When using SharePoint Designer I found this link that stepped me through how to get it working:
http://spsolution.blogspot.com/2008/12/how-to-insert-data-source-in-sharepoint.html
That allowed SharePoint Designer to talk to Oracle, but when I placed a data view on a page it gave me the following error:
Error while executing web part: System.Data.OracleClient.OracleException:

I am mystified.
