Need help in installing openfire on a desktop.

Hello everyone,

I want to install openfire on a desktop and not server. I'll be using spark as the client and MySQL as the database. I want to use openfire for my intranet and file sharing should be completely disabled!

This chat app will be used by 100 people (simultaneously).

Will there be issues if I setup this on a desktop and not a server?

Also, what if I only use inbuilt database of openfire and not MySQL? Will this still support 100 users?

Thanks for reading. I would appreciate any help that I can get.
