TERMINAL CONMODE 3270 and TERMINAL SYS3270 are mutually exclusive.

Make sure that the attributes of your 3270 session aren't bizzarro.  E.g. 
keep it at 80 wide by no more than 43 deep.  There is a limit to the 
amount of data the integrated 3270 can deal with and you will have noticed 
that the HMC's 3270 emulator is, uh, somewhat lacking in the flexibility 
department.

But I would still open a PMR.

I normally use conmode 3270 for the IPL but I wanted to experiment with sys3270 
and they're incompatible settings

Re: IPL VM guest to virtual SYSG?

[Romanowski, John (OFT)]

Thanks,  I didn't do CMS SET CONCEAL ON, but I was in CMS when I did cp 
terminal sys3270 on
I started with the guest logged off, did LOGON, cp terminal, etc

In any event, after a few more trys of CP IPL .. the guest's been in 
LOGOFF/FORCE pending for 2 hours and looking thru the list archives I'm luckier 
than this guy in Feb 2006 who got PRG004 trying IPL to SYSG:


" I tried using SYS3270 and I abended our z/VM 5.1 system. Maybe I didn't set
it up properly but I didn't think it would cause a PRG004. I have a console
set to TERM CONMODE 3270 and SYS3270 ON. I do an IPL 6528 CLEAR LOADP SYSG.
I do not get a SALIPL screen only a VM read. Then the first level VM system
crashes with PRG004. I am doing this on a z/900 in native mode (no LPARs).
Should this work?"

Just a thought:
Maybe you IPLed CMS first and run with SET CONCEAL ON: the TERM SYS3270 ON 
kills CMS but CONCEAL ON makes CP to reIPL it

Use 'term conmode 3270'.

Re: V-disk

[Bill Bitner]

I still don't really understand the problem/concern,
but hopefully this answers any questions remaining.

As the documentation describes, there are roughly 2050 pages of
non-pageable structures for 1GB of vdisk space. On older releases,
z/VM 5.3, these structures were restricted below 2GB.  The first
check is to ensure these will not consume more that 1/4 of DPA.
For current releases, I believe the easiest approximation of this
is to take all the frames above 2GB add the Pageable Frames below
2GB (see QUERY FRAMES), subtract RealFreeStorage, LockedRS,
Nucleus/Prefix, Trace, Other (also from QUERY FRAMES).
As the documentation describes, take 25% of that and divide by
2050. This gives the DPA bounded limit in GBs of vdisk space.

For the paging space, it is just like the documentation describes.
The easiest approach is do a QUERY ALLOC PAGE. Take the sum
of the page slots (not counting any Drained or Draining volumes.)
Take 25% of this value divide by 262144 (page slots in a GB) to
get the page space bounded limit.

Use the minimum of those two values.

Perhaps I am too close to the subject to judge the clarity
of the documentation. If you feel there is need for
improvement, reader's comments can be submitted on the web:

CAVMEN Meeting on Thursday, April 22, 2010

[Chicago Area VM (and Linux) Enthusiasts]

The second quarter meeting of the Chicago Area VM (and Linux) 
Enthusiasts will be held on Thursday, April 22, 2010.


ROAD CONSTRUCTION UPDATE:

The road construction projects in the Hewitt Associates area still 
have not been completed.  However, the only currently active 
construction in the area is at Milwaukee Avenue (Route 21) and Half 
Day Road (Route 22).  It is not causing major delays.


If the situation changes, we will update this section prior to 
sending additional notices in the coming weeks.



--


Meeting Location:

This quarter's meeting will be held at the Hewitt Associates 'East 
Campus' located at 100 Half Day Road, in Lincolnshire, IL. We will 
meet in Conference Room 100-M3, in Building 100, just off the cafeteria.


If you have not attended a meeting at this location before, or you 
are not familiar with the area, 
Click here for 
additional information on directions, maps, lodging and dining.

Attendance:

We would like to request a count of expected attendees by the Monday 
before the meeting, so that we may plan appropriately for arranging 
the facilities, and for refreshments and lunch, should one of the 
vendors wish to provide them. If you are planning to attend, PLEASE 
send an E-Mail by that date to 
cav...@comcast.net with a subject line of 
"Meeting Attendance".


This is meant to be a facilities planning aid and should not be 
interpreted as a registration requirement. If you suddenly become 
available at the last minute, please feel free to attend even if you 
have not responded.


Thank you in advance for your cooperation in this matter.

Meeting Agenda:

9:00 AM Eliminating the Barriers: Bringing z/VM Administration to the 
21st Century


The skills needed to administer a z/VM system are typically acquired 
over a period of many years. Bringing new people in to the fold can 
be challenging when all they think about when they hear 'mainframe' 
is green screen. Experienced admins from other platforms might be 
turned away by having to learn yet another set of commands and a 
terminal interface. Other virtualization platforms compete for mind 
share via sexy GUIs.


This presentation will slide-show/demo (depending upon network 
availability) a project that provides cloud enablement for z/VM and 
will allow the administration of a z/VM system from a web browser.


The speaker will be Rich Smrcina of Velocity Software.

10:30 AMCoffee Break

11:00 AMManaging Linux on z/VM

Managing Linux on the mainframe requires capacity planning, 
performance analysis, chargeback and operational support. This 
presentation discusses technologies that can be used to accomplish it 
all effectively.


The speaker will be Rich Smrcina of Velocity Software.

12:30 PMLunch Break

1:45 PM Administration and Vendor Announcements

2:00 PM Linux on z Update

The speaker will present a brief update of recent developments in the 
Linux under z/VM area.


The speaker will be Paul Augustyniak of the IBM Corporation.

2:30 PM SUSE Linux Enterprise 11 SP1 - Ready to Roll Out

Find out just what is cooking in the upcoming release of SLES 11 SP1. 
We'll spend some focused time on what is new, updated, and supported. 
Of course, the special emphasis will be on System z.


The speaker will be Don Vosburg of Novell, Inc.

3:30 PM Coffee Break and Prize Drawing

3:45 PM Run your ASP.NET applications on System z: A Closer 
look at how Mono on SUSE Linux Enterprise 11 can free you to fly


We will look at the architecture of running Mono - the Linux 
implementation of .NET. Then we will discuss some real-life 
situations where you might consider deploying these application 
servers on SLES 11 for System z, and hear about what others have done.


The speaker will be Don Vosburg of Novell, Inc.

4:45 PM Free-for-All

Members will attempt to answer any reasonable VM or hardware related 
questions. If you are having a problem and want to find out if others 
are experiencing it, or you are installing new hardware or software 
and want to find out what types of problems others have experienced, 
here is the place to find out.


Members are encouraged to bring ideas for future presentations and 
speakers to this meeting.


--

Please check the WEB site for Map and Directions:
http://cavmen.home.comcast.net

In addition, you will also find extensive information available on 
dining and lodging in the Hewitt Associates area.


Additional information about the CAVMEN group, and other VM related 
items of interest are available on our web site.


There is no charge for admission to meetings.

Meeting attendance is open to anyone, and advance registration is not required.

I look forward to seeing all of you at the meeting.
