A 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 کاملA Unified Approach to Concurrency Control and Transaction Recovery (Extended Abstract)
Conventional transaction management in shared databases is traditionally viewed as a combination of two orthogonal problems. One is to guarantee correctness when several transactions are executed concurrently. This is ensured by the concurrency control component of a transaction processing system. The other is to ensure the correctness of the database in spite of transaction aborts and system f...
متن کاملAtomicity Policies using Design Patterns
This paper describes three object-oriented design patterns local serialization, global serialization and recovery and their integration to support atomic objects. The paper emphasizes the policies each pattern offers and the heterogeneity of policies resulting from their integration. The policies supported by the patterns include: pessimistic and optimistic serialization; static, dynamic and hy...
متن کاملConcurrency Control and Recovery Management for Open e-Business Transactions
Concurrency control mechanisms such as turn-taking, locking, serialization, transactional locking mechanism, and operational transformation try to provide data consistency when concurrent activities are permitted in a reactive system. Locks are typically used in transactional models for assurance of data consistency and integrity in a concurrent environment. In addition, recovery management is ...
متن کاملUnifying concurrency control and recovery of transactions
Transaction management in shared databases is generally viewed as a combination of two problems, concurrency control and recovery, which have been considered as orthogonal problems. Consequently, the correctness criteria derived for these problems are incomparable. Recently a uniied theory of concurrency control and recovery has been introduced that is based on com-mutativity and performs trans...
