Oracle Database Resource Manager (the Resource Manager) enables you to optimize resource allocation among the many concurrent database sessions
Elements of the Resource Manager
The elements of the Resource Manager are described in the following table.
Element
Description
Resource consumer group
A group of sessions that are grouped together based on resource requirements. The Resource Manager allocates resources to resource consumer groups, not to individual sessions.
Resource plan
A container for directives that specify how resources are allocated to resource consumer groups. You specify how the database allocates resources by activating a specific resource plan.
Resource plan directive
Associates a resource consumer group with a particular plan and specifies how resources are to be allocated to that resource consumer group.
You use theDBMS_RESOURCE_MANAGERPL/SQL package to create and maintain these elements.
