ty, Mike, for the nice writeup and the headsup on PUT2PROD and TCPIP. Our 5.4 level 2 test environment is not really there, unless our old 5.2 Level 2 is still lurking around. At least it is still in the directory.
If it is, I suppose I can just DDR my 5.4 disks to the old 5.2 disks (if we still have them) and recreate a 5.4 Level 2 test environment. After reading your writeup I don't see how I can do without it.

If you only have one system to maintain, once you get the hang of it it's not really all that hard to: 1) apply all maintenance to the 2nd level test system, 2) IPL the 2nd level test system, 3) perform some cursory (or more stringent, depending on your tolerance levels) tests, 4) only then re-apply the maintenance (or copy minidisks if you really know what you're doing, which VMSES/E makes more difficult) to the 1st level system and schedule its IPL. Applying the same maintenance twice can be viewed as tedious, but it does breed a bit more familiarity with the VMSES/E command set. But it also give you a chance to see what will be changed when you run PUT2PROD on 2nd level. Some components are not especially good to run PUT2PROD on in a production environment (can you spell: TCPIP?) when users (and your management) might notice that component being bounced. BTW, after applying maintenance I consider it a good idea for each of the component which were serviced, to use VMFSETUP so that their disks are linked and accessed, then issue: FILELIST * * * (TODAY ISO then browse around to see what was changed. That breeds even *more* familiarity with VMSES/E and what it has done for you. That familiarity can be handy when something goes bump in the dark. :-) Mike Walter Hewitt Associates The opinions expressed herein are mine alone, not my employer's.

But , what bout PSP COR? Level 1 or Level 2.

Do what you would normally do when applying maintenance... do you put it on 1st or 2nd level first? If your 2nd level system is meant to be a z/VM 'test' system, then it seems like you're already committed to that level of effort.

We currently have both environments for 5.4. I suppose the quickest and easiest (maybe dirtiest too?) way is just to put it on at Level 1 and fall back to CPOLD if there is a problem. "Best practice" may call for putting it on at Level 2 first, but the nature of the change may not warrant that level of effort. There are, however, 45 or more prereq fixes also going on with these 2 APARs, VM64879 VM64881. Just interested in what everyone thinks.

We will probably take your advice. We will probably bring up the z196 with 5.4 first and then move 6.1 up to Level 1 afterwards. -- Bruce Hayden z/VM and Linux on System z ATS IBM, Endicott, NY The information contained in this e-mail and any accompanying documents may contain information that is confidential or otherwise protected from disclosure.
