Oracle Database 11g Release 1 (11.1) Installation on Oracle Enterprise Linux 5.0

November 29, 2009 Leave a comment

This article describes the installation of Oracle Database 11g Release 1 (11.1) on Oracle Enterprise Linux 5.0. Here I simulate the installation process based on my PC based server which has following hardware configuration:

  1. Intel 2.4 GHz x86 Processor.
  2. 80 GB SATA HDD
  3. GB physical memory

To make an easy and convenient installation process we documented installation Process in two phases. First of on we have to install Oracle Enterprise Linux Server 5.0 with required package and system parameter. After that in the second phase we simulated installation Process of Oracle 11g with respective screen shot which will help the beginner Administrator to understand their jobs easily. I hope, this article will help the novice and mid level Database/ System Administrator to understand what is the production standard installation of Oracle 11g for mid level traffic processing generally which will done by General Purpose or Transaction processing database template. Its me a great pleasure if this installation cook help someone meet their company requirement.

Part-1: Installing Oracle Enterprise Linux 5.0

You may download Oracle Enterprise Linux 5.0 from oracle technology network. To download Oracle Enterprise Linux 5.0 Enterprise Edition uses the following link.

Installation Process:

  1. Boot the server using the first CD.
    • You may need to change your BIOS settings to allow booting from the CD.

  1. Disk Portioning Step
  • Select Remove all partition on Selected device and create default layout the system  and Click on Next
  • The disk on the first controller (/dev/sda) will hold all Linux software and contains the following partitions:
  • /boot partition  – 256MB
  • Swap Partition -2 GB [Set this to at least twice the amount of RAM in the system But if the Physical RAM equal to 4 GB or greater then choose swap size exactly as memory size.]
  • root (/) partition  –  19 GB This partition will be used for everything, including /usr, /tmp,  /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 file systems.

Part-2: Configuring Linux for Oracle

You may download Oracle 11g from oracle technology network. To download Oracle Database 11g Release 1 (
Standard Edition, Standard Edition One, and Enterprise Edition use the following link.

1. Creating the Oracle Group and User Account

  • Use the following command to add The Oracle Inventory group (oinstall) and OSDBS (dba) Group:
        [root@testdb ~]#  groupadd oinstall
        [root@testdb ~]#  groupadd dba
  • Use the following command to add a user whish is The Oracle software owner (oracle)
        [root@testdb ~]# useradd oracle
  • Use the following command to specify oinstall as the primary group and dba as the secondary group for oracle User.
        [root@testdb ~]# usermod -g oinstall -G dba oracle
  • Finaly use the following command to Check the Oracle user and user group:
        [root@testdb ~]# id oracle
        uid=500(oracle) gid=500(oinstall) groups=500(oinstall),501(dba)
  • Use the following command to set the password of the oracle user:
        [root@testdb ~]# passwd oracle
        Changing password for user oracle.
        New UNIX password:
        Retype new UNIX password:
        passwd:all authentication tokens updated successfully.
  • Use the Following Command determine whether the An unprivileged user (nobody) user exists or Not :
        [root@testdb ~]# id nobody
        uid=99(nobody) gid=99(nobody) groups=99(nobody)

If this command displays information about the nobody user, then you do not

need to create the nobody user.

  • If the nobody user does not exist, then enter the following command to create it:
        # useradd nobody

2. Creating Required Directories and Change the Owner Ship

  • Create directories with names similar to the following, and specify the correct owner, group, and permissions for them:

1. The Oracle base directory (For Oracle Home directory)

2. An optional Oracle data file directory

  • Oracle Recommand that the base directory and data file directory will be different mount point. if you do not create the mount point during the operation system installation then use the following command to create a directory.

mkdir -p /mount_point/app/

For example :

        [root@testdb ~]# mkdir -p /u01/app
  • To set the appropriate owner, group use the following command :
        [root@testdb ~]# chown -R oracle.oinstall /u01
        [root@testdb ~]# chown -R oracle.oinstall /u02
  • To permissions on the directory use the following command :
        [root@testdb ~]# chmod -R 775 /u01
        [root@testdb ~]# chmod -R 775 /u02

3. Verify Hardware Requirements

  • Main Memory Requirements
  • Disk Space Requirements

Main Memory Requirements

  • At least 1 GB of Physical RAM Requirement , To determine the physical RAM size, use the following command:
        [root@testdb ~]# cat /proc/meminfo | grep Mem
        MemTotal:      1018368 kB
        MemFree:         43884 kB
  • Swap Spase

For 512 MB RAM,Swap Space Required Double the size of RAM

For 1024 MB RAM, Swap Space Required 1.5 times the size of RAM

  • To determine the physical RAM size, use the following command:
        [root@testdb ~]# cat /proc/meminfo | grep SwapTotal
        SwapTotal:     2096472 kB

Disk Space Requirements

  • Oracle Recommend For Enterprise Edition you may need 3.47 GB, Enterprise Edition require 1.5 GB of disk Space for Data file. To determine the amount of free disk space in MB on the system, use the following command :
[root@testdb ~]# df -m /u01/
Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/hda7                17439      3624     12915  22% /u01  

[root@testdb ~]# df -m /u02/
Filesystem           1M-blocks      Used Available Use% Mounted on
/dev/hda6                17439      1777     14763  11% /u02

[NB: /u01 is use for Oracle Software and /u01 is use for Oracle Database file]

4. Software Requirements Checking

Kernel Requirements

  • To determine whether the required kernel is installed, use the following command. A sample output displayed by running this command on a Oracle Enterprise Linux 5.0 system:
        [root@testdb ~]# uname –r

  • To determine whether the required packages are installed, use commands similar to the following:
        # rpm -qa | grep <package_name>

        [root@testdb ~]# rpm -qa | grep binutils
  • To Find the Packege in the CD-ROM(Oracle Entriprece Linux) use the Commands similer
        # ls -la /media/cdrecorder/Server | grep <package_name>
  • To install, use commands similar to the following:
        # rpm -ivh <package_name>

5. Configuring Kernel Parameters

[root@testdb ~]# sysctl -a | grep sem
kernel.sem = 250        32000   100     128

[root@testdb ~]# sysctl -a | grep shm
vm.hugetlb_shm_group = 0
kernel.shmmni = 4096
kernel.shmall = 268435456
kernel.shmmax = 4294967295

[root@testdb ~]# sysctl -a | grep file-max
fs.file-max = 6553600

[root@testdb ~]# sysctl -a | grep ip_local_port_range
net.ipv4.ip_local_port_range = 1024     65000

[root@testdb ~]# sysctl -a | grep rmem_
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304

[root@testdb ~]# sysctl -a | grep wmem_
net.core.wmem_default = 262144
net.core.wmem_max = 262144
vm.lowmem_reserve_ratio = 256   256     32
  • Using any text editor, create or edit the /etc/sysctl.conf file, and add or edit lines similar to the following:
kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range = 1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

·  Enter the following command to change the current values of the kernel parameters:
   [root@testdb ~]# /sbin/sysctl –p

 Review the output from this command to verify that the values are correct
 N.B: For Safety to make sure the change effect you may restart the system.
