About Minimal Linux Installations. To complete a minimal Linux installation, select one of the minimal installation options (either a custom installation where you select the Minimal option from Package Group Selection, or where you deselect all packages except for the Base pack). This installation lacks many RPMs required for database installation, so you must use an RPM package for your Oracle Linux release to install the required packages. The package you use depends on your Linux release, and your support status with Unbreakable Linux Network (ULN). Note. The Oracle Preinstallation RPM installs the X1. X Window System server packages. To use graphical user interfaces such as OUI, configuration assistants, and Oracle Enterprise Manager, set the display to a system with X Window System server packages. Refer to the following URL for documentation regarding installation of a reduced set of packages: https: //support. CSP/main/article? NOT& id=7. 28. Note. If you are not a member of Unbreakable Linux Network or Red Hat Support network, and you are a My Oracle Support customer, then you can download instructions to configure a script that documents installation of a reduced set of packages.

About Oracle Linux and the Unbreakable Enterprise Kernel. Oracle's Unbreakable Enterprise Kernel delivers the latest innovations from upstream development to customers who run Oracle Linux in the data center. The Unbreakable Enterprise Kernel is included and enabled by default starting with Oracle Linux 5 Update 6. The Unbreakable Enterprise Kernel is based on a recent stable mainline development Linux kernel, and also includes optimizations developed in collaboration with Oracle Database, Oracle middleware, and Oracle hardware engineering teams to ensure stability and optimal performance for the most demanding enterprise workloads. Oracle highly recommends deploying the Oracle Unbreakable Enterprise Kernel in your Linux environment, especially if you are running enterprise applications. However, using Oracle Unbreakable Enterprise Kernel is optional. If you require strict Red Hat Enterprise Linux kernel (RHEL) compatibility, then Oracle Linux also includes a kernel compatible with the RHEL Linux kernel, compiled directly from the RHEL source code. You can obtain more information about the Oracle Unbreakable Enterprise Kernel for Linux at the following URL: https: //www. The Oracle Unbreakable Enterprise Kernel for Linux is the standard kernel used with Oracle products.
