Dear readers, I decided to finally get around to installing Oracle 12c (12.1.0) on Oracle Linux 6 today. One key difference is the increased disk space requirements from 11g to 12c for the basic database configuration. I recall that 11gR2 requires almost 4GB of disk storage space. Now, for a basic enterprise installation with Oracle 12c, you need at least 6.4Gb of disk space!
Pre-requisites for Oracle Linux 6 with Oracle 12c
Oracle Linux 6 requirements are available online from Oracle documentation. To simplify package and OS dependency requirements, you can deploy the Oracle Linux 6 RPM available from Oracle called oracle-rdbms-server-12cR1-preinstall
Wim Coekerts has a good write up on this:

Like the previous setup screens for 11gR2 we have choice of desktop versus server class database system with Oracle so I will not bore you with these details.
Now we have the new choice to configure the database and also the new multi-tenant feature called pluggable database
One difference in the configuration lies instead of using the Oracle Enterprise Manager (OEM) console, Oracle 12c installer now asks you if you wish to use the new Oracle 12c Cloud Control. Since for sake of first setup with 12c, we are not using this option, we ignore it.
Now we are off to the races for the actual installation for 12c:
At the end, run the usual root.sh scripts that are called out for under root user.
We verify the status of the newly created Oracle 12c database:
The new Oracle 12c management console has a host of new features as shown below that we will explore in future posts:
