处理方法一、
--查看锁表进程sql语句1
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;
处理方法二、
--查看锁表进程sql语句2:
select * from v$session t1,v$locked_object t2 where t1.sid = t2.SESSION_ID;
处理方法三、
select * from dba_ddl_locks;
使用sid信息查看视图V$SESSION,获取sid,serial#信息
select * from v$session where sid=?
--杀掉锁表进程:
--如有记录则表示有lock,记录下sid和serial# ,将记录的ID替換下面的sid,serial#,即可解除LOCK
alter system kill session 'sid,serial#';
