Oracle Database 10g Express Edition (Oracle Database XE) is an entry-level, small-footprint database based on the Oracle Database 10gRelease 2 code base that’s free to develop, deploy, and distribute; fast to download; and simple to administer. Oracle Database XE is a great starter database for:

  • Developers working on PHP, Java, .NET, XML, and Open Source applications
  • DBAs who need a free, starter database for training and deployment
  • Independent Software Vendors (ISVs) and hardware vendors who want a starter database to distribute free of charge
  • Educational institutions and students who need a free database for their curriculum

With Oracle Database XE, you can now develop and deploy applications with a powerful, proven, industry-leading infrastructure, and then upgrade when necessary without costly and complex migrations

Downloads and Documentation

First of all, you do not need to download Oracle XE installation package for Debian from Oracle Express Download Page. You do not need to do it because Oracle has its own debian repository for automated installations.

To use this reposotory you need to add following lines to /etc/apt/sources.list file:

deb unstable main non-free

deb-src unstable main

Next, you need to update your package files (as root)

# apt-get update


Reading Package Lists… Done


Now, you able to install your new Oracle XE! Just run following commands as a root user and answer for some questions about admin passwords and Oracle starting at boot:

# apt-get install oracle-xe-universal

Specify the HTTP port that will be used for Oracle Application Express [8080]:

Specify a port that will be used for the database listener [1521]:

Specify a password to be used for database accounts. Note that the same

password will be used for SYS and SYSTEM. Oracle recommends the use of

different passwords for each database account. This can be done after

initial configuration:

Confirm the password: (* make sure you remember this password *)

Now you have installed Oracle Express Edition on your Debian Sarge server.

Disabling/enabling the Oracle XE Service

Your Debian based system should meet the minimum requirements for swap space, otherwise installation would fail.

Based on the amount of physical memory available on the system, Oracle Database 10g Express Edition requires 1006 MB of swap space (YMMV). In order to overcome this issue you can always extend your partitions with Knoppix or Gparted.

The alternative solution, avoiding a reboot, would be:

# dd if=/dev/zero of=/myswapfile bs=1M count=1000

# mkswap /myswapfile

# swapon /myswapfile

You can always disable Oracle XE startup in boot time with (no update-rc.d method here):

# chmod -x /etc/init.d/oracle-xe

The alernative way to the same is to edit /etc/default/oracle-xe and change:



Web console management

If you have installed OracleXE database on remote *nix server, you can easily setup a SSH tunnel in order to gain access to a web administration console (since web console is bound to loopback device and therefore unavailable outside to the network):

# ssh oracle-xe-server -L 8081:localhost:8080

While keeping this proces running (or keep it on background via screen or nohup), you may now login to Oracle XE web administrations console on your local computer: http://localhost:8081/apex/

Please notice that your ssh daemon on your local computer should allow TCP forwarding. (ie. “AllowTcpForwarding yes” should be present in “/etc/sshd/sshd_config”.)

SQL Remote connection management

By default OracleXe installation does not allow SQL network connections to your XE database.
To enable remote connections, logon to web management console and enable “Remote connections”: “Administration->enable Available from local server and remote clients”-> press “Apply Changes”. The same procedure can also be done from the commandline:

# sqlplus -S system/password@//localhost/XE < @this_script.sql SQL> exit;

Alternatively use the web managment console to add new Oracle XE users accordingly.

Deleting users

For deleting an SQL user from OracleXE use the web management console, or execute following commands from the commandline:
# su – oracle
oracle@server:~$ sqlplus / as sys
SQL> drop user myuser cascade;
