Thank you Mirtheil. Can the Linux client and ODBC act as an interface to the windows server? Or does it just connect to the Linux BTrieve server? (I would try it myself but I'm in a small operation will no Linux resources and don't want to confuse the issue, our SOLARIS people are used to their vendors resolving all their issues for them. They had not even heard of BTrieve and Infomartica has steered them on.)
I have been trying to ascertain the answer to that question through forums/google/pervasive but could find no definitive answers. I'll be looking into the JDBC option pending the outcome of this investigation, and providing them with daily extracts as a stop gap measure until we resolve this properly.
