How will you handle if the system simply cannot handle
more requests per second?
I change the subsystem class for all the ODBC/JDBC database server jobs to a
time slice of 1 millisecond, and knock the run priority down to 99, and allocate
just 1 meg RAM to the subsystem. We only need those jobs for serving .Net and
JEE clients. It's fun to irritate those people. That frees more resources for
all our RPG CGI programs ;-)

Okay, if your box is pegged at 100% CPU utilization 24X7 and customers begin
complaining about performance, then you call IBM and order the activation key
for a capacity on demand upgrade. You enter the key, and suddenly your server
is running on 4 sockets instead of 2. CPU goes back down to 50%.
Ok, sounds very easy.

How expensive is such a "capacity on demand"-upgrade, and what do you do when you run out of these upgrades or they get too expensive?
