查看Oracle中是否有锁表的sql

复制代码 代码如下:

select 'blocker('||lb.sid||':'||sb.username||')-sql:'|| qb.sql_text blockers,
'waiter ('||lw.sid||':'||sw.username||')-sql:'|| qw.sql_text waiters
from v$lock lb,
v$lock lw,
v$session sb,
v$session sw,
v$sql qb,
v$sql qw
where lb.sid=sb.sid
and lw.sid=sw.sid
and sb.prev_sql_addr=qb.address
and sw.sql_address=qw.address
and lb.id1=lw.id1
and sw.lockwait is not null
and sb.lockwait is null
and lb.block=1 ;

复制代码 代码如下:

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 ;

复制代码 代码如下:

select b.owner,b.object_name,l.session_id,l.locked_mode fromv$locked_object l, dba_objects

复制代码 代码如下:

SELECT sid, serial#, username, osuser FROMv$session;

复制代码 代码如下:

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;

复制代码 代码如下:

alter system kill session 'sid,serial#';
