2. IBM Z - Wikipedia

   en.wikipedia.org/wiki/IBM_Z

   The typical ordering process of modern IBM Z mainframe looks like a buying of service [50] or looks like a leasing; [51] the mainframe is a program/hardware complex with rent for a system workload, and (in the most cases) additional system capabilities can be unlocked after additional payment.

3. z/Architecture - Wikipedia

   en.wikipedia.org/wiki/Z/Architecture

   Linux also supports z/Architecture with Linux on IBM Z. z/Architecture supports running multiple concurrent operating systems and applications even if they use different address sizes. This allows software developers to choose the address size that is most advantageous for their applications and data structures.

4. Input/Output Configuration Program - Wikipedia

   en.wikipedia.org/wiki/Input/Output_Configuration...

   Starting with System z9 running z/OS 1.7, IBM offered the multiple-subchannel set facility, which allowed up to four independent sets of 64 Ki subchannels. [ 3 ] The installation was responsible for defining the Input/Output Configuration Data Set s ( IOCDS' s), and the operator could select a specific IOCDS as part of a power on reset (POR).

5. Master the Mainframe Contest - Wikipedia

   en.wikipedia.org/wiki/Master_the_Mainframe_Contest

   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.

6. IBM mainframe - Wikipedia

   en.wikipedia.org/wiki/IBM_mainframe

   The primary operating systems in use on current IBM mainframes include z/OS (which followed MVS/ESA and OS/390 in the OS/360 lineage), z/VM (which followed VM/ESA and VM/XA SP in the CP-40 lineage), z/VSE (which is in the DOS/360 lineage), z/TPF (a successor of Transaction Processing Facility in the Airlines Control Program lineage), and Linux ...

7. IBM Basic assembly language and successors - Wikipedia

   en.wikipedia.org/wiki/IBM_Basic_assembly...

   As it is an assembly language, BAL uses the native instruction set of the IBM mainframe architecture on which it runs, System/360, just as 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.

8. z/OS - Wikipedia

   en.wikipedia.org/wiki/Z/OS

   An IBM System Z10 mainframe computer on which z/OS can run. z/OS is a 64-bit operating system for IBM z/Architecture mainframes, introduced by IBM in October 2000. [2] It derives from and is the successor to OS/390, which in turn was preceded by a string of MVS versions.

9. Job Entry Subsystem 2/3 - Wikipedia

   en.wikipedia.org/wiki/Job_Entry_Subsystem_2/3

   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.
