Enterprise Manager Grid Control is Oracle's single, integrated solution for managing all aspects of the Oracle Grid and the applications running on it. Enterprise Manager also allows you to manage single instances of Oracle Database, Application Server, or Collaboration Suite using standalone consoles.
To compliment Oracle Enterprise Management Grid Control, Enterprise Manager Ops Center is Oracle's single, integrated solution for managing all aspects of the data center. It enables you to discover, provision, update, manage, and monitor the physical and virtual assets in one or more of your data centers from a single console.
