How to install Oracle 11g XE on Ubuntu

Ubuntu is not a Linux distribution officially supported by Oracle.

Oracle Database XE Requirements: Operating system
  • Oracle Enterprise Linux 4 Update 7
  • Oracle Enterprise Linux 5 Update 2
  • Red Hat Enterprise Linux 4 Update 7
  • Red Hat Enterprise Linux 5 Update 2
  • SUSE Linux Enterprise Server 10 SP2
  • SUSE Linux Enterprise Server 11

You can install Oracle 11g XE on Ubuntu with a few tricks.

Visit For 64-bit systems, choose Oracle Database Express Edition 11g Release 2 for Linux x64. You need to log in to download the file. --Sign up if you are not a member of the Oracle website-- When you log in to the site, the download begins. After downloading, go to the directory where the file exists and execute the following command.

sudo apt install alien libaio1 unixodbc
cd Disk1
sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm

Create a /sbin/chkconfig file.

sudo nano /sbin/chkconfig

Copy and Paste the following into the file.

# 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

Save the above file and provide appropriate execute privilege.

sudo chmod 755 /sbin/chkconfig

Set the Kernel parameters.

sudo nano /etc/sysctl.d/60-oracle.conf

Copy the following. Paste it into the file.

# Oracle 11g XE kernel parameters  
net.ipv4.ip_local_port_range=9000 65000  
kernel.sem=250 32000 100 128 

Check the swap memory.

free -m
total       used       free     shared    buffers     cached
Mem:          3942       3809        133        947         50       1571
-/+ buffers/cache:       2186       1756
Swap:         4083        378       3705

Unlike the above, if Swap doesn't exceed 4000, do the following.

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

Verify the kernel parameters.

sudo cat /etc/sysctl.d/60-oracle.conf

Load kernel parameters.

sudo service procps restart

(In my case, it came out differently from the set value, but I was able to complete the installation)

sudo sysctl -q fs.file-max

Go to the Disk1 directory and run the following commands:

sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb
sudo /etc/init.d/oracle-xe configure

Installing the Oracle JDBC driver in local repository

The Maven repository does not provide the Oracle JDBC driver. Therefore, you need to install the Oracle JDBC driver in your local repository and set the dependency on pom.xml.

Run the following.

cd /u01/app/oracle/product/11.2.0/xe/jdbc/lib

mvn install:install-file \
-Dfile=ojdbc6.jar \ \
-DartifactId=ojdbc6 \
-Dversion= \

The following shows how to add Oracle JDBC driver to pom.xml according to the information stored in the local repository.
