配置Oracle 11g R2 Datagurad出現ORA-10458錯誤

備庫：
SQL> alter database open read only;
alter database open read only
*
ERROR at line 1:
ORA-10458: standby database requires recovery
ORA-01152: file 1 was not restored from a sufficiently old backup
-
 

ORA-01110: data file 1: '/u01/app/Oracle/oradata/bhoms/system01.dbf'

查看備庫：
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;

SWITCHOVER_STATUS
--------------------
TO PRIMARY

查看主庫：
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;

SWITCHOVER_STATUS
--------------------
NOT ALLOWED

再次查看主庫的參數：
SQL> show parameter LOG_ARCHIVE_DEST_2

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_2                   string      service=standby lgwr async noa
                                                 ffirm
原來這里設置錯誤：
SQL> alter system set log_archive_dest_2='service=bhoms02 async valid_for=(online_logfiles,primary_role) db_unique_name=bhoms02';

再查主庫：
SQL> SELECT SWITCHOVER_STATUS FROM V$DATABASE;

SWITCHOVER_STATUS
--------------------
TO STANDBY

查看備庫：
SQL> show parameter LOG_ARCHIVE_DEST_2

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
log_archive_dest_2                   string      service=standby lgwr async noa
                                                 ffirm
原來這里設置錯誤：
SQL> alter system set log_archive_dest_2='service=bhoms01 async valid_for=(online_logfiles,primary_role) db_unique_name=bhoms01';

重啟備庫，解決問題：
SQL> shutdown immediate;
ORA-01109: database not open

Database dismounted.
Oracle instance shut down.
SQL> startup nomount
Oracle instance started.
