register a layer with sde in a feature dataset

Question

I am using arcgis 10.2 with geodatabase.

I want to use the command 
sdelayer -o register 
to register an oracle spatial table with sde.
but I want to register it inside a feature dataset.
I didn't see a way to do that in the command line.

One more related problem
I registered the layer normally, and they I tried to move it to the feature dataset with arccatalog
but I was not able to do that, because I got the "unavailable" icon when the layer is over the feature dataset
although both (layer and feature dataset) share the same coordinate system

I remember that registration has two phases, register with SDE and register with Geodatabase, and I  never understand what the difference between them.
So, my question, if I want to write a python script to register with the geodatabase, which arcpy commands I can use?
and do I have to register it with SDE first?

No, you don't. ArcSDE registration is an integral part of registering with the Geodatabase. So once you register a layer with the Geodatabase, it is also registered in ArcSDE system tables (but not the other way around: registering your layer with the "sdelayer" command in ArcSDE won't register it automatically with the Geodatabase).

you can use "arcpy.RegisterWithGeodatabase_management"

check this: http://resources.arcgis.com/en/help/main/10.1/index.html#//00170000000r000000

You cannot use ArcSDE command line tools to add anything to a feature dataset, ever.
Tools written with just the ArcSDE API are not geodatabase-aware.  Only ArcObjects-based
tools like ArcPy can manage feature dataset management.

That explain what I found that using that sde command "SdeLayer" didn't register the feature class in the geodatabase.
Because I found that when I right-mouse click on it and show the context menu, the option "Register with geodatabase" is available.
