dataguard 主库报 ORA-16057 不知道何故

am196

我的dataguard配置完后，一直报这个错，不知道为何，哪位帮我看一下谢谢！
我的是RAC跟一个单实例做的DataGuard rac我只开一个节点。
两端的sys密码文件密码都是一样的。
网络也通，也可以用sys用户连接到对方的数据库
但是主库报ORA-16057

log_archive_config='dg_config=(single,rac1)'

有设置,问题找到了,这个应该是db_unique_name
我设置成服务名了.

LOG_ARCHIVE_CONFIG enables or disables the sending of redo logs to remote destinations and the receipt of remote redo logs, and specifies the unique database names (DB_UNIQUE_NAME) for each database in the Data Guard configuration.

oerr ora 16057
应该会给出答案的  
log_archive_config没有设置吧
