ORACLE DATBASE 12C INSTALLATION ON LINUX 64-bit

This is my first article  on Oracle database 12c. I have installed oracle database 12cR1 on Oracle Enterprise Linux 5.7 - 64 bit virtual mahcine with 4GB RAM, 6GB SWAP and 15 GB of HDD space.

I do not find much difference in Installation steps in oracle 12c when compare it with 11g. There are indeed certain new options and some more per-requisite OS packages.

You can download the software from OTN or EDELIVERY  website.
