Oracle XE is available for 32-bit architecture (i386) Linux only, although it may be possible to force installation on a 64-bit host. It will run in 512KB RAM but requires a 1GB swap space. Add:
deb http://oss.oracle.com/debian unstable main non-free
to /etc/apt/sources.list and then as root:
wget http://oss.oracle.com/el4/RPM-GPG-KEY-oracle -O- | sudo apt-key add - apt-get update apt-get install oracle-xe
‘libaio’ and ‘bc’ are in the repository, so dependencies will pull them in if the user doesn’t have them.
