Primary Copy Synchronization for DB-Sharing.

Information Systems 11 (4), 275-286, 1986




In a database sharing (DB-Sharing) system multiple loosely or closely coupled processors share access to a single set of databases. Such systems promise better availability and linear growth of transaction throughput at equivalent response time compared to single processor database systems. The efficiency of a DB-Sharing system heavily depends on the synchronization technique used for maintaining consistency of the shared data. A promising algorithm is the primary copy approach which will be presented in this paper.
