Tablespace (APPS_TS_MEDIA ) is growing

step 1:  select * from
(select SEGMENT_NAME, sum(bytes)
from dba_segments where TABLESPACE_NAME='APPS_TS_MEDIA'
group by segment_name order by 2 desc)
where rownum <= 10;

Step 2:  

Use the following query to find out currently set value for PCTVERSION:

select PCTVERSION from dba_lobs where TABLE_NAME = 'FND_LOBS' and COLUMN_NAME='FILE_DATA'; 

PCTVERSION

----------

        10

Step 3: 

PCTVERSION can be changed using the following SQL (it can be run anytime in a running system):

ALTER TABLE FND_LOBS MODIFY LOB (FILE_DATA) ( PCTVERSION 0 );
