Abstract

Algorithms for scheduling of distributed transactions in a heterogeneous
multidatabase, in the presence of failures, are presented. The algorithms
of prepare certification and commit certification protect against
serialization errors called global view distortions and local view
distortions. View serializable overall histories are guaranteed in the
presence of most typical failures. The assumptions are, among others, that
the participating database systems produce rigorous histories, e.g. by
using the strict two-phase locking policy, and that no local transaction
may update the data accessed by a global transaction that is in the
prepared state. The main advantage of the method, as compared to other
known solutions, is that it is totally decentralized.
