unable to open database

[karimdba]

Hi everyone,I've got a problem when trying to open my database.I can only mount it.
The error is that the controlfile is older than the datafile and I can't open the database.Here is the error :
ora-01122:database failed verification check
ora-01110:data file 1:'f:\base\sys1carf.ora'
ora-01207:file is more recent than controlfile -old controlfile

i've tried every solution i've found(try a recover until cancel ...) and it didn't work.
Can anyone give me a way to restore my database?
Thanks by advance.

First my apologies is these suggestions are things you have already tried.


First thing to look at - are you mirroring your control files? If so, are they all the same date/time? If not, then you can copy the most recent one to the other location(s) (with the database down) and try to restart.

Another thing you could try is the CREATE CONTROLFILE command - to just create a brand new controlfile.

ORA-01207 file is more recent than controlfile - old controlfile

Cause: The control file change sequence number in the datafile is greater than the number in the control file. This implies that the wrong control file is being used. Note that repeatedly causing this error can make it stop happening without correcting the real problem. Every attempt to open the database will advance the control file change sequence number until it is great enough.

Action: Use the current control file or do BACKUP CONTROLFILE RECOVERY to make the control file current. Be sure to follow all restrictions on doing a BACKUP CONTROLFILE RECOVERY.

BACKUP CONTROLFILE RECOVERY is referring to using a backup controlfile to recover the database (assuming you have a backup of the control file).
