Overview of Oracle Enterprise Manager and Oracle 11g Features

Describe the capabilities of the Oracle Enterprise Manager.
Oracle Enterprise Manager is a system-management tool that provides an integrated solution for managing your heterogeneous database environment. It combines a graphical console, agents, common services, and tools to provide an integrated, comprehensive systems-management platform for managing Oracle products. From the Oracle Enterprise Manager console, you can:
  1. Administer, diagnose, and tune multiple databases
  2. Distribute software to multiple servers and clients
  3. Schedule jobs on multiple nodes at varying time intervals
  4. Monitor objects and events throughout the network
  5. Customize your display using multiple graphic maps and groups of network objects such as nodes and databases
  6. Administer Oracle Parallel Servers (For information about administering Oracle Parallel Servers, see the Oracle documentation: Oracle Parallel Server Support for the Oracle Enterprise Manager Console Guide.)
The next lesson takes a closer look at the four quadrants of the OEM console.
