出现这种情况是由于redo和数据文件块不一致导致无法正常应用日志,人工对于异常的block进行处理,数据库open成功,然后遭遇undo回滚段异常,对其进行规避,数据库open并且稳定运行

ERROR: alter diskgroup datac1 mount force

故障原因是由于asm disk 32还已经损坏在换盘过程中(数据没有reblance完成),又损坏了asm disk 39,而这两份磁盘中有数据互为镜像,因此磁盘组无法正常mount起来.

检查cell节点celldisk和griddisk情况，确认底层磁盘损坏

对于这种情况,因为normal冗余的两份数据都有部分丢失,无法直接恢复数据,通过底层磁盘级别恢复(参考以前一次的Oracle exadata故障恢复:Oracle Exadata坏盘导致磁盘组无法mount恢复),然后比较顺利恢复数据,实现业务数据0丢失

SQL> alter datac1 mount;

Diskgroup altered.

SQL> alter diskgroup datac1 check all;

Diskgroup altered.

多套库顺利open成功

在实际恢复过程中由于客户进行了各种尝试,直接新镜像盘然后插入新盘,强制拉磁盘组drop异常disk操作等,导致第一现场发生一些破坏,增加了恢复难道,但是最终通过各种方法弥补,实现了预期的恢复效果(业务数据0丢失)

硬件故障恢复出文件之后数据库故障处理

标题：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;

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.

接手现场之后,关闭数据库,使用操作系统层面反删除工具进行扫描恢复,发现其中一个文件(另外一个文件os层面无法恢复)

通过工具检测恢复出来的数据文件,损坏的几个block是文件头部不涉及业务数据,运气不错

另外一个数据文件,从os层面无法恢复,对于这种情况,只能基于底层的block层面进行恢复(恢复没有覆盖的block)

参考类似恢复案例:
win文件系统损坏oracle恢复
Oracle 数据文件大小为0kb或者文件丢失恢复
分享运气超级好的一次drop tablespace 数据恢复
恢复出来的两个数据文件,结合该编辑的其他数据文件通过dul工具恢复其中数据,最大程度抢救客户数据,减少损失.
