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 hardware interface to which an I/O device is attached for the purpose of sending and receiving data.<br />(2) An end point for communication between applications, generally referring to a logical connection. A port provides queues for sending and receiving data. Each port has a port number for identification. See also node.<br />(3) In time-slot management, one end of a 64 kbps unidirectional stream which can be attached to the SCBus.<br />(4) As defined in a Web Services Description Language (WSDL) document, a single endpoint that is defined as a combination of a binding and a network address.<br />(5) The interface between a collaboration and other objects in the WebSphere business integration system. It is through a port that a collaboration object binds with a connector or with another collaboration object. See also binding.<br />(6) The physical entity within a host, SAN Volume Controller, or disk controller system that performs the data communication (transmitting and receiving) over the fibre channel.<br />(7) To modify a computer program that runs on a given platform, to enable it to run on a different system.
Industry:Software
(1) A join method in which a column that is not common to all of the tables being joined becomes part of the resultant table.<br />(2) The result of a join operation that includes the matched rows of both tables that are being joined and preserves some or all of the unmatched rows of the tables that are being joined. See also inner join, join.
Industry:Software
(1) A special character such as an asterisk (*) or a question mark (?) that can be used to represent one or more characters. Any character or set of characters can replace the wildcard character.<br />(2) A character that is used to represent optional characters at the front, middle, or end of a search term. See also masking character.
Industry:Software
(1) A language element that specifies an unchanging value. Constants are classified as string constants or numeric constants.<br />(2) Data that has an unchanging, predefined value to be used in processing.
Industry:Software
(1) A special-purpose buffer storage, smaller and faster than main storage, used to hold a copy of instructions and data obtained from main storage and likely to be needed next by the processor.<br />(2) A buffer that contains frequently accessed instructions and data; it is used to reduce access time.<br />(3) Memory used to improve access times to instructions, data, or both. Data that resides in cache memory is normally a copy of data that resides elsewhere in slower, less expensive storage, such as on a disk or on another network node.<br />(4) To place, hide, or store frequently used information locally for quick retrieval.
Industry:Software
(1) A level set in the system at which a message is sent or an error-handling program is called. For example, in a user auxiliary storage pool, the user can set the threshold level in the system values, and the system notifies the system operator when that level is reached.<br />(2) In OSI, a user-specified value that determines the frequency with which events will be reported. For example, if a certain error threshold is set at 10, the error will not be reported until the tenth occurrence of the error.<br />(3) A customizable value for defining the acceptable tolerance limits (maximum, minimum, or reference limit) for an application resource or system resource. When the measured value of the resource is greater than the maximum value, less than the minimum value, or equal to the reference value, an exception or event is raised. See also performance threshold.<br />(4) A setting that applies to an interrupt in a simulation that defines when a process simulation should be halted based on a condition existing for a specified proportion of occurrences of some event.<br />(5) A storage group attribute that controls the space usage on direct access storage device (DASD) volumes, which is defined as a percentage of occupied tracks versus total tracks.<br />(6) A user-defined entity that establishes a condition or boundary that, if exceeded, causes the data server to take a prescribed set of actions. See also workload definition.
Industry:Software
(1) A lock that limits concurrently running application processes to read-only operations on database data. See also exclusive lock, gross lock.<br />(2) A lock that several tasks can hold.
Industry:Software
(1) A means of preventing uncommitted changes made by one application process from being perceived by another application process and for preventing one application process from updating data that is being accessed by another process. A lock ensures the integrity of data by preventing concurrent users from accessing inconsistent data.<br />(2) The process by which integrity of data is ensured by preventing more than one user from accessing or changing the same data or object at the same time.<br />(3) A mechanism with which a resource is restricted for use by the holder of the lock.<br />(4) A means of serializing a sequence of events or serializing access to data.<br />(5) To temporarily restrict resources to provide protection from concurrent users of the system.
Industry:Software
(1) A measurement of the ability of a system to continue processing without failure. Shutting down an on-line system to process batch updates to the database reduces its availability to end users but has no bearing on the reliability of components required to deliver the online service.<br />(2) The ability of a system to continue to return data even if a component fails.
Industry:Software
(1) A method of starting CICS where all local resources are refreshed, but information relating to remote systems and resource managers is preserved.<br />(2) The process of starting a system or program using an initial program load procedure.<br />(3) A process in which the system is initialized. All jobs that were active or in the job queue at the time of the cold start are removed from the system. See also warm start.<br />(4) A process by which DB2 restarts without processing any log records. See also warm start.<br />(5) The starting of IMS when it is initialized for the first time or when some error condition prevents a warm or emergency restart. See also emergency restart, normal restart.
