Need help setting up ODBC to Oracle (fabulous details inside!)

Greetings all, Recently, against my wishes, my company acquired a RUN TIME <scary music>dun dun, DUUUUUUUUUUUUUHHHNNNN</scary music> version of Informix. Confident that it was just a "licensing" issue and that the software was all the same as the full version, they charged ahead despite my warnings and red lights/flags/whatevers. Well, INFORMIX-CLI is distinctly *absent* from the software media. And from what I've heard, that is what's needed to setup ODBC connectivity to Informix OLDS. So I have two questions: 1) Is that statement true? Do the ODBC drivers themselves also come with the CLI package? 2) Where could I (if at all possible) download just CLI from? Currently, we're on OLDS7.20. TIA, Eric
