Quorum-Based Optimistic Concurrency Control in Replicated DHTs
2009 International Symposium on Information Engineering and Electronic Commerce, 2009Distributed Hash Tables (DHTs) provide a scalable solution for data sharing in P2P systems. To achieve fault tolerance and ensure high data availability, DHTs typically rely on data replication. However, nodes churn, lacking of global view and existence of malicious nodes in P2P environment bring new challenges to the concurrency control for replicated

An Optimistic Concurrency Control Protocol for Replicated Databases
2009This paper presents an optimistic approach to transaction management for replicated databases. We propose a new transaction management protocol that guarantees global serializability and freedom from distributed deadlocks without relying on any properties of the DBMSs running at the local sites.

Distributed real-time optimistic concurrency control protocol
Proceedings of the 4th International Workshop on Parallel and Distributed Real-Time Systems, 2002Although many recent studies have suggested that optimistic concurrency control (OCC) with dynamic adjustment of serialization order (DASO) is more suitable than two phase locking (2PL) for real-time database systems (RTDBS), most of the protocols proposed for DRTDBS are based on 2PL. When OCC with DASO is extended to DRTDBS, a number of issues have to

Single-site and distributed optimistic protocols for concurrency control
IEEE Transactions on Software Engineering, 1988The authors consider that, in spite of their advantage in removing the overhead of lock maintenance and deadlock handling, optimistic concurrency control methods have been applied less in practice than locking schemes. Two complementary approaches are introduced that may help render the optimistic approach practically viable.

Improving Conflict Detection in Optimistic Concurrency Control Models
2003Configuration Management is required in all software development processes. To support 'agile' methodologies, an approach is desirable that allows developers to work as independently as possible and yet be aware of each other's activities. Optimistic concurrency control provides good support for independent working but is less supportive of ...

Effective optimistic concurrency control in multiversion object bases
1994The use of versioned data has proven its value in many areas of Computer Science including concurrency control. In this paper we examine the use of versioned objects in object bases for the purpose of enhancing concurrency. We provide a framework for discussing multi-version objects which includes fundamental definitions, the abstraction of objects as ...

Optimistic Concurrency Control in Firm Real-Time Databases
2005Concurrency control algorithms for real-time database systems satisfy not only consistency requirements but also meet transaction-timing constraints. Two Phase Locking (2PL) is used often in traditional database systems. However, it has some inherent problems such as the possibility of deadlocks as well as long and unpredictable blocking times ...
