Lock Based Concurrency Control and Deadlock Detection In Distributed Database System

Abstract

This study examines Lock based Concurrency algorithms for distributed database system. This study includes basic Lock Manager, Strict Two-Phase Locking and Centralized Two-Phase Locking algorithms and implementation of CLPL in distributed database system where Lock Manager is centralized and Transaction Manager is distributed. Numbers of experiments are performed to evaluate the locking algorithm on the behaviors of transaction. This study also includes a distributed deadlock detection algorithm and its implementation.
