Oracle Database 11g Release 1 (11.1) Installation On Fedora 8 (F8)

This article describes the installation of Oracle Database 11g Release 1 (11.1) on Fedora 8 (F8). The article is based on a server installation with a minimum of 2G swap, secure Linux disabled and the following package groups installed:

• GNOME Desktop Environment
• Editors
• Graphical Internet
• Development Libraries
• Development Tools
• Server Configuration Tools
• Administration Tools
• Base
• Fonts
• Legacy Fonts
• Hardware Support
• System Tools
• X Window System

An example of this type of Linux installation 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
• Set Kernel Parameters
• Setup
• Installation
• Post Installation

Download Software

Download the following software:

• Oracle Database 11g Release 1 (11.1) Software

Unpack Files

Unzip the files:

unzip linux_11gR1_database.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></machine-name></fully-qualified-machine-name></ip-address>

Set Kernel Parameters

Oracle recommend the following minimum parameter settings:

kernel.shmall = 2097152
kernel.shmmax = 2147483648 # Smallest of -> (Half the size of the physical memory) or (4GB - 1 byte)
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
fs.file-max = 65536 # 512 * PROCESSES
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

The current values can be tested using the following command:

/sbin/sysctl -a | grep <param-name></param-name>

For Fedora 8, the following lines should be appended to the "/etc/sysctl.conf" file.

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
# semaphores: semmsl, semmns, semopm, semmni
kernel.sem = 250 32000 100 128
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

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  1024
oracle              hard    nofile  65536

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

session    required     /lib/security/pam_limits.so
session    required     pam_limits.so

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 (System > Administration > Firewall and SELinux). Click on the SELinux tab and disable the feature.

Setup

Install the following packages:

# From Fedora 8 DVD
cd /media/cdrom/Packages
rpm -Uvh binutils-2.*
rpm -Uvh elfutils-libelf-0.*
rpm -Uvh glibc-2.*
rpm -Uvh glibc-common-2.*
rpm -Uvh libgcc-4.*
rpm -Uvh libstdc++-4.*
rpm -Uvh make-3.*
rpm -Uvh elfutils-libelf-devel-0.*
rpm -Uvh glibc-devel-2.*
rpm -Uvh gcc-4.*
rpm -Uvh gcc-c++-4.*
rpm -Uvh libstdc++-devel-4.*
rpm -Uvh unixODBC-2.*
cd /
eject

# Not available on Fedora 8 DVD, but available from standard yum repository.
yum install libaio libaio-devel
yum install unixODBC-devel
yum install sysstat
yum install compat-libstdc++

# Required to mask Java conflict (thanks to Robert W. Benton for pointing this out)
yum --enablerepo=development install libxcb.i386

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 th "asmadmin" group, since this installation will not use ASM.

Create the directories in which the Oracle software will be installed:

mkdir -p /u01/app/oracle/product/11.1.0/db_1
chown -R oracle:oinstall /u01
chmod -R 775 /u01

Login as root and issue the following command:

xhost +<machine-name></machine-name>

Edit the /etc/redhat-release file replacing the current release information (Fedora release 8 (Werewolf)) with the following:

redhat release 5

Login as the oracle user and add the following lines at the end of the .bash_profile file:

# Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

ORACLE_HOSTNAME=f8.localdomain; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.1.0/db_1; export ORACLE_HOME
ORACLE_SID=DB11G; export ORACLE_SID
ORACLE_TERM=xterm; export ORACLE_TERM
PATH=/usr/sbin:$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/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

if [ $USER = "oracle" ]; then
  if [ $SHELL = "/bin/ksh" ]; then
    ulimit -p 16384
    ulimit -n 65536
  else
    ulimit -u 16384 -n 65536
  fi
fi

# Required to mask Java conflict (thanks to Robert W. Benton for pointing this out)
LIBXCB_ALLOW_SLOPPY_LOCK=true; export LIBXCB_ALLOW_SLOPPY_LOCK

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</machine-name>

Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory:

./runInstaller

During the installation enter the appropriate ORACLE_HOME and name then continue installation. Some of the prerequisite checks will not complete due to this not being a supported Linux distribution. Check each of these prerequisites to set them to "User Verified" then you can proceed.

Post Installation

Edit the /etc/redhat-release file restoring the original release information:

Fedora release 8 (Werewolf)

Edit the /etc/oratab file setting the restart flag for each instance to 'Y':

DB11G:/u01/app/oracle/product/11.1.0/db_1:Y
