Oracle 宕机后文件损坏resetlogs后处理

Oracle数据库意外宕机，归档开了，但是归档文件损坏，redo损坏，在强行拉起来之后UNDO报错，设置_corrupted_rollback_segments 跳过不一致的ＵＮＤＯ，重建UNDO表空间，接着报错：SMON encountered 100 out of maximum 100 non-fatal internal errors. 然后数据库自动宕机，报错处理如下：

果断报错

/SQL> analyze table SMON_SCN_TIME validate structure;

要么禁用smon_scn_time刷新：

alter system set events '12500 trace name context forever, level 10';

副作用就是会导致flashback会报错；

ORA-00600: internal error code, arguments: [kewrose_1], [600]由这个错误产生与mmon进程有关，非关键进程，可以杀掉重启，

MOS:ORA-600 [6002] "Index block check" (Doc ID 47449.1)

DESCRIPTION:

Oracle was trying to insert a key and key data into a b*tree index.

In order to do this, it had to first find the correct leaf block to do the insert.

Once the correct leaf block is retrieved, Oracle validates the block

by checking the data size and number of columns in the key.

If there is a mismatch then ORA-600 [6002] is reported.

ARGUMENTS:

Arg [a] Number of bytes in keydata

Arg [b] Number of bytes in the index layer of the leaf header

Arg [c] Number of columns in index search key structure

Arg [d] Number of columns in the index layer fo the leaf header

FUNCTIONALITY:

Kernel Data layer Index

索引问题，找到对应索引，重建，再验证表结构：ANALYZE TABLE xxxxx VALIDATE STRUCTURE CASCADE;

5 ora-00600 [25027] [7] [a] [b]

arg[a] Tablespace Number表空间号

arg[b] 十进制的相对数据块号Relative Data Block Address (RDBA)

表或者索引有问题，重建对应的表或者索引；
