oracle数据库的一次异常起停处理。

在重启数据库的时候，忘记把一个应用关停了，想起来的时候，就ctrl+c,把数据库shutdown immediate 给强制停下了，把该应用再停止，然后shutdown immdiate，这时候数据报错了。

oracle@NMSSERVER1:~> sqlplus '/as sysdba'

处理的措施：

1.查看共享内存资源
 ipcs -pmb

oracle@NMSSERVER1:~> ipcs -pm;

------ Shared Memory Creator/Last-op PIDs --------
shmid owner cpid lpid
3145744 oracle 14924 32669
3178513 oracle 14924 32669
3211282 oracle 14924 32669
3244051 oracle 14924 32669
3276820 oracle 14924 32669
3309589 oracle 14924 32669
3342358 oracle 14924 32669
3375127 oracle 14924 32669
3407896 oracle 14924 32669
3440665 oracle 14924 32733

oracle资源在占用，所以必须进行资源释放，执行如下操作：

oracle@NMSSERVER1:~> ipcrm -m 3145744

（这里必须一个一个的停，不能一次停 多个）
