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.
All releases of OS/VS2 were available to no charge because the software cost was bundled with the hardware cost. OS/VS2 Release 3.8 was the last free release of MVS. In the late seventies and early eighties IBM announced: 5740-XE1 MVS/System Extensions (MVS/SE) MVS/SE improves the performance and RAS of OS/VS2 (MVS)

On April 6, 1994, IBM introduced MVS/ESA System Product (MVS/ESA SP) Version 5 Release 1, [5] which included MVS OpenEdition (MVS-OE) with HFS as a standard component. IBM continued providing HFS through z/OS 2.4 for z System mainframes. IBM functionally stabilized HFS starting with z/OS 1.7, in 2005. [6] The z/OS File System (zFS) was released ...
Job Control Language (JCL) is a scripting language used on IBM mainframe operating systems to instruct the system on how to run a batch job or start a subsystem. [1] The purpose of JCL is to say which programs to run, using which files or devices [2] for input or output, and at times to also indicate under what conditions to skip a step.
The Job Entry Subsystem (JES) is a component of IBM's MVS (MVS/370 through z/OS) mainframe operating systems that is responsible for managing batch workloads. In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.
Basic Direct Access Method, or BDAM is an access method for IBM's OS/360 and successors computer operating systems on System/360 and later mainframes. BDAM "consists of routines used in retrieving data from, and storing data onto, direct access devices." [1]: p.5 BDAM is available on OS/360, OS/VS2, MVS, z/OS, and related high-end operating ...
IBM Communications Server – Provides Virtual Telecommunications Access Method (VTAM) and TCP/IP communications protocols An additional benefit of the OS/390 packaging concept was to improve reliability, availability and serviceability (RAS) for the operating system, as the number of different combinations of elements that a customer could ...
