Abstract
A method for integrated concurrency control and recovery, applicable to heterogeneous multidatabase systems is proposed1. The role of the participant in the two-phase commit protocol is laid on an entity called 2PC Agent associated with the local database system. The main importance of the method is in preserving global serializability in the presence of unilateral aborts and site failures. The method requires the participating database systems to use the strict two-phase locking or a comparable rigorous concurrency control policy.
