停止 Oracle RAC10g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 IP、GSD、TNS 监听器和 ONS）。
$ export ORACLE_SID=orcl1
$ emctl stop dbconsole
$ srvctl stop instance -d orcl -i orcl1
$ srvctl stop asm -n rac1
$ srvctl stop nodeapps –n rac1
启动 Oracle RAC 10g 环境
第一步是启动节点应用程序（虚拟 IP、GSD、TNS 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=orcl1
$ srvctl start nodeapps -n rac1
$ srvctl start asm -n rac1
$ srvctl start instance -d orcl -i orcl1
$ 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
