James, Have you consulted any specific LinuxONE or Linux on Z network performance tuning documentation yet? There are many other parameters and settings that can influence performance.

I learned a lot from your discussion. Thanks. My question was from a network micro benchmark test which simulated OLTP workloads generating packet less than 200 bytes typically. And our result was only half of the x86's. It's easy to re-produce using uperf/netperf by sending huge amount of small

Re: Are z14 pre-reqs dynamic?

For z14, you DO need to update (rewrite) anything that can be loaded from the HMC. This includes SAPL (use SALIPL to update *after* you have installed the service) and stand alone dump. Also make sure the correct versions (latest levels) of the modules on the parm disk (MAINT CF1) that can be

The drawback to waiting for the new hardware to IPL as Scott suggests is that if something goes wrong, you don't know if the problem is with your new CPLOAD MODULE or the new hardware. It's safer to change one thing at a time. Dennis L. O’Brien Vice President Consultant II, z/VM Engineering

Since they are to CP - no - you need to load the newly rebuilt CPLOAD. But since you will be doing that anyway when you move to the z14, I don't see an issue. Just apply the maintenance, do a PUT2PROD and you should be ready to IPL on the z14. (or come up with it if you have an unexpected

Are z14 pre-reqs dynamic?

Greetings list, Like many places, we don't have a lot of prep time and can't afford many outages for maint. That said, we're looking to upgrade our 630 systems for the move over upgrading right away to 640 with all the pre-reqs. While so many fixes now being dynamic, I am hoping that the

Greetings Gadi, As most of zuess and zoom are written in bash, you can get a taste of it via any Unix, Linux, Macintosh, Windows or (theoretically) MVS Unix Systems Services (USS)... That said, your mileage will clearly vary. :^) Regards, Flint On Sun, 22 Oct 2017, גדי בן אבי wrote:
