近日，公司搭建的ORACLE 11G RAC 出现故障，整个故障的排错思路大概持续了一周左右，最终确定了问题原因，现在简介下ORACLE 11G RAC的环境：
jbdb1 IBM P740 AIX 6100-08-02-1316
jbdb2 IBM P740 AIX 6100-08-02-1316
Oracle 11G 11.2.0.3 grid and database
当日，软件人员说无法连接数据库，我就很纳闷，于是就登录到系统，通过查看群集发现整个RAC有异常，正当我查看群集状态时候出现：
hostname:/home/grid$crs_stat -t CRS-0184: Cannot communicate with the CRS daemon.
通过登录两个节点发现同样的问题，ORACLE Cluster 无法启动crs群集管理，crs无法启动更谈不上什么服务了，数据库无法启动，服务中断。
现在是没有什么办法只有先恢复应用再说，于是手动执行crsctl start cluster -all 结果还是不能启动crs对应的服务，错误依旧。最后进行crs的检测
hostname:/home/grid$crsctl check crs CRS-4638: Oracle High Availability Services is online CRS-4535: Cannot communicate with Cluster Ready Services CRS-4529: Cluster Synchronization Services is online CRS-4534: Cannot communicate with Event Manager
通过上面可以看到CRS无法通信，并且事件管理也无法通信连接。并且查询crs resource运行状态
节点1：

通过上面信息可知节点1的ora.asm offline，ora.crsd offline 同时也会伴随asm后台无法启动
节点2ora.crsd INTERMEDIATE,在整个排查过程中，尝试过重启两节点，但是重启完毕后，crs的状态还是一样的，数据库不可使用。被迫无奈判断问题，于是大胆关闭一个节点，同时喜剧的时刻发生了，节点2上是应用资源都正常，所有群集资源漂移至节点2上，包括底层的ASM还有数据库instance状态可用。

没有办法后来查看crsd.log日志，在节点1上看到如下日志：

通过上面的测试发现有数据包丢失虽然心跳地址任然通信，会不会RAC通过测定数据包丢失而判断心跳失效，从而发生类似“脑裂”的问题，结合crsd.log中gipchaLowerProcessNode: no valid interfaces found to node for 2789821594 ms”，通过上面信息判断问题出现在RAC心跳上，于是想利用独立交换机接入节点1、2的心跳网卡，通过这个操作，奇迹发送了，节点1、2的crs尽然启动了，群集资源也没有异常，可以查看crsd.log日志如下：
