I am getting thes messages while trying to recover a database. The drive died and we had to restore to a different box, but we do not have any controlfiles or redo logs. I do have the datafile up to a certain point in. This database was not backed up. I need some help because when I try to create the controlfile it gives me a create controlfile failed error. I am starting the database in a nomount mode and it tells me the database is already mounted and the latest error is ORA-1507 database not mount when I try to backup controlfile to trace. Please help.
