CORBA中对象事务服务研究与实现

介绍了事务概念及其原子性、一致性、隔离性、持久性,阐述了保证事务ACID属性的两阶段提交算法;对CORBA中对象事务服务框架进行了研究,通过对规范中各个对象及其接口的分析,论述了OTS面向对象的分布式事务处理机制;最后给出了服务中事务工厂、控制器、协调者、资源等对象基于可移植对象适配器的实现。

Research and Implementation of Object Transactions Service Based on POA in CORBA

This paper introduces the concept of transaction and its properties, including atomicity, consistency, isolation and durability. The two-phase commit algorithm to guarantee the ACID properties is described. The architecture of object transaction service in CORBA is studied. It also addresses the object oriented mechanism of distributed transactions processing by analysis of the objects and interfaces in the specification, Based on portable object adapter the implementation of most interfaces including transaction factory, control, coordinator and resource is presented.
