2. History of IBM mainframe operating systems - Wikipedia

   en.wikipedia.org/wiki/History_of_IBM_mainframe...

   All modern IBM mainframe operating systems except z/TPF are descendants of those included in the "System/370 Advanced Functions" announcement – z/TPF is a descendant of ACP, the system which IBM initially developed to support high-volume airline reservations applications.

3. 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 ...

4. 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.

5. IBM Z - Wikipedia

   en.wikipedia.org/wiki/IBM_Z

   The z15, z14, z13, zEC12, zBC12, z114 and z196 support the IBM operating systems: z/OS, z/VM, z/VSE, and z/TPF. Other operating systems available include Linux on IBM Z , such as Red Hat Enterprise Linux 6 and SUSE Linux Enterprise Server 11 . [ 52 ]

6. MVS - Wikipedia

   en.wikipedia.org/wiki/MVS

   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.

7. Mainframe computer - Wikipedia

   An example of such a system is the HITAC S-3800, which was instruction-set compatible with IBM System/370 mainframes, and could run the Hitachi VOS3 operating system (a fork of IBM MVS). [39] The S-3800 therefore can be seen as being both simultaneously a supercomputer and also an IBM-compatible mainframe.

8. OS/390 - Wikipedia

   en.wikipedia.org/wiki/OS/390

   OS/390 is an IBM operating system for the System/390 IBM mainframe ... and the result is now named z/OS. IBM ended support for the older OS/390-branded versions in ...

9. Transaction Processing Facility - Wikipedia

   en.wikipedia.org/wiki/Transaction_Processing...

   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 ...
