    显示指定集群数据库的所有服务
    $ srvctl config service -d orcl
    orcltest PREF: orcl2 orcl1 AVAIL:
    显示节点应用程序的配置—（VIP、GSD、ONS、监听器）
    $ srvctl config nodeapps -n linux1 -a -g -s -l
    VIP exists.: /linux1-vip/192.168.1.200/255.255.255.0/eth0:eth1 GSD exists. ONS daemon exists. Listener exists.
    显示ASM实例的配置
    $ srvctl config asm -n linux1
    +ASM1 /u01/app/oracle/product/10.2.0/db_1
    集群中所有正在运行的实例
    SELECT
    inst_id
    , instance_number inst_no , instance_name inst_name , parallel , status , database_status db_status , active_state state , host_name host
    FROM gv$instance
    ORDER BY inst_id;
    INST_ID INST_NO INST_NAME PAR STATUS DB_STATUS STATE HOST

    2 2 orcl2 YES OPEN ACTIVE NORMAL rac2
    位于磁盘组中的所有数据文件

    启动/停止RAC集群
    确保是以 oracle UNIX 用户登录的。我们将从rac1节点运行所有命令：
    # su– oracle
    $ hostname
    Rac1
    停止Oracle RAC 10g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
