Abstract
A method and system for transparently failing over a computer name with a legacy application running in a server cluster. When the application is set for failing over in the cluster, the cluster software locates a virtual computer name on which the application is dependent, and associates the virtual name with the application. When the application runs and requests its computer name from the system, the system looks for the virtual computer name, and, if detected, the system returns the virtual computer name to the application as the computer name. The virtual computer name thus moves with the application regardless of the machine on which it is running in the cluster. When the application is not set for failing over in the cluster, the system instead returns the actual machine name.
