# Name:

# par_manual_allocation.wlmpar

# Version information:

# $Revision: 1.6 $

# 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_manual_allocation.wlm, demonstrates

# WLM’s ability to resize HP-UX Virtual Partitions and/or

# nPartitions based on manual feedback from the user through the

# wlmsend command.

# 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 change to meet the manual requests.

# 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 instructions in par_manual_allocation.wlm for the steps

# needed to configure WLM for dynamic partition resizing.

# The WLM global arbiter’s interval is set to 10 seconds. Every interval,

# the arbiter takes CPU requests from the WLM instances running on the

# partitions and makes changes in the partitions’ CPU allocations. (If you

# change the global arbiter interval, be sure it is greater than the
