Overview

The guide provides a walkthrough of installing an Oracle Database 10g Release 2 database on commodity hardware for the purpose of evaluation .   If you are new to Linux and/or Oracle, this guide is for you. It starts with the basics and walks you through an installation of Oracle Database 10g Release 2 from the bare metal up.

This guide will take the approach of offering the easiest paths, with the fewest number of steps for accomplishing a task.  This approach often means making configuration choices that would be inappropriate for anything other than an evaluation.  For that reason, this guide is not appropriate for building production-quality environments, nor does it reflect best practices.

The Linux distributions certified for Oracle Database 10g Release 2 are:

  • Oracle Enterprise Linux 5 (OEL5)
  • Oracle Enterprise Linux 4 (OEL4)
  • Red Hat Enterprise Linux  5 (RHEL5)
  • Red Hat Enterprise Linux  4 (RHEL4)
  • Red Hat Enterprise Linux 3 (RHEL3)
  • Novell SUSE Linux Enterprise Server 10 (SLES10)
  • Novell SUSE Linux Enterprise Server 9 (SLES9)
  • Asianux 2.0
  • Asianux 1.0

We will cover the RHEL4 and SLES9 distributions only here.

Please note that as an alternative Novell offers the orarun package for installation of SLES9 and Oracle. To use that method instead of the one described here, refer to this Novell-supplied install guide.

This guide is divided into four parts: Part I covers the installation of the Linux operating system, Part II covers configuring Linux for Oracle, Part III discusses the essentials of installing the Oracle Database, and Part IV covers creating additional filesystems and  Automatic Storage Management (ASM)—a new storage option in Oracle Database 10g that greatly simplifies storage administration and management.  The Appendix provides information to help you get started using your new database including how to access the database interactively and how to stop and start the database and related services.


Part I: Installing Linux

This guide assumes a server with the following hardware:

  • 800MHz Pentium III CPU
  • 1024MB of RAM
  • SCSI host adapter (Ultra SCSI 160)
  • Four SCSI disk drives (1 x 9GB + 3 x 36GB)
  • One 100Base-T Ethernet adapter

Your hardware does not have to match this in order to use this guide.  All that is necessary for a basic database install is a single CPU, 1024MB of RAM, and one disk drive (IDE, SCSI, or FireWire) with at least 7GB of free space.

Now, let's walk through the process of installing the Linux operating system on a server. The instructions assume a fresh install of Linux (as opposed to an upgrade), that the server will be dedicated to Oracle, and that no other operating systems or data are on the server.


RHEL4

Oracle Database 10g Release 2 is certified to run the base release of RHEL4 (Advanced Server and Enterprise Server) without updates. If you have update CDs, you can use the boot CD from the update instead of the boot CD from the base release to automatically apply all updates during the installation. All updates from Red Hat are supported by Oracle.

The easiest and fastest way to apply the updates for a fresh install of Linux is to perform the install by using the update CDs. If Linux is already installed or you don't have the updates on CDs, they can be applied through RHN. Because this guide is designed for a fresh Linux install, you'll use the update CDs.

  1. Boot the server using the first CD.
    • You may need to change your BIOS settings to allow booting from the CD.
  2. The boot screen appears with the boot: prompt at the bottom of the screen.
    • The installer scans your hardware, briefly displays the Red Hat splash screen, and then begins a series of screen prompts.
  3. Language Selection
    • Accept the default.
  4. Keyboard Configuration
    • Accept the default.
  5. Welcome Screen
    • Click on Next.
  6. Disk Partitioning Setup
    • A thorough treatment of disk partitioning is beyond the scope of this guide, which assumes that you are familiar with disk partitioning methods.

      (WARNING: Improperly partitioning a disk is one of the surest and fastest ways to wipe out everything on your hard disk. If you are unsure how to proceed, stop and get help, or you will risk losing data!)

      This guide uses the following partitioning scheme, with ext3 for each filesystem:

      The 9GB disk on the first controller (/dev/sda) will hold all Linux and Oracle software and contains the following partitions:
      - 100MB /boot partition
      -1,500MB swap partition—Set this to at least twice the amount of RAM in the system but to no more than 2GB. (Thirty-two-bit systems do not support swap files larger than 2GB.) If you need more than 2GB of swap space, create multiple swap partitions.
      -7,150MB root partition—This partition will be used for everything, including /usr, /tmp, /var, /opt, /home, and more. This approach is purely to simplify installation for the purposes of this guide. A more robust partitioning scheme would separate these directories onto separate filesystems.

  7. Boot Loader Configuration
    • Accept the default.
  8. Network Configuration
    • It is usually best to configure database servers with a static IP address. To do so, click on Edit .
    • A pop-up window appears. Uncheck the Configure using DHCP box, and enter the IP Address and Netmask for the server. Be sure that Activate on boot is checked, and click on OK .
    • In the Hostname box, select manually and enter the hostname.
    • In the Miscellaneous Settings box, enter the remaining network settings.
  9. Firewall Configuration
    • For the purposes of this walk-through, no firewall is configured. Select No firewall
    • Select Disabled on the "Enable SELinux" drop down list. 
    • Click on Proceed when the "Warning - No Firewall" window appears.
  10. Additional Language Support
    • Accept the default.
  11. Time Zone Selection
    • Choose the time settings that are appropriate for your area. Setting the system clock to UTC is usually a good practice for servers. To do so, click on System clock uses UTC.
  12. Set Root Password
    • Enter a password for root, and enter it again to confirm.
  13. Package Installation Defaults
    • Select Customize software packages to be installed.
  14. Package Group Selection
    • Select only the package sets shown here and leave all others unselected. 
    • Desktop
      • X Window System
      • Gnome
    • Applications
      • Graphical Internet (optional)
    • Servers
      • Do not select anything in this group.
    • Development
      • Development Tools
    • System
      • Administration Tools
      • System Tools
        • Add the package 'sysstat' by clicking on the Details link and selecting "sysstat - The sar an iostat system monitoring commands." from the Optional Packages list.
    • Miscellaneous
      • Do not select anything in this group.
    • Click on Next to proceed.
  15. Installing Packages
    • Software will be copied to the hard disk and installed. Change disks as prompted.
  16. Congratulations
    • Remove the installation media from the system, and click on Reboot .
  17. The system automatically reboots and presents a new welcome screen.
    • Click on Next.
  18. License Agreement
    • Read the license agreement. If you agree to the terms, select Yes, I agree to the License Agreement and click on Next.
  19. Date and Time
    • Set the Date and Time.
    • If you want to use an NTP server (recommended), select Enable Network Time Protocol and enter the name of the NTP server.
  20. Display
    • Accept the defaults or change as required.
  21. Red Hat Login
    • Enter your Red Hat Network login and password or create a new one.
  22. System User
    • Create an account for yourself.
    • Do not create an account for oracle at this time. Creating the oracle account is covered later in this section.
  23. Additional CDs
    • Click on Next.
  24. Finish Setup
    • Click on Next.
  25. A graphical login screen appears.
  26. Congratulations! Your RHEL4 software is now installed.

Verifying Your Installation

Required kernel version: 2.6.9-5.0.5.EL  This kernel, or any of the kernels supplied in updates, works with Oracle Database 10g Release 2 .

Check your kernel version by running the following command:

uname -r
                                

Ex:
# uname -r
2.6.9-22.ELsmp

Once you've completed the steps above, all of the packages required for Oracle Database 10g Release 2 will have been installed.  Verify this using the example below.
