Are you using rman for backup and recovery? If your version is 9i or later you can use the duplicate command to create a copy of the database. It is very easy!

I am wondering is that possible to just create a similar database by just copy all this system,indx,tablespace file into the new database oradata folder? Thank in Advance.
