How to Install Oracle 12c on Ubuntu 15.04

This tutorial show How to Install Oracle 12C on Ubuntu 15.04. Ubuntu like systems are not in the list of Oracle 12c Database Supported OS, so you should be careful and use it at most for Development and not as Production Database Server

Following is the summarized steps of How to Install Oracle 12c on Ubuntu 15.04
  1. Oracle Installation Prerequisites
  2. Install Oracle 12c on Ubuntu
  3. Post Installation
Detailed Step by Step of How to Install Oracle 12c on Ubuntu 15.04

1. Oracle Installation Prerequisites

Host file modification
The /etc/hosts file must contain a fully qualified name for the server.
IP-address  fully-qualified-machine-name machine-name

2. Hardware requirement

  1. General Server Minimum Requirements
    Server should be started in runlevel 3 or runlevel 5.
    Server display cards provide at least 1024 x 768 display resolution.
  2. Disk Space Requirements on Linux x86-64
    Disk Space for Enterprise Edition Installation type is 6.4 GB
    1 GB of space in the /tmp directory on your Linux system.
  3. Server Memory Minimum Requirements
    Ensure that your system meets the following memory requirements:
    Minimum: 1 GB of RAM
    Recommended: 2 GB of RAM or moreSwap Space Requirement for Linux
    1. If RAM size is between 1 GB to 2 GB then Swap space should be 1.5 times of the RAM
    2. If RAM size is between 2 GB to 16 GB then Swap space should be equal to the size of the RAM
    3. If RAM size is more than 16 GB then Swap space should be 16 GB

3. Install Prerequisites packages

  1. Open a command prompt by pressing CTRL + ALT + t and run following command as a root / root equivalent user to downloads the package lists from the repositories and updates them to get information on the newest versions of packages and their dependencies. It will do this for all repositories and PPAs.
    sudo apt-get update
  2. Run following command to handle changing dependencies with new versions of packages.
    sudo apt-get dist-upgrade
  3. Restart machine by running following command
    sudo reboot --reboot
  4. Again run dist-upgrade to check if there is any new versions of packages
    sudo apt-get dist-upgrade
  5. Run following command to install dependencies
    sudo apt-get -y install alien binutils build-essential \
    cpp-4.4 debhelper g++-4.4 gawk gcc-4.4 gcc-4.4-base \
    gettext html2text lib32z1 lib32ncurses5 intltool-debian \
    ksh lib32z1-dev libaio-dev libaio1 libbeecrypt7 libc6 \
    libc6-dev libc6-dev-i386 libelf-dev libelf1 libltdl-dev \
    libltdl7 libmotif4 libodbcinstq4-1 libodbcinstq4-1:i386 \
    libqt4-core libqt4-gui libsqlite3-0 libstdc++5 libstdc++6 \
    libstdc++6-4.4-dev lsb lsb-core lsb-cxx lsb-desktop \
    lsb-graphics make odbcinst pax po-debconf rpm \
    rpm-common sysstat unixodbc unixodbc-dev unzip

4. Creating Required Operating System Groups and Users

  1. Run following command as root/ root equivalent user to create required Operating System groups and users
    sudo addgroup oinstall
    sudo addgroup dba
    sudo addgroup nobody
    sudo usermod -g nobody nobody
    sudo useradd -g oinstall -G dba -p password -d /home/oracle -s /bin/bash oracle
    sudo mkdir /home/oracle
    sudo chown -R oracle:dba /home/oracle
    sudo mkdir -p /u01/app/oracle
    sudo mkdir -p /u01/binaries
    sudo chown -R oracle:dba /u01
  2. Set the password for the oracle user which we have created for installation purpose
    sudo passwd oracle

5. Configuring Kernel Parameters and Resource Limits

  1. Make ourself as Red Hat by running following command as root/ root equivalent user
    echo 'Red Hat Linux release 6' | sudo tee -a /etc/redhat-release
    
  2. We need to create some soft links to start the installation. To do so run the following commands as root/ root equivalent user,
    sudo mkdir /usr/lib64
    sudo ln -s /etc /etc/rc.d
    sudo ln -s /lib/x86_64-linux-gnu/libgcc_s.so.1 /lib64/
    sudo ln -s /usr/bin/awk /bin/awk
    sudo ln -s /usr/bin/basename /bin/basename
    sudo ln -s /usr/bin/rpm /bin/rpm
    sudo ln -s /usr/lib/x86_64-linux-gnu/libc_nonshared.a /usr/lib64/
    sudo ln -s /usr/lib/x86_64-linux-gnu/libpthread_nonshared.a /usr/lib64/
    sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /lib64/
    sudo ln -s /usr/lib/x86_64-linux-gnu/libstdc++.so.6 /usr/lib64/
  3. To change the shell configuration for oracle user run following commands as root/ root equivalent user
    sudo cp /etc/security/limits.conf /etc/security/limits.conf.original
    echo "#Oracle 12C shell limits:" | sudo tee -a /etc/security/limits.conf
    echo "oracle soft nproc 2048" | sudo tee -a /etc/security/limits.conf
    echo "oracle hard nproc 16384"| sudo tee -a /etc/security/limits.conf
    echo "oracle soft nofile 1024" | sudo tee -a /etc/security/limits.conf
    echo "oracle hard nofile 65536" | sudo tee -a /etc/security/limits.conf
  4. Run following command to change the kernel parameters as root/ root equivalent user.
    echo "#" | sudo tee -a /etc/sysctl.conf
    echo "# Oracle 12C entries" | sudo tee -a /etc/sysctl.conf
    echo "fs.aio-max-nr=1048576" | sudo tee -a /etc/sysctl.conf
    echo "fs.file-max=6815744" | sudo tee -a /etc/sysctl.conf
    echo "kernel.shmall=2097152" | sudo tee -a /etc/sysctl.conf
    echo "kernel.shmmni=4096" | sudo tee -a /etc/sysctl.conf
    echo "kernel.sem=250 32000 100 128" | sudo tee -a /etc/sysctl.conf
    echo "net.ipv4.ip_local_port_range=9000 65500" | sudo tee -a /etc/sysctl.conf
    echo "net.core.rmem_default=262144" | sudo tee -a /etc/sysctl.conf
    echo "net.core.rmem_max=4194304" | sudo tee -a /etc/sysctl.conf
    echo "net.core.wmem_default=262144" | sudo tee -a /etc/sysctl.conf
    echo "net.core.wmem_max=1048586" | sudo tee -a /etc/sysctl.conf
    echo "kernel.shmmax=1073741824" | sudo tee -a /etc/sysctl.conf

    Note: kernel.shmmax = max possible value, e.g. size of physical memory in bytes. In my case machine is having 2GB so we are specifying 1GB. Adjust the parameter as per your configuration
  5. Load new kernel parameters, by running following as root/ root equivalent user.
    sudo sysctl -p
  6. We need to do changes in start-up script, run following commands as root/ root equivalent user
    for i in 0 1 2 3 4 5 6 S
    do sudo ln -s /etc/rc$i.d /etc/rc.d/rc$i.d
    done

6. Downloading Software

Login as a oracle user as we are going to install database using oracle user.
Go to following link to download Oracle 12c.
Download Oracle 12c Enterprise Edition
Check Accept License Agreement radio button and Download 2 files.

Download the file to /u01/binaries.





7. Unpack Files

Login as a oracle user and open a terminal by pressing CTRL + ALT + T
Go to /u01/binaries folder using following command
cd /u01/binaries

Run following commands to extract binaries


unzip linuxamd64_12102_database_1of2.zip
unzip linuxamd64_12102_database_2of2.zip
Before doing the installation we need to give proper permission to the extracted file, to do the same run following command

chown -Rf oracle:dba /u01/binaries

Install Oracle 12c on Ubuntu

  1. Login as a oracle user and start installation using following command
    cd /u01/binaries/database
    /u01/binaries/database/runInstaller -ignoreSysPrereqs
  2. In the Configure Security Updates unchecked I wish to receive security updates via My Oracle Support and Click Next I have skipped Oracle Support Password provision as I don’t want to receive updates.
