Installation Oracle Express ubuntu

Installing Oracle on Debian is fairly easy, since Oracle has created a Debian repository, so it is possible to download and install the Oracle database software using apt-get and aptitude.

Howto use the Oracle Debian Repository:

Add the following lines to the /etc/apt/sources.list

# Oracle Repository
deb http://oss.oracle.com/debian unstable main non-free
wget http://oss.oracle.com/el4/RPM-GPG-KEY-oracle -O- | sudo apt-key add -

Update the package repository database with:

cc@ray:~$ sudo apt-get update

Now you should be able to install the following Oracle software:

libaio
oracle-xe-client
oracle-xe
oracle-xe-universal
Install the Oracle Express packages

sudo aptitude install oracle-xe oracle-xe-client

Configure using:

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

Access the nice Oracle web interface by pointing your Firefox to:

http://127.0.0.1:8080/apex


Updated:
The installation process might report that the Oracle packages are not gpg signed, but you should be able to install the packages anyway.

You can avoid this report by added the Oracle gpg-public key to your apt-key chain

wget http://oss.oracle.com/el4/RPM-GPG-KEY-oracle -O- | sudo apt-key add -
