摘要

事务处理是Web服务能否用于电子商务的关键技术之一.Web服务事务处理必须提供协调短事务和长事务的能力.本文提出了一个能够同时处理原子事务和聚合事务的模型

研究了其协调算法、状态转换及恢复机制.聚合事务允许候选者独立提交

并使用补偿事务来撤销已提交的子事务所带来的影响

可以较好地满足Web服务环境下对长事务的要求

为Web服务投入商用提供了有力支持.

Abstract

Transaction is one of the key technologies whether Web Services can be applied to e-business applications.Transaction technologies for Web Services have to provide the abilities to coordinate short-lived and long-lived transactions.This paper proposes a Web Services transaction model

which can simultaneously handle Atomic transaction and Cohesion transaction

and researches corresponding coordination algorithms

state conversion and recovery mechanisms.Cohesion transaction allows candidates to commit independently

and undoes committed sub-transactions through the compensation transactions so that it can satisfy the requirements for long-lived transaction in Web Services environment

and provide powerful support for commercial web services.
