3、节点执行命令并维护要执行操作之间的协调.一些集群维护操作可能影响HACMP配置拓扑和资源,但通过HACMP系统治理工具C-SPOC,无需停止关键作业即可执行这些任务如添加或删除资源、用户和更改拓扑元素.注意：C-SPOC使用一种新的集群通信守护进程(clcomdES) 在远程节点上执行命令.如果此守护进程没有运行或者无法验证来自发起者节点的请求,将不会执行远程节点上的命令,因此C-SPOC操作将会失败.使用C-SPOC实用工具,在一个节点(发起更改的节点)上执行的命令也会在其他集群节点上执行.C-SPOC最大限度地减少了治理开销,并降低了节点状态不一致的可能性以下我们将利用 C-SPOC功能来
