There is no reason why DD should not work if everything was done
correctly. Are you sure you are using it right? Depending on platform
you have to specify several first blocks in a raw device to be skipped
(skip=number), because a data part of raw devices starts after these
blocks. Check this with your sysadmin, he should know.
If you are not experienced with RMAN then DD is probably a safer way to
go for you. I can not write here RMAN guide, but as guidance for futher
study: when creating standby by RMAN, you have to perform a standard
restore to the target location, but using "duplicate target database
for standby nofilenamecheck;" command which will restore your most
recent primary backup as a standby and leaves your newly created
standby in MOUNTED state prepared for subsequent steps (see Data Guard
Concepts and Administration).
