While working on a data problem, Curt, Bill, Ben, Mike, and Matt introduced a vast amount of
corrupted data into the database. Pablo has discovered this problem and he needs you to recover the
database to the point in time prior to the introduction of the corruption. The logical corruption was
introduced at 6:30 p.m. on September 6, 2008. Which of the following would be the correct commands to
use to restore the database to a point in time before the orruption?
A. restore database until time '06-SEP-2008 06:30:00'); recover database until time '06-SEP-2008
06:30:00'); alter database open;
B. restore database until time '06-SEP-2008 06:30:00'); recover database until time '06-SEP-2008
06:30:00'); alter database open resetlogs;
C. restore database until time '06-SEP-2008 18:29:55'); recover database until time '06-SEP-2008 18:29:55'); alter database open resetlogs;
D. restore database until time '06-SEP-2008 18:29:55'); alter database open resetlogs;
E. restore database until time '06-SEP-2008 18:29:55'); recover database; alter database open resetlogs;

　　You would first need to restore the databse to the correct point in time with the
restore database command.You would include the until time parameter to indicate 
what point in time you want to restore to.You then recover the database with the recover 
database command,which will apply the appropriate incremental backups and archived 
redo logs.Again,you use the until time command to indicate the time to recover to.Finally,
you would open the database with the alter database open resetlogs command.
