Hamid, .dbf is prefectly valid on all machines, as far as I know.
You can rename it - look at the ALTER DATABASE RENAME FILE 'filename' to 'newfilename' clause to rename the data file. You will need to take the tablespace offline to do this. Hope this helps Tom Mercadante Oracle Certified Professional -----Original Message----- Sent: Tuesday, March 26, 2002 11:39 AM To: Multiple recipients of list ORACLE-L I have added a datafile to a the temp tablespace with the name of .dbf only is ithis a valid name?, is there any way to rename it without shutdown the database,if yes HOW?
