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

Download the following software.

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

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 /

eject

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
