Oracle Enterprise Manager’s lightweight, three tier architecture offers flexible deployment options and unparalleled scalability. Built on a internet computing model, Enterprise Manager clients, consoles, and other management applications, communicate with the middle tier Management Servers, primarily over IIOP, using standard CORBA.

The Management Servers in turn communicate with third tier Intelligent Agents running on managed systems. Additional Management Servers can be added offering transparent workload balancing and failover, guaranteeing constant and consistent availability.
