Permit Based Locking
نویسنده
چکیده
The Permit based Locking design pattern provides fast acquisition and release of locks without network communication even in distributed systems build around a central lock server. Instead of plain locks, the server manages "permits to lock", and passes them to those clients which probably need the lock next. If a client hosts a permit, the associated lock can be acquired immediately without server interaction. If a permit asked for is not present at the server but at some other client, it can be revoked.

Optional and Responsive Fine-Grain Locking in Internet-Based Collaborative Systems
Locking is a standard technique in distributed computing and database systems used to ensure data integrity by prohibiting concurrent conflicting updates on shared data objects. Internet-based collaborative systems are a special class of distributed applications which support human-to-human interaction and collaboration over the Internet. In this paper, a novel optional and responsive fine-grai...
متن کاملEvaluation of Phase Locking and Cross Correlation Methods for Estimating the Time Lag between Brain Sites: A Simulation Approach
Introduction: Direction and latency of electrical connectivity between different sites of brain explains brain neural functionality. We compared efficiency of cross correlation and phase locking methods in time lag estimation which are based on local field potential (LFP) and LFPspike signals, respectively. Methods: Signals recorded from MT area of a macaque’s brain was used in a simulation ...

متن کاملHierarchical locking in B-tree indexes
Three designs of hierarchical locking suitable for B-tree indexes are explored in detail and their advantages and disadvantages compared. Traditional hierarchies include index, leaf page, and key range or key value. Alternatively, locks on separator keys in interior B-tree pages can protect key ranges of different sizes. Finally, for keys consisting of multiple columns, key prefixes of differen...
متن کاملThe Transient Behavior of LC and Ring Oscillators under External Frequency Injection
In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...
