This should be in the Oracle sub-forum

Hhere's a query I use, if you're logged in as system then you run the same query against dba_extents:
PHP Code:
 select segment_name, round(sum(bytes)/1024/1024,2) Mb , sum(decode(extent_id, 0, bytes, 0)) initial_ex,
       sum(decode(extent_id, 1, bytes, 0)) next_ex , max(extent_id)+1 extents , sum(bytes) ttlsize 
 from user_extents 
 Where segment_type='TABLE'
group by segment_name
order by 5 desc
