TEMP Usuage

TEMP Space Used

select tablespace_name, bytes_used/1024/1024, bytes_free/1024/1024 from v$temp_space_header;

USERS Using the tablespace

select b.tablespace, (b.blocks*p.value)/1024/1024 , a.sid, a.username from sys.v_$session a, sys.v_$sort_usage b, sys.v_$parameter p
where p.name=b.session_addr;

To get which user is using temp tablespace

select username,tablespace,extents from v$sort_usage;

TEMP Usuage per session

SELECT   S.sid || ',' || S.serial# sid_serial, S.username, S.osuser, P.spid, S.module,
         S.program, SUM (T.blocks) * TBS.block_size / 1024 / 1024 mb_used, T.tablespace,

GROUP BY S.sid, S.serial#, S.username, S.osuser, P.spid, S.module,
         S.program, TBS.block_size, T.tablespace
ORDER BY sid_serial;

Free and Used Space in Temp Tablespace :

SELECT   A.tablespace_name tablespace, D.mb_total,
         SUM (A.used_blocks * D.block_size) / 1024 / 1024 mb_used,

         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;

By statement --

SELECT   S.sid || ',' || S.serial# sid_serial, S.username,
