ORA-00600 – Database SOS

标题：记录一次存储异常数据库恢复后遗症ORA-600[kafspa:columnBuffer1]错误处理

先说下前提,这个库以前是由于存储异常,找硬件厂商做了raid重组,然后我进行数据恢复的,恢复出来数据之后,应用厂商通过验证和补数据,然后迁移到另外一台机器做生产用的,这个库一直没有怎么看,最近检查数据库发现ORA-600[kafspa:columnBuffer1]错误,通过删除异常记录的方式解决.

通过上面的alert日志和trace文件以及人工收集统计信息，基本上可以定位是由于数据库自动收集统计信息进程在进行统计信息收集之时，对于”CHF”.”T_XIFENFEI”表进行收集统计信息由于某种错误,从而出现该错误.查询mos，发现此类问题主要是由于varchar2类型存储的数据长度超过了表定义长度.

这里通过exp验证到数据在GETDRUG_FLAG列上有异常，本来定义列长度为2，可是实际数据长度为17，明显不符

通过plsql定位具体错误rowid

第 1 行出现错误:

通过这里基本上可以定位到是该条rowid记录有问题，和业务进行沟通，确定该条记录可以删除(也不能访问，其实不删除也没用)

删除异常记录

SQL> delete from CHF.T_XIFENFEI WHERE ROWID='AAAT8wAAEAAAM29AAX';
已删除 1 行。

提交完成。

收集统计信息

SQL> EXEC DBMS_STATS.gather_table_stats('CHF','T_XIFENFEI',CASCADE=>TRUE)
;
PL/SQL 过程已成功完成。

通过清理异常记录，数据库可以正常收集统计信息，未再报ORA-00600[kafspa:columnBuffer1]错误，故障较完美解决

补充几个现象
1. analyze table “CHF”.”T_XIFENFEI” estimate statistics; 分析表统计信息正常,但是dbms_stats收集报错(因为dbms_stats相当对于每个列进行了扫描,而analyze应该不是)
2. 在报ORA-00600[kafspa:columnBuffer1]的情况下,ctas依旧可以成功,但是普通插入不行(因为ctas相当加油append操作）,因此在有些情况下,需要慎重append(特别是有逻辑坏块的时候)

标题：bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决

在Oracle使用的过程中,经常遭遇一些核心index出现异常，导致数据库无法正常使用,特别是在数据库open的情况下,因为出现这些bootstrap$中的部分index是无法通过设置event38003进行重建,从而导致数据库无法正常使用,最常见异常index 有:I_ICOL1, I_TS1, I_CDEF1, I_CDEF2, I_CDEF3, I_CDEF4, I_PROXY_DATA$, I_IND1, I_TS#, I_UNDO1, I_UNDO2, I_COBJ#, I_USER1, I_USER2, I_CON1, I_CON2, I_FILE1, I_FILE2, I_FILE#_BLOCK#, I_USER#, I_OBJ#, I_PROXY_ROLE_DATA$_1, I_PROXY_ROLE_DATA$_2, I_CCOL1, I_CCOL2, I_TAB1, I_COL1, I_COL2, I_COL3, I_OBJ1, I_OBJ2, I_OBJ3, I_OBJ4, I_OBJ5
重建的index异常报错有:ORA-00701,ORA-01410,ORA-08102,ORA-08103,ORA-01578,ORA-01499,ORA-00600等各类错误
因为处理细节复杂,无法一一描述出来.这里假设Oracle数据库一个非常核心的表OBJ$中的I_OBJ1异常,现在准备重建它,大概步骤如下:
1. 假设异常index信息（I_OBJ1）

SQL> alter index sys.i_obj1 rebuild;
alter index sys.i_obj1 rebuild
*
ERROR at line 1:
ORA-00701: object necessary for warmstarting database cannot be altered

2. 创建获取异常index所属表

SQL>  select table_name from dba_indexes where owner='SYS' AND INDEX_NAME='I_OBJ1';

3. 获取obj$ ddl 语句

  9    BUFFER_POOL DEFAULT FLASH_CACHE DEFAULT CELL_FLASH_CACHE DEFAULT)
 10    TABLESPACE "SYSTEM"
 11  /
Table created.

8.插入数据

insert into obj$img select * from obj$;
insert into bootstrap$img select * from bootstrap$;
commit;

9. 删除bootstrap$img对象名

delete from bootstrap$img where obj# in
 (select obj# from obj$
  where name in ('OBJ$',  'I_OBJ1',  'I_OBJ2', 'I_OBJ3', 'I_OBJ4', 'I_OBJ5',
                 'BOOTSTRAP$'));
commit;

10. 插入新创建对象

insert into bootstrap$img select * from bootstrap$tmpstr;
commit;

11. 关闭数据库

SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

12. bbed修改相关block值

不同版本对应的基表和index结构不一样(本篇blog使用的是12c做试验),但是本方法支持数据库从Oracle 7到Oracle 12c对于bootstrap$中核心index处理.
因为重建bootstrap$中的核心index是一个复杂而且风险非常大的事情,在你无法确定风险或者无法正常完成此类操作之时,如有需要请联系我
