Different Informix versions on one NT/Unix box

Hello all, Can we have 2 different Informix versions on a NT/Unix box at the same time? I think on Unix we can, but not sure. I have Informix 7.31 TC2 installed on NT 4.0. When I go to the command window and bring the engine online(using oninit), it brings the engine online, but doesn't return the prompt. If I open one more window and see the online.log, it shows the instance is online. If I close the window from where I started the instance or if I do ctrl+c(as I am not getting back the prompt after doing oninit) it brings the engine offline, if I see the online.log file I don't see any message saying Informix is offline, but if I use any of the onstat commands it will say "Shared memory not initialized for instance_name" Do we need to have the window open from where we start the instance or is there any way by which we can run it in background?

I have 4 versions (7.31.TC2, 7.31.TC5, 9.20.TC1-1 and 9.21.TC1-1) on my NT box right now. > I have Informix 7.31 TC2 installed on NT 4.0.

Use 'net start' or 'starts' commands or 'Control Panel -> Services' GUI to start the engine on NT correctly. > Vinod Bhansali Leonid Vorontsov
