Oracle Database Discussions

Hi,

oracle version : oracle 8.1.7

os : sun solaris

database size 1000gb

we have deleted millions of rows from many tables but we have't workaround to release the space (like export n import, move tables)

now how can i get the actual size of database.

i used to calcaulte database size by using select sum(bytes)/1024/1024 /1024from dba_data_files;

but in my scenerio i have deleted millions of rows how can find how much data actually consuming the space in database aka present database size.

appreciated valuable inputs.

Thanks
Prakash
