A METHOD FOR RECOVERING LOGICAL DATA ERRORS IN DATABASE

摘要

PURPOSE: A method for recovering logical data errors in data base is provided to reduce a time for receiving logical data errors by rapidly searching transactions with the logical data errors. CONSTITUTION: Database(1) generates Redo-log files(2) with respect to results for processing the requirement of a user. An archived redo-log file(3) is generated from the redo-log films in a full state. A system server agent(4) is in connection with the database. The system server agent extracts new data from the redo-log files based on the requirement of the user. Index and log data(5) are generated based on transaction. A system client(6) downloads the index data through FTP.
