concurrency control method meaning in English

并行性控制方法

Traditional concurrency control methods can ’ t be well applied to resolve these problems in a loosely - coupled environment . the application constructor has no central control on resources provided by autonomous business entities . since the business process is long - running , the providers may not be willing to lock resources exclusively for such long period , and serialization by locking resource will raise serious scalability issues
传统的并发控制方法并不完全适应web服务环境下松耦合应用集成的特点,主要表现在:资源是自治的,无法对来自不同提供者的资源进行集中控制;业务流程的复杂性使流程的执行跨越较长的时间,一方面资源提供者可能不愿意长时间地锁定资源,另一方面运用加锁等串行化方法将导致并发度降低,严重影响利用效率。
This paper analysis the shortage of traditional concurrency control method in multidatabase and brings froward a new concurrency control algorithm . we also bring forward a new recovery method for multidatabase : synthesis 2pc protocol , which combines many multidatabase recovery methods into one algorithm , and makes the algorithm more useful and more efficient
本文还提出了一种新的多库系统恢复机制：综合2pc协议，它把已有的几种多库系统恢复机制结合在一个算法中使用，使其更适于多库系统的异构性，应用范围更为广泛，效果也更好。
