oracle查看死锁的信息和查看死锁的语句

检查产生死锁的机器：

select username,lockwait,status,machine,program from v$session where sid in
(select session_id from v$locked_object)

检查产生死锁的语句：

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))

查看死锁的进程：

SELECT s.username,l.OBJECT_ID,l.SESSION_ID,s.SERIAL#,
l.ORACLE_USERNAME,l.OS_USER_NAME,l.PROCESS
FROM V$LOCKED_OBJECT l,V$SESSION S WHERE l.SESSION_ID=S.SID;

然后alter system kill session 'sid,serial#';

select pro.spid from v$session ses,v$process pro where ses.sid=XX and ses.paddr=pro.addr;

找到spid，spid就是oracle对应在操作系统的进程号

kill -9 spid

这样就可以解除死锁。
