On my PC I have instaled Informix Connect software as a Informix client and I traying to connect to INFORMIX ONLINE 7.22 server on SCO Unix - there is no efect. I configured every needing file on my PC ( C:\\windows\\services; C:\\windows\\hosts) and on server ($INFORMIXDIR/etc/sqlhosts; /etc/services). In services files I have the same number and name of service. I have no idea why this client can't connect to INFORMIX sever. I would like to establish this kind of connection only for test but finaly I'm going to make the connection to INFORMIX ONLINE 7.22 server using Delphi native driver for INFORMIX. HELP me answering the questions: 1.Whay I can't connect using Informix Connect ? 2.How can I connect to Informix using Delphi native driver (what shuld be set up) ?
