The RESOURCE_MANAGER_CPU_ALLOCATION parameter is deprecated. It is retained for backward compatibility only. Use the CPU_COUNT parameter instead.

The Resource Manager schedules database sessions on the CPUs according to a resource plan that has been configured and enabled by the DBA. Normally, the Resource Manager schedules enough database sessions to keep all CPUs utilized. However, in some scenarios, a DBA may only want to schedule enough database sessions to keep a subset of the CPUs utilized.
