客户自行恢复到这一步,后面无法处理,接手之后进行恢复，其实后面比较简单了，就是修改下数据库scn,数据库就可以open起来,然后处理异常的undo和对象即可,可以参考以前类似文章:

此类故障是由于在线拷贝数据文件,可能有不少最新写入的数据都有数据文件和redo不一致的风险,引起这里的ORA-600 3020最好不要通过allow N corruption的方式跳过,因为可能导致大量数据文件坏块,这样就不光丢失了redo数据,可能数据文件中好的block中的很多数据也丢失.对于这种情况,我们为了减少客户的数据丢失,选择了最少数据丢失的方法:通过bbed修改文件头,然后直接recover 数据文件,open库
