Timestamp Based Optimistic Concurrency Control
TENCON 2005 - 2005 IEEE Region 10 Conference, 2005Optimistic concurrency control demonstrates a few improvements over pessimistic concurrency controls like two-phase locking protocol or time-stamp based protocol. But the price of coarse detection of conflicts may sometimes be high and consequently discounts the advantage of optimistic concurrency control protocol.

Timestamp Based Concurrency Control in Broadcast Disks Environment
Autonomous Intelligent Systems, 2005Broadcast disks are suited for disseminating information to a large number of clients in mobile computing environments. In this paper, we propose a timestamp based concurrency control (TCC) to preserve the consistency of read-only client transactions, when the values of broadcast data items are updated at the server.

A Timestamp-Based Optimistic Concurrency Control for Handling Mobile Transactions
Communication Systems and Applications, 2006Data broadcasting is an efficient method for disseminating data, and is widely accepted in the database applications of mobile computing environments because of its asymmetric communication bandwidth between a server and mobile clients. This requires new types of concurrency control mechanism to support mobile transactions executed in the mobile ...

Distributed Logical Timestamp Allocation for DBMS Concurrency Control on Many-core Machines
IEEE International Symposium on High-Performance Parallel Distributed Computing, 2023We investigate the timestamp allocation scheme in classical concurrency controls of the database management systems (DBMS) on many-core machines. Then we discuss a distributed logical timestamp allocation scheme with uniqueness and fairness to improve ...

2008 IEEE International Symposium on Defect and Fault Tolerance of VLSI Systems, 2008
This paper presents a concurrent error detection technique for the control logic of a modern microprocessor. Our method is based on execution time prediction for each instruction executing in the processor. To evaluate the proposed method, we use a superscalar, dynamically-scheduled, out-of-order, Alpha-like microprocessor, on which we execute SPEC2000

Focus! Fast On-disk Concurrency-control Using Sketches
Proc. ACM Manag. DataConcurrency-control (CC) mechanisms are essential for ensuring consistency in large-scale key-value stores, but traditional approaches face significant challenges. Mechanisms like 2PL and OCC incur high CPU overheads.

Concurrency Control in Distributed Database System: Solution of the Anomalies & Challenges
International Conferences on Computing AdvancementsMaintaining concurrency among the transactions can become a challenge in a database system while assuring data integrity and consistency. Data concurrency refers to the control mechanism among multiple transactions such that every transaction appears as ...
