(1) A form of access permitted for a file.<br />(2) The manner in which files are referred to by a computer. See also dynamic access, random access, sequential access.<br />(3) One of the modes in which a logical unit (LU) in a disk controller system can operate. The three access modes are image mode, managed space mode, and unconfigured mode. See also unconfigured mode, managed space mode, image mode.
Industry:Software
(1) A serial arrangement of processors or a serial arrangement of registers within a processor. Each processor or register performs part of a task and passes results to the next processor; several parts of different tasks can be performed at the same time.<br />(2) A direct, one-way connection between two or more processes.<br />(3) In printers, the hardware path between the channel station or received-page station and the stacker.<br />(4) A message processing procedure that consists of one or more programs known as stages.
Industry:Software
(1) A form of I/O processing in which DB2 for z/OS initiates multiple concurrent requests for a single user query and performs I/O processing concurrently (in parallel) on multiple data partitions.<br />(2) The process of reading from or writing to two or more I/O devices at the same time to reduce response time.
Industry:Software
(1) A series of commands, combined in a file, that carry out a particular function when the file is run. Scripts are interpreted as they are run.<br />(2) The logical flow of actions for a 3270 server program.<br />(3) An exact text for the telesales service representative to read to a customer regarding transactions. Scripts can be short-hand or prompts to remind a representative to say certain things to a customer at certain points during a call.
Industry:Software
(1) A free-standing structure or frame that can hold multiple servers and expansion units.<br />(2) See enclosure.
Industry:Software
(1) A series of input/output operations that are being done separately from the job that requested them.<br />(2) The nonsequential processing of read and write requests across multiple disks.
Industry:Software
(1) A function of AFP Utilities that maps a database field value to an object name.<br />(2) An object that passes values to the IBM-supplied mapping program. It is used to customize the PDF subsystem without writing a mapping program. See also mapping program, PDF subsystem.
Industry:Software
(1) A series of related inquiries and responses between a user and an application, similar to a conversation between two people.<br />(2) The recorded interaction between a user and the 3270 application that the user accesses. Users can record a dialog using the Record Dialog function in the 3270 terminal service recorder. A recorded dialog includes the keystrokes, inputs and outputs that move the user from one screen to another in the 3270 application.<br />(3) In AIXwindows, a two-way text interface between an application and its user. The interface takes the form of a collection of widgets and gadgets, including a DialogShell widget, a BulletinBoard widget (or a subclass of a BulletinBoard widget or some other container widget), plus various children, including Label, PushButton, and Text widgets.
Industry:Software
(1) A function of DB2 for z/OS that enables applications on different DB2 subsystems to read from and write to the same data concurrently.<br />(2) The ability of multiple host systems to concurrently use data that they store on one or more storage devices. The storage facility enables configured storage to be accessible to any, or all, attached host systems. To use this capability, the host program must be designed to support data that it is sharing.<br />(3) The ability of concurrent subsystems (such as DB2 or IMS DB) or application programs to directly access and change the same data while maintaining data integrity.<br />(4) The concurrent access of databases by two or more IMSs. The IMSs can be in one operating system image or in separate operating system images. They can share data at two levels: the database level and the block level. See also block-level sharing, database-level sharing.
Industry:Software
(1) A server program that processes events.<br />(2) A component of the Common Event Infrastructure that receives events from the event emitters. See also Common Event Infrastructure, event source, event emitter.
