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

Posted 2020-12-27 liang545621

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.
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
