Answer 1

Temp used:
SELECT A.tablespace_name tablespace, D.mb_total,
SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_used,
D.mb_total - SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_free
FROM v$sort_segment A,
SELECT B.name, C.block_size, SUM (C.bytes) / 1024 / 1024 mb_total
FROM v$tablespace B, v$tempfile C
WHERE B.ts#= C.ts#
GROUP BY B.name, C.block_size
) D
WHERE A.tablespace_name = D.name
GROUP by A.tablespace_name, D.mb_total;
Temp usage per session:
SELECT S.sid || ‘,’ || S.serial# sid_serial, S.username, S.osuser, P.spid, S.module,
P.program, SUM (T.blocks) * TBS.block_size / 1024 / 1024 mb_used, T.tablespace,
COUNT(*) statements
FROM v$sort_usage T, v$session S, dba_tablespaces TBS, v$process P
WHERE T.session_addr = S.saddr
AND S.paddr = P.addr
AND T.tablespace = TBS.tablespace_name
GROUP BY S.sid, S.serial#, S.username, S.osuser, P.spid, S.module,
P.program, TBS.block_size, T.tablespace
ORDER BY sid_serial;
