The Spotlight home page is a visual representation of the status of the major components of the database. The detail at this level is designed to help you locate and identify bottlenecks as they develop. Additionally, Spotlight provides tools that allow you to identify and rectify inefficiency in your database's configuration.
If Spotlight detects that some component of the Oracle database constitutes a performance bottleneck, the corresponding component generates a visual or auditory alarm. The exact appearance of the alarm depends on how you have configured alarm severities. When an alarm is current you can press F1 to display help for the alarm. Clicking the component (on the home page ) displays the relevant drilldown.
The display is based on the Oracle database architecture. Oracle Architecture Overview
Tip: Hover the mouse pointer over a panel component for more information.
