All records from all of my tables were removed from database. I didn't use any DELETE method to clear the database. Have you got any idea what could happen? I have never had similar situation before. I tried to retrieve data by following command:
select * from matches as of timestamp systimestamp - interval '24' hour;
but I get error: 01555. 00000 - "snapshot too old: rollback segment number %s with name "%s" too small"
I only add/update records and have no idea how to retrieve data from my tables.
Can someone guide me? Thanks a lot
