Oracle Database 11g Release 2 (11.2) Installation On Oracle Linux 6
This article describes the installation of Oracle Database 11g Release 2 (11.2) (64-bit) on Oracle Linux 5 (64-bit). The article is based on a server installation with a minimum of 2G swap, secure Linux disabled. Oracle recommend a default server installation, but for these installations the following package groups installed:
- GNOME Desktop Environment
- Editors
- Graphical Internet
- Text-based Internet
- Development Libraries
- Development Tools
- Server Configuration Tools
- Administration Tools
- Base
- System Tools
- X Window System
An example of this type of Linux installations can be seen here. Alternative installations may require more packages to be loaded, in addition to the ones listed below.
- Download Software
- Unpack Files
- Hosts File
- Oracle-Validated Setup
- Manual Setup
- Additional Setup

- Post Installation
Download Software
Download the following software.
Download the Oracle software from OTN or MOS depending on your support status.
- OTN: Oracle Database 11g Release 2 (11.2.0.1) Software (64-bit)
- MOS: Oracle Database 11g Release 2 (11.2.0.2 or 11.2.0.3) Software (64-bit)
Unpack Files
Unzip the files.
# 11.2.0.1
unzip linux.x64_11gR2_database_1of2.zip
unzip linux.x64_11gR2_database_2of2.zip
#11.2.0.2
unzip p10098816_112020_Linux-x86-64_1of7.zip
unzip p10098816_112020_Linux-x86-64_2of7.zip
#11.2.0.3
unzip p10404530_112030_Linux-x86-64_1of7.zip
unzip p10404530_112030_Linux-x86-64_2of7.zip
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.
<IP-address> <fully-qualified-machine-name> <machine-name>
For example.
127.0.0.1 localhost.localdomain localhost
192.168.2.181 ol5-11gr2.localdomain ol5-11gr2
Oracle-Validated Setup
If you plan to use the "oracle-validated" package to perform all your prerequisite setup, follow the instructions at http://public-yum.oracle.com to setup the yum repository for OL, then perform the following command.
# yum install oracle-validated
All necessary prerequisites will be performed automatically.
Manual Setup
If you have not used the "oracle-validated" package to perform all prerequisites, you will need to manually perform the following setup tasks.
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 <param-name>
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
net.core.rmem_default=4194304
net.core.rmem_max=4194304
net.core.wmem_default=262144
net.core.wmem_max=1048586
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.

cd /

Create the new groups and users.
groupadd oinstall
groupadd dba
groupadd oper
groupadd asmadmin
useradd -g oinstall -G dba,oper,asmadmin oracle
passwd oracle
Note. We are not going to use the "asmadmin" group, since this installation will not use ASM.
AdditionalSetup
The following setup tasks must be performed regardless of which setup method you used previously.
Disable secure linux by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
SELINUX=disabled
Alternatively, this alteration can be done using the GUI tool (Applications > System Settings > Security Level). Click on the SELinux tab and disable the feature. If SELinux is disabled after installation, the server will need a reboot for the change to take effect.
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 +<machine-name>
Login as the oracle user and add the following lines at the end of the ".bash_profile" file, remembering to adjust them for your specific installation.
# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=ol5-112.localdomain; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
PATH=/usr/sbin:$PATH; export PATH
PATH=$ORACLE_HOME/bin:$PATH; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH
Installation
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=<machine-name>:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
./runInstaller
Proceed with the installation of your choice. You can see the type of installation I performed by clicking on the links below to see screen shots of each stage.
Post Installation
Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
DB11G:/u01/app/oracle/product/11.2.0/db_1:Y
