An optimistic approach in distributed database concurrency control

2013 5th International Conference on Computer Science and Information Technology, 2013
In this paper, we present an optimistic concurrency control solution. The proposed solution represents an excellent blossom in the concurrency control field. It deals with the concurrency control anomalies, and, simultaneously, assures the reliability of the data before read-write transactions and after successfully committed. It can be used within the

Optimistic concurrency control in self-organizing networks using automatic coordination and verification

IEEE/IFIP Network Operations and Management Symposium, 2016
In a mobile Self-Organizing Network (SON), the SON coordinator has been introduced to control the application of Configuration Management (CM) changes, in order to prevent conflicts between independent SON function instances running in parallel. However,

Reverse serializability as a correctness criterion for optimistic concurrency control

Microprocessing and Microprogramming, 1994
If buffer retention effect is taken into account, validation schemes for optimistic concurrency control (OCC) should be approached in some different point of view: rather than killing the conflicting transactions immediately in the middle of their execution, it would be better to allow them to run to their completion for bringing the required data ...

An incremental hash-based optimistic concurrency control scenario for failure management in HDDBs - an application approach

International Journal of Intelligent Information and Database Systems, 2015
During real-time transaction process there is a high probability of transaction failure due to the application of various concurrency control-based protocols and network overload.

Less optimism about optimistic concurrency control

[1992 Proceedings] Second International Workshop on Research Issues on Data Engineering: Transaction and Query Processing, 2003
This paper discusses some of the shortcomings of the optimistic concurrency control (OCC) approach in supporting all the features expected in a full-function DBMS. Surprisingly, in spite of OCC having been around for a long time and its performance having been studied in various contexts, no complete system design, let alone a full-blown implementation,

An optimistic multi-level concurrency control for nested typed objects

Twenty-Third Annual Hawaii International Conference on System Sciences, 2002
The authors propose an optimistic multilevel method that also exploits commutativity of typed operations in order to enhance concurrency. One of the main advantages of this method is that it makes it possible to take commutativity depending upon return values into account. A bank-transaction example illustrating the proposed approach is presented. >

Performance analysis of locking and optimistic concurrency control algorithms

Performance Evaluation, 1985
Abstract New analytic models are presented which predict the maximum throughput of locking and optimistic concurrency control algorithms for a centralized database system. By making several simplifying assumptions, these models can be easily solved.

Performance analysis of centralized databases with optimistic concurrency control

Performance Evaluation, 1987
Abstract In this paper we analyze Optimistic Concurrency Control (OCC) schemes based on certification. We allow two data access schemes referred to as static and dynamic . A static data access scheme implies that all data items are accessed at the beginning of transaction processing, while data items are accessed on demand during the processing of

LTPG: Large-Batch Transaction Processing on GPUs with Deterministic Concurrency Control

IEEE International Conference on Data Engineering
GPUs are being applied widely to batch workloads that benefit from the parallel processing capabilities of GPUs. To enable the processing of concurrent batch-based transactions on GPUs, existing systems build dependency graphs during a pre-execution ...

An adaptive strategy integrating locking with optimistic concurrency control

Journal of Computer Science and Technology, 1993
This paper presents an adaptive strategy called K-locking algorithm for concurrency control in database system. The algorithm integrates an optimistic approach with the K-lock mechanism to control the degree of transaction interference. It is shown that the K-locking strategy is adaptive to the changes in transaction parameters and outperforms both an ...
