Customers that cap their environment are typically *VERY* sensitive to
the possibility of exceeding that agreed cap. Prior to Capacity Groups
that meant setting the caps to that, and eating the resultant problems.
I have had a customer increase the total deliberately - but only after
some-one (dev team/internal customer) agreed to front for the increased
cost for the month. Same customer regularly moves capacity around, but
keep the total strictly enforced.
If devs are screaming, their management has to go in to bat for them -
either negotiate or pay for a larger capacity on that LPAR.
