Multiple Virtual Storage, more commonly called MVS, is the most commonly used operating system on the System/370, System/390 and IBM Z IBM mainframe computers. IBM developed MVS, along with OS/VS1 and SVS, as a successor to OS/360. It is unrelated to IBM's other mainframe operating system lines, e.g., VSE, VM, TPF.

IBM mainframes run operating systems supplied by IBM and by third parties. The operating systems on early IBM mainframes have seldom been very innovative, except for TSS/360 and the virtual machine systems beginning with CP-67.

2023年5月3日 · “MVS” stands for “Multiple Virtual Storage”. This (roughly) means that the system can do many “jobs” at one time, and each one of them appears to execute inside its own “personal” region of computer storage. IBM has called the MVS operating system by different names, to show differences in “MVS development stages”.

MVS provides the essential operating system services of z/OS. It includes the I/O Control Program, the z/OS UNIX System Services Kernel, and z/OS XML System Services.

MVS (Multiple Virtual Storage) is an OS from IBM that continues to run on many of IBM's mainframe and large servers. MVS is said to be the OS that keeps the world going. The same could be said of its successor systems, OS/390 and z/OS.

2010年10月20日 · MVS (Multiple Virtual Storage) was first released about 1974 for System/370 machines. It evolved over time into extended architecture as the hardware evolved. Eventually it became part of OS/390, and then z/OS (which is one of …

2006年7月22日 · MVS (Multiple Virtual Storage) is the operating system which is developed by IBM in the sixties and supports POSIX. MVS was developed further from MVT operating system and extended by many functions like the use of virtual memory.

2024年12月26日 · mvs系统使用数据集来模拟一个无限的虚拟存储空间。 虚拟存储是一种抽象，它允许用户使用比实际物理内存大的内存空间。mvs通过虚拟存储管理器（vsm）管理虚拟存储，这个管理器负责将数据集中的数据映射到物理内存中。

OS/390是从一个最近被命名为MVS的系统演化而来的，这种MVS（多 虚拟存储）系统是IBM公司的一种长期的、稳定的大型 主机操作系统。 MVS系统据说可以解决世界上任何一种问题， 工资 、 应收款项 、交易处理、 数据库管理 以及其他针对世界上的大型企业定制的应用程序都可以运行在MVS系统中。 尽管MVS更加类似于一种集中控制的单片机系统，近几年IBM公司还是成功的将其重新定位为大型 服务器系统。 这种大型服务器系统可以应用在面向网络的分布环境中，可以用 …

Describes MVS data areas (group two of four) for system programmers who diagnose and debug operating system and programming problems. It provides information for debugging installation-provided programs or diagnosing IBM-provided programs.
