通过这里的分析,我们可以得出file 1 block 122的内容未提交,可能是导致错误ORA-00600[4000],尝试这手工提交该事务

根据这个错误提示ktbdchk–>bad dscn,猜测ktbdchk是header scn中的ktbdchk,查找1020770e发现是itl comomit scn,通过bbed查看

通过这里可以知道ORA-00600[ktbdchk1: bad dscn]是因为itl comomit scn远大于datafile header scn,从而oracle认为datafile header scn是错误的,从而提示ktbdchk1: bad dscn.尝试bbed修改itl comomit scn
