Individual consoles can manage single databases or multiple
databases. Where EM is managing Oracle deployed on a cluster of computers, it is
sometimes referenced as Grid Control.
The home page for Grid Control lists the software being managed and provides a
high-level view of the status of Grid components. You can drill from Grid Control
into the consoles for individual databases, application servers, and other targets.
Figure 5-1 illustrates a typical Grid Control home page.
The Enterprise Manager architecture includes the following components:
Oracle Management Agents
These agents monitor targets for health, status, and performance. Agents automatically
discover all Oracle components and also report back other relevant
hardware and software configuration information to EM via HTTP/HTTPS.
Each monitored Oracle instance has its own agent.
