Deadlock prevention in a distributed database system

P. Krishna Reddy, Subhash Bhalla

Abstract

The distributed locking based approaches to concurrency control in a distributed database system, are prone to occurrence of deadlocks. An algorithm for deadlock prevention has been considered in this proposal. In this algorithm, a transaction is executed by forming wait for relations with other conflicting transactions. The technique for generation of this kind of precedence graph for transaction execution is analyzed. This approach is a fully distributed approach. The technique is free from deadlocks, avoids resubmission of transactions, and hence reduces processing delays within the distributed environment.
