客户的主数据库是一套Oracle Database 11gR2 for AIX的单机数据库，在系统层面部署了IBM HACMP软件，将该数据库做成了能在两台物理机之间切换的主备模式，并且为该数据库实施了ADG。客户将主数据库切换到备用服务器之后，，主数据库与备用数据库不再同步，在数据库的告警日志中收到如下告警：

Fri Mar 13 02:28:00 2015
PING[ARC2]: Heartbeat failed to connect to standby 'd012dg'. Error is 16057. Fri Mar 13 02:29:01 2015

PING[ARC2]: Heartbeat failed to connect to standby 'd012dg'. Error is 16057.

以上告警在ADG的环境中已经多次遇到，请注意类似报错的错误ID，这里的ID是16057，Oracle对该错误是这样解释的：
ORA-16057: DGID from server not in Data Guard configuration
Cause: The Data Guard name of the primary database or the FAL server is not in the Data Guard configuration of the standby.

Action: In order for the primary database or the FAL server to archive logs to the standby database, the Data Guard name of the primary or FAL server must be in the Data Guard configuration of the standby.

在MOS中找到如下文章：
