SYSTEM AND METHOD FOR MANAGING A CHANGE TO A CLUSTER CONFIGURATION

摘要

An apparatus and method are directed to managing a configuration of a cluster of members. The invention employs an atomic cluster configuration approach that includes applying a change to the configuration uniformly across the members in the cluster. Each member within the cluster is initialized to a transaction mode. If all members are in the transaction mode, a change is provided to each member, which evaluates the received change. If the change is determined to be unacceptable for any of the members, the change is determined to be globally unacceptable, and is rejected for all the members in the cluster.
