Abstract

The consistency problem in replicated distributed database systems is complicated by the requirement to ensure mutual consistency across the nodes. Traditionally, it is solved by the semi-distributed approach in which all computations of a transaction are carried out at the site of its origination. In this paper, the impact of resource and data contention on the performance of Semi-distributed Algorithm (SDA) has been studied and is compared with Fully-distributed Algorithm (FDA) under different degree of communication overheads with the objective of obtaining some practical guidelines for the design of such systems. Centralized Static Two Phase Locking (CS2PL) is the concurrency control protocol adopted in both models to ensure the serializability of transactions. Results indicate that for both algorithms, data contention rather than resource contention is the dominant factor in affecting the system performance especially when granularity of database is fine. The study also suggests that SDA is more suitable for systems with low communication overheads whereas FDA performs better for systems with high resource contention in communication links and small transaction sizes. FDA has the additional advantage of greater tolerance towards unreliable networks.
