今天网友遇到ora-600错误，这里把这个ora-600错误的解决方法详细记录一下。
最初报错信息如下：
ora-600-图1
ora-600-图2
图3
这里我们可以看到报错控制文件版本不一致，要求网友备份控制文件，并且修改参数文件使用高版本控制文件启动数据库。
启动后报错ora-600如下图所示：
图4
要求查看alert日志，信息如下：
图5
要求查看跟踪文件内容，如下：
可以看到这里报了一个error：kccpb_sanity_check_2的错误。查看eygle的文档可知这个错误的意思如下：
ORA-00600 kccpb_sanity_check_2错误，这个错误是因为控制文件不一致导致的。出现这个错误时，数据库将无法Mount挂载，影响数据库服务。这个错误，多数是因为存储故障，丢失了数据写。
Oracle对此错误的解释是：
[kccpb_sanity_check_2] indicates that the seq# of the last read block is higher than the seq# of the control file header block. This is indication of the lost write of the header block during commit of the previous cf transaction.
其解释是：kccpb_sanity_check_2 表示最后读取的控制文件块其 seq# 控制序列号大于控制文件头块的 seq# ,这是不应该出现的情况。这说明在最后执行提交的控制文件事务（CF Transaction）中，对于头块的写入丢失了。
这个错误如果只是存在于控制文件上，可以通过重建控制文件来解决，毫无疑问，这是最为简单的处理方式。如果有备份，也可以从备份中恢复完好的控制文件，但是重建通常是很快捷的方式。
