ora-02085:的注解是：database link name connects to name cause: the database link attempted to connect to a database with a different name.the name of the database link must be the same name as the name of the database.action: create a database link with same name as the database to which it connects.
意思是:if u set the parameter global_names to true,the db link name connected to this server must equal db_name + db_domain.
很多时候我们只是让dblink的名字等于了db_name,所以创建出错
