Sun Cluster System Administration Guide for Solaris OS

Fair Share Scheduler

The first step in the procedures to assign CPU shares to resource groups is to set the scheduler for the system to be the fair share scheduler (FSS). By default, the scheduling class for Solaris OS is timesharing schedule (TS). Set the scheduler to be FSS to have the shares configuration take effect.

You can create a dedicated processor set regardless of the scheduler class you choose.
