raid强制上线后数据库无法启动故障处理

Posted on 2021 年 04 月 20 日 by 惜分飞

由于raid掉盘过多,强制raid上线,然后启动数据库报以下错误

错误提示比较明显IO error,结合客户强行上线raid的操作,比较明显是由于底层io问题导致该错误,直接对此文件dbv检查

通过对io error的文件进行处理,最终损坏三个block,最大限度抢救数据.使用被恢复出来的文件,尝试open库遭遇以下错误

标题：记录一次oracle现场故障处理经过

近期到现场进行了一个数据库恢复,我在恢复之前该库先由于硬件进行恢复,然后由其他人对其进行了一系列数据库恢复,但是未恢复成功,客户希望我们到现场进行处理(因为网络原因无法远程).接手库之后,处理第一个问题,是客户在进行现场备份的时候(把linux数据拷贝到win的过程中)发现有几个文件拷贝异常,这个错误很可能是由于当初的硬件故障修复之后留下的后遗症(由于io设备错误,无法运行此项请求),通过工具进行拷贝,恢复出来

初步判断是由于对方之前恢复导致部分文件resetlogs scn异常,通过bbed进行判断确认

   ub2 kscnwrp                              @120      0x0000

通过bbed修改相关值,然后重建控制文件成功,尝试resetlogs库，报ORA-01248错误

ERROR at line 1:
ORA-01248: file 234 was created in the future of incomplete recovery
ORA-01110: data file 234: '/oradata1/xifenfeidata5.DBF'

关于ORA-01248的错误解释

01248, 00000, "file %s was created in the future of incomplete recovery"
// *Cause:  Attempting to do a RESETLOGS open with a file entry in the
//          control file that was originally created after the UNTIL time 
//          of the incomplete recovery.
//          Allowing such an entry may hide the version of the file that 
//          is needed at this time.  The file number may be in use for 
//          a different file which would be lost if the RESETLOGS was allowed.
// *Action: If more recovery is desired then apply redo until the creation
//          time of the file is reached. If the file is not wanted and the
//          same file number is not in use at the stop time of the recovery,
//          then the file can be taken offline with the FOR DROP option.
//          Otherwise a different control file is needed to allow the RESETLOGS.
//          Another backup can be restored and recovered, or a control file can
//          be created via CREATE CONTROLFILE.

大概的意思是文件的创建时间大于文件当前的scn,通过查询确实如此

通过对部分scn进行修改（比如减小创建时间的scn)，然后尝试resetlogs库

SQL> alter database open resetlogs;
alter database open resetlogs

标题：Oracle Recovery Tools恢复—ORA-00704 ORA-01555故障

由于虚拟化环境使用了精简模式(预分配),后面出现分布式存储空间不足,导致虚拟化环境中的数据库服务器异常,通过一系列操作恢复好系统,发现数据库无法open,请求我们给予解决
通过我们的Oracle Database Recovery Check脚本分析,分析文件的checkpoint scn 有部分3月2日,还有一些是2月28日,是严重不一致,而且对应的归档也丢失

基于这样的情况,试试看强制打开库

第 1 行出现错误:
ORA-01092: ORACLE instance terminated. Disconnection forced

ORA-00704: bootstrap process failure
ORA-00604: error occurred at recursive SQL level 1

进程 ID: 7928

在数据库open的过程中,报ORA-01555错误,这类问题比较明显以前写过类似文章:
在数据库open过程中常遇到ORA-01555汇总
 数据库open过程遭遇ORA-1555对应sql语句补充
 使用_allow_resetlogs_corruption导致ORA-00704/ORA-01555故障
这次尝试使用自己开发的小程序:Oracle Recovery Tools进行恢复

然后直接尝试打开数据库成功

SQL> alter database open;
alter database open
*
第 1 行出现错误:
ORA-01113: ?? 1 ??????
ORA-01110: ???? 1: 'D:\BAIDUNETDISKDOWNLOAD\DATA\XFF\SYSTEM01.DBF'


SQL> recover database;
完成介质恢复。
SQL> alter database open;

数据库已更改。

这次证明,对于数据库open过程汇总报ORA-00704 ORA-01555故障,可以通过Oracle Recovery Tools工具一键式open库。
后续安排数据导出,对于个别导出报错的表利用dul进行处理,完成本次恢复任务
