Abstract

Distributed systems use optimistic message logging for recovery from transient process failures. Such a recovery is facilitated by asynchronous message logging and check-pointing. It is also supported by garbage collection which requires identifying messages in stable storage that are no longer needed for the process of recovery. For this purpose, it is necessary to keep track of message dependencies between process states. A model to keep track of state dependencies using dependency graphs has been proposed.
