Please provide me with the guidance to install oracle 11gr2 on Ubuntu 14.04.

Step 1: Download Oracle Database Express Edition.

Step 2: Instructions before install Oracle

  1. Copy the downloaded file and paste it in home directory.

  2. Unzip using the command:

  3. Install required packages using the command:

    sudo apt-get install alien libaio1 unixodbc
  4. Enter into the Disk1 folder using command:

    cd Disk1/
  5. Convert RPM package format to DEB package format (that is used by Ubuntu) using the command:

    sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm
  6. Create the required chkconfig script using the command:

    sudo pico /sbin/chkconfig

    The pico text editor is started and the commands are shown at the bottom of the screen. Now copy and paste the following into the file and save:

    # Oracle 11gR2 XE installer chkconfig hack for Ubuntu
    if [[ ! `tail -n1 $file | grep INIT` ]]; then
        echo >> $file
        echo '### BEGIN INIT INFO' >> $file
        echo '# Provides: OracleXE' >> $file
        echo '# Required-Start: $remote_fs $syslog' >> $file
        echo '# Required-Stop: $remote_fs $syslog' >> $file
        echo '# Default-Start: 2 3 4 5' >> $file
        echo '# Default-Stop: 0 1 6' >> $file
        echo '# Short-Description: Oracle 11g Express Edition' >> $file
        echo '### END INIT INFO' >> $file
    update-rc.d oracle-xe defaults 80 01
  7. Change the permission of the chkconfig file using the command:

    sudo chmod 755 /sbin/chkconfig  
  8. Set kernel parameters. Oracle 11gR2 XE requires additional kernel parameters which you need to set using the command:

    sudo pico /etc/sysctl.d/60-oracle.conf
  9. Copy the following into the file and save:

    # Oracle 11g XE kernel parameters 
    net.ipv4.ip_local_port_range=9000 65000  
    kernel.sem=250 32000 100 128 
  10. Verify the change using the command:

    sudo cat /etc/sysctl.d/60-oracle.conf 
  11. You should see what you entered earlier. Now load the kernel parameters:

    sudo service procps start
  12. Verify the new parameters are loaded using:

    sudo sysctl -q fs.file-max

    You should see the file-max value that you entered earlier.

  13. Set up /dev/shm mount point for Oracle. Create the following file using the command:

    sudo pico /etc/rc2.d/S01shm_load
  14. Copy the following into the file and save.

    case "$1" in
        mkdir /var/lock/subsys 2>/dev/null
        touch /var/lock/subsys/listener
        rm /dev/shm 2>/dev/null
        mkdir /dev/shm 2>/dev/null
        echo error
        exit 1
  15. Change the permissions of the file using the command:

    sudo chmod 755 /etc/rc2.d/S01shm_load
  16. Now execute the following commands:

    sudo ln -s /usr/bin/awk /bin/awk 
    sudo mkdir /var/lock/subsys 
    sudo touch /var/lock/subsys/listener

    Now, Reboot Your System

Step 3: Install Oracle

  1. Install the oracle DBMS using the command:

    sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb
  2. Configure Oracle using the command:

    sudo /etc/init.d/oracle-xe configure 
  3. Setup environment variables by editting your .bashrc file:

    pico ~/.bashrc
  4. Add the following lines to the end of the file:

    export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe
    export ORACLE_SID=XE
    export NLS_LANG=`$ORACLE_HOME/bin/`
    export ORACLE_BASE=/u01/app/oracle
    export PATH=$ORACLE_HOME/bin:$PATH
  5. Load the changes by executing your profile:

    . ~/.bashrc
  6. Start the Oracle 11gR2 XE:

    sudo service oracle-xe start
  7. Add user YOURUSERNAME to group dba using the command:

    sudo usermod -a -G dba YOURUSERNAME

Step 4: Using the Oracle XE Command Shell

  1. Start the Oracle XE 11gR2 server using the command:

    sudo service oracle-xe start
  2. Start command line shell as the system admin using the command:

    sqlplus sys as sysdba

    Enter the password that you gave while configuring Oracle earlier. You will now be placed in a SQL environment that only understands SQL commands.

  3. Create a regular user account in Oracle using the SQL command:

    create user USERNAME identified by PASSWORD;

    Replace USERNAME and PASSWORD with the username and password of your choice. Please remember this username and password. If you had error executing the above with a message about resetlogs, then execute the following SQL command and try again:

    alter database open resetlogs;
  4. Grant privileges to the user account using the SQL command:

    grant connect, resource to USERNAME;

    Replace USERNAME and PASSWORD with the username and password of your choice. Please remember this username and password.

  5. Exit the sys admin shell using the SQL command:

  6. Start the commandline shell as a regular user using the command:


    Now, you can run sql commands...

  • At step 6 I am getting Starting Oracle Net Listener...touch: cannot touch '/var/lock/subsys/listener': No such file or directory Done Configuring database... Database Configuration failed. Look into /u01/app/oracle/product/11.2.0/xe/config/log for details – Skynet May 5 '16 at 13:39

    @Skynet. I got the same error. Although i don't able to understand these commands, i tried and able to configure oracle XE or linux mint. – Jeet Jul 5 '16 at 7:45
  • @Skynet. And also tried this link. Search content Reference in the comment after expand : to get it to work I needed to add the following lines in the beginning of the file "/etc/init.d/oracle-xe"...between steps 6(i) and 6(ii) if [ -L /dev/shm ]; then rm -rf /dev/shm mkdir /dev/shm mount -t tmpfs shmfs -o size=2048m /dev/shm fi if [ ! -d /var/lock/subsys ]; then mkdir /var/lock/subsys touch /var/lock/subsys/listener fi – Jeet Jul 5 '16 at 8:08

    /etc/rc2.d/S01shm_load seems missing ;; indicating the end of an alternative at line 7. – user3523935 Nov 4 '16 at 8:18

    Had to use sudo service procps restart instead of sudo service procps start – ossbuntu Oct 24 '17 at 11:53

Thank you for the detailed tutorial but I was getting error

touch: cannot touch '/var/lock/subsys/listener' .. 

in the step sudo /etc/init.d/oracle-xe configure. So as suggested on I added the following lines in /etc/init.d/oracle-xe

if [ -L /dev/shm ]; then
    rm -rf /dev/shm
    mkdir /dev/shm
    mount -t tmpfs shmfs -o size=2048m /dev/shm

if [ ! -d /var/lock/subsys ]; then
 mkdir /var/lock/subsys
 touch /var/lock/subsys/listener

...and its working fine for me

  • You get the error because there's an error in the script /etc/rc2.d/S01shm_load in Saikat's answer. Fixing this would be a cleaner solution. I'll edit the answer with the correct script. – Forage Sep 29 '17 at 8:32
  • Forget it, reviewers are idiots. After the first and and second attempt to correct the script have failed I give up. Apparently it's more important to mindlessly vote to score points then to actually try to understand what is being done. – Forage Oct 2 '17 at 15:11

This worked fine, however I got the following error:

sudo /etc/init.d/oracle-xe start
[....] Starting oracle-xe (via systemctl): oracle-xe.serviceJob for oracle-xe.service failed because the control process exited with error code. See "systemctl status oracle-xe.service" and "journalctl -xe" for details.

Looking into it:

systemctl status oracle-xe.service
Jan 27 10:01:05 <myusername> su[29699]: No passwd entry for user 'oracle'

I resolved it by simply adding a user:

sudo adduser oracle

Hope this helps someone.
