A.
setting idle timeout limits on resource plans

B.
saving storage space by using compressed backup sets

C.
creating jobs that will run automatically at a scheduled time

Explanation:
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 you to 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 generating more
I/O than you specify. RMAN provides the functionality of saving storage space by using
compressed backup sets. The Scheduler provides the functionality of creating jobs 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.
