Explanation/Reference:
* Enterprise Manager Groups enable administrators to logically organize distributed targets for efficient and
effective management and monitoring
* By combining targets in a group, Enterprise Manager provides management features that enable you to
efficiently manage these targets as one group. Using the Group functionality, you can:
/View a summary status of the targets within the group.
/Monitor incidents for the group collectively, rather than individually.
/Monitor the overall performance of the group.
/Perform administrative tasks, such as scheduling jobs for the entire group, or blacking out the group for
maintenance periods.
