Introduction
Examples of solutions that WLM provides
Chapter 152
• You run Serviceguard and need to ensure proper prioritization of
workloads after a failover.
• You want more control over resource allocation than PRM provides.
Examples of solutions that WLM provides
The following sections provide examples of how WLM SLOs can provide
a wide variety of business solutions. The SLOs are outlined without
including the necessary configuration file syntax. For information on the
configuration file syntax, see Chapter 5, “Configuring WLM,” on
page 135.
SLOs that ensure a specified amount of CPU shares
for workloads
The solutions in this section illustrate shares-based SLOs. They grant a
workload a specified amount of CPU shares.
Reserving CPU resources all of the time
In this first example, the SLO requests a fixed allocation of CPU shares
for the Marketing workload, reserving a portion of the server’s available
CPU resources. The 300 CPU shares being reserved equate to 3 cores
(when managing SLOs for partitions, WLM equates each core to 100
shares). This SLO is priority 1 and is in effect at all times.

Reserving CPU resources at specified times
This SLO requests a fixed allocation of 800 CPU shares. However, the
associated workload contains a payroll application that only runs twice a
month. Consequently, the SLO is enabled only twice a month, on the
15th and 28th.
