Oracle RAC的关闭及启动，需要严格按照步骤来执行，以下就以一套实际的系统为例，来介绍RAC的关闭及启动过程：
环境说明
| 主机名 | 实例名 | 监听端口 | 字符集 |
| db-node1 | orcl1 | 1521 | ZHS16GBK |
| db-node2 | orcl2 | 1521 | ZHS16GBK |
关闭
顺序：关闭数据库（实例）-> 关闭ASM实例 -> 关闭节点服务
查看状态： $ srvctl status database -d orcl
Instance orcl1 is running on node db-node1 Instance orcl2 is running on node db-node2

关闭数据库：$ srvctl stop database -d orcl
关闭ASM： $ srvctl stop asm -n db-node1
$ srvctl stop asm -n db-node2
关闭各节点服务（listener，gsd，ons，vip）
$ srvctl stop nodeapps -n db-node1
$ srvctl stop nodeapps -n db-node2
启动
启动节点服务 -> 启动ASM实例 -> 启动数据库实例
启动各节点服务
$ srvctl start nodeapps -n db-node1
$ srvctl start nodeapps -n db-node2
启动AMS实例：
$ srvctl start asm -n db-node1
$ srvctl start asm -n db-node2
$ srvctl status asm -n db-node1
$ srvctl status asm -n db-node2
