The document outlines the installation process of Oracle 12cR2 on Linux with ASM, detailing steps such as connecting to an OEL server, configuring ASM disk groups, and installing Oracle software. It includes instructions for creating partitions, configuring user profiles, and setting up the database using DBCA. The steps also highlight the need to run specific scripts as the root user and ensure proper user configurations for successful installation.

1. ORACLE 12CR2
