oracle记录一次存储异常数据库恢复后遗症ORA-600[kafspa:columnBuffer1]错误处理
时间：2022-06-29 09:47:27 编辑：袖梨 来源：一聚教程网
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
SQL> set serveroutput on
SQL> DECLARE
2 TYPE RowIDTab IS TABLE OF ROWID INDEX BY BINARY_INTEGER;
3 CURSOR c1 IS select /*+index(t PK_T_XIFENFEI_BAK_NEW)*/ rowid from CHF.T_XIFENFEI t;
4 r RowIDTab;
5 rows NATURAL := 20000;
6 bad_rows number := 0 ;
7 errors number;
8 error_code number;
9 myrowid rowid;
10 BEGIN
11 OPEN c1;
12 LOOP
13 FETCH c1 BULK COLLECT INTO r LIMIT rows;
14 EXIT WHEN r.count=0;
15 BEGIN
16 FORALL i IN r.FIRST..r.LAST SAVE EXCEPTIONS
17 insert into CHF.T_XIFENFEI_new
18 select /*+ ROWID(A) */ *
19 from CHF.T_XIFENFEI A where rowid = r(i);
20 EXCEPTION
21 when OTHERS then
22 BEGIN
23 errors := SQL%BULK_EXCEPTIONS.COUNT;
24 FOR err1 IN 1..errors LOOP
25 error_code := SQL%BULK_EXCEPTIONS(err1).ERROR_CODE;
26 myrowid := r(SQL%BULK_EXCEPTIONS(err1).ERROR_INDEX);
27 bad_rows := bad_rows + 1;
28 insert into system.had_rows values('CHF.T_XIFENFEI',myrowid, error_code);
29 END LOOP;
30 END;
31 END;
32 commit;
33 END LOOP;
34 commit;
35 CLOSE c1;
36 dbms_output.put_line('Total Bad Rows: '||bad_rows);
37 END;
38 /
Total Bad Rows: 1
PL/SQL 过程已成功完成。
SQL> SELECT row_id FROM system.had_rows ;
ROW_ID
------------------
AAAT8wAAEAAAM29AAX
SQL> select * from CHF.T_XIFENFEI WHERE ROWID='AAAT8wAAEAAAM29AAX';
select * from CHF.T_XIFENFEI WHERE ROWID='AAAT8wAAEAAAM29AAX'

第 1 行出现错误:
ORA-00600: 内部错误代码, 参数: [kafspa:columnBuffer1], [2883], [1], [], [], [],
[], [], [], [], [], []
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。
SQL> commit;
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)
