DBV-00100: Specified FILE (XXXX) not accessible


Using the verification tool ‘dbverfNN’ produces the error:

DBV-00100: Specified FILE (XXXX) not accessible

where ‘XXXX’ is the name of the file that ‘dbverf’ was invoked on.

Possible Causes and Remedies

  1. The file does not exist or was incorrectly specified. Check that the specified file exists.
  2. The datafile to be verified must end with ‘.dbf’. Try renaming the file (be careful, the file must be renamed and Oracle informed that it has been renamed).
  3. The file is in use, and is therefore locked and so the utility cannot open it. Shutdown Oracle and try again. (Possibly NT only.)
  4. If the database has been shutdown then it is possible that that Oracle service has the file locked. Try stopping the service ‘OracleService<SID>’. (NT only.)
