Each application and service running on a cluster has specific CPU needs. Table 2–2 lists the CPU control activities available on different versions of the Solaris Operating System.

The Fair Share Scheduler must be the default scheduler on the cluster if you want to apply CPU shares.
Controlling the CPU assigned to a resource group in a dedicated processor set in a non-global zone offers you the strictest level of control of CPU because if you reserve CPU for a resource group, this CPU is not available to other resource groups. For information about configuring CPU control, see Chapter 9, Configuring Control of CPU Usage, in Sun Cluster System Administration Guide for Solaris OS.
