For 10g R2 (32-bit) on RHEL 4 x86, required following package versions or higher.

Part I: Installing Linux

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

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 basicdatabase install is a single CPU, 1024MB of RAM, and one disk drive (IDE, SCSI, or FireWire) with atleast 7GB of free space.

1. Boot the server using the first CD.o 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.o Select Enter to continue with a graphical install on the console. (For other installation

methods and options, refer to the Red Hat Installation Guide.)

o The installer scans your hardware, briefly displays the Red Hat splash screen, and

then begins a series of screen prompts.3. Language Selection

o Accept the default.4. Keyboard Configuration

o Accept the default.5. Welcome Screen

o Click on Next.6. Disk Partitioning Setup

o A thorough treatment of disk partitioning is beyond the scope of this guide, whichassumes that you are familiar with disk partitioning methods.

(WARNING: Improperly partitioning a disk is one of the surest and fastest ways towipe out everything on your hard disk. If you are unsure how to proceed, stopand 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 softwareand contains the following partitions:- 100MB /boot partition-1,500MB swap partitionSet this to at least twice the amount of RAM in the systembut to no more than 2GB. (Thirty-two-bit systems do not support swap files largerthan 2GB.) If you need more than 2GB of swap space, create multiple swap partitions.-7,150MB root partitionThis partition will be used for everything, including /usr,/tmp, /var, /opt, /home, and more. This approach is purely to simplify installation forthe purposes of this guide. A more robust partitioning scheme would separate thesedirectories onto separate filesystems.

7. Boot Loader Configurationo Accept the default.

8. Network Configurationo It is usually best to configure database servers with a static IP address. To do so, clickon Edit .

o A pop-up window appears. Uncheck the Configure using DHCP box, and enter the IPAddress and Netmask for the server. Be sure that Activate on boot is checked, andclick on OK .

o In the Hostname box, select manually and enter the hostname.o In the Miscellaneous Settings box, enter the remaining network settings.

9. Firewall Configurationo For the purposes of this walk-through, no firewall is configured. Select No firewallo Select Disabled on the "Enable SELinux" drop down list.o Click on Proceed when the "Warning - No Firewall" window appears.

10. Additional Language Supporto Accept the default.

11. Time Zone Selectiono Choose the time settings that are appropriate for your area. Setting the system clockto UTC is usually a good practice for servers. To do so, click on System clock uses

UTC.12. Set Root Password

o Enter a password for root, and enter it again to confirm.13. Package Installation Defaults

o Select Customize software packages to be installed.14. Package Group Selection

o Select only the package sets shown here and leave all others unselected.o Desktop

Verifying Your Installation

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

Check your kernel version by running the following command:

uname -r2.6.9-22.ELsmp

Once you've completed the steps above, all of the packages required for Oracle Database 10g Release2 will have been installed. Verify this using the example below.Required package versions (or later):

binutils-2.15.92.0.2-10.EL4 compat-db-4.1.25-9 control-center-2.8.0-12 gcc-3.4.3-9.EL4 gcc-c++-3.4.3-9.EL4 glibc-2.3.4-2

Installing Required Packages

1. Applications System Setting Add Remove Application and select appropriate package.2. Login as root user and navigate to /media/cdrecoder/Enterprise/RPMS and install package3. Login as root user and execute package installation command on terminal

$ cd /media/cdrecoder/Enterprise/RPMS

Part II: Configuring Linux for Oracle

Now Linux Operating system is installed, you need to configure it for Oracle. This section walks throughthe steps required to configure Linux OS for Oracle Database 10g Release 2.

1. Edit the /etc/hosts file must contain a fully qualified name for the server: Example: 192.168.1.230 LinuxDB.sadtex.com LinuxDB

2. Login as root user and Right Click On Desktop Open Terminal ( or su root if already open)

3. Execute xhost +

-- Optional (xhost +, DISPLAY=:0.0; exportDISPLAY)

4. Create the Oracle Groups, User Account named oracle and set oracle user password

/usr/sbin/groupadd oinstall /usr/sbin/groupadd dba/usr/sbin/groupadd oper

/usr/sbin/useradd -g oinstall -G dba,oper oracle/usr/bin/passwd oracle

5. Create Directories, and assign ownership to oracle usermkdir -p /oradisk/app/oraclechown -R oracle:oinstall /oradisk/app/oraclechmod -R 775 /oradisk/app/oracle

6. With an editor open /home/oracle/.bash_profile and add the entries at bottom of file.

umask 022

TMP=/tmp; export TMPTMPDIR=$TMP; export TMPDIREDITOR=gedit export EDITORORACLE_HOSTNAME=LinuxDB.sadtex.com; export ORACLE_HOSTNAME

PATH=/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin; export PATHLD_LIBRARY_PATH=/usr/lib:/usr/X11R6/lib; export LD_LIBRARY_PATH

ORACLE_BASE=/oradisk/app/oracle; export ORACLE_BASEORACLE_HOME=$ORACLE_BASE/product/10.1.0/db; export ORACLE_HOMEORACLE_SID=orcl; export ORACLE_SIDPATH=$ORACLE_HOME/bin:$PATH; export PATH

After editing/saving .bash_profile file check it working properly, showing exact values.

$ su oracle$ echo $TMP$ echo $TMPDIR$ echo $ORACLE_HOSTNAME$ echo $ORACLE_BASE

$ echo $ORACLE_HOME$ echo $ORACLE_SID$ echo $PATH

7. Configuring the Linux Kernel Parameters

Edit file /etc/sysctl.config in any editor and add following lines in bottom of file

kernel.shmall = 2097152kernel.shmmax = 536870912kernel.shmmni = 4096kernel.sem = 250 32000 100 128fs.file-max = 65536net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default=262144net.core.wmem_default=262144net.core.rmem_max=262144net.core.wmem_max=262144

The kernel changes made previously take effect with each reboot. Issue this command to set thekernel parameters:

/sbin/sysctl -p

8. Increase the shell limits by adding following lines in /etc/security/limits.conf file

oracle soft nproc 2047oracle hard nproc 16384oracle soft nofile 1024oracle hard nofile 65536

Add or edit the following line in the /etc/pam.d/login file, if it does not already exist:

session required /lib/security/pam_limits.so

if [ $USER = "oracle" ]; thenulimit -u 16384 -n 65536fi
