oracle死锁

解决方案如下：
1.查哪个过程被锁: 
查V$DB_OBJECT_CACHE视图: 
SELECT * FROM V$DB_OBJECT_CACHE WHERE OWNER='过程的所属用户' AND CLOCKS!='0'; 
2. 查是哪一个SID,通过SID可知道是哪个SESSION: 
查V$ACCESS视图: 
SELECT * FROM V$ACCESS WHERE OWNER='过程的所属用户' AND NAME='刚才查到的过程名'; 
3. 查出SID和SERIAL#： 
查V$SESSION视图: 
SELECT SID,SERIAL#,PADDR FROM V$SESSION WHERE SID='刚才查到的SID'; 
查V$PROCESS视图: 
SELECT SPID FROM V$PROCESS WHERE ADDR='刚才查到的PADDR'; 
4. 杀进程： 
(1)先杀ORACLE进程: 
ALTER SYSTEM KILL SESSION '查出的SID,查出的SERIAL#'; 
(2)再杀操作系统进程: （linux)
KILL -9 刚才查出的SPID或ORAKILL 刚才查出的SID 刚才查出的SPID。


SELECT /*+ rule */ lpad(' ',decode(l.xidusn ,0,3,0))||l.oracle_username User_name,
o.owner,o.object_name,o.object_type,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
ORDER BY o.object_id,xidusn DESC
/

drop user src cascade;
//查询数据库当前连接数
select sid,serial# from v$session where username='SRC';
alter system kill session '182,35496'; 

//查询是否死锁
select username,lockwait,status,machine,program from v$session where sid in(select session_id from v$locked_object);
//查询死锁进程
select s.username,I.object_id,I.session_id,s.serial#,I.oracle_username,I.os_user_name,I.process from v$locked_object I,V$session s where I.session_id = s.sid;
kill
alter system kill session '182,35496';  sid(session_id),serial#
alter system kill session '182,35496#'; 
或杀进程：
select pro.spid from v$session ses,v$process pro where ses.sid='1188' and ses.paddr = pro.addr;
select pro.spid from v$session ses,v$process pro where ses.sid='707' and ses.paddr = pro.addr;
