Concurrency Control Based on Transaction Clustering
2021 IEEE 37th International Conference on Data Engineering (ICDE), 2021Concurrency control is a mechanism that database systems provide to allow multiple transactions to be executed at the same time while enforcing isolation. The concurrency control algorithm is key to performance of a database system. However, different concurrency control algorithms have different strengths and weaknesses, making each of them fits only ...

Concurrency control of tiered flat transactions
1995In some database systems it has become evident that transactions can consist of a succession of ‘tiers’ where different types of data are being accessed. Despite the different nature of the data accessed by each tier the transactions cannot be split up because of the interdependencies between the albeit different data of the individual tiers.

Concurrency control for step-decomposed transactions
Information Systems, 1999Abstract The throughput of a transaction processing system can be improved by decomposing transactions into steps and allowing the steps of concurrent transactions to be interleaved. In some cases all interleavings are assumed to be acceptable; in others certain interleavings are forbidden.

Java call control, coordination, and transactions
IEEE Communications Magazine, 2000Future telecommunications networks will consist of integrated packet-switched (IP and/or ATM), circuit-switched (PSTN), and wireless networks. Service providers will offer a wide portfolio of innovative applications over these integrated networks. Doing so rapidly and efficiently requires open network APIs, with a key API being that for call control ...

From Transactional Distance to Transactional Control
2007This book offers an exploration of the ways that a learning trajectory is determined, and, in particular, how an online learning environment can affect that trajectory. It provides suggestions about how, primarily through technologies that underlie what is vulgarly known as “Web 2.0,” networked learning environments should be constructed to give ...

A concurrency control scheme for nested transactions
Microprocessing and Microprogramming, 1989Abstract Locking rules for concurrency control in nested transaction model, in which parent/child parallelism, sibling parallelism, and arbitrary commitment-dependence relationship between transactions are allowed, are presented. The locking rules are based on the lock transformation scheme that never allows the commit deadlock to occur, which could ...

Advanced Concurrency Control for Transactional Memory Using Transaction Commit Rate
2008Concurrency control for Transactional Memory (TM) is investigated as a means for improving resource usage by adjusting dynamically the number of concurrently executing transactions. The proposed control system takes as feedback the measured Transaction Commit Rate to adjust the concurrency.

Cautious transaction schedulers with admission control
ACM Transactions on Database Systems, 1985We propose a new class of schedulers, called cautious schedulers , that grant an input request if it will not necessitate any rollback in the future. In particular, we investigate cautious WRW-schedulers that output schedules in class WRW only.

Intangible Controlled Transactions
SSRN Electronic Journal, 2018This paper is about the controlled transactions in the case of intangibles. The intangibles have characteristics which are similar with than of tangibles. Through transfer pricing we have rights which granted from some companies to other, to achieve the appropriate profits and to minimize the losses. The transfer of intangibles allows the allocation of

Concurrency Control for Transactional Composite Services
2009 Congress on Services - I, 2009A composite service can be built from Web Services, and, its workflow can be specified using BPEL4WS. Many composite services are long-running transactional processes. This paper proposes a concurrency control scheme for executing transactional composite services.
