(1) In the GDDM function, a directed line segment, which is a straight line between two points.<br />(2) In SNA, a data structure containing three fields: a length field that specifies the length of the vector in which it is contained, an identifier or type field, and a value field. The value field may contain subvectors.<br />(3) An array of one dimension.<br />(4) A linearly ordered collection of scalars of the same type. Each scalar is said to be an element of the vector. See also array, scalar.

(1) A terminal attached to a system through a data link.<br />(2) A terminal that is not attached to the host system through an I/O channel.

(1) In a remote journal network, pertaining to the processing that is performed by a hot-backup application to logically promote a backup system to assume the role of a primary system.<br />(2) A cluster event where the primary database server or application server switches over to a backup system due to the manual intervention from the cluster management interface.
Industry:Software
(1) In SQL replication, the updated content of a source-table column that is recorded in a change data (CD) table or in a database log or journal. See also before-image.<br />(2) The contents of a record in a physical file after the data is changed by a write or an update operation.<br />(3) A record of the contents of a data element after it has been changed. After-images are used for forward recovery.<br />(4) A business object that contains all of an entity's data after changes have been made to it during an update operation. An after-image contains the complete business object rather than only the primary key and those elements that were changed. See also delta business object.

See also input parameter, system variable.<br />(2) A variable unique to the map it is defined in (it is not shared across maps) and one of the three types of variables supported by the Data Interchange Services mapping command language.

(1) In the GDDM function, a rectangular area within the picture space that defines where the output of the current page appears on the work station.<br />(2) That portion of a partition or usable area defined for display of data to the operator. The viewport has a predefined size and position on the screen and is related to a presentation space through a specified window. See also presentation space.<br />(3) In BMS, that part of a screen that is allocated to a partition. See also partition.
Industry:Software
(1) A test that checks attachment or controller circuitry (without checking the connected device) by returning the output of the attachment of controller circuitry as input. For example, when irrecoverable communications adapter or machine errors occur, the wrap test can transmit a specific character pattern to or through the modem in a loop and then compare the character pattern received to what was transmitted.<br />(2) For devices, a diagnostic test that returns the output of a device as input.
Industry:Software
(1) In a remote journal network, the process of replicating journal entries that existed in the journal receivers of the source journal before the remote journal was activated.<br />(2) In XRF, a process in which the active CICS system uses CAVM message services to send a stream of messages describing the current state of all its VTAM terminals, to the message data set and thence to the alternate CICS system.

(1) In SQL, a number that represents an interval of time.<br />(2) In Backup, Recovery, and Media Services, the length of time that the designated media is to reside at a location before moving to the next location or returning to the home location. A duration is specified in the move policy.
