Open Mainframe Project is a Collaborative Project managed by the Linux Foundation to encourage the use of Linux-based operating systems and open source software on mainframe computers. [1] The project was announced on August 17, 2015, and was driven by IBM, a major supplier of mainframe hardware, as well as 16 other founding members, that ...
Commercial Linux distributors introduced mainframe editions very quickly after the initial kernel work. IBM manager Karl-Heinz Strassemeyer of Böblingen in Germany was the main lead to get Linux running on S/390. [4] At the start of IBM's involvement, Linux patches for S/390 included some object code only (OCO) modules, without source code. [5]
The name was originally all uppercase because that was the only way to represent it in mainframe code at the time. Both editions of Mike Cowlishaw's first book on the language use all-caps, REXX, although the cover graphic uses mixed case. His book on NetRexx uses mixed case but all caps in the cover graphic with large and small caps, N ET R EXX.
In 2006 Bull HN released the source code for MR12.5, the final 1992 Multics release, to MIT. [23] Most of the system is now available as free software with the exception of some optional pieces such as TCP/IP. [24] In 2014, Multics was successfully run on current hardware using an emulator created by Multicians Harry Reed and Charles Anthony. [25]
Hercules is a computer emulator allowing software written for IBM mainframe computers (System/370, System/390, and zSeries/System z) and for plug compatible mainframes (such as Amdahl machines) to run on other types of computer hardware, notably on low-cost personal computers. Development started in 1999 by Roger Bowler, a mainframe systems ...
Computer Associates Panvalet (also known as CA-Panvalet) is a revision control and source code management system originally developed by Pansophic Systems for mainframe computers [1] such as the IBM System z and IBM System/370 running the z/OS and z/VSE operating systems. [2] CA-PAN/LCM is a similar product for PCs. [1]
The IBM System z Application Assist Processor (zAAP), previously known as the zSeries Application Assist Processor, is a mainframe processor introduced by IBM in 2004. zAAP engines [1] are dedicated to running specific Java and XML workloads under z/OS, accelerating performance. zAAPs are available for zSeries 990 and 890 servers and later zSeries and zEnterprise models.
The Librarian is a version control system and source code management software product originally developed by Applied Data Research for IBM mainframe computers. It was designed to supplant physical punched card decks as a way of maintaining programs, but kept a card model in terms of its interface.
