Chapter 9304

par_manual_allocation.wlm

This file, in combination with the global arbiter configuration file in the

next section, can migrate cores across HP-UX Virtual Partitions (vPars)

and/or nPartitions (nPars) based on the number of cores you request on

the command line using wlmsend. The way WLM manages cores depends

on the software enabled on the complex (such as Instant Capacity, Pay

per use, and Virtual Partitions).

Activate the WLM configuration file in each partition. However, you need

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

# Name:

# par_manual_allocation.wlm

# Version information:

# $Revision: 1.4 $

# 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.wlmpar, demonstrates

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

# nPartitions based on manual feedback from the user through the

# wlmsend command.

# The configuration is strictly host-based, not supporting FSS

# or PSET groups; thus, applications within a partition are

# treated as a single workload. Because the utilitypri feature is

# not used in par_manual_allocation.wlmpar, the total number of

# active cores remains constant, but the 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.)
