Oracle Linux pre-install RPM for EBS

When deploying Oracle software on a Oracle Linux (or any other Linux distribution) you will have to set a number of pre-requisites. In some cases you need to set certain kernel parameters and ensure you have specific packages installed on your machine.

For the Oracle database there is already for a long time a way of doing this by installing a specific RPM. As this is providing a great way of preparing your environment for the software installation Oracle is also providing a similar mechanism for preparing your environment for the installation of Oracle e-Business suite.

You can install a pre-install RPM for Oracle e-Business Suite 12.1 and 12.2 which you can fetch from the addons channel at ULN. A best practice for creating a new Oracle Linux environment to run Oracle e-Business Suite is to do a minimal installation of Oracle Linux and install the pre-install RPM on top of this. Reason for this is that you will not have unneeded packages and functionality which might cause hindrance at a later stage.

• In essence the pre-install RPM will undertake the following tasks:
• Downloading and installing all software package versions and dependencies required for installing E-Business Suite R12 (12.1, 12.2)
• Creating the users oracle and applmgr for use as owners of the database and application tiers respectively, while setting hard and soft shell resource limits
• Updating kernel parameters in /etc/sysctl.conf to recommended values
• Sets DNS resolver parameters in /etc/resolv.conf to minimum recommended values
• Sets 'numa=off' in the kernel in the kernel commandline
• Disables 'Transparent Huge Pages (THP)' if enabled
