PUT2PROD was changed awhile back so that it doesn't bounce TCPIP. I don't
recall when it was changed, but I know that it doesn't bounce TCPIP on z/VM
5.4.0.

It's really up to you and your management's direction.
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. :-)

Re: Applying Maintenance - Best Practice
I suppose RSU maintenance gets burned-in at Level 2, whereas COR
maintenance goes right in to Level 1.
But , what bout PSP COR? Level 1 or Level 2.

Re: Applying Maintenance - Best Practice
I'd say it depends on the purpose of your 2nd level system. 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.

Would you recommend putting this 5.4 zEnterprise compatibility maintenance
on at Level 1 or Level 2.
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.

Re: What is the z/VM 5.4 Compatibility PTF for z196?
Also you want to check PSP on IBMLink and look for 2817DEVICE and see what
recent stuff is needed for that system type (or whatever one you are
installing).

Look at the page http://www.vm.ibm.com/service/vmreqze.html for the
complete list of z/VM APARS for the zEnterprise.

Marcy,
Thank you for this information.
Do you happen to know what PTF is needed to run z/VM 5.4
on the z196.
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.
