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).
The z196 microprocessor [1] is a chip made by IBM for their zEnterprise 196 and zEnterprise 114 mainframe computers, announced on July 22, 2010. [2] The processor was developed over a three-year time span by IBM engineers from Poughkeepsie, New York; Austin, Texas; and Böblingen, Germany at a cost of US$1.5 billion. [3]
Many of the early users of PCs were mainframe programmers or users, who were accustomed to and liked the ISPF panel system. This led several companies to create partial clones of ISPF that run on DOS, OS/2, Windows or Unix PC systems. In 1984 IBM introduced the EZ-VU dialog manager for DOS PCs, [13] [14] and later OS/2.
The POWER2 was a multi-chip design, but IBM also made a single chip design of it, called the POWER2 Super Chip or P2SC that went into high performance servers and supercomputers. At the time of its introduction in 1996, the P2SC was the largest processor with the highest transistor count in the industry and was a leader in floating point ...
RACF (IBM's mainframe security software product) – Sysplex-wide RVARY and SETROPTS commands; PDSE file sharing; Multisystem VLFNOTE, SDUMP, SLIP, DAE; Resource Measurement Facility (RMF) – Sysplex-wide reporting; CICS – uses XCF to provide better performance and response time than using VTAM for transaction routing and function shipping.
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 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.
Resource Measurement Facility (RMF) is a performance monitor for the z/OS Operating System. It also collects data for long-term performance analysis and capacity planning. The product consists of the following components: Monitor I Data Gatherer which collects data in adjustable intervals from one minute to one hour. The data is written to SMF ...
