RETAIN
RETAIN is a mainframe based Database management system, database system, accessed via IBM 3270 terminals (or more likely, emulators), used internally within IBM providing service support to IBM field personnel and customers. The acronym RETAIN stands for Remote Technical Assistance Information Network. Predecessor system Historically, two different, but similar, systems were called RETAIN. The first, dating to the mid-1960s was a system that provided technical information to people in the IBM Field Engineering Division in the form of short bulletins or tips, organized according to machine type number or, for software, according to software component ID number. This information was accessible using simple query commands from IBM service branch office terminals. The terminals supported by this early RETAIN system were typewriter-type terminals, such as the IBM 2740. These same terminals were also used to access the IBM Field Instruction System (FIS), which provided education in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Database Management System
In computing, a database is an organized collection of data stored and accessed electronically. Small databases can be stored on a file system, while large databases are hosted on computer clusters or cloud storage. The design of databases spans formal techniques and practical considerations, including data modeling, efficient data representation and storage, query languages, security and privacy of sensitive data, and distributed computing issues, including supporting concurrent access and fault tolerance. A database management system (DBMS) is the software that interacts with end users, applications, and the database itself to capture and analyze the data. The DBMS software additionally encompasses the core facilities provided to administer the database. The sum total of the database, the DBMS and the associated applications can be referred to as a database system. Often the term "database" is also used loosely to refer to any of the DBMS, the database system or an applicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 3270
The IBM 3270 is a family of block oriented display and printer computer terminals introduced by IBM in 1971 and normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text color on the original models, these terminals are informally known as '' green screen'' terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable. IBM no longer manufactures 3270 terminals, but the IBM 3270 protocol is still commonly used via TN3270 clients, 3270 terminal emulation or web interfaces to access mainframe-based applications, which are sometimes referred to as ''green screen applications''. Principles The 3270 series was designed to connect with mainframe computers, often at a remote location, using the technology then available in the ea ...

Sabre (computer System)
Sabre Global Distribution System, owned by Sabre Corporation, is a travel reservation system used by travel agents and companies to search, price, book, and ticket travel services provided by airlines, hotels, car rental companies, rail providers and tour operators. Originally developed by American Airlines with the assistance of IBM in 1960, the booking service became available for use by external travel agents in 1976 and became independent of the airline in March 2000. Overview The system's parent company is organized into three business units: *Sabre Travel Network: global distribution system *Sabre Airline Solutions: airline technology *Sabre Hospitality Solutions: hotel technology solutions Sabre is headquartered in Southlake, Texas, and has employees in various locations around the world. History The name of the travel reservation system is an abbreviation for "Semi-automated Business Research Environment", and was originally styled in all-capital letters as SABRE. It wa ...

270x
270x is a generic name for a family of IBM non-programmable communications controllers used with System/360 and System/370 computers. The family consisted of the following devices: * IBM 2701 Data Adapter Unit * IBM 2702 Transmission Control * IBM 2703 Transmission Control The 2701 and 2702 were announced simultaneously with System/360 in 1964, the 2703 was announced a year later. The 270x series was superseded by the IBM 3704 and 3705 communications controllers in 1972. 2701 The 2701 supported up to four start-stop or synchronous communications lines. It had two multiplexor channel interfaces for connection to one or two host computers. The synchronous adapter originally supported the ''Synchronous Transmit-Receive (STR)'' protocol, and later ''Binary Synchronous Communications (BISYNC)'' when it was introduced in 1967, in half duplex mode at speeds of up to 40,800 bits per second (bit/s). The 2701 could also have "data acquisition and control adapt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM Program Temporary Fix
In IBM terminology, a Program temporary fix or Product temporary fix (PTF), sometimes depending on date, is a single bug fix, or group of fixes, distributed in a form ready to install for customers. A PTF normally follows an APAR (Authorized Program Analysis Report), and where an "APAR fix" was issued, the PTF "is a tested APAR" or set of APAR fixes. However, if an APAR is resolved as "Fixed If Next" or "Permanent Restriction" then there may be no PTF fixing it, only a subsequent release. PTF installation Initially, installations had to install service via a semi-manual process. Over time, IBM started to provide service aids such as IMAPTFLE and utilities such as IEBEDIT to simplify the installation of batches of PTFs. For OS/360 and successors, this culminated in System Modification Program (SMP) and System Modification Program/Extended (SMP/E). For VM, this culminated in Virtual Machine Serviceability Enhancements Staged (VM/SP SES) and VMSES/E. For DOS/360 and successors, t ...
