虚拟存贮存取方法(VSAM)的结构

Virtual Storage Access Method Configuration

虚拟存贮存取方法VSAM是IBM大中型机器操作系统的组成部分,用于虚拟存贮环境中的直接存取存贮器及用虚拟存贮器作输入输出操作的缓冲。VSAM可用于成批处理,联机操作及数据库环境。本文对该存取方法及数据集的结构,作了综合描述。

VSAM (virtual storage access method) is a high performance access method in IBM operating system for direct access storage that runs in virtual storage and uses virtual storage to buffer input and output operations. VSAM supports batch users, online transactions, and data base applications. This paper summarizes the configuration of the access method and data sets.
