Oracle Linux 7 Pre-Install RPM available for EBS 12.1 and 12.2
The Linux Pre-Install RPM for Oracle E-Business Suite Release 12.1 and 12.2 on Oracle Linux 7 is now available for use by customers.
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 public yum repository. It is recommended that this x86_64 Pre-Install 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 Release 12.
As with the Oracle Database Pre-Install RPMs, this RPM provides all required E-Business Suite packages for both the 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).
This Pre-Install 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 (12.1, 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

Hi,
after installing the new RPM and after rebooting the server it rebooted with the wrong version of kernel.
Later we found out that the installation added few boot options and recreated the grub configuration by running grub2-mkconfig, which re-ordered the entries in the /boot/grub2/grub.cfg, and as the order of menu entries was different it booted the wrong kernel.
Suggestion: after installing the rpm make sure the right kernel will be booted by following this document: https://docs.oracle.com/cd/E52668_01/E54669/html/ol7-grub2_bootloader.html
regards,
Maris
Hello Maris -
Thanks for this feedback. While we did not see this issue in our testing, could you file a Service Request (on My Oracle Support) against the 'Linux OS' product outlining the issue you found? Let me know the SR number and I will be happy to follow up as well on this to ensure this progresses.
Regards,
John
Hi John,
I created SR 3-12688212041. But I didn't find the "Linux OS" in the product dropdown, so I created it under eBS installation issues (Oracle Applications DBA). I hope you'll be able to hijack that SR.
thanks,
Maris
Hi again,
FYI, I've received the following on my SR: This is a known issue and Development team is currently working on this issue via unpublished bug 20734786.
The workaround is to set the required kernel back manually after the rpm is installed.
regards,
Maris
