Umm, no. Anyone with a z10. Not emulators.

Still isn't. 

I agree with your arguments -- I'd love to see a hobby license for VM, but
this isn't it.

Re: Installing IBM z/VM to Hercules

[Dave Jones]

Hi, Marc.

The unfortuate status of the z/VM 5.3 evaluation version is
that it's license from IBM states that it can only be
installed on a z10 system. Installing it anywhere else would
be a violation of the license terms.

Yes, Hercules can run the evaluation version, so I've been
told, but not legally. I'd like for IBM to offer some sort
of hobby or non-commerical or educational license for z/VM,
just so folks like yourself, newcomers to thjis operating
system, could have some hands on experience at a very low
cost point, but that's not happened yet.

One thing you can do is follow this lista lot of
advanced z/VM features and uses get discussed here by some
really sharp VM-ers.

Have a good one.

FTPSERVE delayed release of RW disks

[Colin Allinson]

Something that we have just noticed - but may have been with us for a 
while. 

We have found that after we open an FTP session to a VM minidisk, FTPSERVE 
retains the RW link for about 2mins 45sec after the FTP client has broken 
the connection with a BYE or QUIT

Can anyone throw any light on this and is this controllable?

With what client?  When I do it with the Windows or CMS ftp client to a 
z/VM 5.4 FTP server, the disk is detached immediately, as expected.

It is a Windows client.

OK - that is good assurance that I am not going mad. I am beginning to 
suspect that something in the network has changed to make the connection 
more persistent.

Hello Marc Schoechlin,

Hercules can run most IBM z/xxx products along with the older VM/ESA and VSE 
products.  BUT... it is highly illegal.

The Wrath and Fury of IBM LEGAL will ascend from the sky. 
And you will be told to "CEASE AND DISSIST NOW!"  with great emphasis on the

Hi,

i'm really interested in getting a deeper understanding of IBM z/VM. 

I was very happy that IBM offers now a evaluation version of z/VM 5.3 to 
everyone:
http://www.vm.ibm.com/eval/

I really like hercules to play around with Linux for zSeries - but is it also 
allowed
to run this z/VM evaluation version on hercules ?
As i can remember, this was not allowed in the past.

How can i install the z/VM eval version on hercules? 

Are there any redbooks/howtos available?

Question on SERVICE EXEC and PUT2PROD

[Karl Kingston]

We're about to apply some RSU's to our current 5.3 system.System has 
been running great without issues.

Right now, I'd like to minimize the downtime for our users.Since we're 
running z/Linux with production servers.

Is running SERVICE EXEC distruptive to the running system?   I would think 
PUT2PROD would be.

Can I run SERVICE to apply the service and then at a later time when we 
schedule an outage, I can run PUT2PROD and SHUTDOWN/re-IPL?

Thanks

Re: Question on SERVICE EXEC and PUT2PROD

[Marcy Cortes]

Neither service or put2prod are disruptive to the guests.
It's the shutdown that will be :)

Run SERVICE at any time. When you are ready run PUT2PROD and  re-IPL.  
Unlike some systems  PUT2PROD will not force a re-IPL but you should do 
one soon after it runs if there were updates to the CP NUCLEUS on the RSU.

It's very difficult to get z/VM systems (with full maint privileges)

In my opinion, IBM wastes a lot of market opportunities by
fencing out zSeries newcomers with a highly restrictive licence.

Re: Question on SERVICE EXEC and PUT2PROD

[Kris Buelens]

Updates to the CP nucleus would never require a reIPL in a short time: the
CP nucleus resides in storage, storing a new one on MAINT CF1 doesn't harm
at all.
However, if there are updates to the CMS resident, many CMS users are at
risk after PUT2PROD, you can restart them one by one or by a reIPL.
For GCS, even SERVICE is a bit disruptive: the GCS saves system is replaced,
what means an IPL GCS will fail untill the GCS recovery machine (hence all
other GCS users) are restarted.  Q NSS USERS GCS will reveal which of your
users might be affected.  Without SNA, RSCS is probably the only user.

For non-SNA networks, I prefer to run RSCS in single-user (GROUP=NO) mode 
so that there is no recovery machine and it can be treated like a 
stand-alone CMS user.

Re: *SIGNAL Service Experience

[Gary M. Dennis]

Thanks.

The following is from some tests we conducted to compare *SIGNAL to straight
IUCV. 2097 Dallas Development, second level VM, under CMS.

100,000 signal / acknowledgement transmissions. The straight IUCV test sent
only 8 bytes to try and put it on equal footing with *SIGNAL.

4 *SIGNAL tests - ran 5 seconds each over a 2 minute period.

4  IUCV  tests - ran 5, 7, 7, 6, 7 seconds over a 2 minute period.

The IUCV tests seemed insensitive to transmission size.  Whether we sent 8
bytes or 32,000, the 5 to 7 second window held.

Install the demo system there. There's plenty of space, and that actually
might be a legal venue. And you can do anything you want to the 2nd level
system. It'll perform like a hyena with a bullet through it's head, but then
again, it's for educational purposes, and that should be more than
sufficient for your purposes.

I am not a lawyer but the wording in the license is, to me, really odd. It
starts by saying it will run on a Z10, but it doesn't say you can ONLY run
it on a Z10. It actually says:-

"You are not authorized to install or use this Program on any machine that
does not properly implement 64-bit z/Architecture"

I am not sure if that means if any one still has a licensed version of FLEX
with 64 bit support they could run it.

Actually most Hercules machines can't run the Eval as it needs 3Gb of
memory, which most users can't provide...

OK, but Q ALLOC PAGE doesn't change and I would guess that

would think the "ALLOC" part of that command means it shows

Re: Question on SERVICE EXEC and PUT2PROD

[Schuh, Richard]

Rather than GROUP=NO, there is an entry for "Single User Environment (YES or 
NO)". Above that line, there is one that asks for "RECOVERY MACHINE USERID 
(required)"

The note dealing with the single user entry reads:


5. Will the GCS system run in a single user environment?

Enter YES to create a single user environment. Specify NO, to create a

group environment with common shared storage.

Applications that do not require group communications and that run

without the use of shared common storage can run in a single system

environment. These applications will run without the overhead of group

initialization and multiple virtual machines. For example, a test

environment requiring a single user and not group communications will

be able to run without the overhead of group initialization and the

multiple virtual machines.



I take that, "the multiple virtual machines," in the last two statements to 
mean other machines like VTAM, ACS and buddies, but does not include the 
recovery machine (which is, per the display, required). The note related to the 
recovery machine question states that the GROUP command does check the recovery 
machine userid for validity, "but does not prevent you from saving an incorrect 
entry." What does that mean? You can put in something that would be acceptable 
as a userid, even though there is no such id in the directory, or it must be an 
existing id, even including one that is NOLOG?

All of that begs the question, how do you accomplish running without the 
recovery machine? Do you simply enter an id and never log it on? I know that in 
multiple user mode, GCS refuses to come up in RSCS or any other machine in the 
group if the recovery machine is not already on. The documentation is perfectly 
clear (to the one who wrote it).

I'd say the recovery userid you specify will be ignored.

In fact, in such a "single user GCS" userid you could run RSCS, VTAM, VSCS,
and AVS together, they are all multitasking.  An abend in one would cause
the death of them all.  That's -I guess- why the help mentions "test
environment".
The GCS recovery machine is mainly meant to be able to cleanup the common
storage gotten by a member when that dies.  E.g. when VTAM starts, it tells
the recovery machine to run program ITS when it would die, it would
FREEMAIN the storage gotten by VTAM.  In a "single user GCS" system there is
no such problem of common storage that must be freed in case of abend.

The savings of *SIGNAL would be the use of the broadcast function. Instead 
of UserA sending to UserB, then UserC, then UserD, and so on, userA just 
broadcasts the IUCV data, saving an IUCV SEND operation as well as the 
logic to keep track of B, C, and D (which *SIGNAL can help with, too). For 
two guests, the savings would be zero.

What scenario did you compare?

Re: Question on SERVICE EXEC and PUT2PROD

[Schuh, Richard]

Are you saying that in a single user environment, it is unnecessary to even log 
the specified recovery machine on? If not, is it even necessary to specify a 
real id?
It appears that what is being implied, but not stated in this thread, is:

1. For a single user system, you must specify an arbitrary recovery machine 
userid simply for purposes of having it included in the NSS. (Why can it not be 
blanks in this instance?)
2. That userid does not have to exist because it will never be logged on. (Does 
anything bad happen if it is defined and someone logs it on and IPLs CMS? 
Probably not, but it most likely would be a bad idea for it to be allowed to 
IPL GCS.)

I have, over the years, frequently heard, "Do not infer anything, especially 
when dealing with IBM systems. If it is not explicitly stated in the 
documentation, you cannot assume that it is so." Here, it appears that we must 
trust that our inferences match the intended implications.

The ATTACH  SYSTEM did the trick. All is well now.
THANKS for all the replys !!

Re: Question on SERVICE EXEC and PUT2PROD

[Kris Buelens]

It is indeed not required to XAUTOLOG a recovery machine if a "single user
GCS", it won't be used, it has no role to play.

Maybe REXX code behind the GROUP panels aren't clever enough.  In fact, what
you enter there is saved into a "fn GROUP" file, but will also be copied in
"fn ASSEMBLE" and that is assembled, yileding "fn TEXT".  Maybe the
Assembler macros are more clever and don't require a recovery userid for
"single user GCS" systems.
I never used the GROUP panels anymore since VM/SP R6, I used the ASSEMBLE
file, what allowed me at that time to make overrides to make GCS variants
depending on the target system. Hence the panels are not fresh in my mind.

That is correct.  There is no recovery id.  When each user IPLs the 
single-user GCS, they are not joined into a group.

Just specify it as "*" (like the DUMPVM= default).  But it doesn't really 
matter.  In single-user mode, the recovery and dump machine values are 
overridden at IPL time anyway.

See above.  A single-user mode GCS is automatically RESTRICT=NO, so anyone 
can IPL it.
