1.1.6 Operation with a cluster system

By using a cluster configuration, you can create a highly reliable system that continues to operate even in the event of a system failure. As a result, the programs in Performance Management can continue operation and monitoring 24 hours a day.

The following figure shows an example of operation when a problem occurs on the monitored host in a cluster system.

Set up two environments with the same configuration, and define the environment for normal operation as an executing node and the other for failure operation as a standby node.

For more details about running the programs in Performance Management on a cluster system, see Part 2, 4. Operating PFM - Agent for Oracle in a Cluster System.
