Hot to gain space back in a tablespace after purging

Question

Hi,
We are Oracle Apps shop running 11.5.0.2 and DB on 11.2.02
Some of our tablespaces are about 90% full.
I can always add dataifles to it, but before that, I purged a lot of old WF data (almost 3 M rows).
But my tablespace is still showing me 90 %. It has not gone down.
How do I get the space back?
TIA,
AZ

from dba_extents de, dba_free_space dfs
where de.tablespace_name = 'APPS_TS_TX_IDX'
and de.tablespace_name = dfs.tablespace_name
/You might want to re-think that piece of SQL - if I have 8 extents used and 5 chunks of free space in a tablespace then your join is going to give me 40 rows to aggregate, effectively scaling the used space up by 5 and the free space by 8. A UNION ALL would be a better bet.

If you never mark your questions as answered people will eventually decide that it's not worth trying to answer you because they will never know whether or not their answer has been of any use, or whether you even bothered to read it.
It is also important to mark answers that you thought helpful - again it lets other people know that you appreciate their help, but it also acts as a pointer for other people when they are researching the same question, moreover it means that when you mark a bad or wrong answer as helpful someone may be prompted to tell you (and the rest of the forum) what's so bad or wrong about the answer you found helpful.
