Abstract
A distributed locking system and method for a clustered system having a distributed system for storing cluster configuration information is provided. One aspect of the present invention allows a process or thread in a high availability solution to obtain a distributed lock on all relevant nodes in a clustered system. Another aspect of the present invention allows more than one thread to obtain a lock and perform a critical operation on different nodes concurrently.
