Company Profile:
Sometimes referred to as “Big Blue” IBM is a multinational corporation headquartered in Armonk, New York. It manufactures computer hardware and software and provides information technology and services.
(1) A data mapping technique for disc arrays in which fixed-length sequences of virtual-disk data addresses are mapped to sequences of member disc addresses in a regular rotating pattern. See also striped data set.<br />(2) A storage process in which information is split into blocks (a fixed amount of data) and the blocks are written to or read from a series of discs in parallel.
Industry:Software
(1) A programme service provided through a programming interface. See also action service.<br />(2) A set of documented interfaces between the z/OS operating system and higher level applications that want to access functions specified in the Single UNIX Specification and earlier standards.<br />(3) Services that are provided by IMS for use by IMS exit routines. These services provide clearly defined interfaces that allow exit routines to request various functions, such as acquiring storage or finding an IMS control block.
Industry:Software
(1) A data set on direct access storage that contains the log records written by an online IMS system. See also system log data set.<br />(2) A data set on direct access storage that contains the log records written by DBCTL. When the current OLDS is full, DBCTL continues logging to a further available OLDS. See also system log data set.
Industry:Software
(1) A programme statement that specifies an operation to be performed by the computer, along with the values or locations of operands. This statement represents the programmer's request to the processor to perform a specific operation. [OSF]<br />(2) In COBOL, one or more clauses, the first of which starts with a keyword that identifies the instruction. Instructions affect the flow of control, provide services to the programmer, or both.<br />(3) In REXX, one or more clauses that describe some course of action to be taken by the language processor. Instructions may be assignments, keyword instructions, or commands.
Industry:Software
(1) A data set on disc storage that contains queues of messages awaiting transmission to particular terminal operators or to the host system.<br />(2) In PSF, a virtual data set built by the library access system interface (LASI) subcomponent in memory to store error messages for printing at the end of the document.<br />(3) The message data set is used principally to pass messages about the current state of specific resources from the active system to the alternate system. It is also used for the secondary surveillance signals of the active, alternate, or both CICS systems, when the control data set is unavailable for this purpose, either because the last write has not completed yet or because of I/O errors.
Industry:Software
(1) A programme that allows an operator to get information from a disc file.<br />(2) A programme that runs while the system is in inquiry mode.
Industry:Software
(1) A data set or file stored on MVS, in contrast to the view of the file as seen by the workstation.<br />(2) The Virtual Storage Access Method (VSAM) entry-sequenced data set (ESDS) or key-sequenced data set (KSDS) upon which an alternate index is built.
Industry:Software
(1) A programme that causes a computer to act as a workstation attached to another system.<br />(2) A facility of the integration test client that enables the emulation of components and references during module testing. Emulators are either manual or programmatic. See also manual emulator, programmatic emulator.
Industry:Software
(1) A data structure for processing work in which the first element added to the queue is the first element processed. This order is referred to as first-in first-out (FIFO).<br />(2) A line or list of items waiting to be processed; for example, work to be performed or messages to be displayed or transmitted.<br />(3) A WebSphere MQ object to which message queuing applications can put messages, and from which they can get messages.<br />(4) A logical subdivision of the MERVA queue data set used to store the messages associated with a MERVA message-processing function. A queue has the same name as the message-processing function with which it is associated.<br />(5) A sequence with restricted access in which elements can only be added at the back end (or bottom) and removed from the front end (or top). A queue is characterised by first-in, first-out behaviour and chronological order.<br />(6) A WebSphere MQ object that holds messages for message queueing applications. A queue is owned and maintained by a queue manager.<br />(7) A constructed and maintained list of items that are waiting to be processed. A collection of data objects with the same name in a Shared Queue.
Industry:Software
(1) A programme that controls the operation of a communication controller.<br />(2) A programme used for requests and responses exchanged between physical units in a network for data flow control.
