6 Monitoring Performance Alerts

Oracle Database includes a built-in alerts infrastructure to notify you of impending problems with the database. Alerts are a type of event and events comprise incidents. A problem is a special type of incident.

By default, Oracle Database enables some alerts, including the following:

• Archive Area Used

• Current Open Cursors Count

• Recovery Area Free Space

• Tablespace Space Used

In addition to these default alerts, you can set metric thresholds so that Oracle Database generates alerts to notify you about the database performance conditions that you specify.

This chapter contains the following sections:

• Setting Metric Thresholds for Performance Alerts

• Responding to Alerts

• Clearing Alerts
