Yes. Thanks. I would only suggest that you can add a function to
cx_Oracle to make that big ugly string from 3 parameters.
something like:

def makeDSN(host,port,sid):
	return 	"""(DESCRIPTION= (ADDRESS_LIST= (ADDRESS= (PROTOCOL=TCP)
	(HOST=%s) (PORT=%s))) (CONNECT_DATA=(SID=%s)))""" %
	(host,port,sid)
