How do I use WLM?
Steps for using WLM
Chapter 4 129
NOTE Running the wizard requires Java Runtime Environment version 1.4.2
or later and, for PRM-based configurations, PRM C.03.00 or later. (To
take advantage of the latest updates to WLM, use the latest version of
PRM available.)
The WLM GUI, at /opt/wlm/bin/wlmgui, also allows you to configure
WLM without directly editing a configuration file; however, you do need
to be familiar with the configuration file syntax.
In addition, WLM provides a number of example configurations in
/opt/wlm/examples/wlmconf/ that you can modify to fit your environment.
Also, the WLM Toolkits provide numerous example configurations. For
pointers to those configurations, see wlmtk(5).
To use WLM:
Step 1. Identify the workloads to run on a given system.
Each workload can consist of one or more applications and multiple
users.
Step 2. Separate the workloads into three types:
• Workloads without goals (shares-based)
•Workloads with CPU usage goals (goal-based)
• Workloads with performance goals (goal-based)
For information on the types of workloads and their associated SLOs, see
“Shares-based SLOs vs goal-based SLOs” on page 118.
Start a WLM configuration file using a text editor. Define your
workloads.
Step 3. For workloads without goals, add shares-based SLOs to your
configuration.
Determine the amount of CPU resources each workload requires so that
you can set appropriate CPU shares requests. One method for
determining CPU needs is illustrated in the example configuration file
“manual_entitlement.wlm” on page 298.
