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 process of re-creating a database or table space that became unusable because of hardware failure, software failure, or both. The process includes restoring a backup image and can also include rolling database logs forward in time.<br />(2) In Backup, Recovery, and Media Services, the process of locating and restoring data in the event of partial or total data destruction. The recovery service automatically locates the correct media to be restored based on user-defined media management and recovery requirements.<br />(3) The process of returning the system to a state from which operation can be resumed.<br />(4) The restoration of resources following an error.<br />(5) The process of rebuilding data after it has been damaged or destroyed, often by using a backup copy of the data or by reapplying transactions recorded in a log.<br />(6) The process of restoring access to file system data when a failure has occurred. Recovery can involve reconstructing data or providing alternative routing through a different server.
Industry:Software
(1) The process of restoring a database after a partial or complete site failure that was caused by a catastrophic event such as an earthquake or fire. Typically, disaster recovery requires a full database backup at another location.<br />(2) A procedure for copying and storing an installation's essential data in a secure location, and for recovering that data in the event of a catastrophic problem. See also vital records.
Industry:Software
(1) The process of restoring a physically or logically damaged DBDS by merging an image copy and logs or change accumulation data sets.<br />(2) The function of restoring the user data sets, starting with a backup copy and applying all changes made to each data set after the backup was taken.
Industry:Software
(1) The process of restoring data that was changed by an application program or user.<br />(2) See backout.<br />(3) In CICS, the cancellation by an application program of the changes it has made to all recoverable resources during the current logical unit of work.<br />(4) The execution of a scenario's compensation steps by InterChange Server to undo the effects of a partially completed scenario.<br />(5) An operation in a transaction that reverses all the changes made during the unit of work. After the operation is complete, the unit of work is finished.<br />(6) The process of restoring data that was changed by SQL statements to the state at its last commit point. All locks are freed.
Industry:Software
(1) The process of restructuring a data model by reducing its relations to their simplest forms. It is a key step in the task of buildinga logical relational database design. Normalization helps avoid redundancies and inconsistencies in data. An entity is normalized if it meets a set of constraints for a particular normal form (first normal form, second normal form, and so on). See also denormalization, repeating group.<br />(2) The process of replacing surface form representations with their canonical form. This may include case normalization, where a capitalized word is replaced by a lowercase word: 'Run' becomes 'run'; grammatical normalization, where an inflected verb is replaced by the non-inflected form: 'runs' becomes 'run'; lexicographical normalization, where Unicode full-width characters is replaced with Unicode basic form, or white spaces are removed from Chinese text.<br />(3) The conversion of records that contain multivalued data from nonfirst-normal format (NF2) into one or more first normal format (1NF) rows.
Industry:Software
(1) The process of returning a file to a particular point by removing journaled changes to the file.<br />(2) The process of removing changes that are possibly inconsistent. For example, backout recovery will delete an update that has been requested if the program fails before requesting a related update. Backout recovery requires a log to hold images of records before they were updated. See also forward recovery.
Industry:Software
(1) The process of returning to a previous release of DB2 for z/OS after attempting or completing migration to a current release. Fallback is supported only from a subsystem that is in compatibility mode.<br />(2) The process of automatically switching back to the original database server after failure caused a switch to an alternative database server.
Industry:Software
(1) The process of sending the subsections of a request to the specific database partition that contains the applicable data.<br />(2) The process, transparent to the application program, by which CICS accesses resources when those resources are actually held on another CICS system.
Industry:Software
(1) The process of setting up and maintaining a user's access to a system.<br />(2) The process of configuring servers, software, networks, and storage resources.
