oracle数据库报错ora-600 [ktbdchk1: bad dscn] and ora-8103 corrupted block解决
时间:2022-06-29 09:33:45 编辑:袖梨 来源:一聚教程网
前两天一同事的数据库alert log不停的在刷出ora-600 [ktbdchk1: bad dscn]错误,影响的是一张table上的insert语句, 前不久该数据库存储出现过故障,从已知BUG中没有找到相似案例,环境11.2.0.4 2nodes RAC,未配置Data Guard, 这里只是简单的记录一下问题的处理过程。

From MOS
Format: ORA-600 [ktbdchk1: bad dscn] [a] [b] [c] [d] [e]
SUGGESTIONS:
Check all machine hardware for possible errors.
Run dbverify (dbv) utility on the datafiles in question.
Run a full export on the database and check for corruption.
If possible rebuild any corrupted objects with export/drop/import

因为不能远程连接,确认问题要过中间两个人,所以没有记录一些具体信息,且数据库还一直OPEN,只是影响了部分(前几天数据库存储坏过)。
这里有个疑问的是为什么表上无lob字段, trace 中提示有lob type? 是oracle写异常? 如果你知道请mail告诉我。
分析方法:
1, 查找TRACE 中的OBJ# ,确认对象就是insert 所使用的表
2, 确认了该表上无索引,且无LOB 字段
3, flush buffer cache
4, CTAS 失败 报ora-8103
5, ANALYZE TABLE [TABLENAME] STRUCTURE CASCADE online; 失败 报ora-8103
所以最后按照解决 表 ora-8103的方法就可以避免这个ora-600, 这个案例确认该表不重要可以丢失部分数据。
1,找到corrupted block, 可以使用8103 trace 进一步跟踪也可以先解决ora-600 trace中的数据块先, dbv(rman) verify该数据文件再查询v$database_block_corruption
2,如果有unique + not null索引 ,那样当然可以使用MOS 上提供的脚本,根据rowid跳过异常的行恢复
3,如果没有索引,可以根据dba+obj# 使用DBMS_ROWID.ROWID_CREATE 生成大概的rowid(不知行数),也可以使用rowid跳过
4,如果了解bbed, 也可以尝试修改ktbbhcsc 里的SCN为略小于当前的SCN
5, 利用抽取类工具
6, 如果该表数据目前不重要,新建表,rename互换,后期手动追加数据
