Abstract:
1. In a computer system including at least two server nodes, each of which can execute clustered server software, a method for monitoring failure situations to reduce downtime, said method comprising the steps of: (a) detecting an event causing one of said failure situations; (b) determining if said event affects one of said server nodes, and if so; (c) determining if said event exceeds a threshold value, and if so; (d) executing a proactive failover; (e) determining if said event does not affect one of said server nodes, and if so; (f) determining if said event affects the condition of the cluster service, and if so; (g) identifying and initiating an appropriate action to fix said condition or provide a workaround that will preempt an impending failure of the cluster system, or restart a failed cluster system.
