Getting started with HP-UX Workload Manager

• par_manual_allocation.wlm, par_manual_allocation.wlmpar—These configuration files demonstrate

how WLM can resize HP-UX Virtual Partitions (vPars) and nPartitions (nPars). In this configuration,

you manually request the number of cores for a partition by using the wlmsend command to feed

the request to WLM. Configure WLM in each partition on the system using the .wlm file. Configure

the WLM global arbiter in one partition using the .wlmpar file.

• par_usage_goal.wlm, par_usage_goal.wlmpar— These configuration files demonstrate how WLM

can resize HP-UX Virtual Partitions and nPartitions, shifting cores between the partitions on a system.

Configure WLM in each partition on the system using the .wlm file. Configure the WLM global

arbiter in one vPar using the .wlmpar file.

In addition, WLM has several free toolkits that simplify integrating WLM with various major

applications. Each toolkit comes with example WLM configurations as well. Some of these toolkits

help you use WLM with:

• Apache Web server

• Oracle databases

• BEA WebLogic Server

• SAP software

• HP-UX SNMP Agent

For information on these toolkits and their configuration files, see the wlmtk(5) manpage or:

Alternative methods for placing processes in workload

groups

When a system is divided into workload groups, each application must go into a workload group. By

default, processes run by root users go into the PRM_SYS group, and processes run by non-root users

go into the OTHERS group. However, the WLM configuration file enables you to change the workload

group in which a particular user’s processes run by adding user records to the WLM configuration

file. Furthermore, you can specify the workload groups in which processes run by adding application

records to your WLM configuration, or defining secure compartments that isolate the processes in

specified workload groups. You can even define process maps that include your own criteria for

placing processes in workload groups. For more information on these methods for placing processes

in workload groups, see the white paper, “HP-UX Workload Manager: a quick reference,” available

from the information library at:

Outside the configuration file, you can use the prmrun and prmmove utilities discussed in the

following sections to manage process placement.
