以上错误是因为，没有一致性关库造成的

--使用隐藏参数忽略一致性验证：
conn / as sysdba
startup mount
alter system set "_allow_resetlogs_corruption"=true scope=spfile;
startup force mount;        --将数据库启动到 mount
alter database open resetlogs;    --使用 resetlogs 打开数据库
--此时再报 ORA-01139 错误
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery

解决办法：
recover database until cancel;
Media recovery complete.

alter database open resetlogs;

Database altered.

SQL> select status from v$instance;

STATUS
------------
OPEN

--取消隐藏参数后，可以正常启动数据库：
alter system reset "_allow_resetlogs_corruption" scope=spfile sid='*';
