(1) A service management process that helps to define customer requirements for information technology service availability, the capabilities of the IT infrastructure to deliver those levels of availability, and the actions that are needed to improved availability.<br />(2) In DFSMShsm, the process of ensuring that a current version (backup copy) of the installation's data sets resides on tape or a direct access storage device (DASD).
Industry:Software
(1) A function that exchanges control characters for actual data.<br />(2) A function that expands data to the length that precedes data compression.<br />(3) Process of restoring compressed data to its original state, so that it can be used again.
Industry:Software
(1) A service of a managed resource that includes the sensor and effector that are available to an autonomic manager. The autonomic manager uses the manageability interface to monitor and control the managed resource and any of its managed resources. See also autonomic control loop, effector, management topic, sensor, touchpoint.<br />(2) The composition of one or more manageability capability interfaces. (OASIS)
Industry:Software
(1) A function that is registered by the application programmer to be called by the system or by the application when certain events occur in the system or application.<br />(2) A software routine that controls a program's reaction to specific external events, such as an interrupt handler.<br />(3) In the CICS/ESA Front End Programming Interface (FEPI), a transaction initiated to handle specified events.<br />(4) In Web services, a mechanism for processing service content and extending the function of a JAX-RPC runtime system.

(1) A service that copies inactive files from disc to removable media for longer term storage and removes the files from disc to free disc storage space. The user can select specific objects or groups of objects to include or exclude from the archive process.<br />(2) Persistent storage used for long-term information retention, typically very inexpensive for each stored unit and slow to access, and often in a different geographic location to protect against equipment failures and natural disasters.<br />(3) To copy programs, data, or files to another storage media, usually for long-term storage or security. See also retrieve, storage pool.
Industry:Software
(1) A function that is used to exchange structured data type values in one direction between a DB2 server and host language programs.<br />(2) A DataStage function that computes a value from an original value.
Industry:Software
(1) A session bean with no conversational state. All instances of a stateless bean are identical. (Sun) See also session bean, stateful session bean.<br />(2) A session bean that is a collection of operations. The server can optimise resources by reusing bean instances on every method call.
Industry:Software
(1) A function that permits the sharing of a pool of I/O-related control blocks, channel programs, and buffers among several Virtual Storage Access Method (VSAM) data sets that are open at the same time. See also global shared resource, local shared resource.<br />(2) A software file or plug-in that is stored in a directory and can be shared by packages. See also installation directory.
