rac四个节点 如果把归档放在本地目录，是否其他节点能否访问到归档

归档位置的设计也有两种方案：

（1）各节点生成的归档放到共享存储上，这样自然可以确保每个节点都能够访问到，比如将归档存放到ORACLE的ASM，或者是第三方提供的集群文件系统中。 对于这种方法，一些集群的配置比较麻烦，而且也增加了ASM的维护，出现问题也不好处理。

（2）各节点除在本地生成归档文件外，另外向其它节点或者说执行备份的节点发送归档日志，以确保执行备份的那台节点能够访问到所有的归档文件。在这种方法中，因为ORACLE 的重做日志发送机制非常灵活，在10g版本中可以同时向10个目标地写入归档(11g增加到了30个)，所以利用这种特性，将各节点生成的归档发送到执行备份的节点中，来实现该节点能够访问所需的归档文件。
