Just earlier I was also recovering a "critical test database" with no backup and in "noarchivelog mode" But my case was different, my current redo log group had a corrupted block.. and yes I also used the _allow_restlogs_corruption = true then when I opened my database the UNDO tablespace datafile also had a corrupted block... I was able to fix it by making the undo_management=manual and create a new UNDO tablespace. I've documented it all here.. it will redirect you to a forum: Redo and Undo Corruption http://karlarao.tiddlyspot.com/#%5B%5BRedo%20and%20Undo%20Corruption%5D%5D Also, have they tried to re-login again? and still got the ORA-01033?
