    The Resource Manager provides the functionality of setting idle timeout limits on resource plans and assigning

    priorities to jobs to manage access to system resources. The Resource Manager feature of an Oracle database

    provides a set of APIs that allow you to manage resources automatically. The Resource Manager allows youto

    distribute processing resources to users so that they are used efficiently, create undo pools to be used by

    specific groups of users, create session pools for users, limit the number of active sessions for a specific group

    of users, and prevent processing-intensive jobs from executing longer than expected or from generatingmore

    I/O than you specify.

    RMAN provides the functionality of saving storage space by using compressed backup sets.

    The Scheduler provides the functionality of creatingjobs that will run automatically at a scheduled time. The

    Tablespace Monitoring feature provides the functionality of creating alerts to perform notification when

    tablespaces are low on available space resources. Monitoring and Tuning RMAN
