Abstract
Method for enabling the dynamic modification of cluster configurations, and apparatus including software to perform the method. To enable this dynamic modification, cluster configuration data is stored as a table in a cluster configuration repository that is accessible from all nodes in the cluster. Accordingly, the present invention enables the modification of the cluster configuration from any node in the cluster dynamically. When a reconfiguration command is given, the configuration table is changed and all the nodes in the cluster are notified of the changed configuration in parallel. Following the notification by the nodes of the changed cluster configuration, the changes to the cluster are implemented dynamically as specified by the command.
