找出 alter system kill session ‘sid,serial#’ kill 掉的数据库会话对应spid进程

当我们使用alter system kill session ‘sid,serial#’ 在数据库中kill掉某个会话的时候,如果你观察仔细会发现v$session.paddr发生了改变,从而是的不能直接通过关联v$process.add找出spid,然后进行其他操作.本文提供三种方法找该种情况下spid的方法.
查看Oracle数据库版本

SQL> select * from v$version;

BANNER
-----------------------------------------------------------------------
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
PL/SQL Release 11.2.0.3.0 - Production
CORE    11.2.0.3.0      Production
TNS for Linux: Version 11.2.0.3.0 - Production
NLSRTL Version 11.2.0.3.0 - Production

会话1

SQL> select sid, SERIAL#,paddr from v$session where 
  2  sid=(select sid from v$mystat where rownum=1);

       SID    SERIAL# PADDR
---------- ---------- --------
       133         53 35FE16F4

会话2

SQL> select sid, SERIAL#,paddr from v$session where 
  2  sid=(select sid from v$mystat where rownum=1);

       SID    SERIAL# PADDR
---------- ---------- --------
       143         21 35FE2D3C

会话3

SQL> alter system kill session '133,53';

System altered.

SQL> alter system kill session '143,21';

System altered.

SQL> select sid, SERIAL#,paddr,status from v$session where sid in(133,143);

       SID    SERIAL# PADDR    STATUS
---------- ---------- -------- ----------------
       133         53 3547A3F4 KILLED
       143         21 3547A3F4 KILLED

证明alter system kill session后,v$session中的paddr发生了改变,这个时候如果需要找出原来的spid,不能使用v$session.paddr和v$process.addr关联获得

找出kill掉的spid方法一

SQL> select spid, program from v$process 
  2      where program!= 'PSEUDO' 
  3      and addr not in (select paddr from v$session)
  4      and addr not in (select paddr from v$bgprocess)
  5      and addr not in (select paddr from v$shared_server);

SPID                                             PROGRAM
------------------------------------------------ ------------------------------

14256                                            oracle@xifenfei (L000)
15300                                            oracle@xifenfei (TNS V1-V3)
14179                                            oracle@xifenfei (D000)
15318                                            oracle@xifenfei (TNS V1-V3)
14252                                            oracle@xifenfei (N000)


SQL> !ps -ef|grep 15300|grep -v grep
oracle   15300 14052  0 03:22 ?        00:00:00 oracleora11g (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))

SQL> !ps -ef|grep 15318|grep -v grep
oracle   15318 15315  0 03:22 ?        00:00:00 oracleora11g (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
