方法一:Oracle的死锁非常令人头疼,总结了一些点滴经验作为学习笔记 1.查哪个过程被锁 查V$DB_OBJECT_CACHE视图: SELECT*FROMV$DB_OBJECT_CACHEWHEREOWNER='过程的所属用户'ANDLOCKS!='0'; 2. 查是哪一个SID,通过SID可知道是哪个SESSION. 查V$ACCESS视图:

方法一:Oracle的死锁非常令人头疼,总结了一些点滴经验作为学习笔记


 

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 LOCKS!='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:

KILL -9 刚才查出的SPID

ORAKILL 刚才查出的SID 刚才查出的SPID

方法二:
 

经常在oracle的使用过程中碰到这个问题,所以也总结了一点解决方法:)
1)查找死锁的进程:
sqlplus "/as sysdba"
SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#,l.ORACLE_USERNAME,l.OS_USER_NAME,l.PRO

CESS FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID; 
2)kill掉这个死锁的进程:
alter system kill session ‘sid,serial#’;  (其中sid=l.session_id)
3)如果还不能解决,
select pro.spid from v$session ses,v$process pro where ses.sid=XX and ses.paddr=pro.addr;  
 其中sid用死锁的sid替换。
exit
ps -ef|grep spid
其中spid是这个进程的进程号,kill掉这个Oracle进程。
