In Oracle databases, Flashback tools allow administrators and users to view and manipulate past states of an instance's data without (destructively) recovering to a fixed point in time. Compare the functionality of Oracle LogMiner, which identifies how and when data changed rather than its state at a given time. ==Flash Recovery Area== Flashback requires the Flash Recovery Area (FRA),〔 〕 a storage area that allows Flash Backup and Recovery operations on Oracle databases. DBAs may configure the FRA on an ASM diskgroup or on local disk. It is a specific area of disk storage that is set aside exclusively for retention of backup components such as datafile image copies, archived redo logs, and control-file autobackup copies. The FRA feature is available from release Oracle 10g onwards. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Oracle Flashback」の詳細全文を読む スポンサード リンク
