Introducing the oracle-validated RPM for Oracle Linux 6

Before installing Oracle 11g on a Linux system, you need to pre-configure 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.)
On Oracle Linux, I discovered that there is a remarkably easy way to address these installation prerequisites: First install an RPM package called oracle-rdbms-server-11gR2-preinstall. This RPM performs a number of pre-configuration steps, including:

Note that 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 pre-customized settings not related to database installation are left as is.

The oracle-rdbms-server-11gR2-preinstall  RPM package is 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-11gR2-preinstall to simplify database installation on Oracle Linux. Keep in mind, however, that the Oracle public yum repository is not updated with security updates and bug fixes, so the best way to maintain up-to-date and secure systems is with a ULN subscription.

Installing the 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. I started with a system running Oracle Linux Release 6 Update 3 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 pre-configuring a system for Oracle Database installation using oracle-rdbms-server-11gR2-preinstall:

  1. As an authorized user (for example, root), retrieve the file that configures repository locations:
  2. # cd /etc/yum.repos.d
    # wget http://public-yum.oracle.com/public-yum-ol6.repo
    
  3. 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-ol6.repo with the changed line in boldface.

    .
    .
    .
    [ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1 . . .

    Because the target system is running Oracle Linux Release 6 Update 3 for x86_64, there are two repositories to enable, [ol6_latest] and [ol6_UEK_latest]. 

  4. Next, install the oracle-rdbms-server-11gR2-preinstall RPM using the yum install command.

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

    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..

  5. 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.

    The directions instruct you to do the following:

    1. As root, create a parent directory in a file system that has sufficient space to be the target location for the downloaded files:
      # mkdir /home/OraDB11g
      # cd /home/OraDB11g
      

      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.

    2. Into this target directory, download the installation media files from the Oracle Database Software Downloads page on Oracle Technology Network.
    3. Extract the files:
      # unzip linux.x64_11gR2_database_1of2.zip
      # unzip linux.x64_11gR2_database_2of2.zip 
      
    4. Log in as the user oracle. Change directory to the database directory and enter the following command to run the Oracle Universal Installer:
      $ cd /home/OraDB11g/database
      $ ./runInstaller 
      

      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-validated 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-validated recommends different settings for Oracle Database 10g than for Oracle Database 11g. If necessary, you can (as root) edit the file /etc/sysctl.conf to specify a setting manually, for example:

      # vi /etc/sysctl.conf 
      # /sbin/sysctl -p
      

      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-validated takes care of the prerequisites so that you can proceed directly with installing the database.

Note:
Please note that the installer in earlier releases of 11g Release 2 (11.2.0.1 and 11.2.0.2) will show "missing package" failures; e.g. for the pdksh package. These can safely be ignored, the ksh package (which is the successor of pdksh) has already been installed by the preinstall RPM. This bug was fixed in version 11.2.0.3 of the installer.


Now you can log in as the user oracle. Change directory to the database directory and enter the following command to run the Oracle Universal Installer:

$ cd /home/OraDB11g/database
$ ./runInstaller
