Transportable tablespace procedure in oracle 9i

Question

Hi all,
We are using oracle 9.2.0.7 version in our production.In that one tablespace is having 160GB but objects size is 60Gb,am unable to get back the remaining space.So we are planning for either creating new tablespace and moving all the objects to that and dropping earlier one or transportable tablespace(not sure whether it is possible)
So please suggest me the better approch. help me out to transport a tablespace procedure
Thanks a lot

Answer 1

exp/imp is the other option.
Or you can use this query find out the object (table/index) on high water mark and just move them.
select a.tablespace_name
       ,a.file_name
       ,(b.maximum+c.blocks-1)*d.db_block_size highwater
from   dba_data_files a
       ,(select file_id,max(block_id) maximum
         from dba_extents
         group by file_id) b
       ,dba_extents c
       ,(select value db_block_size
         from v$parameter
         where name='db_block_size') d
where a.file_id  = b.file_id
and   c.file_id  = b.file_id
and   c.block_id = b.maximum
order by a.tablespace_name,a.file_name
/
