一、问题描述
环境描述：
节点 | sid | db_name | software_version | 备注 |
172.16.2.22 | hdls1 | HDLS | 11.2.0.4 | rac节点 |
172.16.2.23 | hdls2 | HDLS | 11.2.0.4 | rac 节点 |
事件原因：
两个节点的心跳网络异常，导致RAC脑裂，中断了节点运行的oracle实列进程，数据库服务宕掉。
二、过程
1、 时间：16：45报障处理
检查发现两台oracle实例进程中止，无法正常连接。
2、时间：17：25恢复23节点
恢复23节点，保证业务作业可正常进行，排查22节点故障。等待作业完成处理。
- 重启22节点后，23节点的数据服务恢复正常
reboot -f
- 检查23节点的数据库服务状态
crs_stat -t
3、对节点22进行分析

通过上面的日志可以看出，两个节点之间心跳网络通信异常，不能各自获取对端节点的信息，导致oracle实例进程中止。
系统日志
通过上述日志可以看出eno3心跳网口状态一直在DOWN和UP之间循环，状态不稳定。
4、时间：22：30出现23单节点监听挂起
由于心跳网络故障，两节点无法正常通信，22：30，23节点实例中断，23：38，23节点数据库服务恢复。
5、时间：00：30作业结束后，更换心跳6类线
- 等业务作业运行结束后，对心跳线进行更换，更换心跳6类线。
- 22节点尝试启动数据库服务，成功。
- srvctl start instance -d HDLS -i hdls1

三、小结
- 节点之间连接心跳网络的网线有问题，导致心跳网络异常，RAC节点之间不能正常通信，脑裂，ORACLE的服务被中止。RAC集群为了保证一致性和完整性，在心跳网络异常的情况下，会发生脑裂，ORACLE实例会被强制中止。
- 更换心跳6类线后，数据库恢复正常。
