Abstract

In CORBA-based applications that depend on object replication for fault tolerance, inconsistencies in the states of the replicas of an object can arise when concurrent threads within those replicas perform updates in different orders. By imposing a single logical thread of control on every replicated multithreaded CORBA client or server object, and by providing deterministic scheduling of threads and operations a cross the replicas of each object, the Eternal system achieves consistent object replication. The Eternal system does this transparently, with no modification to the application, the ORB, or the concurrency model employed by the ORB
