oracle查询锁表解锁语句

一.查询锁定的表

如下语句，都可以查询锁定的表

语句一：

select a.sid,
       a.serial#,
       p.spid,
       c.object_name,
       b.session_id,
       b.oracle_username,
       b.os_user_name
  from v$process p, v$session a, v$locked_object b, all_objects c
 where p.addr = a.paddr
   and a.process = b.process
   and c.object_id = b.object_id
   and c.OBJECT_name = 'TABLE_NAME';

语句二：

SELECT s.sid, s.serial#, o.object_name, s.machine
  FROM gv$locked_object l, dba_objects o, gv$session s
 WHERE l.object_id　 = o.object_id
   AND l.session_id = s.sid
   AND o.object_name = 'TABLE_NAME';

语句三：

SELECT l.session_id sid,
       s.serial#,
       l.locked_mode,
       l.oracle_username,
       l.os_user_name,
       s.machine,
       s.terminal,
       o.object_name,
       s.logon_time
  FROM v$locked_object l, all_objects o, v$session s
 WHERE l.object_id = o.object_id
   AND l.session_id = s.sid
   AND o.object_name = 'TABLE_NAME'
 ORDER BY sid, s.serial#;

语句四：

select a.sid,
       b.serial#,
       c.object_name,
       decode(a.lmode,
              0,
              'None',
              1,
              'Null',
              2,
              'Row-S',
              3,
              'Row-X',
              4,
              'Share',
              5,
              'S/Row-X',
              6,
              'Exclusive',
              'Unknown') LockMode,
       B.MACHINE,
       D.SPID,
       b.PROGRAM
  from v$lock a, v$session b, all_objects c, V$PROCESS D
 where a.sid = b.sid
   and a.type in ('TM', 'TX')
   and c.object_id = a.id1
   and B.PADDR = D.ADDR
   and c.object_name = 'TABLE_NAME';

 

二.kill掉锁住的进程，解锁

--释放SESSION SQL
alter system kill session 'SID,serial#';
