RAC启动与停止的先后顺序小结
停止RAC：
emctl stop dbconsole
srvctl stop instance -d rac -i rac1
srvctl stop instance -d rac -i rac2
srvctl stop asm -n rac1
srvctl stop asm -n rac2
srvctl stop nodeapps -n rac1
srvctl stop nodeapps -n rac2
启动RAC：
和上面的步骤正好相反即
srvctl start nodeapps -n rac1
srvctl start nodeapps -n rac2
srvctl start asm -n rac1
srvctl start asm -n rac2
srvctl start instance -d rac -i rac2
srvctl start instance -d rac -i rac1
emctl start dbconsole
