Do you have any capacity planning tools other than RMF raw data? Your most favored workloads of DB2 and CICS...are they maxing out when dispatched on one processor? For CICS workloads additional processors are not much help if you are using all of a single processor...it's just the architecture...DB2 is a different story....are you artificially constraining workloads via WLM... latent demand is not easy to identify without something like Mainview or IBM's performance mgmt suite. You really need to know where you sit today in order to project what latent demand might be...ie do you need to add more databases or increase the number of transactions thruput...not a simple answer to any of these...

I assume it may be possible to gather info about a latent demand for a processor. Where to look at in RMF, or in SMF to find this out? What about DB2 and/or CICS? DB2 and especially CICS do offer more and more parallellism. Any ideas if we can find this out within these subsystems?
