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"
