Oracle查看锁表，引起锁表的SQL语句，KILL锁表进程

--查看数据库引起锁表的SQL语句

SELECT A.USERNAME,A.MACHINE,A.PROGRAM,A.SID,A.SERIAL#,A.STATUS,C.PIECE,C.SQL_TEXT 
  FROM V$SESSION A, V$SQLTEXT C
 WHERE A.SID IN (SELECT DISTINCT T2.SID FROM V$LOCKED_OBJECT T1, V$SESSION T2 WHERE T1.SESSION_ID = T2.SID)
   AND A.SQL_ADDRESS = C.ADDRESS(+)
 ORDER BY C.PIECE;

--查看锁表

select sess.sid,sess.serial#, lo.oracle_username,lo.os_user_name, ao.object_name,lo.locked_mode
  from v$locked_object lo,dba_objects ao,v$session sess
 where ao.object_id=lo.object_id and lo.session_id=sess.sid;

--杀掉锁表进程
--分别为SID和SERIAL#号

alter system kill session 'XXX,XXX';
