Note:

The RESOURCE_MANAGER_CPU_ALLOCATION parameter is deprecated. It is retained for backward compatibility only.

RESOURCE_MANAGER_CPU_ALLOCATION specifies the number of CPUs that the Resource Manager should utilize. The Resource Manager controls how a system's CPUs are utilized by its database's sessions.

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.
