Hi Lukas, you will need a working oracle OCI client middleware before cx_oracle can talk to your database. The easiest nowadays is the so-called instant client, which must be available from the otn.oracle.com site (downloads might require a free registration). Try to get sql*plus working (the standard Oracle command-line client), and cx should then pose no problem.
