VNKTUMMALA, I also think the same. There is tablespace named DMS_BLOB that has 9 datafiles and all of them are nearly fully packed up. These are datafiles of permanent tablespace.

Just for evidence to Dave:

SQL> select file_id,tablespace_name,file_name,bytes/1024/1024/1024 from dba_data_files
2 where file_id not in (select file_id from dba_free_space)
3 /

FILE_ID TABLESPACE_NAME FILE_NAME BYTES/1024/1024/1024
