further comprising a central database and a central services instance shared by the application server instances in the cluster,
the central services instance having a locking service and a messaging service that enable communication and synchronization
between each of the application server instances in the cluster;
a data layer having the central database in which to store configuration information that defines the cluster of application
server instances;
a logic layer having one or more tasks, the one or more tasks to implement one or more functions of the configuration tool
