O que (quem) é Transaction Processing Facility - definição

IBM MAINFRAME OPERATING SYSTEM USED FOR TRANSACTION PROCESSING

Z/TPF; TPF/ESA; IBM TPF

Transaction Processing Facility

<operating system> (TPF) A real-time mainframe {operating system} released by IBM around 1976. TPF is particularly suited to organisations dealing in very high I/O message switching and large global networks. Current users include British Airways (reservations), VISA International (authorisations), Holiday Inn, and Quantas. TPF was traditionally a 370/Assembler environment although the latest, release 4.1, contains C. Formerly known as ACP (Airline Control Program), it was renamed "TPF" to suggests its greater scope. It is common for TPF sites to use IBM's MVS and VM operating systems for off-line processing. (1996-08-27)

Transaction processing

INFORMATION PROCESSING THAT IS DIVIDED INTO INDIVIDUAL, INDIVISIBLE OPERATIONS

Transaction manager; Credit transaction; Extreme Transaction Processing; Extreme transaction processing

Transaction processing is information processing in computer science that is divided into individual, indivisible operations called transactions. Each transaction must succeed or fail as a complete unit; it can never be only partially complete.

Telecommunication transaction processing systems

Telecommunication networks can generate a vast amount of transactions where each transaction contains information about a particular subscriber's activity. Telecommunication network consist of various interacting devices and platforms.

Transaction Processing Facility

Transaction Processing Facility (TPF) 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 dispersed networks.

While there are other industrial-strength transaction processing systems, notably IBM's own CICS and IMS, TPF's specialty is extreme volume, large numbers of concurrent users, and very fast response times. For example, it handles VISA credit card transaction processing during the peak holiday shopping season.

The TPF passenger reservation application PARS, or its international version IPARS, is used by many airlines. PARS is an application program; TPF is an operating system.

One of TPF's major optional components is a high performance, specialized database facility called TPF Database Facility (TPFDF).

A close cousin of TPF, the transaction monitor ALCS, was developed by IBM to integrate TPF services into the more common mainframe operating system MVS, now z/OS.
