How to Install and Getting Started on Oracle 11g R2 Database for Linux Ubuntu 12.04 Precise 32bit Easy Visual-Guide

April 11, 2013 | By Duchateaux.

Installing Oracle 11g Database for Ubuntu 12.04 Precise 32bit

This an Easy and Step-by-Step Guide to Install the Oracle 11g R2 Database on Ubuntu Linux 12.04 Precise Pangolin i386 Desktop.

Especially relevant: Ubuntu-like Systems are Not in the List of Oracle 11g Database Supported OS So you should Be Careful and Use it at most for Development and Not As Production Database Server!

The Guide Includes All the Essentials Commands and Basic Screenshots of the Installation Process.

The Process is somewhat Extended and Advanced so it Demand some Basic Command Line Confidence.

Now Relax and Take the Time of Reading, Understanding and Executing Carefully the Instructions Contained here.

Metallic Oracle

  1. Download the Oracle 11g R2 Database:

    The Link Contains the List of Oracle 11g r2 Database Releases.

  2. Open Terminal Window
    (Press “Enter” to Execute Commands)

    Ubuntu Linux Open Terminal

    In case first see: Terminal QuickStart Guide.

  3. Login as Root User 

    sudo su

    If Got “User is Not in Sudoers file” then see: How to Enable sudo

  4. Make Network Configuration

    • Get hostname: 

      hostname

    • Get IP: 

      /sbin/ifconfig

      You will Find It Under the lo >> inet Section.

    • Check if Hostname is Already into the Enabled Hosts File.

      cat /etc/hosts

      If It’s Not Present then Insert it with:

      nano /etc/hosts

      Insert:

      [myIP] [myHostname]

      Example: ‘127.0.0.1 localhost.localdomain’

      Ctrl+Shift+v to Paste Content on nano
      Ctrl+x to Save and Exit       from nano Editor :)

    • Grant Connection to X Server

      xhost +myIP

      Example: # xhost +127.0.0.1

  5. Install Prerequisite Packages

    apt-get install alien autoconf automake autotools-dev binutils 
doxygen elfutils expat gawk gcc gcc-multilib g++-multilib ia32-libs 
ksh less libtiff4 libtiff4-dev lib32z1 libaio1 libaio-dev libc6-dev libc6-dev-i386 libc6-i386 
libelf-dev libltdl-dev libmotif4 libodbcinstq4-1 libodbcinstq4-1:i386 libpth-dev 
libpthread-stubs0 libpthread-stubs0-dev libstdc++5 lsb-cxx make openssh-server 
pdksh rlwrap rpm sysstat unixodbc unixodbc-dev x11-utils zlibc

  6. Make Symlinks to Binaries and Libraries

    Linking Binaries

    ln -s /usr/bin/awk /bin/awk
    ln -s /usr/bin/rpm /bin/rpm
    ln -s /usr/bin/basename /bin/basename

    Linking Libraries

    ln -s /usr/lib/x86_64-linux-gnu /usr/lib64
    cd /lib64
    sudo ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1 . 

  7. Add Groups and User

    groupadd -g 502 oinstall
    groupadd -g 503 dba
    groupadd -g 504 oper
    groupadd -g 505 asmadmin
    useradd -u 502 -g oinstall -G dba,asmadmin,oper -s /bin/bash -m oracle
    passwd oracle

    Take Note of the oracle User Pass :)

  8. Make Target Directories 

    mkdir -p /u01/app/oracle/product/11.2.0/
    chown -R oracle:oinstall /u01
    chmod -R 775 /u01

  9. Parameters Configuration SetUp

    • Edit /etc/sysctl.conf file.

      nano /etc/sysctl.conf

      Then hit Ctrl+x to Save and Exit from nano Editor
      Add or amend the following lines 

      #### Oracle 11g Kernel Parameters ####
fs.suid_dumpable = 1
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 818227
kernel.shmmax = 4189323264
kernel.shmmni = 4096
kernel.panic_on_oops = 1
# semaphores: semmsl, semmns, semopm, semmni
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=1048576

      The Values of ‘shmall’ and ‘shmmax’ Need to be Customized following your System Memory Size.
      Here above is a Valid Setup for a 8Gb RAM Size!
      If you need to Change first Check your Phisical Memory Size with:

      cat /proc/meminfo | grep MemTotal

      Then ‘shmall’ should be Set as:

      [RamKb] / 10

      And instead ‘shmmax’ as:

      [RamKb] * 1024 / 2

      For further Instructions See Oracle Documentation…

      Comment out these lines below that Gives an Error

      #net.bridge.bridge-nf-call-ip6tables = 0
      
#net.bridge.bridge-nf-call-iptables = 0
      
#net.bridge.bridge-nf-call-arptables = 0

    • Edit /etc/security/limits.conf file.

      nano /etc/security/limits.conf

      Add the following lines 

      #### oracle User Settings 4 Oracle 11g ####/noracle       soft  nproc  2047/noracle       hard  nproc  16384/noracle       soft  nofile 1024/noracle       hard  nofile 65536/noracle       soft  stack  10240

    • Load the New Kernel Parameters

      /sbin/sysctl -p

  10. Unzip, Set oracle as Owner and Relocate database

    cd </path/2>
    unzip linux_11gR2_database_1of2.zip
    unzip linux_11gR2_database_2of2.zip
    chown -R oracle:oinstall database
    mv database /tmp

  11. Add Paths to oracle’s .bashrc

    Login as Oracle 

    su oracle

    Edit .bashrc file 

    nano ~/.bashrc

    Insert:

    # Oracle Settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR
ORACLE_HOSTNAME=[HOSTNAME]; export ORACLE_HOSTNAME
ORACLE_UNQNAME=DB11G; export ORACLE_UNQNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/dbhome_1; export ORACLE_HOME
ORACLE_SID=[DBSID]; 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:/usr/lib64; export LD_LIBRARY_PATH
CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; export CLASSPATH

    Replace [HOSTNAME] with IP and [DBSID] with SID Name

    In this Example Respectively:

    • HOSTNAME = 127.0.0.1

    • DBSID = SID

    Load New .bashrc Settings

    bash

  12. Install the Oracle 11g Software

    cd /tmp/database
    chmod -R +x /tmp/database
    ./runInstaller

    If you Get: “Check if the DISPLAY variable is set. Failed”. Look Link Below.
