You have gone about a totally wrong way of dropping the datafile. To drop a datafile from a
tablespace, u have to export the tablespace by taking a series of user exports in that tablespace,
dropping the tablespace, deleting the datafile at the OS level, recreating the tablespace with the
proper datafiles and importing back the contents of the tablespace.

Dear gurus !

I have an "offline dropped" datafile at my database. The file was physically deleted at the OS level after "offline drop". Before dropping the file , all the objects that had extents allocated in that file (from dba_extents) were dropped. Now , V$datafile shows this file as of size=0 and status = 'RECOVER' which is fine.
BUT , file$ show this file as of size 8GB, which is the file size as it used to be before being dropped.
Moreover , fet$ shows 8GB as free extents residing at this file . And , after all , tables get created in that file , i.e. dba_extents show extents with FILE_ID of that file !
When a select statement tries to access a table with extents residing in that file , i get an error message , off course.

So , the question is , how do i make the file's extents disappear from fet$ ?
Thanks a lot.

Andrey.
