select object_name,machine,s.sid,s.serial#
from v$locked_object l,dba_objects o ,v$session s
where l.object_id = o.object_id and l.session_id=s.sid;
2.查询那个session引起表被锁
复制代码
select b.username,b.sid,b.serial#,logon_time
from v$locked_object a,v$session b
where a.session_id = b.sid order by b.logon_time；
select object_name,machine,s.sid,s.serial#
from v$locked_object l,dba_objects o ,v$session s
where l.object_id = o.object_id and l.session_id=s.sid;
3.解锁表
复制代码
ALTER system kill session '614, 50281';
第二种解锁表的方式
1. 查看被锁的表
复制代码
SELECT p.spid, a.serial#, c.object_name, b.session_id, b.oracle_username,b.os_user_name
FROM v$process p, v$session a, v$locked_object b, all_objects c
WHERE p.addr = a.paddr
AND a.process = b.process
AND c.object_id = b.object_id;
2.批量解锁
复制代码
declare cursor mycur is
select b.sid,b.serial#
from v$locked_object a,v$session b
where a.session_id = b.sid group by b.sid,b.serial#;
begin
for cur in mycur
loop
execute immediate ( 'alter system kill session '''||cur.sid || ','|| cur.SERIAL# ||''' ');
end loop;
end;
