Further to Bonnie’s point, I think I’d want to deactivate unused LPARs to get
the weights and HiperDispatch to work right for the active LPARs.
But tell me, how long should it take to activate an LPAR prior to IPL’ing it?
Thanks, Martin

Gentlemen,
First, thank you for the discussion. That also helps.
Ad rem:
1. The is no big reason to keep LPAR Activated, Not operating, except
short time between activation and IPL or re-IPL, etc. And SCRT is IMHO
not the most important reason for that. Good reasons were presented by
Martin.
An interesting question is how to tell – from RMF – if an LPAR is shutdown but
not deactivated. In my own code I use the term “idle” – which means near zero
CPU – as that’s the closest I know how to get.
Cheers, Martin

Interesting topic
We have a starter system, outside of the one Sysplex we have on the same CPC
It is one LPAR, limited to 10% of a CP and runs nothing
RMF/SMF data collected indicates peak MSU at 1 or 2 for the month
Yet, IBM insists that we include that data in the monthly SCRT reporting

Of course HMC also shows OS name and version (it is 10+ years old feature).

So I hope you all dont mind a general question...
We have the common struggle of dealing with non-mainframe developers accessing
z/OS (programs, jobs, DB2) and an attitude that we need to leave the mainframe.
In trying to leverage our z/OS environment, might ZOWE (and the required zOSMF)
SCRT uses the GP dispatch time of the LPAR, from SMF70EDT, to determine
if the LPAR is active. (Dispatch times for _all_ LPARs on the CPC
are available in the SMF records from each individual system).
For any hour in which an LPAR has non-zero dispatch time, and no
SMF70/89 records, SCRT will rep

However this is one of the tests I'm not going to perform, unless in IBM

Just my $0.01 (not worth $0.02).
These developers who want/need access to z/OS and don't want to learn how to
work with z/OS, don't they learn new things all the time - new IDE's, different
operating systems (windows, macos, flavors of linux, unix, ...)? IMHO it is
easier to learn the TSO/ISPF
I agree!

Hi -
I don't see anything new or different here. When you acquire your portable
software instance, you'll need enough space to hold the order. Just like the
old RECEIVE job needed in CustomPac. Why couldn't you use the same zFS? I'm
not sure I see the value of keeping a separate directory

Yes, explaining to them that files are not an unstructured byte stream but a
collection of structured records (with no line endings!) tends to elicit
confusion. The most interesting way to explain it I once saw was to describe
file allocation as "setting the SHAPE of the file so the system know
