The Resource Manager solves many resource allocation problems that an operating system does not manage well, including: Excessive overhead Inefficient scheduling Inappropriate allocation of resources Inability to manage database-specific resources The Resource Manager helps overcome these problems by giving the database more control over allocation of hardware resources and enabling you to prioritize work within the database.
