Hi Sanjay I use cloning to install RDBMS binaries and it's pretty straight-forward. Create a zip archive of the source ORACLE_HOME, extract it on the target, run clone.pl from target $ORACLE_HOME/clone/bin, and then run root.sh. Niall Lichfield wrote a nice how-to here: http://orawin.info/blog/2011/07/27/in-praise-of-clones/ In a previous role I used cloning for Grid Infrastructure too, but not got around to implementing this at my current place. It worked fine, and I don't remember it being too hard to get working. I followed the steps here: http://docs.oracle.com/cd/E11882_01/rac.112/e41959/clonecluster.htm#CWADD03202.
