    最终解决办法:使用不完全恢复

    SQL> alter system set "_allow_resetlogs_corruption"=true scope=spfile;

    System altered.

    SQL> startup force
    ORACLE instance started.

    Total System Global Area 285212672 bytes

    Database mounted.
    ORA-01589: must use RESETLOGS or NORESETLOGS option for database open

    SQL> alter database open resetlogs;

    Database altered.

    SQL> alter system set "_allow_resetlogs_corruption"=false scope=spfile;

    System altered.
