How Do You Find Who And What SQL Is Using Temp Segments?

For 8.1.7 to 9.2:

SELECT a.username, a.sid, a.serial#, a.osuser, b.tablespace, b.blocks, c.sql_text
FROM v$session a, v$sort_usage b, v$sqlarea c
WHERE a.saddr = b.session_addr
AND c.address= a.sql_address
AND c.hash_value = a.sql_hash_value
ORDER BY b.tablespace, b.blocks;

For 10.1 and above:

SELECT a.username, a.sid, a.serial#, a.osuser, b.tablespace, b.blocks, c.sql_text
FROM v$session a, v$tempseg_usage b, v$sqlarea c
WHERE a.saddr = b.session_addr
AND c.address= a.sql_address
AND c.hash_value = a.sql_hash_value
ORDER BY b.tablespace, b.blocks;
