This question: https://raspberrypi.stackexchange.com/questions/7971/how-to-install-cx-oracle-python-db-driver?noredirect=1#comment36146_7971 was deleted by user 'goldilocks' with a comment: "They do now, so I presume this question is moot -- deleted."
According to this SO question: Oracle Instant Client for ARM based Debian device, this is NOT true, i.e. there is no ARM oracle db client available.
If the client is indeed available if would be fair to add a comment to the SO answer as well.
If this is not true, can you please undelete my original question?
