Preparing Linux OS for 12c installation
Oracle Corporation provides the ability for developers to create a complete development suite on their personal windows desktop or laptop without requiring the expensive equipment required for a true production system. This article outlines the process for configuration of Oracle Enterprise Linux 6.5 installation in preparation for installation of Oracle 12c RDBMS.
NOTE: This process can be used for most Linux installations, regardless of original company or organization providing the base Linux OS.

1. Logon to your Windows desktop/laptop as an administrator and open Oracle VirtualBox.
2. Logon to your Linux Server as the root user and create the group “dba” and user account “oracle” to be your oracle software owner with the following commands:
groupadd dba
useradd oracle -g dba -G root
passwd oracle

3. Create the following directory structures to support your oracle software installation with the commands:
mkdir /opt/app
mkdir /opt/app/oracle
mkdir /opt/app/oracle_software
mkdir /opt/app/oracle_inventory
mkdir /opt/app/oracle_inventory/inventory

4. Change ownership of directory structures to the oracle software owner with the following commands:
chown oracle:dba /opt/app
chown oracle:dba /opt/app/oracle
chown oracle:dba /opt/app/oracle_software
chown oracle:dba /opt/app/oracle_inventory
chown oracle:dba /opt/app/oracle_inventory/inventory

5. Change the ownership of the Oracle RDBMS media files downloaded in Part 9 of this serious to the oracle software owner with the following commands:
chown oracle:dba /opt/app/oracle_software
chown oracle:dba /opt/app/oracle_software/*
chmod 777 /opt/app/oracle_software/*

6. Switch to the oracle software owners account and change directory back to /opt/app/oracle_software location.
[root@oel65 oracle_software]# su – oracle
[oracle@oel65 ~]$ cd /opt/app/oracle_software
[oracle@oel65 oracle_software]$

7. Unpack all the mediate files with the following command: “find . -name “*.zip” -exec unzip {} \;”
[oracle@oel65 oracle_software]$ find . -name “*.zip” -exec unzip {} \;
…
..
inflating: database/response/netca.rsp
inflating: database/response/dbca.rsp
inflating: database/response/db_install.rsp
[oracle@oel65 oracle_software]$

8. This completes the setup of the VM Enterprise Linux for Oracle 12c RDBMS installation.
