Site-Locking Protocol for Global Concurrency Control in Multidatabase Systems
Many researches in managing global transactions in multidatabase systems(MDBS) have been proposed to solve problems of ensuring the global serializability. In these method, a few opportunities are provided to the global transaction to execute concurrently. We concentrate our attention on 1) maintaining consistent database state that is defined by global integrity constraints and 2) investigatio...
متن کاملOn concurrency control in multidatabase systems
A multidatabase system is a system that supports data access to a collection of preexisting autonomous database systems. Concurrency control in such an environment is much more diicult in nature than that in centralized or distributed (homogeneous) database systems. Many factors, especially the autonomies, bring diiculties to it. In this paper, we classify the multidatabase environment into val...
متن کاملA Survey of Concurrency Control Algorithms in the Operating Systems
Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling...

متن کاملPerformance Analysis of Global Concurrency Control Algorithms and Deadlock Resolution Strategies in Multidatabase Systems∗
Even though many global concurrency control (GCC) algorithms have been proposed to ensure global serializability, their performances are not well understood. In this paper, we address the GCC problem from the performance perspective, and evaluate the performance of several GCC algorithms using a multidatabase simulation model. We also evaluate the performance of alternative deadlock resolution ...
