You can use the failover monitoring option provided by the ORACLE application and the advanced failover monitoring option provided by the ORACLE_FAILOVER application to monitor Oracle instances in a failover or cluster environment. For a description of how PATROL for Oracle monitors failover and clustering environments, see Failover and cluster monitoring scenarios.
To use failover monitoring, you must establish the PATROL link between the primary instance and the failover instance. This is done by using the Failover Monitoring > Configure command from the ORACLE_INSTANCE menu. Because the PATROL Agent is not running in the cluster-specific mode, the PATROL history for each instance is interrupted.
Configuring failover monitoring describes how to set up PATROL to monitor the failover instance.
