对oracle锁的查找及清除

查找死锁记录

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;

清除死锁记录,从上面的sid,serial替换下面6,6891

--  sid,serial
alter system kill session '6,6891';
