I have move all tables from one tablespace to a newly created tablespace. I have also move and rebuilt all indexes from this tablespace to the new tablespace. When I query the anount of space each object is taking up there is a total of 800M. But the tablespace is taking up 17000M. What is responsible for taking up this extra space?

What size did you give to the new datafile when you created it?  If you turned on autoextend, what is the NEXT value you specified?

Please post the query you are using to determine the spaced used by the objects.

I gave it 2048M when I created it with 50M auto extend.

Space used by objects:

SELECT distinct owner, segment_name, segment_type, a.bytes/1048576
FROM dba_extents a, dba_data_files b
WHERE a.file_id = b.file_id
AND b.file_name = '/u02/oradata/CORELITE/datafile/FLIP01.DBF'
order by 3;

I'm pretty sure the MOVE commands keeps all allocated space for the original table but compresses them into a single extent.

So if the table have 100G allocated to it in 50 extents when you moved it, it now allocated 1-100G extent.

Did you specify new storage parameters when you moved it?

There is an example here:

If rows were deleted how do you get the space back after moving it?
slightwv (䄆 Netminder) Commented:
The move was to get it out of the tablespace and reset the High Water Mark so you could resize the original datafile.

It looks like you need to specify new storage parameters to reset the initial extent on a MOVE.

That said, you can try the new 10g shrink/resize from the link above.
