Problems with dropping datafile in tablespace

After I did the following:

alter database datafile 'c:\oracle\oradata\db\tools\T1.dbf' offline drop;

select file_name, tablespace_name from dba_data_files;

The datafile that I dropped was still shown as part of the tablespace. Why is that? Received on Thu May 01 2003 - 05:17:52 CDT
