Nothing ever goes to prod unless its not thru the migration process, if a PTF is needed for prod and our sandbox is not fully tested (which has not happened) it gets applied to the test lpar's sysres. I understand the scenario you're talking about, I've just never had the need to apply a PTF on PROD without going to test first. time is on my side, my team tests as soon as I IPL the test system (sandbox), so that scenario has not happened, and I'm prepared to move that service to prod, with a needed PTF. and again, it all depends on what the specific PTF touches, some are compile lib update, mac updates, rexx.....so many different scenarios I don't roll out maint or service levels but once or twice a year, that's mandated by leadership, so maybe 4 IPL's per year, RSU at 6 month intervals , and RSU+TOLERATION before I freeze the systems and start the next ServerPac install I can't speak to every scenario, but again, at this small site with mainframe going away and more and more distributed applications, this process works well. so I guess, I'll keep my fingers crossed behind my back and say "I've never had to apply an emergency PTF" on top of a prod system when my latest RSU level is still being tested.

If you apply it to the test system and copy, then you be running the new service level before you've finished testing it. -- Shmuel (Seymour J.)

I've not, so far had a requirement that I need to maintain a third SYSRES or multiple target zones for the OS I am prolly not making this sound easy and not posting this correctly, but I have a documented process that I've been using for many years that works well, even in a TEST PLEX / PROD PLEX 6 LPAR environment. difference now is I have a smaller environment and this methodology lends itself well to these maint process. if needed I have a third SYRES available in my back pocket Carmen Vitullo ----- Original Message ----- From: "Seymour J Metz" <sme...@gmu.edu> To: IBM-MAIN@LISTSERV.UA.EDU Sent: Wednesday, March 13, 2019 1:09:01 PM Subject: Re: SMPe "rollout" of maintenance That lets you install a PTF on the sysres that matches your target zone, but what happens if you need the PTF on a different sysres? -- Shmuel (Seymour J.)

My preference is to always clone a new Target and distribution zone before applying maintenance. When a Target zone is no longer needed i.e. there is no system running that level of the code and there is no need to go back, the old zones can be deleted. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
