Distributed database system provides resource sharing environment for optimal performance of various database activities, especially when data is spread over a large number of sites. Distributed nature of transactions occurring at different sites and requiring resources from diverse sites pose various operational problems, such as deadlocks, concurrency and data recovery. A deadlock may occur when a transaction enters into wait state which request resource from other blocked transactions. The deadlocks are handled in three phases namely deadlock detection, deadlock avoidance and deadlock detection.
