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.
Rexx (restructured extended executor) is a high-level programming language developed at IBM by Mike Cowlishaw. [6] [7] Both proprietary and open source Rexx interpreters exist for a wide range of computing platforms, and compilers exist for IBM mainframe computers. [8] Rexx is used for scripting, application macros and application development.
VM (often: VM/CMS) is a family of IBM virtual machine operating systems used on IBM mainframes System/370, System/390, zSeries, System z and compatible systems, including the Hercules emulator for personal computers.
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 ...
On April 8, 2014, in honor of the 50th anniversary of the System/360 mainframe, IBM announced [23] the release of its first converged infrastructure solution based on mainframe technology. Dubbed the IBM Enterprise Cloud System, [ 24 ] this new offering combines IBM mainframe hardware, software, and storage into a single system and is designed ...
In computing, Interactive System Productivity Facility (ISPF) [1] is a software product for many historic IBM mainframe operating systems and currently the z/OS and z/VM operating systems that run on IBM mainframes.
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.
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.
