The Job Entry Subsystem (JES) is a component of IBM's MVS 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.
z/OS UNIX's predecessor was an operating system component called OpenEdition MVS, first implemented in MVS/ESA SP 4.3 and enhanced in MVS/ESA 5.1. OpenEdition MVS initially only supported the POSIX standards, but X/OPEN, the predecessor to The Open Group, certified MVS/ESA SP V5.1.. IBM continues to enhance UNIX System Services.
With the introduction of MVS in 1974, IBM made it a standard component of their top-end mainframe operating system. TSO/E ("Time Sharing Option/Extensions") is a set of extensions to the original TSO. TSO/E is a base element of z/OS.
On May 19, 1992, IBM announced [10] DFSMS/MVS, 5695-DF1, replacing MVS/Data Facility Product (MVS/DFP) Version 3, 5665-XA3, Data Facility Hierarchical Storage Manager (DFHSM) Version 2, 5665-329 and Data Facility Data Set Services (DFDSS) Version 2, 5665-327. DFSMS/MVS also replaced utilities and service aids.
MVS/370 is a generic term for all versions of the MVS operating system prior to MVS/XA. [ NB 6 ] The System/370 architecture, at the time MVS was released, supported only 24-bit virtual addresses, so the MVS/370 operating system architecture is based on a 24-bit address.
CLIST (Command List) (pronounced "C-List") is a procedural programming language for TSO in MVS systems. It originated in OS/360 Release 20 and has assumed a secondary role since the availability of Rexx in TSO/E Version 2. The term CLIST is also used for command lists written by users of NetView. [1]
In computing, Interactive System Productivity Facility (ISPF) [1] is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes.
OS/390 was introduced in late 1995 in an effort to simplify the packaging and ordering for the key, entitled elements needed to complete a fully functional Multiple Virtual Storage (MVS) operating system package. These elements included, but were not limited to:
