Oracle OL7 OS for Oracle EBS R12.2 Prep

What’s ahead

Running Oracle ERP

To run Oracle ERP you need a proper Operating System that is certified by Oracle. 

However. it is not enough to just chose a certified OS.  The OS needs to be pre-prepped so that these tools will not only install properly but also run properly and efficiently.

Which OS?

Oracle Fusion and Oracle EBS run on a variety of OS’s and the choice of which one to use relates to each individual case and the that is beyond the scope of our destiny here today.

We are here to focus on spinning up a version 6 Oracle Linux (OL). It’s free, it’s solid and it can the full process to get it ready is under 20-30 minutes depending on the Linux, AWS, Bash and Oracle skill level of the creator. 

Certified Operating System

Pretty much standard nowadays is the use of Linux for running things.

We will run the certified  Linux x86-64 Oracle Linux 7.

Get it here OracleLinux-R7-U9-Server-x86_64-dvd

(Oracle EBS R12.2.12 is certified onLinux x86-64 Oracle Linux 7)

Some Assumptions

• Reasonable ability to get around Linux
• Familiar with Amazon AWS instances
• Amazon AWS Account
• PuTTy installed (or just use cmd on Macs)
• MS Remote Desktop installed

The Process

Create the Virtual Box Instance of OL7

Update and Install Oracle required

Install tools to access the newly Oracle prepped Instance

First up – Create a Virtual Box Machine

Create a Virtual Box Instance with at least 2GB RAM .

At this point this is all OS prep based stuff so the volume the OS comes on is 15GB so no additional Volumes need to be created.

Next up – The Required Oracle Bits

sudo yum install oracle-database-server-12cR2-preinstall.x86_64 wget nano -y

sudo yum install oracle-epel-release-el7.x86_64 -y

Edit oracle-linux-ol7.repo and set "ol7_addons" to enabled

sudo yum install oracle-ebs-server-R12-preinstall.x86_64 -y

sudo passwd oracle

Install a Desktop Remote & Desktop Utility

Time to install xfce Desktop (a lightweight desktop that allows us to manage the OS) outside a cli. More importantly is that such a setup guards against install fails due to disconnections.

Sure you could run something like xming and run the install with a local X provider. However if that gets disconnected the session is lost.

We install xrdp which is a facility that allows us to skip using a VNC client and instead run Windows Remote Desktop to connect

We install xfce desktop and xrdp  using the epel-release repo

sudo yum install tigervnc-server xrdp firefox rsync -y 

sudo systemctl disable firewalld.service

sudo systemctl stop firewalld.service

sudo yum groupinstall xfce -y

sudo chkconfig xrdp on
su oracle

cd /home/oracle

echo "xfce4-session" > ~/.Xclients

chmod a+x ~/.Xclients 
exit

sudo service xrdp start

Create Swapfile

Just about any Oracle install requires some form of Swap facility. The steps below create a 4G swap facility in file form

In Closing

This process is painless and gets easier everytime you do it.

Keep in mind that so many of Oracle’s tools can run on this configuration such as Oracle Databases, Oracle Middleware etc

It’s the OS for Oracle that just keeps on giving!

Hope you enjoyed it.
