Cannot open database
HI
OS :HP-UX PA RISC 11.23 / 64 bit
Oracle version : 10.2.0.1
I'm facing the unknown problem with my database. My old controlfie was missing the the datafile UNDO2.dbf and I have a bad backupset which cannot use it for restore. Then I recreated a new controlfile by using the current datafiles but UNDO2. It seemed to be OK until I open the database ( I'v created case on Oracle Metalink, they're working with that . I'm very thankful to all of your advices and hope that there are some experts here in this forum can help me out .
