While you’re thinking by installing 64 bit linux you’re standing in the edge of new technology era, it sucks knowing our 64 bit system is less supported than the old 32 bit system. We have to install 32 bit flash since Adobe didn’t have the 64 bit one. We have to install 32 bit oracle xe since Oracle also didn’t have 64 bit version.
And now I will try explain how to install oracle xe into the 64 bit system, ubuntu way. Of course we couldn’t follow the guide from oracle, since apt-get will detect our system architecture and we won’t get the 32 bit packages list.
Before we start, make sure you have the 32 bit library installed. It’s in reposity, all you have to do is
sudo apt-get install libc6-i386
wget -c http://oss.oracle.com/debian/dists/unstable/main/binary-i386/libaio_0.3.104-1_i386.deb http://oss.oracle.com/debian/dists/unstable/non-free/binary-i386/oracle-xe-universal_10.2.0.1-1.1_i386.deb
After your downloads are finished, we continue to the main issue, forcing the package to be installed. You could try to install with usual dpkg -i first to make sure your system is really 64 bit.
sudo dpkg -i libaio_0.3.104-1_i386.deb
You’ll get error,
dpkg: error processing libaio_0.3.104-1_i386.deb (--install):
package architecture (i386) does not match system (amd64)
Errors were encountered while processing:
Added guide from Venka A
sudo apt-get install bc
To force the installation, do these
dpkg -i --force-architecture libaio_0.3.104-1_i386.deb
dpkg -i --force-architecture oracle-xe-universal_10.2.0.1-1.1_i386.deb
And after the installation is finished, you need to configure it
sudo /etc/init.d/oracle-xe configure
and edit your ~/.bashrc
And, voila, the oracle xe is ready. You could go to http://127.0.0.1:8080/apex from your browser.
