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 policy decision that is applied initially to QoS reservation requests for controlling the admission of network traffic into the network. Admission control is the process of ensuring that the load on the network links is manageable.<br />(2) The process used by the server to ensure that its bandwidth needs are not compromised by new asset requests.
Industry:Software
(1) A control program that permits functions written for one system or device to be run on another system or device.<br />(2) A program that allows a host system to communicate with a workstation in the same way as it would with the emulated terminal.
Industry:Software
(1) A control section used to reserve a virtual storage area to which other modules can refer.<br />(2) In a Web page that is based on a page template, the fixed region of the page.
Industry:Software
(1) A positive or negative whole number, or zero.<br />(2) In DB2 for i5/OS, a data type indicating that the data is a binary number with a precision of 31 bits.<br />(3) In COBOL, a numeric constant or a numeric data item that does not include any digit position to the right of the assumed decimal point.
Industry:Software
(1) A controller description that emulates the function of a physical controller for communication with a remote device. As an example, when a PC is attached to a system, a virtual controller must be created to allow the PC to communicate with the system.<br />(2) A controller description that is used by Advanced Peer-to-Peer Networking (APPN) and high-performance routing (HPR) support to attach and manage APPN device descriptions. This type of controller does not represent a connection to a remote station.
Industry:Software
(1) A predetermined value, attribute, or option that is assumed when no other value is specified. A default value can be defined for column data in DB2 tables by specifying the DEFAULT keyword in an SQL statement that changes data (such as INSERT, UPDATE, and MERGE).<br />(2) A value that is automatically assigned.
Industry:Software
(1) A primary key or unique key that is used in a referential constraint. The values of a parent key determine the valid values of the foreign key in the constraint.<br />(2) A field or set of fields in a database file that must be unique, ascending, and may or may not contain null values. The parent key may be the same as the primary or unique key.
Industry:Software
(1) A coordinated commitment control process between communicating transactions that ensures that all logically-related updates to recoverable resources are completed or that all are backed out.<br />(2) The cross-site mirroring (XSM) processing that copies data from the production copy to the mirror copy.<br />(3) In Unified Modeling Language (UML), the visual representation of the forks and joins representing parallel workflows. Synchronizations enable you to see a simultaneous workflow in an activity diagram or state chart diagram.<br />(4) The process by which a satellite downloads and runs the same DB2 database commands, operating system commands, and SQL statements from the satellite control server as the other members of its group download and then reports the results to the satellite control server.
Industry:Software
(1) A private volume that contains data that is available for write processing.<br />(2) The first volume assigned to the system storage pool that stores the most critical system metadata.
Industry:Software
(1) A copy of a data entity (a logical volume {LVOL}), for example) that contains the contents of the entire data entity at an instant in time.<br />(2) In a remote copy relationship, a copy of a secondary virtual disk (VDisk) that is identical to the primary VDisk from the viewpoint of a host system, even if a power failure occurred while I/O activity was in progress.
