Have you read and followed ALL of the installation instructions in the install guide?
Thanks rp0428 for the kind reply. Unfortunately havent read all the stuff yet - could you please point me to the exact URL in oracle (I went through this link http://docs.oracle.com/cd/E24628_01/doc.121/e25353/overview.htm#BABCJEIE haven't seen any directory locations though - maybe I am missing something ???)..
just needed the info pretty quick and a direct answer will be very much appreciated though..
Is Google broken for you? You shouldn't even be installing an app like that if you haven't read the installation instructions.
If you 'just needed the info pretty quick' you shouldn't be using the forums when you can just search for 'Oracle 12c Cloud Control' and there it is right on the first page.
How do you expect to be successful installing or using any Oracle product if you can't do a simple web search?
First off, the only EM CC release out right now is 220.127.116.11, not sure where you got 18.104.22.168 (DB Plugin maybe?).
Second, you're confusing EM CC homes with DB/Grid homes.
EM CC will need it's own Oracle Home (i.e. /opt/oracle/product/em_22.214.171.124). You will need to provide repository database connection information, but EM does not care what home the db or grid is installed in.
I would recommend reviewing the documentation as well as the references on OTN -
Thanks very much Aman.. sure these links helped.
