The goal of the contest was to provide students with the opportunity to experience working with mainframes. [3] The contest was created in part to increase the number of mainframe skilled individuals in the computing workforce.
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 z/OS operating system (MVS' most recent descendant) also has native support to execute POSIX and Single UNIX Specification applications. The support began with MVS/SP V4R3, and IBM has obtained UNIX 95 certification for z/OS V1R2 and later. [5] The system is typically used in business and banking, and applications are often written in COBOL.
[6] [7] In February 2005, IBM announced z/VSE as successor to VSE/ESA 2.7, which was named to reflect the new System z branding for IBM's mainframe product line. [8] [9] In June 2021, 21st Century Software Inc announced that it had licensed the z/VSE source code from IBM with the intention of developing new versions of the operating system. [10]
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.
International Business Machines (IBM) used to dominate the computer industry -- especially in the 1960s when mainframe computers were the only game in town. During the 1970s, that dominance gave ...
IBM next-gen mainframe will be powered by the Telum II processor. Each chip features eight CPU cores, a large pool of fast cache memory, and a built-in AI accelerator meant for inferencing workloads.
Transaction Processing Facility (TPF) [2] is an IBM real-time operating system for mainframe computers descended from the IBM System/360 family, including zSeries and System z9. TPF delivers fast, high-volume, high-throughput transaction processing, handling large, continuous loads of essentially simple transactions across large, geographically ...
