Simply assigning a workload unit to a resource unit is insufficient for managing the quantity of resources that users consume. To manage resources, the Oracle Solaris operating system provides a set of flags, actions, and signals that are referred to collectively as resource controls. Resource controls are stored in the /etc/project file or in a zone's configuration through the zonecfg command described in zonecfg (1M) . The Fair Share Scheduler (FSS), for example, can allocate shares of CPU resources among workloads based on the specified importance factor for the workloads. With these resource controls, a system administrator can set privilege levels and limit definitions for a specific zone, project, task, or process. To learn how a system administrator uses resource controls, see Chapter 6, About Resource Controls, in Administering Resource Management in Oracle Solaris 11.2 . For programming considerations, see Chapter 5, Resource Controls.
