RAC配置（启停库）
关库顺序 ：先关闭数据库 然后关闭节点资源
[root@rac1 ~]# srvctl stop database -d 数据库名
[root@rac1 ~]# srvctl stop instance -d 数据库名 -i 实例1
[root@rac1 ~]# srvctl stop instance -d 数据库名 -i 实例2
[root@rac1 ~]# srvctl stop nodeapps -n 节点1
[root@rac1 ~]# srvctl start nodeapps -n 节点2
启库顺序相反
[root@rac1 ~]# srvctl start nodeapps -n 节点1
[root@rac1 ~]# srvctl start nodeapps -n 节点2
[root@rac1 ~]# srvctl start instance -d 数据库名 -i 实例1
[root@rac1 ~]# srvctl start instance -d 数据库名 -i 实例2
[root@rac1 ~]# srvctl start database -d 数据库名
[root@rac1 ~]# srvctl stop database -d prod root用户关库命令
[root@rac1 ~]# srvctl start database -d prod root用户启库命令
[root@rac1 ~]# srvctl stop instance -d prod -i prod1 关闭实例
[root@rac1 ~]# crsctl stop crs 关闭crs资源
[root@rac1 ~]# crsctl check crs 查看crs资源的状态
[root@rac1 ~]# crs_stat -t
[root@rac1 ~]# srvctl stop nodeapps -n rac1 关闭节点应用 rac1
[root@rac1 ~]# more /etc/inittab
