For anyone who is interested in connecting zope3 to oracle I checked in an Oracle DB Adapter to the zope repository which is using the cx_oracle library http://www.computronix.com/ utilities.shtml#Oracle it is tested against 3.0 and 3.1 versions of zope see: http://svn.zope.org/cxoracleda/ Any feedback is welcome ...
