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) The process of transferring instructions, data, or pages between real storage and external page storage.<br />(2) A technique in which blocks of data, or pages, are moved back and forth between main storage and auxiliary storage. Paging is the implementation of the virtual storage concept.
Industry:Software
(1) The process of undoing uncommitted changes that an application process has made. A backout might be necessary in the event of a failure on the part of an application process or as a result of a deadlock situation. See also roll back, backout free interval.<br />(2) An operation that reverses all changes to resources made during the current unit of work. See also commit, recoverable data set, nonrecoverable data set.<br />(3) See rollback.<br />(4) See rollback.<br />(5) The process of removing all the database updates performed by an application programme that has terminated abnormally. See also dynamic backout.
Industry:Software
(1) The process of writing the same data to two disc units within the same auxiliary storage pool at the same time. The two disc units become a mirrored pair, allowing the system to continue when one of the mirrored units fails.<br />(2) The process of writing the same data to multiple discs at the same time. The mirroring of data protects it against data loss within the database or within the recovery log.
Industry:Software
(1) The process that loads the system programmes from the system auxiliary storage, cheques the system hardware, and prepares the system for user operations.<br />(2) The process of loading the operating system and other basic software into main storage.
Industry:Software
(1) The process whereby stations are invited, one at a time, to transmit.<br />(2) Interrogation of devices for such purposes as avoiding contention, determining operational status, or determining readiness to send or receive data.<br />(3) A feature that allows the Sametime Moderator to send a question to the meeting participants. The Moderator can view the results of the poll and show the results to everyone else in the meeting.
Industry:Software
(1) The processing path that takes the longest time to complete of all parallel paths in a process instance, where each path considered begins at a start node or an input to the process and ends at a stop node.<br />(2) The sequence of activities that determines the earliest date at which a project can be completed. The length of this path changes as activities or tasks are completed earlier or later than the original schedule.
Industry:Software
(1) The processing that a programme performs between synchronisation points.<br />(2) The work that occurs between the start of a transaction and commit or rollback and between subsequent commit and rollback actions. This work defines the set of operations that must be considered part of an integral set.<br />(3) A recoverable unit of work performed within CICS.
Industry:Software
(1) The programme or system to which a request for files or processing is sent.<br />(2) In VisualAge RPG, a part that receives a target event from a source part whenever the state of the source part changes.<br />(3) In SEU, a line command, such as B (Before) or A (After), that specifies the destination for other line commands such as C (Copy) or M (Move).<br />(4) The destination for an action or operation.<br />(5) A collection of logical units (LUs) that are directly addressable on the network. The target corresponds to the server in a client-server model.<br />(6) A storage device on a fibre-channel network.<br />(7) In distributed data management (DDM), the platform that fulfils a request for remote data. A target is also known as a server. See also Distributed FileManager, source.<br />(8) A Small Computer System Interface (SCSI) device that acts as a subordinate to an initiator and consists of a set of one or more logical units (LUs), each with an assigned logical unit number (LUN). The LUs on the target are typically I/O devices. A SCSI target is analogous to an S/390 control unit; a SCSI initiator is analogous to an S/390 channel; and a SCSI LU is analogous to an S/390 device. See also Small Computer System Interface, initiator.<br />(9) A value that a Key Performance Indicator (KPI) should achieve, such as "300" or "5 days."
Industry:Software
(1) The queue onto which the queue manager puts an event message after it detects an event. Each category of event (queue manager, performance, configuration, instrumentation, or channel event) has its own event queue.<br />(2) An ordered list of events.
Industry:Software
(1) The range of addresses available to a computer programme or process. Address space can refer to physical storage, virtual storage, or both. See also allied address space, buffer pool, virtual address space.<br />(2) A range of up to two gigabytes of contiguous virtual storage addresses that the system creates for the user. See also data space.
