2025年的Oracle 8.0.5数据库恢复

发表于 2025 年 7 月 10 日由惜分飞

在10多年前恢复过几个Oracle 8.0版本的库
记录8.0.5数据库恢复过程
 ORACLE 8.0.5 ORA-01207故障恢复
 记录一次AIX 4.3.0+ORACLE 8.0.5恢复过程
没有想到在2025年的7月份还有朋友咨询8.0.5的库恢复case.心中一阵小激动,回想到当年的很多过往(在邮储的机房里面恢复从保险柜中拿出来的小带库恢复8.0.5的库,问领导bbed资料答复网上都有的失落,朋友给我发一个dul的激动,拿到oracle vpn畅游在oracle的internal资料库的爽快等等),感觉这个8.0.5的库不单是一个case,更是一种情怀,大环境的去o,也是一种大浪逝去留下的无奈,不过总的来说也算为Oracle已经奉献了最好的青春和精力,也挺自豪的.这次的库恢复本身不难,简单的总结下:
准备环境
把数据文件发给了我,准备win xp环境的虚拟机并安装8.0.5的库(安装版本要和数据库文件版本一致)

把数据文件,redo等拷贝到虚拟机中,并使用rename file方式重命名文件路径

尝试recover数据库

SVRMGR> recover database;
ORA-00283: ??????????
ORA-01122: ?????29????
ORA-01110: ????29?'C:\805\XFF15'
ORA-01200: 974848?????????2048000??????

报ORA-01200错误,比较明显29号文件本身大小应该是2048000个block,但是现在只有974848个

2025-06-30  11:30     4,194,306,048 XFF14
2022-06-30  09:02     1,996,490,752 XFF15
2022-06-30  09:02     4,194,306,048 XFF16

明显该XFF15文件大小和文件头记录的不匹配,对文件头进行修改(或者修改文件大小)类似处理方法:
bbed处理ORA-01200故障
 记录一次ORA-01200完美恢复
 ORA-01122 ORA-01200故障处理
 ORA-1200/ORA-1207数据库恢复

继续尝试恢复并打开数据库

SVRMGR> recover database;
完成介质的恢复。
SVRMGR> alter database open;
语句已处理。
SVRMGR>

由于29号文件部分丢失,导出数据遭遇ORA-08103错误
模拟普通ORA-08103并解决
 模拟极端ORA-08103并解决
 数据库启动ORA-08103故障恢复
 数据库打开遭遇ORA-08103故障处理
 ORA-01092 ORA-00604 ORA-08103故障处理

对于这种错误,可以按照行的方式使用plsql进行逐行抽取,但是由于涉及的表比较多,比较麻烦,我这里直接使用dul对其进行抽取异常表

然后把导出来的dmp,结合dul恢复出来的异常表数据,整合到一起,完成本次8.0.5的数据库恢复
下次遇到该版本不知道是什么时候,截个图纪念下

oracle 8.1.6因断电无法启动恢复

发表于 2018 年 10 月 17 日由惜分飞

接到一个oralce 8.1.6的数据库恢复请求，由于断电之后，系统无法正常恢复，通过尝试recover datafile报错如下

SQL> select * from v$version;

ORA-00312: online log 2 thread 1: 'D:\ORACLE\ORADATA\ORCL\REDO02.LOG'

这里可以获取到两个信息:1)system文件可能有坏块,导致数据库recover的时候报ORA-600 kcoapl_blkchk错误，2)数据库的redo可能异常了,由于8i数据库默认redo 10m，在业务繁忙时候切换较为频繁，而文件系统的cache导致redo信息比较老,而数据文件需要redo比较新,从而无法正常恢复成功。比较明显对于当前这样的情况只能是屏蔽数据一致性，强制拉库

错误比较明显ORA-600 4194,而且已经告知是由于rollback segment 2异常，通过屏蔽回滚段,open数据库，删除老回滚段,创建新回滚段(8i无undo自动管理)
