I would be carefull about having so many instances. I was running 12 instances on a SPARC 20 until a month or two ago. I posted to this group about the performance problems we had. The result was that the total SGA of all the instances shouldn't be more that 30% of the total memomry. what this means is that you will have to have a server with a LOT of memory and a LOT of processor power(consider that fact that 22 instances would give you over 100 processes running without a single user logged on) to make this work.
