how long back can oracle query flashback
spur230Nov 12 2009 — edited Nov 13 2009Hi Everybody,
I am using Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi.
The database has undo_retention value of 14400 which is 4 hours.
However , I can flashback any table upto 5 days back.
select * from tablename as of timestamp sysdate -5
When I flashback sysdate -6 it give me error no snapshot found.
I want to now what parameter in database determines how long back I can flash back?
Any help is greatly appriciated.
