Oracle control file errors

Don Burleson

 

During database startup, Oracle must be able to read the control file to get the names of the data files, etc.

Because of this important requirement, all Oracle DBA staff should place multiple copies of the controlfile, preferably on separate disk devices.

If Oracle cannot read the control file, you may see this Oracle controlfile error:

         ORA-00204: error in reading (block string, # blocks string) of controlfile

To always have a controlfile backup, use the ALTER DATABASE BACKUP CONTROLFILE TO TRACE command to create a control file recreation script in the location specified by the USER_DUMP_DEST initialization parameter.
