又一例存储cache丢失oracle数据库恢复

Posted on 2021 年 07 月 22 日 by 惜分飞

10.2.0.5 hp unix rac,由于存储掉电导致cache丢失,数据库无法正常启动,客户要求我们介入处理
数据库mount报ORA-00600 kccpb_sanity_check_2错误

该错误是由于控制文件损坏,尝试重建控制文件报ORA-01163,ORA-01517

由于redo大小错误导致该问题,设置正确的redo大小继续重建

标题：硬件故障导致ORA-600 2662错误处理

前几天恢复了一个40多T的CASE:ORA-00600: internal error code, arguments: [16513], [1403] 恢复,又一个近30T的库由于硬件故障,通过其他人一系列恢复之后,无法正常open,让我们提供技术支持:
故障最初原因是由于存储异常
