语法：orakill Service_Name SPID

==================================

先查看session  得出SID

再 select spid, osuser, s.program
from v$session s,v$process p
where s.paddr=p.addr and s.sid=17 得出 SPID

例如
orakill dbcenter 3320

C:\>orakill dbcenter 3320

Kill of thread id 3320 in instance dbcenter successfully signalled.

v$access查被锁对象,SID
v$session通过SID查进程SPID
