Oracle XE On Ubuntu

ORACLE XE 10g for Linux

Hello Everyone :)

In this tutorial, I'm going to show you guys how to install Oracle XE (Express Edition) 10g on a Linux system.

for this tutorial, we will use as a Linux system Ubuntu on it's latest version 12.0. you can guys download it from here.

Oracle Express Edition Database is lightweight Database made for the development environment. Oracle XE is a great tool for developing POC (proof of concept) kind of applications. it comes with some dummy data that can be used by developers and save for them a lot of time setting the Db Environment.

This tutorial will guide you through the installation and the configuration steps so you can have a set and ready to use environment.

I #  INSTALLATION

First, we need to download and install the following packages. 

                                 1 -> oracle-xe-universal_10.2.0.1-1.1_i386.deb  

                                 2 -> oracle-xe-client_10.2.0.1-1.2_i386.deb

use the command dpkg  to install the packages.

                                   dpkg -i "name_of_package" 

                                

once done we are going to install some additional tools

                           
                                    aptitude install libaio1 bc

those dependencies (libaio1, bc) are needed to be installed with Oracle xe10g
and then we install rlwrap tool to make our life easier with sqlplus client

                                    apt-get install rlwrap  //(it will help us with sqlplus )

II # CONFIGURATION

           1) excute this cmd  " /etc/init.d/oracle-xe configure " (as root) and follow the steps that gives you

              2) add the following lignes in a terminal and in your user file profile  " ~/.profile "   (or /etc/profile

                           export ORACLE_HOME=/usr/lib/oracle/xe/app/oracle/product/10.2.0/server

                           export PATH=$PATH:$ORACLE_HOME/bin

                           export ORACLE_BASE=/usr/lib/oracle/xe

              3) add the following ligne in this file -> "$ORACLE_HOME/sqlplus/admin/glogin.sql" 

                           DEFINE _EDITOR = "/usr/bin/gedit" (or an other text editor that you want ) 

              4)type in a terminal the following alias and  add it  to your list of aliases , here(~/.bashrc)

                           alias sqlplus='rlwrap sqlplus'
