The package (oracle-ebs-server-R12-preinstall) is available on the ‘addons’ channel on the Oracle Unbreakable Linux Network (ULN, which requires a support contract) or from the Oracle Linux yum server. It is recommended that this preinstallation RPM be installed on top of a ‘minimal’ installation of Oracle Linux to provide just the necessary packages to install and run Oracle E-Business Suite.

As with the Oracle Database Preinstallation RPMs, the Oracle E-Business Suite Preinstallation RPM provides all required Linux packages for both the EBS application and database tiers while configuring the systems with particular kernel and other values to meet requirements published in our Linux x86-64 Installation and Upgrade Notes (see below).

The E-Business Suite Preinstallation RPM will significantly reduce the preparation time of an environment prior to installing, upgrading or cloning an E-Business Suite R12 instance by performing the following tasks:

  • downloading and installing all software package versions and dependencies required for installing E-Business Suite R12 (12.2, 12.1)
  • 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
