Copying Database

I would like to create a second instance of my database on the same Unix Server.
I was wondering is it possible to copy of all the tablespace, rollback and redo files
to a new destination and then update the copied system tablespace with the new locations
of the tablespaces etc, aswell as creating a new init???.ora file. Is this all there is to it or am I way off base.

Thanks
