搭建DG 打開備庫提示ORA-10458

發生背景：

搭建11g DG ，備庫rman同步後打開備庫提示以下：

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/test/system01.dbf'

查看備庫日誌，發現一堆Error 12154 received logging on to the standby的報錯

查詢主庫：

SQL> select dest_name,status,error from v$archive_dest;

dest_name status ERROR

-----------------------------------------------------------------

log_archive_dest_1 valid

log_archive_dest_2 BAD PARAM ORA-12154: TNS:could not resolve the connect identifier specified I could tnsping the STANDBY from production

..................................................................

分析：log_archive_dest_2是用來指向備庫的，負責將歸檔日誌傳到備庫。

最後發現log_archive_dest_2中的service這裏應該和tnsnames中定義的備庫的服務名一致。修改後open備庫正常打開。
