Abstract

The Eternal system provides CORBA applications with robust fault tolerance and the ability to be upgraded without a service interruption. The Eternal Evolution Manager handles both interface-preserving upgrades and interface-changing upgrades. The syntax and semantics of the application objects´ IDL interfaces are unchanged by an interface-preserving upgrade. Interface-changing upgrades allow modification to one or more application object´s IDL interfaces. Because modification to an object´s IDL interface can affect clients of that object, an interface-changing upgrade requires coordinating the upgrade of multiple application objects at the same time
