  • RMAN-06023: no backup or copy of datafile 1 found to restore

    在ORACLE 10g数据库还原过程遭遇RMAN-06023: no backup or copy of datafile x found to restore,具体情况如下所示

    在RMAN里面使用restore database validate验证备份时也报RMAN-06023错误

    clip_image002

    RMAN> list backup of datafile 1;
     
    using target database control file instead of recovery catalog

    检查备份文件,发现都是存在的,根本没有问题。最后检查发现是incarnation的问题,因为中间我对该数据库做了一次不完全恢复,做了resetlogs操作。

    RMAN>  list incarnation;

    3       3       EPPS     2179993557       CURRENT 16926695161 23-JAN-15

    解决方法:

       重置数据库的incarnation到2,然后还原数据库,问题解决。关于incarnation的资料,可以参考官方资料7.6.2 Point-in-Time Recovery and Database Incarnations: Concepts

    RMAN> reset database to incarnation 2;
     
    database reset to incarnation 2
