When I've had this problem, it was because I was not including the library
correctly. DCOracle2 is installed in the Products directory, and Zope (and
the DA) know where to find everything.

I have never tried to create a database connection from a Python script, so
I'm not sure the security mechanisms allow it. But my understanding of the
way Python scripts are handled suggest that is a bad place to do database
connectivity because of the extra security context checking.

The problem in External Methods is likely a namespace issue. Try something

from DCOracle2 import DCOracle2
dbconn = DCOracle2.connect("....")


from Products import DCOracle2
dbconn = DCOracle2.DCOracle2.connect(...)

It's been a while since I did that, but something like that did work.
