20 Maintaining Enterprise Manager

Enterprise Manager provides extensive monitoring and management capabilities for various Oracle and non-Oracle products. Used to manage your heterogeneous IT infrastructure, Enterprise Manager plays an integral role in monitoring and maintaining the health of your IT resources. It is therefore essential to ensure Enterprise Manager itself is operating at peak efficiency.

To help you maintain your Enterprise Manager installation, a variety of enhanced self-monitoring and diagnostic functionality is available from the Enterprise Manager console. These functions are designed to help you understand and monitor various components of Enterprise Manger, monitor/measure the quality of services Enterprise Manager provides, diagnose failures quickly, and manage Agents more easily.
