In distributed system, deadlock is a common phenomenon. If a transaction requires more than one resource for its task to be accomplished, such request is called an AND model request. In this paper we have proposed a method for elimination of AND model deadlocks in distributed system. A Multi Granular Locking (MGL) technique is proposed which locks the database at various granules. This technique is used to find the status of the resource which a particular transaction is requesting and protects the database from conflicting access with some preconditions posed for the new transaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
