I had a need to bulk update user profiles in Cognos and didn’t have immediate access to a bulk update tool like Motio Pro from http://www.motio.com or the time to try and learn the API.
Googling I found this discussion http://www.cognoise.com/index.php?topic=22530.0 , where some resourceful people managed to dissect the user preference form and translate it from a POST to a GET request, but unfortunately missed a step so it doesn’t quite work (see last post).
I did more desperate digging. Here is the working version. Take any of the three following URLs — depending on the configuration of your Cognos environment — and only append settings that need to be updated.
PS. The CAF firewall needs to be disabled for this to work (disable through cogconfig.bat).
