标题：在线mv方式迁移数据文件导致数据库无法正常启动

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

有客户在数据库没有关闭的情况下,直接操作系统层面mv方式把数据文件从一个分区迁移到另外一个分区,再创建ln -s(软连接)的方式实现数据文件不修改路径的方式数据文件迁移,结果数据库重启之后,库无法正常启动,报ORA-01172 ORA-01151错误

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
