Oracle中查询锁表的sql:

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;

解锁sql：

alter system kill session 'sid,serial#'
例如： alter system kill session'159,9614';
