启动与关闭Oracle rac数据库集群

和学操作系统一样，安装完RAC集群后，第一件事就是就是要学习如何启动和关闭，启动和关闭rac一般使用三种方式:sqlplus,srvctl以及

[oracle@rac2 ~]$ srvctl start nodeapps -n rac1
[oracle@rac2 ~]$ srvctl start nodeapps -n rac2
[oracle@rac2 ~]$ srvctl start asm -n rac1
[oracle@rac2 ~]$ srvctl start asm -n rac2
[oracle@rac2 ~]$ srvctl start instance -d racdb -i racdb1 -o mount
[oracle@rac2 ~]$ srvctl start instance -d racdb -i racdb2 -o open
