Cloning a db is not really the same as DR. But anyway...

We have a tool to clone an ORACLE_HOME, so that it contains all the same binary patches etc from the source

To clone a database, the easiest way is with RMAN duplicate. Also, pretty much a one-line operation, once the preliminaries are setup

https://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmdupdb.htm#BRADV010

So that will give you a replica of the software, and of the database.

If you want to keep that database in sync, then you are looking at Data Guard.
