oid$=:12,spare1=:13, spare2=:14 where owner#=:1 and name=:2 and namespace=:3 and 
remoteowner is null and linkname is null and subname is null

这里可以的出来由于obj$中的dataobj#为87422,而i_obj4中的dataobj#为87420,因此两者不一致。
另外通过相关trace发现,在创建表操作中会调用update obj$的一个递归操作,而该操作会更新dataobj#,但是由于该值在表和index中不匹配,因此出现ORA-08102导致创建表不成功

使用bbed 修复ORA-8102

ORA-00604: 递归 SQL 级别 1 出现错误
ORA-00942: 表或视图不存在

通过这里可以知道数据库在启动的过程中由于无法访问access$表从而出现ORA-00942错误,又是由于该sql是数据库内部调用因为出现ORA-00604错误.
出现该错误的原因是由于:BUG:12733463 – ORA-704, ORA-604 AND ORA-942 ON TABLE ACCESS$ DURING STARTUP
官方提供方法

1. Shutdown (abort) the instance and clean up any OS structures used by the instance. 
    Eg: Ensure there is no shared memory, semaphores etc.. left lying around

2. Retry the startup.

3. If the error persists try and recover the database or recover from a backup.

该异常文件使用dul/odu均无法正常识别.证明文件头确实已经损坏

dbv 检测

dbv检测结果无坏块,但是v$datafile_header和alert日志中报坏块,初步判断是由于该文件是bigfile,dbv未检测到文件头坏块,实际该该数据文件头损坏，其他block正常.所幸的是该库有9月份的rman备份(中间归档丢失),因此使用rman还原出来9月份的数据文件,然后使用dd拷贝两个 block(block 0和block 1)到异常文件.

尝试恢复数据库

SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done


SQL> recover database using backup controlfile;
ORA-00283: recovery session canceled due to errors
ORA-19909: datafile 4 belongs to an orphan incarnation

使用bbed修改相关文件头,然后继续恢复
具体见：bbed解决ORA-01190类似方法处理

出现ORA-600[2662]错误,因为scn相差比较小，重启数据库机器,出现ORA-600[4194]错误

重建控制文件后继续恢复

设置undo_management=MANUAL然后继续恢复

[oracle@db tmp]$ sqlplus / as sysdba

这次的恢复也证明Oracle 12C确实有着越来越多的用户在使用.
