Installing Java, Oracle 11g R2 Express Edition and SQL Developer on Ubuntu 64-bit

by Mike Heeren on March 18, 2014 · 11 comments

A while ago I tried to install Oracle 11g R2 Express Edition on a 64-bit Ubuntu machine. This proved to be not as easy as you would expect. There are many blogs and articles about this subject and I tried a number of them. Unfortunately neither of the instructions seemed to work completely on my machine. With the combined information from the authors, I finally got it to work and I’ll gladly share my recipe in this blog. I have also included the installation steps for SQL Developer en Java (which is needed to install SQL Developer) in this blog. The installation was performed on a Ubuntu 12.04 VM with the following software.

Installing Java

We start with installing Java on the machine. My personal preference is to use Oracle Java JDK. Installing this JDK could be done easily by performing the following statements.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

The screen in figure 1 will appear in the terminal, hit enter to proceed. After this, the screen in figure 2 will be shown. Navigate to <Yes> using the left arrow on your keyboard and hit enter. Oracle JDK 7 will be installed.

To validate the Java installation, execute the following command:

java -version

This should result in the following (or something similar).

java version “1.7.0_51”
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

The next next step is to set the JAVA_HOME environment variable. To do this, open the /etc/bash.bashrc file by executing the following statement.

sudo gedit /etc/bash.bashrc

Scroll to the bottom of the file and add the following lines.

export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export PATH=$JAVA_HOME/bin:$PATH

Save the file and close the editor. To load the changes, execute the following statement.

source /etc/bash.bashrc

To validate the changes you can execute the following statement.

echo $JAVA_HOME

The result of this statement should be the following.

/usr/lib/jvm/java-7-oracle

Installing Oracle 11g R2 Express Edition

For the installation of Oracle 11g R2 Express Edition (XE), a couple of additional Linux packages are required. These packages can be installed by executing the following statement.

sudo apt-get install alien libaio1 unixodbc

The next step is to download the Oracle 11g R2 Express Edition from the Oracle website. Make sure you select the Linux x64 version from http://www.oracle.com/technetwork/products/express-edition/downloads/index.html. After the download is completed, open the terminal and navigate to the download directory. In my case this can be done by executing the following statement.

cd Downloads

The next step step is to unzip the downloaded file. To do this, execute the following command.

unzip oracle-xe-11.2.0-1.0.x86_64.rpm.zip

A new directory (Disk1) is added to the Download directory. Navigate to this directory:

cd Disk1

Now we have to convert the Red Hat package (rpm) to a Debian package. This may be done using the alien command. The -d parameter is used to inform alien that a Debian package should be generated. When the -scripts parameter is toggled, alien will try to convert the scripts that are meant to be run when the package is installed and removed.

sudo alien --scripts -d oracle-xe-11.2.0-1.0.x86_64.rpm

This step may take a while, while this statement is executing we can do the following steps. Open a new terminal window for these steps.

The Red Hat package, relies on the /sbin/chkconfig file, which is not used in Ubuntu. To successfully install Oracle XE we use a simple trick. Start by creating a custom /sbin/chkconfig file by executing the following statement.

sudo gedit /sbin/chkconfig

Copy and paste the following into the editor:

#!/bin/bash
# Oracle 11gR2 XE installer chkconfig hack for Ubuntu
file=/etc/init.d/oracle-xe
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
fi
update-rc.d oracle-xe defaults 80 01
#EOF

Save the file and close the editor. Now we have to provide the file with the appropriate execution privileges.

sudo chmod 755 /sbin/chkconfig

After this, we have to create the file /etc/sysctl.d/60-oracle.conf to set the additional kernel parameters. Open the file by executing the following statement.

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

Copy and paste the following into the file. Kernel.shmmax is the maximum possible value of physical RAM in bytes. 536870912 / 1024 /1024 = 512 MB.

# Oracle 11g XE kernel parameters
fs.file-max=6815744
net.ipv4.ip_local_port_range=9000 65000
kernel.sem=250 32000 100 128
kernel.shmmax=536870912

Save the file. The changes in this file may be verified by executing:

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

Load the kernel parameters:

sudo service procps start

The changes may be verified again by executing:

sudo sysctl -q fs.file-max

This method should return the following:

fs.file-max = 6815744

After this, execute the following statements to make some more required changes:

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

Close the second terminal window and return to the first terminal window. The rpm package should be converted and a new file called oracle-xe-11.2.0-2_amd64.deb have been generated. To run this file, execute the following command:

sudo dpkg --install oracle-xe_11.2.0-2_amd64.deb

Execute the following to avoid getting a ORA-00845: MEMORY_TARGET error. Note: replace “size=4096m” with the size of your (virtual) machine’s RAM in MBs.

sudo rm -rf /dev/shm
sudo mkdir /dev/shm
sudo mount -t tmpfs shmfs -o size=4096m /dev/shm

Create the file /etc/rc2.d/S01shm_load.

sudo gedit /etc/rc2.d/S01shm_load

Copy and paste the following in the file. Note: replace “size=4096m” with the size of your machine’s RAM in MBs.

#!/bin/sh
case "$1" in
start) mkdir /var/lock/subsys 2>/dev/null
touch /var/lock/subsys/listener
rm /dev/shm 2>/dev/null
mkdir /dev/shm 2>/dev/null
mount -t tmpfs shmfs -o size=4096m /dev/shm ;;
*) echo error
exit 1 ;;
esac

Save the file, close the editor and provide the appropriate execution privileges.

sudo chmod 755 /etc/rc2.d/S01shm_load

Configuring Oracle 11g R2 Express Edition

If you have successfully installed to Oracle 11g R2 Express Edition server, it’s time to configure the server. To start the configuration of the server, execute the following command and follow the “wizard” in the terminal. Default values are shown between brackets for each question.

sudo /etc/init.d/oracle-xe configure

Now it is time to set-up some environmental variables. Open the /etc/bash.bashrc file by executing the following statement:

sudo gedit /etc/bash.bashrc

Scroll to the bottom of the file and add the following lines.

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/xe
export ORACLE_SID=XE
export NLS_LANG=`$ORACLE_HOME/bin/nls_lang.sh`
export ORACLE_BASE=/u01/app/oracle
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
export PATH=$ORACLE_HOME/bin:$PATH

Save the file and close the editor. To load the changes, execute the following statement:

source /etc/bash.bashrc

To validate the changes you can execute the following statement.

echo $ORACLE_HOME

This statement should result in the following output.

/u01/app/oracle/product/11.2.0/xe

After this step it is recommended to reboot the machine. After the reboot is completed, you should be able to start the Oracle server using the following command:

sudo service oracle-xe start

A file named oraclexe-gettingstarted.desktop is placed on your desktop. To make this file executable, navigate to you desktop.

cd ~/Desktop

To make the file executable, execute the following statement.

sudo chmod a+x oraclexe-gettingstarted.desktop

Installing SQL Developer

Finally, after the installation of Oracle 11g R2 Express Edition and Java, SQL Developer could be installed. This is done by performing the following steps.

Download Oracle SQL Developer from the Oracle site. Select the Linux RPM package: http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html. Open a terminal window and navigate to the Download directory:

cd Downloads

Convert the Red Hat package to a Ubuntu package. Note: this may take a while.

sudo alien --scripts -d sqldeveloper-4.0.0.13.80-1.noarch.rpm

A file named sqldeveloper_4.0.0.13.80-2_all.deb will be generated. To run this file, execute the following statement:

sudo dpkg --install sqldeveloper_4.0.0.13.80-2_all.deb

Create a .sqldeveloper directory in your home folder:

sudo mkdir /home/.sqldeveloper/

Run SQL Developer from the terminal.

sudo /opt/sqldeveloper/sqldeveloper.sh

Now enter the full Java path. In my case this is done as follows:

/usr/lib/jvm/java-7-oracle

These steps worked for me to install Oracle XE and SQL Developer on Ubuntu 64-bit, and have been validated by one of my colleagues. I am curious to know if it worked for you. Please also let me know if you find any mistakes or have any additions to make this script better.

Good luck!

  2. Excellent walkthrough! I was able to install Oracle on Ubuntu 14.04 with ease. The only change was when to invoke `oracle-xe configure`. It failed at first, so I updated bash.bashrc, rebooted then invoked `oracle-xe configure` and it started fine. Thank you for this walkthrough!

    Why don’t you have this whole process as a wget and bash script?

    It’s nice to see the steps, but much nicer to clickety click.
