Managing a clustered computer system

摘要

A clustered computer system provides both speed and reliability advantages. However, when communications between the clustered computers are compromised those same computers can become confused and corrupt database files. The present method and apparatus are used to improve the management of clustered computer systems. Specifically, the system expands the number of nodes available for failover conditions. Further, provision is made for returning the system to an initial state after a failover event.
