(602)On Friday at 11:30 am you decided to flash back the database because of a user error that occurred at 8:30 am.

Which option must you use to check whether a flashback operation can recover the database to the specified time?

A. Check the alert log file

B. Query the V$FLASHBACK_DATABASE_LOG view

C. Query the V$RECOVERY_FILE_DEST_SIZE view

D. Query the V$FLASHBACK_DATABASE_STAT view

E. Check the value assigned for the UNDO_RETENTION parameter

答案:(B)

解析:

我們在做閃回資料庫的時候,查詢V$FLASHBACK_DATABASE_LOG判定你可以閃回的資料庫最早的時間,查詢v$restore_point;可以檢視你有沒有還原點,也有可能成為考點
