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.
The next step step is to unzip the downloaded file. To do this, execute the following command.
A new directory (Disk1) is added to the Download directory. Navigate to this directory:
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 unzip 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:
To validate the changes you can execute the following statement.
This statement should result in the following output.
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.
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:
Convert the Red Hat package to a Ubuntu package. Note: this may take a while.
sudo alien --scripts -d sqldeveloper-18.104.22.168.78-1.noarch.rpm
A file named sqldeveloper_22.214.171.124.78-2_all.deb will be generated. To run this file, execute the following statement:
sudo dpkg --install sqldeveloper_126.96.36.199.78-2_all.deb
Create a .sqldeveloper directory in your home folder:
sudo mkdir /home/.sqldeveloper/
Run SQL Developer from the terminal.
Now enter the full Java path. In my case this is done as follows:
After that,follow instruction’s from this video……
Note: I just gathered several site’s information to install Oracle 11g R2 Express Edition (XE).
