启动/停止RAC集群
确保是以 oracle UNIX 用户登录的我们将从rac节点运行所有命令
# su – oracle
$ hostname

停止 Oracle RAC g 环境
第一步是停止 Oracle 实例当此实例（和相关服务）关闭后关闭 ASM 实例最后关闭节点应用程序（虚拟IPGSDTNS 监听器和 ONS）
$ export ORACLE_SID=orcl
$ emctl stop dbconsole
$ srvctl stop instance d orcl i orcl
$ srvctl stop asm n rac
$ srvctl stop nodeapps –n rac
启动 Oracle RAC g 环境
第一步是启动节点应用程序（虚拟 IPGSDTNS 监听器和 ONS）当成功启动节点应用程序后启动 ASM 实例最后启动 Oracle 实例（和相关服务）以及企业管理器数据库控制台
$ export ORACLE_SID=orcl
$ srvctl start nodeapps n rac
$ srvctl start asm n rac
$ srvctl start instance d orcl i orcl
$ emctl start dbconsole
使用 SRVCTL 启动/停止所有实例
启动/停止所有实例及其启用的服务我只是觉得有意思就把此步骤作为关闭所有实例的一种方法加进来了！
$ srvctl start database d orcl
$ srvctl stop database d orcl
