标题: 搭建DG 打开备库提示ORA-10458
发生背景：
搭建11g  DG ，备库rman同步后打开备库提示如下：

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'

查看备库日志，发现一堆Error 12154 received logging on to the standby的报错
查询主库：
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是用来指向备库的，负责将归档日志传到备库。
最后发现log_archive_dest_2中的service这里应该和tnsnames中定义的备库的服务名一致。修改后open备库正常打开。
