ABSTRACT A formal model for atomic commit protocols for a distrib­uted database system is introduced. The model is used to prove exis­tence results about resilient protocols for site failures that do not parti­tion the network and then for partitioned networks. For site failures, a pessimistic recovery technique, called independent recovery, is intro­duced and the class of failures for which resilient protocols exist is identified. For partitioned networks, two cases are ...
