記一起由Oracle心跳引起的生產庫故障
作者：雪竹頻道
節點之間連接心跳網絡的網線有問題，導致心跳網絡異常，RAC節點之間不能正常通信，腦裂，ORACLE的服務被中止。RAC集群為了保證一致性和完整性，在心跳網絡異常的情況下，會發生腦裂，ORACLE實例會被強制中止。
一、問題描述
環境描述：
節點 | sid | db_name | software_version | 備注 |
172.16.2.22 | hdls1 | HDLS | 11.2.0.4 | rac節點 |
172.16.2.23 | hdls2 | HDLS | 11.2.0.4 | rac 節點 |
事件原因：
兩個節點的心跳網絡異常，導致RAC腦裂，中斷了節點運行的oracle實列進程，數據庫服務宕掉。
二、過程
1、 時間：16：45報障處理
檢查發現兩臺oracle實例進程中止，無法正常連接。
2、時間：17：25恢復23節點
恢復23節點，保證業務作業可正常進行，排查22節點故障。等待作業完成處理。
- 重啟22節點后，23節點的數據服務恢復正常
reboot -f
- 檢查23節點的數據庫服務狀態
crs_stat -t
3、對節點22進行分析

通過上面的日志可以看出，兩個節點之間心跳網絡通信異常，不能各自獲取對端節點的信息，導致oracle實例進程中止。
系統日志
通過上述日志可以看出eno3心跳網口狀態一直在DOWN和UP之間循環，狀態不穩定。
4、時間：22：30出現23單節點監聽掛起
由于心跳網絡故障，兩節點無法正常通信，22：30，23節點實例中斷，23：38，23節點數據庫服務恢復。
5、時間：00：30作業結束后，更換心跳6類線
- 等業務作業運行結束后，對心跳線進行更換，更換心跳6類線。
- 22節點嘗試啟動數據庫服務，成功。
- srvctl start instance -d HDLS -i hdls1
6、時間：00：30 數據庫恢復正常

三、小結
- 節點之間連接心跳網絡的網線有問題，導致心跳網絡異常，RAC節點之間不能正常通信，腦裂，ORACLE的服務被中止。RAC集群為了保證一致性和完整性，在心跳網絡異常的情況下，會發生腦裂，ORACLE實例會被強制中止。
- 更換心跳6類線后，數據庫恢復正常。
