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).
Generally, these panels just provide a convenient interface to do tasks—most of them execute modules of IBM mainframe utility programs to do the actual work. ISPF is frequently used to manipulate z/OS data sets via its Program Development Facility (ISPF/PDF). [3] ISPF is user-extensible and it is often used as an application programming ...
OMEGAMON, later IBM Tivoli OMEGAMON XE, is a software family of performance monitors for IBM zEnterprise computer environments. These products were originally written, marketed, sold and maintained by Candle Corporation, [1] which was acquired by IBM in 2004.

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.
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.
A Honeywell Level 66/60 mainframe computer with its cabinet door open. 6000-series systems were said to be "memory oriented" — a system controller in each memory module arbitrated requests from other system components (processors, etc.).
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.
