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

SQL> alter database open resetlogs;
alter database open resetlogs
*
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
*
ERROR at line 1:

Oracle Recovery Tools 解决ORA-01190 ORA-01248等故障

今天有一个客户数据库恢复请求,通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)脚本分析发现resetlog信息异常
20210106182747


导致数据库恢复报ORA-01190 ORA-01110错

alter database open

通过Oracle Recovery Tools工具进行修复resetlog 信息

再次尝试open数据库报ORA-1248错

通过多次resetlogs规避类似ORA-01248: file N was created in the future of incomplete recovery错误

数据库现状
控制文件
recover_xifenfei0
控制文件中数据文件信息
recover_xifenfei1
数据文件头信息
recover_xifenfei2
redo信息
recover_xifenfei3
根据当前数据库恢复检查脚本(Oracle Database Recovery Check)收集的信息,数据库的是非归档状态,而且redo已经覆盖,数据库datafile 5 无法直接online.遇到这样情况,可以使用bbed修改文件头scn实现online(使用bbed让rac中的sysaux数据文件online),也可以通过使用_allow_resetlogs_corruption等隐含参数实现online.本恢复案例中有180个数据文件,160个offline,然后open数据库,所以大量数据文件无法正常online,bbed工作量太大.在恢复过程中不幸遇到ORA-01248

数据库resetlogs出现ORA-01248错误
