Fault resistant 24.times.7 topology for business process management ecosystem

Abstract:

A system and computer-implemented method for providing a load-balanced server architecture to end users and allowing software on the server architecture to be updated without downtime during a transition to the new software version. Run-time errors due to incompatibilities between datatypes, interfaces, deserialization methods, and classes loaded by class loaders in object oriented server software may be avoided by using the system to track a software version used in association with a particular task. By routing requests related to a particular task to a particular server running the same software version, compatibility is maintained and efforts to migrate data across software servers or add code to handle cross-version compatibility are unnecessary.
