John, Thanks for the write-up and the lead time heads-up for z/OS "next". ServerPac was due for a makeover anyway, right? Wasn't your evil twin responsible for most of the ServerPac capabilities? <grin>
And if YOU think it prudent, the rest of us should take heed! :-) Bob -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of John Eells Sent: Wednesday, April 25, 2018 4:37 PM To: [email protected] Subject: Re: z/OSMF, was How far out of date are my skills z/OSMF is a lot easier to configure now than it used to be. I've been through the entire setup, and it's not bad in my opinion. The most common sticking point seems to be security system setup. You can find the pertinent samples in SAMPLIB with names like IZUSEC (the main one) and IZUxxSEC, where xx is an abbrevation for the application name. For historical reasons, Software Management's sample is named IZUDMSEC. A rewritten configuration chapter should hit the streets soon, too, which I think will help. z/OSMF was rebased on WebSphere's Liberty Profile in z/OSMF V2.1, which dramatically reduced its CPU, memory, and disk footprints. The idle CPU consumption of the z/OSMF server is pretty low. It only chews up significant cycles if you use it to do things. That said, you can stop the server when you're not using it. You can also lower its priority in WLM, but if you go *too* far in that direction, you might experience browser timeouts if your other workloads yield high overall CPU utilization for long-ish periods of time. I have not done a comparative measurement of a ServerPac-based installation and a Software Management Deployment operation CPU consumption, but I would expect broad swaths of both to be fairly similar. ServerPac uses GIMGTPKG to get the package, and so does Software Management. Likewise, both use GIMUNZIP to load the files and data sets from the GIMZIP archives. The things that will eventually require using things unique to z/OSMF Software Management are acquiring the package (or pointing at it, if you don't have internet connectivity to IBM), doing the customization you want (data set names, catalog environment, etc.), the job management done by the final step of the ServerPac dialog, and (eventually) managing the setup workflows that we want to have replace the ServerPac product-specific batch jobs. If you want to model after something existing, which I expect most will, you will also have to define the thing to be modeled after as a "software instance" first. It's probably worth mentioning that not all of the aforementioned processing is zIIP-eligible. The z/OSMF proper part of it is mostly eligible (I'd guess about 80-85%), but many of the system services used by Software Management (DADSM, CVAF, Catalog, VSAM, etc.) are not. Those things cost the same whether we drive them from a PLI-based ISPF dialog or from a z/OSMF application. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
