最近接触过几个ORA-600 16703的恢复case,报错日志类似为：

查看客户的日志,发现客户的库被人使用bbed按照网上的思路进行过恢复（使用block替换的方式尝试open库）,结果报出来ORA-00600: internal error code, arguments: [16703], [1403], [4]之类的错误

其实ORA-600 16703 1403 N的错误,表示数据库在检索tab$表的时候,N为发现异常的obj#的值,这里的报错表示数据库在启动过程中无法检索到tab$中的tab$对象,应该是恢复过程中缺少该记录导致,解决问题的思路就是把该记录回写到tab$表中即可
