3 manières de faire :

 

SQL> flashback database to TIMESTAMP(sysdate – 2/24); –> flash back to 2 hr
SQL> FLASHBACK DATABASE TO TIMESTAMP SYSDATE-(1/24/12); –> Flashback 5 minutes.
SQL> flashback database to timestamp to_date(’27-JUN-2016 19:50:00′,’DD-MON-YYYY HH24:MI:SS’); –> flash bakc to a specific time period
