There's also static power save mode. That feature debuted in the z196. If you have sustained low or zero utilization periods it's generally worth using. Or if you're running much quicker than you need to be within your batch window(s) then you might use this feature.
The word "static" is perhaps a bit misleading(*) because you can control (and automate) activation and deactivation of power save mode via Capacity Provisioning Manager (CPM), for example. You will need z/OS 1.10 or higher with OA30433. If you have z/OS 1.13, you're ready already. CPM is found in base z/OS. (*) From a purely hardware point of view -- in engineering terms -- the word "static" applies. But who cares? Do you buy a mainframe solely as a physical work of art, to install next to your Picasso? Of course not. Naturally z/OS is incredibly dynamic, and it's the end result that counts. Forgive us for underselling our capabilities. :-) As a reminder, even if I don't write it, my views are solely my own. Including my opinion that Picasso was a great artist. -------------------------------------------------------------------------------------------------------- Timothy Sipples Consulting Enterprise IT Architect (Based in Singapore) E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
