Why do you have to do that? It doesn't say to do that in the documentation. The new datafiles are reflected in the standby controlfile through normal recovery and by issuing the 'alter database create datafile' command.

There is no need to re-dump and copy a new standby controlfile, and definitely no need to shut any database down.
