The output from those commands you list all look good for my system. It did
start spitting out messages which don't look good:
[ 1528.473303] systemd[1]: Failed to start Apply Kernel Variables.
[ 1649.605564] systemd[1]: Failed to start Journal Service.
[ 1658.599686] systemd[1]: Failed to start udev Kernel Device Manager.
(Those last two messages repeat several times.) It'd be nice to know why things
failed.

I am no Network person, but here are a few suggestions to try and ensure
your network setup is ok ...
1. D TCPIP,,N,VIPADCFG (verify zCX DVIPA has bee defined - VIPARANGE)
2. D TCPIP,,N,VIPADYN (verify DVIPA has been activated by zCX instance)
3. D TCPIP,,N,DEVL,INTFN=EZAZCX (verify that TCPIP has activated the EZAZCX
interface)
4. F jobname, DISPLAY,NET (verify zCX network config)
5. D TCPIP,,N.HOME (verify the EZAZCX IP address and zCXDVIPA have been
added to the Home List)
Hope the above helps

The devil is in the details. There is a discussion in authorized services.
Briefly, for a type 1 SVC, you suspend the current RB, schedule an SRB or
whatever, and ultimately exit normally. When you exit, the suspension takes
effect.

Thanks, Seymour, for the info about type-6s.
WRT GUPI, like most other ISVs, I use them when I can, and accept the
occasional recoding obligations when I can't.
My real question is... What happens when a type-1 SVC SUSPENDs? (Or
for that matter, when any other locked or disabled environment SUSPENDs?)
Thanks,
Dave

As I understand it... a type 1 or 6 SVC cannot SUSPEND, WAIT, or PAUSE
synchronously at all. If they need to finish something later, they
schedule it and quit.
The differences between type 1 and 6 (and the others) are discussed in the
MVS Auth Service Guide.

If you display the information for z/OS UNIX processes running in these
address spaces, you can see the specific program (command) that is running in
them.
Options:
- Under SDSF you can use the "PS" panel to see running processes for OWNER
OMVSKERN. The "CMD" field shows you what program is running in the process.
- The "ps" command under a root shell
- The D OMVS console command

Subject: FW: IBM RFE's Broken
It appears that the IBM Developerworks RFE portal is being migrated to
something new. During this migration, the old RFE portal is useless, and the
new portal is also useless. I tried to vote on an RFE that I was notified
about 2 days ago and found the link is broken. I went to the RFE portal and
tried a search, and the result was a broken url. I tried to enter a new
idea using the new portal and the product selection does not work.
I hope IBM gets this working again and that the new portal (Aha!) will have
a least the same level of functionality that the old one had.
