TEMP tbs:
<snip>

if you don't mind a small correction to your script :

SELECT   b.SID,
         b.username,
         b.machine,
         (SELECT VALUE 
            FROM v$parameter 
          WHERE NAME = 'db_block_size') * SUM (a.blocks)  / 1024

used_mb

    FROM v$sort_usage a, v$session b
   WHERE a.session_addr = b.saddr(+)
GROUP BY b.SID, b.username, b.machine
ORDER BY used_mb DESC;

Your version assumes an 8K block size, the above gets the exact block size and moves the multiply outside the 'loop' doing the SUM().

Cheers,
Norman.
