之前整理了2篇Oracle 10gRAC的启动与关闭相关的文章，参考：

Oracle RAC 常用维护工具和命令

一．启动和停止集群

   在Oracle 11gR2 下的RAC，架构发生了变化。CRS的信息也是放在ASM 实例里的，所以要关asm,必须关闭crs, 如果还使用了acfs的话，一关crs那么acfs里的信息也不能访问了，所以一般不重启机器，不轻易关crs, 其他的service可以根据自己的需要去stop/start。

注意：

11g RAC 开启资源相对比较慢(即使命令后面显示的资源都start succeeded,通过crs_stat -t查看都不一定online), 需要耐心并查看log。

    在Oracle 11gR2 里引入了Oracle Restart的特性，其用来管理Cluster Resource。关于Oracle Restart，参考我的Blog：

Oracle 11g 新特性 -- Oracle Restart 说明

1.1 使用crsctl stop has/crsctl stopcrs

用root用户，在Oracle11gR2中停止和启动集群的命令如下：

#crsctl stop has [-f]

#crsctl start has

注意：

    对于crsctl stop has 只有一个可选的参数就是-f，该命令只能停执行该命令服务器上的HAS.而不能停所有节点上的。所以要把RAC 全部停掉，需要在所有节点执行该命令。

下面的2个命令：使用crs 和 使用has 效果是完全一样的：

#crsctl stop crs [-f]

#crsctl start crs

示例：

--停止HAS

[root@rac1 bin]# ./crsctl stophas
