注在运行crsctl stop cluster命令之后如果 Oracle Clusterware 管理的资源中有任何一个还在运行则整个命令失败使用 f 选项无条件地停止所有资源并停止 Oracle Clusterware 系统
另请注意可通过指定 all 选项在集群中所有服务器上停止 Oracle Clusterware 系统如下所示在rac和rac上停止oracle clusterware系统
[root@rac ~]# /u/app//grid/bin/crsctl stop cluster –all
在本地服务器上启动oralce clusterware系统
[root@rac ~]# /u/app//grid/bin/crsctl start cluster
注可通过指定 all 选项在集群中所有服务器上启动 Oracle Clusterware 系统
[root@rac ~]# /u/app//grid/bin/crsctl start cluster –all
还可以通过列出服务器（各服务器之间以空格分隔）在集群中一个或多个指定的服务器上启动 Oracle Clusterware 系统
[root@rac ~]# /u/app//grid/bin/crsctl start cluster n rac rac
使用 SRVCTL 启动/停止所有实例:
[oracle@rac ~]#srvctl stop database d racdb
[oracle@rac ~]#srvctl start database d racdb
安装的后置任务
．官方建议的两个安装后置任务
() 备份 rootsh 脚本
官方建议在完成安装后要备份rootsh脚本文件如果在Oracle Home目录中又安装其它的产品安装时OUI会升级已存在的rootsh文件如果需要rootsh内的原始信息就可以在备份中找到
cd $ORACLE_HOME;cp rootsh rootshbak
()重新编译无效对象
运行 utlrpsql 脚本立即重新编译所有无效的 PL/SQL 程序包而不是在首次访问它们时再重新编译这是个可选步骤但建议您选择该步骤
[oracle@racnode ~]$ sqlplus / as sysdba
SQL> @?/rdbms/admin/utlrpsql
在 RAC 环境中启用存档日志
()以 oracle 用户身份登录到一个节点（即 racnode）通过在当前实例中将 cluster_database 设置为 FALSE 来禁用集群实例参数
[oracle@rac ~]$ sqlplus / as sysdba
SQL> alter system set cluster_database=false scope=spfile sid=racdb;
System altered
()以 oracle 用户身份关闭所有 访问集群化数据库的实例
[oracle@rac ~]$ srvctl stop database d racdb
()使用本地实例挂载数据库
[oracle@rac ~]$ sqlplus / as sysdba

()启用存档功能
SQL> alter database archivelog;

()通过在当前实例中将实例参数 cluster_database 修改为 TRUE重新启用对集群的支持
SQL> alter system set cluster_database=true scope=spfile sid=racdb;

()关闭本地实例
SQL> shutdown immediate

()以 oracle 帐户身份使用 srvctl 命令重启所有实例
