ORA-01555 Snapshot too old, rollback segment too small after flashback tab
797985Nov 12 2010 — edited Nov 12 2010Hello
Further to an update on a table in database, I realize that I have done an error and I want to come back in the state of table before this operation.
For this I use 'Flashback table' as this command :
flashback table 'table_name' to timestamp to_timestamp('2010-11-08 08:00:00 AM','YYYY-MM-DD HH:MI:SS PM')
and I get this error :
ORA-01555 :Snapshot Too Old rollback segment N° x , "_SYSSMU9$", too small
What I can do to not have this problem ? can I avoid it ?
Please helps .
Regards
