(1) A collection of assertions that describe the allowed states that a managed object can assume. An assertion can be a precondition, a postcondition, or an invariant. In practice, the behavior is often an informal description of the semantics of attributes, operations, and notifications.<br />(2) The way in which managed objects, name bindings, attributes, notifications, and operations interact with the actual resources that they model and with each other.<br />(3) In object-oriented programming, the functionality embodied within a method.<br />(4) The observable effects of an operation or event, including its results.

(1) A named control structure used by an application program to point to and select a row of data from a set. See also insensitive cursor, sensitive cursor, cursor sensitivity, dynamic cursor, static cursor, asensitive cursor.<br />(2) A movable symbol on a display, often a blinking or solid block of light, that identifies a choice to select, indicates where user interaction with the keyboard will appear, or indicates a position of interest on the display surface.<br />(3) A reference to an element at a specific position in a data structure.<br />(4) A displayed symbol that acts as a marker to help the user locate a point in text, in a system command, or in storage. Cursors mark file position and access information in distributed data management (DDM) architecture.<br />(5) During a HALDB online reorganization, a marker in a database partition that separates the copied database records from the records that have not been copied. The cursor indicates the progress of the reorganization through the HALDB partition.

(1) A collection of complete systems that work together to provide a single, unified computing capability.<br />(2) In SNA, a group of stations that consist of a controller (cluster controller) and the workstations attached to it.<br />(3) In high-availability cluster multiprocessing (HACMP), a set of independent systems (called nodes) that are organized into a network for the purpose of sharing resources and communicating with each other.<br />(4) In WebSphere MQ, a group of two or more queue managers on one or more computers, providing automatic interconnection, and allowing queues to be shared amongst them for load balancing and redundancy.<br />(5) In Microsoft Cluster Server, a group of computers, connected together and configured in such a way that, if one fails, MSCS performs a failover, transferring the state data of applications from the failing computer to another computer in the cluster and reinitiating their operation there.<br />(6) A data set defined to VSAM. A cluster can be a key-sequenced data set, an entry-sequenced data set, or a relative record data set.<br />(7) A group of application servers that collaborates for the purposes of workload balancing and failover.<br />(8) A group of two or more Domino servers that provides users with constant access to data, balances the workload among servers, improves server performance, and maintains performance when the size of an enterprise increases.<br />(9) A loosely coupled collection of independent systems (or nodes) organized into a network for the purpose of sharing resources and communicating with each other. See also GPFS cluster.

(1) A named entity within query management that can be assigned a value used for communications between an application program and query management. The entity is accessible from both the application program and query management. See also runtime variable.<br />(2) A symbol defined in one program module that is used in other program modules that are independently compiled.<br />(3) A variable used to contain information for the use of actions. The values of global variables can be extracted from a host screen or elsewhere, and can be used in templates, transformations, macros, Integration Objects, or business logic. A global variable can be a single value or an array, and it can be shared with other applications sharing the same session.<br />(4) A variable that is used to hold and manipulate values assigned to it during translation and that is shared across maps and across document translations. One of the three types of variables supported by the Data Interchange Services mapping command language.<br />(5) A representation of a changeable value that can be accessed and modified by SQL statements that are running within the same session scope. See also special register, variable, session global variable, created global variable, built-in global variable.
Industry:Software
(1) A collection of data objects with the same name that reside on a coupling facility queue structure. Data objects on a shared queue are available to all CQS clients that have access to the structure.<br />(2) In WebSphere MQ for z/OS, a type of local queue. The messages on the queue are stored in the coupling facility and can be accessed by one or more queue managers in a queue-sharing group. The definition of the queue is stored in the shared repository. See also queue-sharing group.
Industry:Software
(1) A named set of disks on which DB2 for z/OS data can be stored.<br />(2) A group that associates a storage system to a storage class. See also storage class, storage system.<br />(3) A collection of storage volumes and attributes that are defined by the storage management subsystem (SMS) administrator to meet a defined service strategy. The collections can be a group of direct access storage device (DASD) volumes; tape volumes; or a group of DASD, optical, or tape volumes treated as a single, object-storage hierarchy. See also tape storage group, virtual input/output storage group, object backup-storage group, object storage group, pool storage group.
Industry:Software
(1) A collection of database objects such as tables, views, indexes, or triggers that define a database. A database schema provides a logical classification of database objects. See also collection.<br />(2) A group of object classes defined for and applicable to a single namespace.<br />(3) See XML schema.<br />(4) See SQL schema.
