Oralce Linux 6 OS & Oracle 11g DB Installation

Linux 6 installation followed by oracle 11g Release 2 database installation on a machine with 8GB RAM.

1. Boot from the Oracle Linux 6 DVD. At the boot screen select "Install or upgrade an existing system" and press "Enter".

2. The next screen test the media DVD before the installation starts. This will take long time so use the TAB key and when the focus is on SKIP button press ENTER.
3. On the "Welcome" screen, click the "Next" button.
4.Select the appropriate language, then click the "Next" button.
5.Select the relevant keyboard setting, then click the "Next" button.

7.Click the "Re-initialize all" button on the disk initialization warning dialog.8.Enter a fully qualified host name, then click the "Configure Network" button.
9.Highlight the relevant connection and click the "Edit" button.
10.Check the "Connect automatically" checkbox. If you are not using DHCP, click on the "IPv4 Settings" tab, set the method to "Manual", click the "Add" button and enter the appropriate network details. When you are happy with the details, click the "Apply" and "Close" buttons to return to the host name screen, then click the "Forward" button.
11.Select the relevant time zone by clicking on your nearest city on the map. Click on the "Next" button to proceed.
12.Enter a root password for the server, then click the "Next" button to proceed.
13.Check the partitioning type you require. If you want to amend the default partitioning layout, check the "Review and modify partitioning layout" option. Click the "Next" button.

17.The "Package Group Selection" screen allows you to select the required package groups, and individual packages within the details section. When you've made your selection, click the "Next" button. If you want the server to have a regular gnome desktop you need to include the following package groups from the "Desktops" section:

◦Desktop Platform
◦General Purpose Desktop
◦Graphical Administration Tools
◦X Windows System
18. Now you can wait and relax for the installation to complete.
19.Click the "Reboot" button to complete the installation.

31. Finally, Disable SELinux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
Once the change is complete, restart the server.

Now the following is about Installing Oracle database 11g on the above installed Oracle Linux 6.

Oracle Database 11g Release 2 (11.2) Installation On Oracle Linux 6
The previous post is about Oracle Linux 6 installation and the following article describes the installation of Oracle Database 11g Release 2 (11.2) (64-bit) on Oracle Linux 6 (64-bit). The article is based on a server installation with a minimum of 2G swap, with both SELinux and the firewall disabled. The following package groups were included for this installation.
  • Base System > Base
  • Base System > Client management tools
  • Base System > Compatibility libraries
  • Base System > Hardware monitoring utilities
  • Base System > Large Systems Performance
  • Base System > Network file system client
  • Base System > Performance Tools
  • Base System > Perl Support
  • Servers > Server Platform
  • Servers > System administration tools
  • Desktops > Desktop
  • Desktops > Desktop Platform
  • Desktops > Fonts
  • Desktops > General Purpose Desktop
  • Desktops > Graphical Administration Tools
  • Desktops > Input Methods
  • Desktops > X Window System
  • Development > Additional Development
  • Development > Development Tools
  • Applications > Internet Browser
An example of this type of Linux installations can be seen in my previous post. Alternative installations may require more packages to be loaded, in addition to the ones listed below.
Note. Oracle currently only support 11gR2 on Oracle Linux 6 using the Unbreakable Linux Kernel (UEK).
  • Download Software
  • Unpack Files
  • Hosts File
  • Automatic Setup
  • Manual Setup
  • Additional Setup
  • Installation
  • Post Installation

Download Software

Download the Oracle software from OTN or MOS-Metalink Oracle Support depending on your support status.

Unpack Files

Unzip the files.


You should now have a single directory called "database" containing installation files.

Hosts File

The "/etc/hosts" file must contain a fully qualified name for the server.   
For example.       localhost.localdomain  localhost   ol6-112.localdomain    ol6-112

Automatic Setup

If you plan to use the "oracle-rdbms-server-11gR2-preinstall" package to perform all your prerequisite setup, follow the instructions at to setup the yum repository for OL, then perform the following command.
# yum install oracle-rdbms-server-11gR2-preinstall
All necessary prerequisites will be performed automatically.

Manual Setup

Oracle recommend the following minimum parameter settings.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
The current values can be tested using the following command.
/sbin/sysctl -a | grep 
Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
Run the following command to change the current kernel parameters.
/sbin/sysctl -p
Add the following lines to the "/etc/security/limits.conf" file.
oracle              soft    nproc   2047
oracle              hard    nproc   16384
oracle              soft    nofile  4096
oracle              hard    nofile  65536
oracle              soft    stack   10240
Install the following packages if they are not already present.
# From Oracle Linux 6 DVD
cd /media/cdrom/Server/Packages
rpm -Uvh binutils-2*x86_64*
rpm -Uvh glibc-2*x86_64* nss-softokn-freebl-3*x86_64*

rpm -Uvh compat-libcap*
cd /
Note. This will install all the necessary 32-bit packages for From onwards many of these are unnecessary, but having them present does not cause a problem.
Create the new groups and users.
groupadd -g 501 oinstall
groupadd -g 502 dba
groupadd -g 503 oper
groupadd -g 504 asmadmin
groupadd -g 506 asmdba
groupadd -g 505 asmoper

useradd -u 502 -g oinstall -G dba,asmdba,oper oracle
passwd oracle
Note. We are not going to use the "asm" groups, since this installation will not use ASM.

Additional Setup

Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
Once the change is complete, restart the server.
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01
Login as root and issue the following command.
xhost +
Login as the oracle user and add the following lines at the end of the ".bash_profile" file.
# Oracle Settings
TMP=/tmp; export TMP

ORACLE_HOSTNAME=ol6-112.localdomain; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME

PATH=/usr/sbin:$PATH; export PATH



Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
Proceed with the installation of your choice. The prerequisites checks will fail for the following version-dependent reasons:
  • The installer shows multiple "missing package" failures because it does not recognize several of the newer version packages that were installed. These "missing package" failures can be ignored as the packages are present. The failure for the "pdksh" package can be ignored because we installed the "ksh" package in its place.
  • The installer should only show a single "missing package" failure for the "pdksh" package. It can be ignored because we installed the "ksh" package in its place.
  • The installer shows no failures and continues normally.
