Multiple Configurations in Online 5.05.UC1

Hello Informixers! I have two configurations on a single machine (HP 9000/E35, HP-UX 9.04). One for development purposes and the other for the production environment. Both of them has a separate installation of Informix-OnLine 5.05.UC1. Development/Maintenance : /usr/bas/mant/informix Production : /usr/bas/prod/informix THE PROBLEM: When I run tbinit with INFORMIXDIR=/usr/bas/mant/informix I cannot run tbinit with the other INFORMIXDIR, because it tells me "shared memory already exists". I have done this before in an UNISYS 6000 and it runs fine! THE QUESTION: what can I do for keep working both installations? I already tried setting the environment variable TBCONFIG. It didn't work neither! TIA ////// +------------------------------ooo-O-O-ooo--------------------------------+ | U | | Melvin Perez Cedano Santo Domingo, Dom.
