Yes, I am aware of this hard limit (and how smon_scn_time table is maintained by Oracle ;) FBQ has its limitations. And it has some benefits. For an accidental mess up that is realized soon enough, FBQ may help.

You can't depend on Flashback query for recovery. Even if the undo entries are not overwritten, there is a hard limit of retention. The maximum retention period is 5 days. Actually, the data could be retained for longer, but the SCN - Time map that allows for flashing back has a 5 day limit.

and if they caught the problem within the retention time and if there wasn't a lot of activity that would cause Oracle to overwrite the undo segment anyway... and and and

while I like the idea of flashback query, I'd hate to depend on it for data recovery.
