Designing concurrent and distributed control systems
Communications of the ACM, 1996After a decade of real-world experiences, the applicability of the G++ pattern language is well documented.

The Complexity of Distributed Concurrency Control
SIAM Journal on Computing, 1981We present a formal framework for distributed databases, and we study the complexity of the concurrency control problem in this framework. Our transactions are partially ordered sets of actions, as opposed to the straight-line programs of the centralized case. The concurrency control algorithm, or scheduler, is itself a distributed program.

Two fully distributed concurrency control algorithms
IEEE Transactions on Knowledge and Data Engineering, 1993Two new concurrency control algorithms are introduced for partially replicated distributed databases. They both maintain two values of a data item, and differ in that one requires all locks to be granted at one time, whereas the other does not. They are based on locking, and avoid deadlocks by using timestamps to establish an execution order when ...

Asynchronous operations in distributed concurrency control
IEEE Transactions on Knowledge and Data Engineering, 2003Distributed locking is commonly adopted for performing concurrency control in distributed systems. It incorporates additional steps for handling deadlocks. This activity is carried out by methods based on wait-for-graphs or probes. The present study examines detection of conflicts based on enhanced local processing for distributed concurrency control ...

Concurrency control in distributed database system
2016 International Conference on Computer Communication and Informatics (ICCCI), 2016Concurrency manipulates the control of concurrent transaction execution. Distributed database management system enforce concurrency manipulate to make sure serializability and isolation of transaction. Lots of research has been done on this area and a number of algorithms have been purposed.

`PRABHA'---a distributed concurrency control algorithm
Proceedings of the 1990 ACM annual conference on Cooperation - CSC '90, 1990We propose a non-preemptive, deadlock free concurrency control mechanism for distributed database systems. The algorithm uses a combination of transaction blocking and roll-back to achieve serialization. Unlike other locking mechanisms presented in the past, the algorithm proposed here uses dynamic attributes of transactions to resolve conflicts to ...

An evaluation of distributed concurrency control
Proceedings of the VLDB Endowment, 2017Increasing transaction volumes have led to a resurgence of interest in distributed transaction processing. In particular, partitioning data across several servers can improve throughput by allowing servers to process transactions in parallel. But executing transactions across servers limits the scalability and performance of these systems. In

System Level Concurrency Control for Distributed Database Systems
ACM Transactions on Database Systems, 1978A distributed database system is one in which the database is spread among several sites and application programs “move” from site to site to access and update the data they need. The concurrency control is that portion of the system that responds to the read and write requests of the application programs.
