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.
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.
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.
Input/Output Configuration Program (IOCP) [4] [5] [6] is a program for IBM mainframes that compiles a description of the Channel Subsystem and LPAR [7] configuration, optionally loading it into an Input/Output Configuration Data Set (IOCDS); it recognizes the syntax of MVS Configuration Program (MVSCP) [8] input, and there is no need to ...
As it is an assembly language, BAL uses the native instruction set of the IBM mainframe architecture on which it runs, System/360.. The successors to BAL use the native instruction sets of the IBM mainframe architectures on which they run, including System/360, System/370, System/370-XA, ESA/370, ESA/390, and z/Architecture.
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 ...
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.
CLIST can read/write MVS files and read/write from/to a TSO terminal. It can read parameters from the caller and also features a function to hold global variables and pass them between CLISTs. A CLIST can also call an MVS application program (written in COBOL or PL/I, for example). CLISTs can be run in background [ii] [iii].
