SYSTEM AND METHOD FOR IMPLEMENTING A CLUSTER TOKEN REGISTRY FOR BUSINESS CONTINUITY

摘要

Method and system for implementing a cluster token registry (“CTR”) process in a cluster comprising a plurality of interconnected nodes each having a CTR associated therewith are described. In one embodiment, the method comprises, responsive to a client signing in at one of the nodes, the client registering a cluster-wide token with the CTR of the node, thereby casting a vote in connection with the token; determining whether prerequisites for granting the token have been met; and, responsive to a determination that the prerequisites have been met, granting the token. The method further comprises periodically determining whether the vote in connection with the token vote has been refreshed by the client and, responsive to a determination that the vote in connection with the token has not been refreshed by the client, de-registering the client.
