You wouldn't believe the fight I went through to get our z/OS lpars enough real to get paging below the 25% threshold when we migrated from 1.10 to 1.12. Not to mention to stop the RSM abends we experienced that IBM was unable to debug and that were most probably due to not enough real and a serialization problem somewhere. That was about 30GB of real for 10 lpars. 30GB were thrown easily at one Linux runnig under VM, on the other hand. > Customers rebelled against the constant need to update the OS we've had to > dance to over the last few years, and IBM changed its tune. As someone else said, I don't think customers rebelled. I think that IBMs own resources are spread so thin that the previous cycle couldn't be maintained anymore. Did you notice lately that BCP questions are answered from China on this forum? It looks to me like some of the development labs went there. >While I can appreciate that IBM is innovating the platform, economics like >this is really putting the squeeze on many IBM customers.

In a few years there will be 50 large mainframe installations around the world and all small ones will have been absorbed into those 50. Recent development in z/OS only helps large customers who can afford 'large' hardware. Also, I attended Bob Rogers' 'crystal ball' session at the last zConference in Berlin in May. I think he was talking about the architecture of what is now called z12EC. What I got out of that is that the instruction set for z/OS (our zArchitecture) is basically tacked on to a completely different type (forgot which). And given how much z/OS is made to look and feel like what the clickers are used to (which is the only area IBM spends development dollars on), I firmly believe that z/OS is doomed. I just hope that I'll be able to work on z/OS until I retire. Which is entirely too far into the future. How's that for gloom on a Monday morning?
