Installing Oracle Database 12cR2 on Linux 7.3
What do you do when Oracle releases the long awaited 12cR2 version of the database? You download it and install it. So let’s get started.
Visit the Oracle Download site and download the version 12cR2 of the database. This time it’s just a single zip file. So grab that and unzip it in a directory on your linux box. Below we will configure your OS and walk through the install screens.

4. Create your install directory structure and assign appropriate permissions:
mkdir -p /u01/app/oracle/product/126.96.36.199/db_1

For the rest of this process, you will need to log in as the Oracle user. If you used the preinstall package you’ll need to set your ORACLE user password:
6. Login as the oracle user and unzip the “linuxx64_12201_database.zip” you downloaded earlier.
7. Execute the ./runInstaller file to kick off the installation
15. From here, take all the remaining defaults and and finally click Install.
