In the basic monitoring mode, the database agent for Oracle detects a failure if the database or a listener service is not running. In the detail monitoring mode, the agent detects failure if a preconfigured SQL script cannot execute or access the database or if the listener service is not running.

The detail monitoring interval can be defined using the IndepthMonitorCount attribute.

When the agent detects a failure, the Oracle service group switches to the next available system listed in the service group's SystemList attribute. VCS starts the configured Oracle and listener services on the new system, thus ensuring high availability for the Oracle services and data.
