1.下面的语句用来查询哪些对象被锁: 代码如下 select object_name,machine,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; 2.下面的语句用来杀死一个进程: 代码如下 alter

   1.下面的语句用来查询哪些对象被锁:

代码如下  

select object_name,machine,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;

  2.下面的语句用来杀死一个进程:

代码如下  

alter system kill session '24,111';

  (其中24,111分别是上面查询出的sid,serial#)

  【注】以上两步,可以通过Oracle的管理控制台来执行。

  3.如果利用上面的命令杀死一个进程后,进程状态被置为"killed",,但是锁定的资源很长时间没有被释放,那么可以在os一级再杀死相应的进程(线程),首先执行下面的语句获得进程(线程)号:

代码如下  

select spid, osuser, s.program
from v$session s,v$process p
where s.paddr=p.addr and s.sid=24 (24是上面的sid)

  4.在OS上杀死这个进程(线程):

  1)在unix上,用root身份执行命令:

  #kill -9 12345(即第3步查询出的spid)

  2)在windows(unix也适用)用orakill杀死线程,orakill是oracle提供的一个可执行命令,语法为:

  orakill sid thread

  其中:

  sid:表示要杀死的进程属于的实例名

  thread:是要杀掉的线程号,即第3步查询出的spid。

  例:c:>orakill orcl 12345
