Resource consumer groups let you group user sessions together by resource requirements. Resource consumer groups are different from user roles; one database user can have different sessions assigned to different resource consumer groups. You can then use a resource plan to specify how the resources are to be distributed among various resource consumer groups.
You can use the Database Resource manager in Oracle Enterprise Manager to automatically assign sessions to specific consumer groups by setting up mappings between session attributes and consumer groups. You can also map consumer groups in specified categories to users, client programs, modules, or services.
