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 part of the operating system that controls the storing and accessing of data to or from an application program. The data can be on internal storage (for example, database), on external media (diskette, tape, or printer), or on another system.<br />(2) The task of systematically identifying, organizing, storing, and cataloguing data in an operating system.
Industry:Software
(1) The part of the service function used to service the system when the operating system is not running.<br />(2) Service functions that are available only from the console and can run when the operating system is not available, as well as when the operating system is available.
Industry:Software
(1) The parts of a program's executable code, data areas, or both that are being used intensively and are therefore important to keep in the fastest possible type of storage. Thus a program's instruction cache working set is the set of programme cache lines that need to be kept in the instruction cache if the programme is to run at maximum speed.<br />(2) The amount of real storage required in order to avoid excessive paging.
Industry:Software
(1) The passing of a message from one process to another. For example, Distributed Relational Database Architecture (DRDA) flows are those that consist only of messages described by the DRDA protocol as part of the DRDA protocols.<br />(2) A single transmission of data passing over a link during a conversation.
Industry:Software
(1) The path information units (PIUs) that can be transmitted on a virtual route before a virtual-route pacing response is received, indicating that the virtual route receiver is ready to receive more PIUs on the route.<br />(2) The requests that can be transmitted on the normal flow in one direction on a session before a session-level pacing response is received, indicating that the receiver is ready to accept the next group of requests.
Industry:Software
(1) The permanent destination data set for IMS log records. The SLDS is usually on tape or MSS. In an IMS batch region, the SLDS is created at execution time. In an IMS online region, the SLDS is created by copying the online log data set to it by means of the Log Archive utility. See also online log data set, write-ahead data set.<br />(2) A data set on which IMS archives a full online log data set (OLDS). An SLDS can be on DASD or tape. The contents are used as input to the database recovery process. See also online log data set.
Industry:Software
(1) The person who controls and manages a computer system.<br />(2) In OSI, a person who controls how the open system resources of a system or enterprise are used.<br />(3) A DB2 database user with administrative authority. In DB2 Database for Linux, UNIX, and Windows, this authority is SYSADM. In DB2 for i5/OS, this authority is *ALLOBJ authority. In DB2 for z/OS, this authority is SYSADM.
Industry:Software
(1) The physical enclosure containing the tape drive.<br />(2) A tape device or a robotics controller that is visible over a storage network. A tape unit is a member of a single storage network (of 1 - n fabrics), but can have 1 - n equivalent paths. See also tape device.
Industry:Software
(1) The physical or logical mapping of the location of networking components or nodes within a network. Common network topologies include bus, ring, star, and tree.<br />(2) In the broker domain, the brokers, collectives, and connexions between them.<br />(3) An inventory of CICS and CICSPlex SM resources, and a map of their relationships. CICSPlex SM supports the definition of resource and system topology.<br />(4) In fibre-channel technology, the configuration of the fibre-channel network and the resulting communication paths allowed. Possible topologies are point-to-point, switched fabric, and arbitrated loop.<br />(5) A graphical breakdown of a transaction displayed in an hierarchical arrangement of software components and transactions.<br />(6) A graphical view of a configured item and its relationships.
Industry:Software
(1) The physical path in data transmission.<br />(2) On a terminal, one or more characters entered before a return to the first printing or display position, or accepted by the system as a single block of output.
