Database development and management are activities that are meant only for professionals, given their complexity. Nonetheless, even the most experienced specialists will surely need the most powerful tools in order to successfully and easily carry out their work-related tasks.
One of the most efficient packages in this category of utilities is Oracle Database Express. Geared up towards building and deploying databases and related applications, this tool facilitates the development as well as the administration of such software.
Also going by the name of Oracle Database XE, this piece of kit comes with extended support for a variety of network protocols, including IPC, TCP/IP, TCP/IP with SSL, SDP and Named Pipes. Developing apps can be done in one of the environments that Oracle Database Express is compatible with. These are Oracle SQL Developer, Oracle Application Express, .NET and Visual Studio, PHP and Java.

- Oracle Database 11g Express Edition (Oracle Database XE) is a free version of the world's most capable relational database. Oracle Database XE is easy to install, easy to manage, and easy to develop with.
An important mention related to the installation of Oracle Database XE is that it will require that the user deploying it is part of the Administrators group. It is possible to set it up as a domain user, but only if you are connected to the network prior to starting the procedure.
From the administration console of Oracle Database Express users will be able to view the status of currently used storage, database sessions as well as initialization parameters. In order to create database objects, a user has to be created and configured, a task that, just like many others, will have to be carried out via command-line.

Download
Server
You can download Oracle 11g Express Edition (XE) Server from Oracle's Oracle Database Express Edition 11g Release 2 Download page. You will need an Oracle OTN account to download the rpms and you will need to accept the license agreements. Download the 'Oracle Database Express Edition 11g Release 2 for Linux x64'
- oracle-xe-11.2.0-1.0.x86_64.rpm
Client
You will also need the Oracle Instant Client rpm from Instant Client Downloads for Linux x86-64 page. Download the following two rpms:
- oracle-instantclient11.2-basic-11.2.0.4.0-1.x86_64.rpm
- oracle-instantclient11.2-sqlplus-11.2.0.4.0-1.x86_64.rpm
Before installing Oracle XE
You must run the following two commands before starting the installation to create the oracle user uid below 500 (below 1000 on Fedoras), to be able to run Oracle XE with SELinux enforcing:
Check if you have swap > 1GB because Oracle XE RPM will need it. You can create temporary one (or grow existing) with
Ensure your hostname is resolvable either with by DNS or an entry in /etc/hosts. Otherwise the configuration of the Oracle Net Listener will fail.
Install
Make sure bc is installed
The bc is a dependency of oracle-xe which is not resolved automatically. Therefore, run:
Oracle XE itself
The --nogpgcheck is required because the Oracle RPMs are not signed.
Oracle Instant Client

- WARNING: Don't run
oracle_env.sh
ororacle_env.csh
in your root environment settings. Instant Client stuff works fine without it. It's useful only for command line XE server management underoracle
user.
Oracle compatibility library
To install oracle-lib-compat, you'll need to have the Spacewalk repo configured, see HowToInstall for installation directions. Run:
This will likely pull in
compat-libstdc++-33
.Install SELinux Policy
If you are running with SELinux enabled then install the following packages from the Spacewalk repo before running
oracle-xe configure
:This will likely pull in
oracle-nofcontext-selinux
as well.Server Setup
Configure the Oracle XE database by running
Here are some sane values for the configure:
Note that the port 8080 is used by tomcat so you cannot accept the default for the Oracle Application Express. Also, the SELinux policy module assumes that the Application Express port is 9055, if you want different value, you need to define it for
oracle_port_t
via semanage
.Oracle Database 11g Express Edition Download
Note that Oracle does not like certain characters in your password, but will not tell you until you can't login as sys later on.
Rerunning the configure
If you find out you are not happy with the configuration, remove the oracle-xe rpm and start anew.
Test your connection with sqlplus
Replace with the password provided on /etc/init.d/oracle-xe configure
Run
You should see something like
Create the spacewalk database user
Replace with the password provided on /etc/init.d/oracle-xe configure
Test that
works.
Additional Oracle configuration
Oracle XE is initially configured to grant 40 connections to its database. Spacewalk needs more than this default configuration. We recommend increasing this setting to 400.
Oracle XE has a bug that causes an Internal Server Error (500) in Spacewalk when viewing Systems -> Pick a System -> Software -> Packages -> Install New Package(URL: https://spacewalk.example.com/rhn/systems/details/packages/InstallPackages.do?sid=**********) or when running
rhnreg_ks
to register a client.In order to avoid these two problems we need to increase the max processes in Oracle and to
{{{
SQL> alter system set processes = 400 scope=spfile;SQL> quit
}}}
You might want to install 'rlwrap' to make your sqlplus more usable.
rlwrap
will retaina 'curses' like behavior with sqlplus such as maintaining sql call history, etc.You can then do
{{{rlwrap sqlplus spacewalk/spacewalk@//localhost/XE}}}
Troubleshooting
- If you get errors such as:
or anything from Oracle complaing that it can't extend an index, a table, etc.. you should run:
Quit sqlplus and restart spacewalk and oracle-xe (may not require a restart)
- If you run out of space in Oracle XE you can try and reclaim some space by shrinking your storage:
