I.e. the current image will run only production work, the new image will run all development/test/q&a (nonproduction) work. It will be a basic sysplex because nobody would pony up the $173,000 USD to get a CFL for our z9BC. If interested, the reasoning goes that since we cannot get all of our work done during month-end because production soaks the CPU totally, the non-production work is be unjustly penalized. This will be "fixed" by putting the non-production work in its only LPAR on the same CEC and "weighting the LPARs appropriately". Nobody would believe me when I said that I could do this using WLM on a single image. They wouldn't even allow a "proof of concept" to see how a WLM solution might work.

I've used it in the past. But that alone does not seem worth the effort to implement MIA. > > Mark > -- -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology The information contained in this e-mail message may be privileged and/or confidential.
