oracle查询锁表和解锁

1.数据库表被锁后------解锁

第一步

select t2.username, t2.sid, serial#, t2.logon_time
from v$locke{d}_{o}bjectt1,v$session t2
where t1.SESSION_ID = t2.SID;

select t2.username, t2.sid, serial#, t2.logon_timefrom v$locked_object t1, v$session t2where t1.SESSION_ID = t2.SID;

第二步

alter system kill session ‘91,64898’;

2.查锁语句

select sess.sid,
sess.serial#,
lo.oracle_username,
lo.os_user_name,
ao.object_name,
lo.locked_mode ,
machine,
program
from v$locke{d}_{o}bjectlo,db{a}_{o}bjectsao,v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

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