The name is an acronym for Performance Optimization With Enhanced RISC. [1] The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and supercomputers. These processors are called POWER1 (RIOS-1, RIOS.9, RSC, RAD6000) and POWER2 (POWER2, POWER2+ and P2SC).
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.
One “service unit” originally related to an actual hardware performance measurement (a specific model's instruction performance). However, that relationship disappeared many years ago as hardware and software evolved. MSUs are now like other common (but physically imprecise) measurements, such as “cans of coffee” or “tubes of ...
In 1974 IBM started a project to build a telephone switching computer that required, for the time, immense computational power. Since the application was comparably simple, this machine would need only to perform I/O, branches, add register-register, move data between registers and memory, and would have no need for special instructions to perform heavy arithmetic.
IBM's Hierarchical File System (HFS) is a POSIX-style hierarchical file system [1] for the MVS/ESA/SP through z/OS operating systems.. IBM introduced HFS on February 9, 1993 in MVS/ESA System Product Version 4 Release 3 OpenEdition [2] [3] with DFSMS/MVS Version 1 Release 2 [4] for 3090 mainframes.
SMF data can be collected through IBM Z Operational Log and Data Analytics and IBM Z Anomaly Analytics with Watson. IBM Z Operational Log and Data Analytics collects SMF data, transforms it in a consumable format and then sends the data to third-party enterprise analytics platforms like the Elastic Stack and Splunk, or to the included operational data analysis platform, for further analysis.
In 2015, the four core foundational CICS tools (and the CICS Optimization Solution Pack for z/OS) were updated with the release of CICS Transaction Server for z/OS 5.3. The four core CICS Tools: CICS Interdependency Analyzer for z/OS, CICS Deployment Assistant for z/OS, CICS Performance Analyzer for z/OS and CICS Configuration Manager for z/OS.
In IBM mainframes, Workload Manager (WLM) is a base component of MVS/ESA mainframe operating system, and its successors up to and including z/OS. It controls the access to system resources for the work executing on z/OS based on administrator-defined goals. Workload Manager components also exist for other operating systems.
