wlm, demonstrates WLM’s

# ability to resize either HP-UX Virtual Partitions or nPartitions

# based on workload usage.

# This configuration is for the WLM global arbiter, wlmpard, which

# takes CPU requests from the WLM instances in each partition.

# It then shifts cores between the partitions based on the requests

# and priorities of partition workloads. Because the utilitypri

# feature is not used here, the total number of active cores remains

# constant, but the CPU allocations for partitions change

# automatically to meet each partition’s usage needs. The way WLM

# manages CPU resources depends on the software enabled on the

# complex (such as Instant Capacity, Pay per use, and Virtual

# Partitions).

# Dependencies:

# This example was designed to run with HP-UX WLM version A.03.00 or

# later.

# To implement WLM’s dynamic partition resizing:

# See the instructions in par_usage_goal.wlm for the steps needed to
