提高VSAM文件访问速度的一种有效方法

An Efficient Approach for Improving VSAM File Access Speed

文章针对当前主机系统所面临的效率问题,提出减小CA分裂次数,加快VSAM文件访问速度的有效方法,以此来提高系统运行效率。文章先对VSAM结构进行介绍,然后详细描述减小CA分裂的方法,最后通过实际应用中的测试,证明该方法行之有效,并可以大大的提高主机系统运行的效率。

To solve the efficiency problem of current mainframe systems,we present an approach for improving VSAM file access speed.In this paper,we intruduce the VSAM structure and explain the approach of reducing CA splitting. With the experiment and test in real applications,the approach is proven to be eddicient and feasible.
