Hi,
in 8.1.7 I have a tempfile that does not exist physically :

SQL> select file_name, tablespace_name, status from dba_data_files where tablespace_name='TEMP';

FILE_NAME
--------------------------------------------------------------------------------
TABLESPACE_NAME                STATUS
------------------------------ ---------
C:\ORACLE\ORA81\DATABASE\MISSING00004
TEMP                           AVAILABLE

C:\ORACLE\ORADATA\TEST\TEMPORARY_02B.DBF
TEMP                           AVAILABLE


SQL> host dir C:\ORACLE\ORA81\DATABASE\MISSING00004
 Volume in drive C has no label.
 Volume Serial Number is A01E-34E8

 Directory of C:\ORACLE\ORA81\DATABASE

File Not Found

And I want to drop it :

SQL> alter database drop TEMPFILE 'C:\ORACLE\ORA81\DATABASE\MISSING00004';
alter database drop TEMPFILE 'C:\ORACLE\ORA81\DATABASE\MISSING00004'
*
ERROR at line 1:
ORA-01900: LOGFILE keyword expected

How can I drop it ?
Thank you.
