半夜朋友打来求救电话,说xx医院his系统因为存储异常导致system坏块无法正常启动,因为是win平台无法使用bbed,无法修复system 坏块,请求技术支持
dbv检查system文件报坏块
对应具体地址为:file 1 block 39041和66738
判断控制文件异常
通过数据库恢复检查脚本(Oracle Database Recovery Check)脚本检测数据库发现控制文件明显异常(checkpoint scn
尝试恢复数据库
因此对该库进行了不完全恢复,然后尝试resetlogs打开数据库,数据库报ORA-600 2662错误

ORA-600 2662 该错误解决思路很明显,推进scn,数据库报ORA-01578

使用event跳过坏块,启动数据库成功

查询坏块对象
因为这些对象均不是核心对象,直接进行truncate然后插入老数据
后续还有大量错误修复
ORA-12012: error on auto execute of job 1 ORA-08102: index key not found, obj# 239, file 1, block 1674 (2) ORA-00600: 内部错误代码, 参数: [kcbz_check_objd_typ], [0], [0], [1], [], [], [], [] ORA-00600: internal error code, arguments: [6749], [3], [12606796], [173], [], [], [], [] ORA-00600: 内部错误代码, 参数: [13013], [52898], [52895], [38288618], [44], [38288618], [17], [] ORA-00600: 内部错误代码, 参数: [13013], [5001], [52895], [38286476], [5], [38286476], [17], []
再次说明,很多时候数据库恢复不要看成多神秘,就是几个参数搞定,更加不要神化有坏块就bbed修复,当然非常极端,使用N中工具,N种尝试的也存在.做好备份重于一切
