automating database update

Hello, Could kind gurus out here help me with this? I maintain a system where SCO OpenServer 5.0.2 and Informix SE5.06UC2 are teamed up to monitor and process our outgoing phone/fax calls by logging the raw data on the campus PABX. Recently, there has been the need for us to access the phone call database from workstations running Windows. We do not have I-Net so we can't connect to SCO box directly. In the interim period before the proper upgrade I temporarily work around by: -install SE7.2 on a RedHat5.2 box -install ClientSDK (I-Connect + Intersolv ODBC3.xx) on workstations -dbexport the main database from SCO/SE5.06 and dbimport into RedHat/SE7.2 -workstations connect to RedHat box to access the phone database Daily, there is a table which details the phone calls on that particular day added to the database on SCO box. The size of the database is about 400MB at the initial export/import so doing subsequent export/import is not practical. To update the table on RedHat box I use UNLOAD/dbschema/LOAD to do the job manually. It is not a complicated work to do a table each day but it is quite tedious. My first question here is, can someone suggest the methodology to automate this process? UNLOAD/LOAD (as the relevant manuals described) requires DB-access and it is beyond my knowledge of shell-scripting/cron schedule to make it work. Second question concerns Informix license of SE7.2 for Linux (ACN#A287337/BECZJK). During the installation, If I'm not wrong, I saw the message flashed across the screen somewhere saying that the license will be alive upto 31/Dec/1998. What will happen afterward? It's a worry as our schedule for the upgrade won't come along till around March of next year. I apologize if this issue was addressed in this forum before and I missed it somehow. Thanks Ampon.
