Boy Dave, you are aggressive with your TSO goals. Here we have them set
as follows. I do like your third period though. If they are doing
something in TSO that takes that much service than put them in never
never land.
Duration Imp. Description
800 2 80% complete within 00:00:00.500
3 Vel=60
Of course we need to be sure that TSO doesn't hurt out bread and butter
CICS transactions which are set at 85% within 00:00:00.150 and
importance level of 1.
