Dear listers, reading Cheryl Watson's last Tuning letter one sentence about the Upgrade ROT caught my attention: "Only add resources as needed. If you add more memory than you need, you'll simply cause CPU overhead". My first question is how could more memory cause CPU overhead ? Our production LPAR (z/OS.e 1.4 on a z890) has 5 GB storage assigned; RMF shows an average of 25% of the total frames as active, while the remaining 75% is available. Now and again we have jobs which do need more frames, so the percentage varies to show 60% or 70% active and 40% or 30% available, but that's sporadic. Should I consider the storage assigned to our LPAR as too much ? Any chance that the assigned storage would cause CPU overhead ?
I'd like to read your opininion/ROT on this.
