MVS puts CPs into a (restartable) wait state when there is no work for them to do. I wonder if a CP in wait state is using any power at all? If so, this would be even better that merely throttling. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
