Oracle Linux Installation and Oracle Linux Support Introduction
Oracle Linux can be installed either from a CD-ROM drive or ISO file using the graphical (GUI) installation mode or the text installation mode, as well as over the network using a pre-boot execution environment (PXE). The graphical (GUI) and text installation modes for all of the Oracle Linux 6 releases are similar. Text installation mode has limited capabilities when compared to the GUI installation mode. For example, there is no support for configuring partition layout, storage methods or package selection. To install Oracle Linux using the CD-ROM, ISO file or PXE boot method, visit the Oracle Software Delivery Cloud - Oracle Linux and Oracle VM portal to download the Oracle Linux media. The Oracle Linux media is delivered as a zip file that contains an ISO file. For CD-ROM installations, the ISO file can be burned as a bootable disk and used to install Oracle Linux from a CD-ROM drive.
An Oracle Linux PXE boot installation requires several additional steps; for example, a boot server and a kickstart file to automate the Oracle VM server installation must be created. The boot server allows a bare-metal system to automatically receive an IP address via DHCP, load a kernel via TFTP, and then boot without an operating system. Once the bare-metal server boots, Oracle Linux can be installed using the installation media or a kickstart file to automate the Oracle Linux installation.
Note: Oracle Linux is a Red Hat Enterprise Linux tracking distribution. Oracle offers support for Oracle Linux and Red Hat Enterprise Linux. Red Hat offers support exclusively for Red Hat Linux.
Oracle recommends installing Oracle Linux using the default software package selection without any customization. Using the default software packages without customizations includes most of the prerequisite packages for Oracle technology products and helps limit the number of manual prerequisite checks.
The oracle-rdbms-server-11gR2-preinstall RPM, formally know as oracle-validated, simplifies meeting the software and system configuration prerequisites for installing the Oracle Database, Oracle Enterprise Manager, Oracle E-Business Suite, and many other Oracle technology products on Oracle Linux 6. Installing the oracle-rdbms-server-11gR2-preinstall RPM automatically installs all of the software RPM prerequisites for Oracle Database, Oracle Enterprise Manager, Oracle E-Business Suite, etc..., as well as meeting the system configuration prerequisites, such as creating an oracle user and the oinstall and dba groups, configuring the sysctl.conf settings, system startup parameters, user limits, and driver parameters.
Tip: The oracle-rdbms-server-11gR2-preinstall RPM is available at the Oracle Unbreakable Linux Network, on the Oracle Linux media, and from the Oracle public yum repository.
The Oracle Unbreakable Linux Network and the Oracle public yum server are Oracle' cloud repositories for Oracle Linux and Oracle VM RPMs, software patches, updates and fixes. Access to Unbreakable Linux Network requires an Oracle Single Sign-on account, a valid customer service identifier (CSI) and registration. Access to the Oracle public yum server is open to the public without registration.
The Oracle Unbreakable Linux Network is a cloud resource for Oracle Linux Support customers used to access Oracle Linux and Oracle VM RPM repositories, including software patches, updates and fixes. The Oracle Unbreakable Linux Network portal is located at http://linux.oracle.com
. The Oracle Unbreakable Linux Network portal provides a simple dashboard and management interface for registered Linux systems and RPM channels. The Oracle Unbreakable Linux Network repositories are used to patch and install RPMs for Oracle Linux and Oracle VM systems. Oracle Linux support customers have the option to access patchs and RPMs for Oracle Linux and Oracle VM systems from the Oracle Unbreakable Linux Network using the yum program, or from a local yum repository.
The Unbreakable Linux Network is password protected. Before you can access the Oracle Unbreakable Linux Network you must have a valid Oracle Linux support contract, CSI number and an Oracle Single Sign-on account. Your existing My Oracle Support (MOS) Oracle Single Sign-on account will not work with the Oracle Unbreakable Linux Network until the account has been registered with the Oracle Unbreakable Linux Network. Click the Register
link at the Oracle Unbreakable Linux Network portal to a) create a new Oracle Single Sign-on account or to b) associate your existing Oracle Single Sign-on account with the Oracle Unbreakable Linux Network. Once you have a valid support contract, and CSI number, you can register Oracle Linux systems at the Unbreakable Linux Network by typing “uln_register” as root.
In March 2012, Oracle announced that Oracle Linux 4, 5 and 6 latest RPM patches, updates and erratas are available at no cost from the Oracle public yum server located at http://public-yum.oracle.com. The free Oracle Linux 4, 5 and 6 RPM patches, updates and erratas do not include Oracle support or any of the benefits of the Oracle Linux Support program.
Oracle's public yum server allows us to keep Oracle Linux, Red Hat Enterprise Linux, and Oracle VM system up to date to the latest update version, using the "_latest" RPM repository. The Oracle public yum repository RPMs, patches, updates and erratas do not include Oracle support or any of the benefits of the Oracle Linux Support program.
The Oracle Linux Support program offers the following benefits over and above the free Oracle Linux RPM patches, updates and erratas from the Oracle public yum server:
- Full indemnification against intellectual property claims. Remember the SCO lawsuits?
- Use of the Oracle Enterprise Manager 12c Linux Host Patching feature for patch management. Oracle Enterprise Manager 12c Linux Host Patching feature has feature parity with Red Hat Satellite Server.
- Use of the Oracle Enterprise Manager 12c Virtualization Plug-in for Oracle VM for provisioning, patching, management and monitoring.
- Access to additional Oracle software channels on the Unbreakable Linux Network (ULN).
- Patch channels for each Linux update level.
- The ability to create Support Requests with Oracle' World Class support organization.
The Oracle public yum server latest RPM channel include the base OS version installation RPM packages along with the latest software patches, updates and fixes. Patch jobs using the latest RPM channel update hosts to their respected latest version update with the latest software patches, updates and fixes. A patch job executed on a Oracle Linux 6 host would update the host from 6 to 6U3 with the latest latest software patches, updates and fixes. To keep a host at its respected update level, a valid CSI and the Unbreakable Linux Network is required. With the Unbreakable Linux Network, it is possible to register a host the el*/ol*_base channel along with the el*/ol*_patch RPM channel. When hosts are patched using the el*/ol*_base and el*/ol*_patch RPM channels, the hosts are patched with the latest software patches, updates and fixes from their respected update channel, i.e. 6, 6U1, 6U2 and 6U3.
Oracle Linux Packaging and Support Pricing
Oracle Linux is not a licensed Oracle technology product. The Oracle Linux installation media is freely available from the Oracle eDelivery
Linux portal. Support for Oracle Linux and access to the Unbreakable Linux Network is available as an add-on component of Oracle’s enterprise support package as well as with Sun x86 hardware as an add-on Premier Support for Systems
package. Oracle Linux running on third-party hardware (not on Sun Hardware) is always sold as an add-on
support component of Oracle’s enterprise support package.
