查看Oracle中是否有锁表的sql

不要怪女人现实,女人之所以现实,只因经历过爱情的伤生活的磨砺。只有懂得女人为何如此现实的男人,才能够给予女人一份期待中的现实生活。
1、查看是否有锁表的sql
 
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 ;

2、查看被锁的表
 
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 ;

3、查看那个用户那个进程造成死锁,锁的级别
 
select b.owner,b.object_name,l.session_id,l.locked_mode fromv$locked_object l, dba_objects

4、查看连接的进程
 
SELECT sid, serial#, username, osuser FROMv$session;

5、查看是哪个session引起的
 
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;

6、杀掉进程
 
alter system kill session 'sid,serial#';

sid是第5步查询出的sid和serid

到此这篇关于查看Oracle中是否有锁表的sql就介绍到这了。浪费时间可惜;生而不学可惜;学而无成更可惜。更多相关查看Oracle中是否有锁表的sql内容请查看相关栏目,小编编辑不易,再次感谢大家的支持!
