Hello,
I am trying to understand how to utilize the RMF CPU report so that I can
evaluate utilization of our CP and latent demand. The publications on this
report I have read, indicate that when LPAR Busy < MVS Busy, this is an
indication of latent demand. In the report below, this is the case (45.85 <
49.68). However, if you look at the Partition Data Report, the CP was only at
77.11%. Why wasn’t PROD able to obtain the 49.68% needed? Any input
appreciated. Thanks, Gary
