啟動和停止集群
以下操作需用root用戶執行

注在運行crsctl stop cluster命令之後如果 Oracle Clusterware 管理的資源中有任何一個還在運行則整個命令失敗使用 f 選項無條件地停止所有資源並停止 Oracle Clusterware 系統
另請注意可通過指定 all 選項在集群中所有服務器上停止 Oracle Clusterware 系統如下所示在rac和rac上停止oracle clusterware系統
[root@rac ~]# /u/app//grid/bin/crsctl stop cluster –all
在本地服務器上啟動oralce clusterware系統
[root@rac ~]# /u/app//grid/bin/crsctl start cluster
注可通過指定 all 選項在集群中所有服務器上啟動 Oracle Clusterware 系統
[root@rac ~]# /u/app//grid/bin/crsctl start cluster –all
還可以通過列出服務器（各服務器之間以空格分隔）在集群中一個或多個指定的服務器上啟動 Oracle Clusterware 系統
[root@rac ~]# /u/app//grid/bin/crsctl start cluster n rac rac
使用 SRVCTL 啟動/停止所有實例:
[oracle@rac ~]#srvctl stop database d racdb
[oracle@rac ~]#srvctl start database d racdb
安裝的後置任務
．官方建議的兩個安裝後置任務
() 備份 rootsh 腳本
官方建議在完成安裝後要備份rootsh腳本文件如果在Oracle Home目錄中又安裝其它的產品安裝時OUI會升級已存在的rootsh文件如果需要rootsh內的原始信息就可以在備份中找到
cd $ORACLE_HOME;cp rootsh rootshbak
()重新編譯無效對象
運行 utlrpsql 腳本立即重新編譯所有無效的 PL/SQL 程序包而不是在首次訪問它們時再重新編譯這是個可選步驟但建議您選擇該步驟
[oracle@racnode ~]$ sqlplus / as sysdba
SQL> @?/rdbms/admin/utlrpsql
在 RAC 環境中啟用存檔日志
()以 oracle 用戶身份登錄到一個節點（即 racnode）通過在當前實例中將 cluster_database 設置為 FALSE 來禁用集群實例參數
[oracle@rac ~]$ sqlplus / as sysdba
SQL> alter system set cluster_database=false scope=spfile sid=racdb;
System altered
()以 oracle 用戶身份關閉所有 訪問集群化數據庫的實例
[oracle@rac ~]$ srvctl stop database d racdb
()使用本地實例掛載數據庫
[oracle@rac ~]$ sqlplus / as sysdba

()啟用存檔功能
SQL> alter database archivelog;

()通過在當前實例中將實例參數 cluster_database 修改為 TRUE重新啟用對集群的支持
SQL> alter system set cluster_database=true scope=spfile sid=racdb;

()關閉本地實例
SQL> shutdown immediate

()以 oracle 帳戶身份使用 srvctl 命令重啟所有實例
