Oracle XE – Speeding up Startup and getting Nofications on the Desktop in Ubuntu

Oh the tension. 2-0 up at half-time. Visions of last-day drama and an eleventh-hour escape floating tantilisingly before my eyes. Then, grim reality. A second-half collapse and the prize is snatched away once more. So, this is what it must be like to be an Arsenal fan.
I know that they say misery loves company, but it’s not really any consolation. Yes, my beloved West Ham have been relegated from the Premiership.

One other point worth mentioning is that Oracle 11gXE is now available. Many of the issues in this post are still relevant. However, if you’d like to know how to install the latest XE on Ubuntu or Mint, here are the instructions
