内容简介：这篇文章主要介绍了数据库ORA-01196故障-归档日志丢失恢复详解，具有一定参考价值，需要的朋友可以了解下。
问题：
由于机房停电，其中一DG备库无法open，启动时报错
启动数据库时报下面的错误
SQL> alter database open; alter database open *
第 1 行出现错误:
ORA-10458: standby database requiresrecovery
ORA-01196: 文件 1 由于介质恢复会话失败而不一致
ORA-01110: 数据文件 1:'+DATA/htdb7/datafile/system.313.884996245'
查看归档日志应用情况，发现一部分日志没应用

解决办法：
需要从其它备库或主库上面把此备库缺失的归档日志手动传输过来，然后再进行open操作
步骤如下：
1. 在另一正常的备库用rman备份缺失的归档日志
[oracle@hotel05 ~]$ rman target / RMAN> copy archivelog'+fra/htdb5/ARCHIVELOG/2017_03_24/thread_1_seq_328759.4592.939510649' to'/home/oracle/arcbak/thread_1_seq_328759.4592.939510649';
启动 backup 于 25-3月 -17
使用通道 ORA_DISK_1
通道 ORA_DISK_1: 正在开始复制归档日志
输入归档日志线程=1 序列=328759 RECID=328754 STAMP=939510652
输出文件名=/home/oracle/arcbak/thread_1_seq_328759.4592.939510649 RECID=328794STAMP=939571923
通道 ORA_DISK_1: 归档日志复制完成, 经过时间: 00:00:03
完成 backup 于 25-3月 -17
......
. 备份完成后，把归档传输到丢失归档的备库
[oracle@hotel05 arcbak]$ scp * hotel07:/home/oracle/arcbak/
3. 然后在此备库上进行恢复操作
-- 编制归档文件目录
[oracle@hotel07 ~]$ rman target /

4. 最后就可以open数据库了

总结：
在由于停电和网络原因，造成主备数据不同步，日志丢失的情况，主要学会使用rman工具把归档文件在fs和asm之间传输。在数据库恢复时会经常用到。
另外，如果数据库开启了闪回功能 ，也可以使用闪回数据库的某个时点进行恢复。可以参考另一篇博文：oracle数据库ORA-01196错误解决办法分享。
