Abstract :
A method for integrated concurrency control and recovery, applicable to heterogeneous multidatabase systems, is proposed. The responsibility for two-phase local commitment and recovery of the prepared state at participants is taken over by an entity called 2PC Agent. The main importance of the method is in preserving global serializability in the presence of a certain class of participant-related failures. The related recovery methods, including a novel failure-time optimistic concurrency control method, are presented
