Unfortunately, your space will remain the same because delete
doesn't deallocate the free space allocated to the table whether
you shut the database down or not. The ways to deallocate space
would be to 
a) Rebuild the table in another tablespace with significantly reduced
   storage parameters (8i and newer)
b) Truncate the table, which is almost equivalent to dropping and recreating
   the table. The good news is that you don't have to re-issue grants or
   re-create indexes.

Hi
I deleted millions of rows from diffrent tables and I have not seen any 
impact on database size.What I have to do to get that free space?
Is it necessary to shutdown the database?
Thx
-Seema
