Installing and Creating Oracle Database 12c on OEL 6.4

No comments
In this post I am going to share the steps for installation off Oracle Database 12c on Oracle Enterprise Linux 6.4.

Software and resources which will be used:

1. Virtual Box 6.0
2. Oracle Enterprise Linux 6.4
3. Oracle Database 12c(

Configuration of Virtual Machine:

OS: OEL 6.4
Hard Disk: 60GB

Oracle Virtual Box installation and Oracle Enterprise Linux steps I will not be sharing here as I have already shared those in my older posts.Please refer link below.

1. Oracle Virtual Box Installation Steps
2. Creating Virtual Machine Steps
3. Installing Oracle Linux Steps
4. Installing Oracle Linux Steps Continued Steps
5. Installing Guest Addition in Machine Steps(Only Guest addition steps needs to be performed from the post).
6. Once the Machine is Prepared Below is the configuration ScreenShot.

7. We will install pre-requisite RPM's required for Oracle installation as below command. This would be done from root user.
# yum install oracle-rdbms-server-12cR1-preinstall -y

8. Once the rpm installation is done, as OS user with name oracle will be created. Change the password for  oracle user.

9. Add vboxsf group to user oracle. This is optional step. I am doing this step as I will keep by Orace database base software in shared folder between host system.

[root@myprimarydb Desktop]# usermod -aG vboxsf oracle
[root@myprimarydb Desktop]# id oracle
uid=54321(oracle) gid=54321(oinstall) groups=54321(oinstall),492(vboxsf),54322(dba)

10. Disable firewall

11. Edit /etc/selinux/config, here change the parameter SELINUX=disabled
#vi /etc/selinux/config

12. Now set the hostname, and edit /etc/hosts. I will assign IP on eth1 adapter i.e. my Host Only Adapter for hostname.

13. Make sure below values are setup in configuration files.

 * hard nofile 65536
 * soft nofile 4096
 * hard nproc 16384
 * soft nproc 2047
 * hard stack 16384
 * soft stack 10240
14. Reboot the server.

15. Unzip the database software and execute runInstaller.
