Linux OS Installation with Reduced Set of Packages for Running Oracle Database Server
Last updated on NOVEMBER 01, 2017
Applies to:Linux OS - Version 2.6.9 to Oracle Linux 5.7 with Unbreakable Enterprise Kernel [2.6.32]
Linux Kernel - Version: 2.6.9 to 2.6.18
The goal of this note is to explain how to configure a Linux system ready to operate as an Oracle Database Server with a reduced set of installed packages.
Limiting the number of installed packages to only those needed provides a smaller footprint for Linux operating system installation and will help to reduce the amount of storage used. A minimal configuration will also help to avoid unnecessary processes and services and result in reduced memory usage, along with a more secure and reliable setup overall.
This document does not intend to list the minimum set of RPMs that are be required for Oracle Database Server installation. Instead, it serves to outline the benefit of using the oracle-validated package that not only pre-configures systems e.g. kernel parameters and user limit settings, but also installs prerequisite packages required to satisfy the Oracle Universal Installer (OUI) as part of Oracle product installation. The oracle-validated package is also used for Oracle Validated Configurations - a collection of pre-tested, certified and supported system configurations.
The text below focuses on having a 'smaller installation footprint' instead of a 'default RPMs' installation that typically results in extra, unnecessary packages, processes and services that are not required for a certified, supported and validated configuration. Still, a 'default RPMs' installation would, however, be sufficient assuming the System Administrator disables non-required services and deinstalls unecessary packages after installation.
