I have had success with the following connection string:
db = DAL('oracle://user/password@sid')
I tried out the alternate form you used:
db = DAL('oracle://user/password@server:port/service_name')
And it worked successfully. When I used a bad password or
a bad service_name I saw a similar error to what you reported:
Traceback (most recent call last):
