手工杀掉oracle进程和手工释放共享内存是非常危险的，不到万不得已，千万不要使用，容易造成数据不一致。这个方法是作为没有办法

我的dataguard因为ora-600错误导致备机hang住，使其无法登陆Oracle数据库

参考：

现象
[root@skate01 ~]# su - oracle
[oracle@skate01 ~]$ sqlplus "/as sysdba"

SQL*Plus: Release 11.2.0.2.0 Production on Tue Feb 21 00:26:35 2012

ERROR:
ORA-01075: you are currently logged on

[oracle@skate01 ~]$

为了快速登录oracle，，好迅速启动oracle，这里提供一种超暴力的方法

1.使用Linux的kill命令杀死所有与oracle有关的进程
$ ps -ef |grep $ORACLE_SID|grep -v grep|awk '{print $2}' | xargs kill -9

2.使用Linux的ipcs和ipcsrm命令释放oracle占用的共享内存
$ ipcs -m | grep oracle | awk '{print $2}' | xargs ipcrm shm

操作步骤：
[root@skate01 ~]# su - oracle
[oracle@skate01 ~]$ sqlplus "/as sysdba"
SQL*Plus: Release 11.2.0.2.0 Production on Tue Feb 21 00:35:11 2012

ERROR:
ORA-01075: you are currently logged on
