查看Oracle的死锁

1、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

 
2、查看那个用户那个进程造成死锁

select b.owner,b.object_name,l.session_id,l.locked_mode 
from v$locked_object l, dba_objects b where b.object_id=l.object_id;

3、查看造成死锁的原因

 select sql_text from v$sql where hash_value in   
 (select sql_hash_value from v$session where sid in  (select session_id from v$locked_object));  

  

4、查看连接的进程 

SELECT sid, serial#, username, osuser 
FROM v$session where username='sys'; 

5、杀掉进程 

alter   system     kill   session   'sid,serial#';
