How I Simplified Oracle Database 12c and 11g Installations on Oracle Linux 6

by Ginny Henningsen; updated by Michele Casey
Published September 2012 (updated September 2017)

How to simplify the installation of Oracle Database 12c or 11g on Oracle Linux 6 by installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM package, which automatically performs a number of tasks, such as installing required software packages, resolving package dependencies, and modifying kernel parameters.

READ THIS FIRST: Important Changes Since Publication

While the content in this article is still valid, several details have changed. For example:

For Oracle Database 12c Release 2, the preinstall RPM has a different name than the one used in the article belowpu:

oracle-database-server-12cR2-preinstall

The preinstall RPMs are published on Oracle Linux yum server for both Oracle Linux 6 and 7 in the Latest repositories which are configured and enabled by default in recent releases of Oracle Linux 6 and 7

Introducing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM for Oracle Linux

Before installing Oracle Database 12c or 11g on a system, you need to preconfigure the operating environment since the database requires certain software packages, package versions, and tweaks to kernel parameters. (Be sure to review the appropriate Oracle Database installation guide to familiarize yourself with hardware, software, and operating system requirements.)

Note: This article applies to Oracle Linux 6. A previous article, «How I Simplified Oracle Database Installation on Oracle Linux,» covered performing a similar task on versions of Oracle Linux 5.

On Oracle Linux, I discovered that there is a remarkably easy way to address these installation prerequisites: First, depending on your database version, install either the RPM package called oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall . This RPM performs a number of preconfiguration steps, including the following:

Automatically downloading and installing any additional software packages and specific package versions needed for installing Oracle Grid Infrastructure and Oracle Database 12 c Release 1 (12.1) or 11g Release 2 (11.2.0.3), with package dependencies resolved via yum or up2date capabilities.
Creating the user oracle and the groups oinstall (for OraInventory ) and dba (for OSDBA ), which are used during database installation. (For security purposes, this user has no password by default and cannot log in remotely. To enable remote login, please set a password using the passwd tool.)
Modifying kernel parameters in /etc/sysctl.conf to change settings for shared memory, semaphores, the maximum number of file descriptors, and so on.
Setting hard and soft shell resource limits in /etc/security/limits.conf , such as the locked-in memory address space, the number of open files, the number of processes, and core file size.
Setting numa=off in the kernel for x86_64 machines.

Note that oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall parses the existing /etc/sysctl.conf and /etc/security/limits.conf files and updates values only as needed for database installation. Any precustomized settings not related to database installation are left as is.

The oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPM packages are accessible through the Oracle Unbreakable Linux Network (ULN, which requires a support contract), from the Oracle Linux distribution media, or from the Oracle public yum repository. Thus, whether or not your system is registered with ULN to access Oracle patches and support, you can use oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall to simplify database installation on Oracle Linux. In addition, the Oracle public yum repository now includes all security and bug errata, ensuring systems are secured and stable with the latest security updates and bug fixes.

Installing the oracle-rdbms-server-12cR1-preinstall or oracle-rdbms-server-11gR2-preinstall RPM

The remainder of this article steps through the procedure that I used for installing oracle-rdbms-server-11gR2-preinstall on Oracle Linux via the Oracle public yum repository. The same steps outlined in the following section can be used for either version of the preinstall RPM package. I started with a system running Oracle Linux Release 6 Update 4 for x86_64, a 64-bit version of Oracle Linux that I downloaded from the Oracle software delivery cloud (requires registration or login). First, I set up a yum configuration file that pointed to the correct repository, and then I installed the oracle-rdbms-server-11gR2-preinstall RPM from that repository.

Here are the steps for preconfiguring a system for Oracle Database installation using oracle-rdbms-server-11gR2-preinstall . Remember, the steps are the same when using the oracle-rdbms-server-12cR1-preinstall package; you simply need to change the name of the RPM package during the yum installation step.

As an authorized user (for example, root ), retrieve the file that configures repository locations:

Using a text editor, modify the file, changing the field enabled=0 to enabled=1 to reflect repositories that correspond to the machine’s operating system release.

Here is an excerpt of public-yum-old6.repo with the changed lines in boldface.

Because the target system is running Oracle Linux Release 6 Update 4 for x86_64, which installs the Oracle Unbreakable Enterprise Kernel by default, there are two repositories to enable, [ol6_latest] and [ol6_UEK_latest] .

Next, install the oracle-rdbms-server-11gR2-preinstall RPM using the yum install command. If you are using Oracle Database 12c, then you would type yum install .

The output in Listing 1 shows how the installation checks dependencies and then downloads and installs the required packages.

Listing 1: Installing the oracle-rdbms-server-11gR2-preinstall RPM

The yum installation logs messages about kernel changes in the file /var/log/oracle-rdbms-server-11gR2-preinstall/results/orakernel.log , and it makes backups of current system settings in the directory /var/log/oracle-rdbms-server-11gR2-preinstall/backup .

At this point, the system is ready for the installation of Oracle Database. For example, to install Oracle Database 11g Release 2, follow the directions in Chapter 4, «Installing Oracle Database,» of the Database Installation Guide for Linux.»

Here are the steps I followed while installing Oracle Database 11g Release 2 in my test environment. Make sure you review all documentation and follow recommended best practices before installing into your production environment.

As root , create a parent directory in a file system that has sufficient space to be the target location for the downloaded files:

The amount of disk space needed in the file system varies according to the specific installation type, but roughly twice the size of the zip archives, or 5 GB, is enough to house the software and data files.

Into this target directory, download the installation media files from the Oracle Database Software Downloads page on Oracle Technology Network.

Extract the files:

Log in as the user oracle . Change directory to the database directory and enter the following command to run the Oracle Universal Installer:

The Oracle Universal Installer performs a number of checks, verifying that the necessary OS packages and versions are installed. In addition, it checks kernel parameters set by the oracle-rdbms-server-11gR2-preinstall installation. During the kernel settings check, the installer might flag a few settings as «failed,» and you should investigate these failures. In some cases, you still might be able to continue with the database installation. If you check kernel settings in /etc/sysctl.conf , you’ll see that oracle-rdbms-server-11gR2-preinstall has modified and added the necessary settings to ensure the minimum requirements are met, as defined in section 2.10.1. Below is the list of requirements:

If necessary, you can (as root ) edit the file /etc/sysctl.conf to specify a setting manually, for example:

The Oracle Universal Installer performs additional checks, such as verifying the glibc version, sufficient disk space, environmental variable and path settings, and sufficient physical memory and swap space. Generally, installing oracle-rdbms-server-11gR2-preinstall takes care of the prerequisites so that you can proceed directly with installing the database.

Final Thoughts

Installing the oracle-rdbms-server-12cR1-preinstall and oracle-rdbms-server-11gR2-preinstall RPMs can save time when installing Oracle Database 12c and 11g on Oracle Linux. These RPMs address most Oracle Database installation prerequisites and greatly simplify the installation process.
