Arun ,
Bingo , will Check for the Same using the Following SQL script :-
select b.sid,
substr(a.segment_name,1,25) OBJ_NAME,
a.segment_type OBJ_TYPE,
b.p1,
b.p2 BLOCKID,
b.p3 BLOCKS,
b.event
from dba_extents a,
v$session_wait b
where b.p2 between a.block_id AND (a.block_id+a.blocks)
and a.file_id = b.p1
and b.p1=12
and b.p1text='file#'
and b.event like 'db file scattered%';
NOTE - 12 is the File Number of The Datafile of the respective Tablespace
Any Points , Advice on the same ?
