I took the administrative reins of our Cognos 10.2.1 server when it was already up and running, so this is my first time installing Cognos. I have what's probably a silly question but I'm having issues finding a definitive answer. In the older versions of Cognos it used Apache's Tomcat, which is open-source and I never gave it a second thought.
However Cognos now installs Websphere. I honestly don't know much about it but I know it can be very costly to set up a normal instance of it. I can't find anything online about hidden or additional licensing costs regarding Websphere as Cognos is using it, but I thought I should check if anyone has more detailed information than what I can find, which resulted in them exploring other application server options.
I imagine if there was anything about IBM charging more due to Websphere's inclusion I would have found something about it, but I may just be having a bad "google-fu" day.
