因为路径不一样可以不加nofilenamecheck dorecover 直接复制吗？
duplicate target database for standby ;

With Standby database being used as Source database for Active duplicate from 11.2.0.4 we have the restriction introduced with respect to the Standby database needing to be in Open state for the active duplicate to work successfully while using Standby as Source. (For Non ADG envirnoment you can just open standby read only ).

Bug 11715084 - Active duplicate should work when connected to Standby as source DB (Doc ID 11715084.8)
