I’d needed to stop archive log mode for some reason.

When I tried to change the mode message told me to some file have been missing.

Alter database noarchivelog;

ORA-01111: name for data file 5 is unknown - rename to correct file

ORA-01110: data file 5: 'C:\APP\JAC484\PRODUCT\11.2.0\DBHOME_1\DATABASE\MISSING00005'

SQL> select FILE#,ERROR from v$recover_file where FILE#=5;


---------- ------------------------------------------------


SQL> select file_id ,file_name from dba_data_files where file_id in (select FILE
    # from v$recover_file where ERROR like 'FILE MISSING' and FILE# = 5);







I’d like to recover or delete above MISSING00005 file.

However, there isn’t any physical file.

Does anyone know how to operate?

I've already delete archivelog all; from RMAN.

Il looks like you (or someone else) deleted the file n°5 BEFORE you were putting DB in noarchivelog. You have to restore this file from a previous backup and recover it to the time you stopped the DB for your operation.

  • Sorry, I didn’t backup this file. I can’t recover by this way. Commented Jun 5, 2017 at 7:11
  • Ouch ! Try follow this Commented Jun 6, 2017 at 17:45
  • And maybe restore an older backup on another machine, extract via datapump the missing data, but if the missing file is member of a multifile tablespace, I don't think you would be able to restore. Commented Jun 6, 2017 at 17:50
  • I didn't do your way.However I have been to able to change 'archivelog' mode to `noarchivelog' mode as I wanted. Commented Jul 10, 2017 at 7:58
  • Could you please describe what you've done ? For passing by people's enlightment. Commented Jul 26, 2017 at 13:01
