1)
Flashback Database can only undo changes to a datafile made by an Oracle database.
If any media failure occurs in database then flashback database can’t be used.
That means if a datafile is dropped then you can’t use flashback feature.

2)
If you have shrink your any datafile then flashback database can’t be used.

3)
If the database control file is restored from backup or re-created,
then you cannot use FLASHBACK DATABASE to return to a point in time
before the restore or re-creation of a control file.

4)
