硬件故障恢复出文件之后数据库故障处理

客户那边硬件故障(raid损坏磁盘超过了极限,导致raid offline),通过硬件恢复出来数据文件,然后尝试自行恢复,我接手的时候大量数据文件resetlogs scn异常.

重建控制文件报错

WARNING: Default Temporary Tablespace not specified in CREATE DATABASE command
Default Temporary Tablespace will be necessary for a locally managed database in future release
Errors in file /home/oracle/app/diag/rdbms/orcl/orcl/trace/orcl_ora_5949.trc:
ORA-01189: file is from a different RESETLOGS than previous files
ORA-01110: data file 153: '/home/oracle/oracledata/orcl/sysaux02.dbf'
ORA-1503 signalled during: CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS  ARCHIVELOG

通过修改文件头然后重建控制文件,可以通过bbed,或者我的小工具Oracle Recovery Tools
bbed解决ORA-01190
Oracle Recovery Tools 解决ORA-01190 ORA-01248等故障
重建control遗漏数据文件,reseltogs报ORA-1555错误处理
然后继续重建ctl发现以下错误

WARNING: Default Temporary Tablespace not specified in CREATE DATABASE command
Default Temporary Tablespace will be necessary for a locally managed database in future release
Errors in file /home/oracle/app/diag/rdbms/orcl/orcl/trace/orcl_ora_34075.trc:

ORA-1503 signalled during: CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS  NOARCHIVELOG

通过对比发现是由于客户上传恢复文件异常导致

重新上传文件,然后修改文件头,该问题解决,重建ctl成功,提个醒:对于这种硬件恢复之后文件上次到服务器上进行恢复的,一定要确认上传文件和原文件一致,不然做无用功或者恢复效果差很多
尝试open数据库报ORA-600 2662错误

SQL> alter database open resetlogs;
alter database open resetlogs

ERROR at line 1:
ORA-00603: ORACLE server session terminated by fatal error

这个错误比较简单,一般是scn问题，有过大量的处理经验案例:
使用bbed解决ORA-00600[2662]
硬件故障导致ORA-600 2662错误处理
Patch SCN工具快速解决ORA-600 2662问题
解决好该问题之后,数据库open成功,实现了最大限度抢救数据.
