Oracle RAC的關閉及啟動，需要嚴格按照步驟來執行，以下就以一套實際的系統為例，來介紹RAC的關閉及啟動過程：
環境說明
| 主機名 | 實例名 | 監聽端口 | 字符集 |
| db-node1 | orcl1 | 1521 | ZHS16GBK |
| db-node2 | orcl2 | 1521 | ZHS16GBK |
關閉
順序：關閉數據庫（實例）-> 關閉ASM實例 -> 關閉節點服務
查看狀態： $ srvctl status database -d orcl
Instance orcl1 is running on node db-node1 Instance orcl2 is running on node db-node2

關閉數據庫：$ srvctl stop database -d orcl
關閉ASM： $ srvctl stop asm -n db-node1
$ srvctl stop asm -n db-node2
關閉各節點服務（listener，gsd，ons，vip）
$ srvctl stop nodeapps -n db-node1
$ srvctl stop nodeapps -n db-node2
啟動
啟動節點服務 -> 啟動ASM實例 -> 啟動數據庫實例
啟動各節點服務
$ srvctl start nodeapps -n db-node1
$ srvctl start nodeapps -n db-node2
啟動AMS實例：
$ srvctl start asm -n db-node1
$ srvctl start asm -n db-node2
$ srvctl status asm -n db-node1
$ srvctl status asm -n db-node2
