Which session or query use temporary tablespace and undo tablespace

1) TEMP

SELECT   b.TABLESPACE
       , b.segfile#
       , b.segblk#
       , ROUND (  (  ( b.blocks * p.VALUE ) / 1024 / 1024 ), 2 ) size_mb
       , a.SID
       , a.serial#
       , a.username
       , a.osuser
       , a.program
       , a.status
    FROM v$session a
       , v$sort_usage b
       , v$process c
       , v$parameter p
   WHERE p.NAME = 'db_block_size'
     AND a.saddr = b.session_addr
     AND a.paddr = c.addr
ORDER BY b.TABLESPACE
       , b.segfile#
       , b.segblk#
       , b.blocks;

2) UNDO

SELECT a.name,b.status
FROM   v$rollname a,v$rollstat b
WHERE  a.usn = b.usn
AND    a.name IN (
 SELECT segment_name
 FROM dba_segments
 WHERE tablespace_name = 'UNDOTBS2'
);


SELECT TO_CHAR(s.sid)||','||TO_CHAR(s.serial#) sid_serial,
NVL(s.username, 'None') orauser,
s.program,
r.name undoseg,
t.used_ublk * TO_NUMBER(x.value)/1024||'K' "Undo"
FROM sys.v_$rollname r,
sys.v_$session s,
sys.v_$transaction t,
sys.v_$parameter x
WHERE s.taddr = t.addr
AND r.usn = t.xidusn(+)
AND x.name = 'db_block_size'
