| 摘 要： | 分布对象事务管理中,通过事务上下文使事务性操作与特定事务发生关联.传统的显式上下文传播方式实现简单,但对应用开发者要求较高,且不易进行分布事务管理的功能扩展.基于CORBA中间件平台及其截获器技术,设计并实现了一种灵活有效的事务上下文传播的方法ITCPM,文中详细介绍了其工作原理以及关键算法的实现.

| Abstract: | Transaction context uniquely associates a transactional operation with a given transaction in distributed object transaction management. Traditional explicit context propagation mode is difficult for application developers to use and is not ready for function extension of distributed transaction management system. Based on the CORBA platform StarBus and its Portable Interceptor mechanism, we propose ITCPM, a novel mode which makes transaction context propagation easier to use. ITCPM is flexible for the users and is at the same time efficient. We show in detail how ITCPM is designed and implemented. StarOTS, our transaction management service supporting ITCPM, has been widely used into areas such as finance, etc. |
