基于COM/COM+的多进程数据共享接口

Multi-threaded Data-shared Interface Based on COM/COM+

在COM /COM +组件技术的应用中 ,由多个组件接口对象共享一个数据空间带来了对共享数据的并发控制及提高其性能的问题。本文通过对COM /COM +的同步机制的分析 ,指出在不同情况下数据共享池设置及其访问接口设计应注意的问题 ,并借助阅读者 /写入者问题为例 ,提出数据共享池接口组件的设计方案。

This article discusses the concurrency issue and its performance,when the multi component interface objects share a data section. In this paper,the Synchronic mechanism of COM/COM+ has been analyzed. And the problems that should be noted in the design of the data shared pool and its interface,has been pointed out. The designing scheme of data shared interface component about the readers/writers problem,has also been described,
