Responses to "Moving on" posts I remember mostly are of the "good luck,
it's been nice knowing you" kind.

I think Mark was expressing concern about "jobs available" notices, not
"work wanted."

ANZ Bank (anz.com.au) has just announced its sending lots of jobs tO
India. I'm an ANZ customer. I'm wondering what that implies for my
privacy, Indian laws are not Australian laws. I'm sure they're not as
good as Australian laws, and enforcement is problematic. I don't like
the idea of most confidential information about me leaving our shores.

What happens when there's an information leak in India? Does Australian
law apply? I suspect not.

If any employers are thinking sending IT work, these are concerns that
need to be addressed.

Although I certainly appreciate the concept of LinkedIn and what it has to

just don't care for that sort of social networking.  There could be other

MEMO postings are a hold over from before Al Gore invented the internet and are 
very
relevant to the audience of the list.

was not arbitrary, tracing back to MEMO MOVING-ON on the old VMSHARE site (for

I hope you mean you are looking at installing Linux on System z.
z/OS is an operating system. :-)

Most customers today install under z/VM so that is where most of
the documentation points you to. However, there a few older
Redbooks on the subject. Just search at http://ibm.com/redbooks
for "linux and zseries". Most of these date from the 2001-2004,

Re: starting 'at the begining' to install linux on z/os

2009-03-13 Thread Hall, Ken (GTS)
That assumes you have access to the HMC in the first place.  I don't
know what his environment is like, but I'm 1000 miles away from the data
center, and in any case, they don't allow anyone NEAR the HMC during
business hours.

Setting up VM initially might take a little longer (like one day if you
know what you're doing), but the benefits come back quickly.  

The one thing I did forget to mention before is that if you're going to
set up an LPAR, it helps to carve out a subset of DASD defined only to
that LPAR, and try to standardize the addresses.  When you're dealing
with real addresses, you can't move them around as easily as you can
with virtual minidisks, and Linux will scan ALL available DASD devices
on IPL.

Installing Debian from the HMC cupholder was pretty easy; I got it done
in an afternoon.  What's more time-consuming is getting the LPAR
defined, with the DASD device addresses properly isolated from your
production system(s).  Took me several iterations with HCD to get it
right, and much longer than it took to install Debian itself.  (HCD and
I don't get along all that well.)

There might be some downtime associated with creating a new LPAR,
depending on your dynamic-reconfiguration-fu and whether you've got
spare memory to carve out.

I'm not VM-literate, so it took me less time to build the LPAR than it
would have taken me to install and learn VM.  (Not to mention that I'd
have had to convince someone to pay for it.)  DB has a litany of reasons
for using z/VM in your Linux farm, and you should generally listen to
anything he says... but for my modest purposes a single little LPAR
works just fine.

Your best bet will be to define a guest LAN inside VM, tell the rest

as your router for your Linux guests.

There have been a few job postings in the past, but not a lot.  Each time it 
has caused some of the list members some consternation,because their employers 
forbid them to be subscribed (from their work email) to any mailing list where 
job postings are made, no matter if that's not the main purpose of the list.  
In some cases, it's cause for termination for them.

So, while it's not actually prohibited by anyone, it's also not actively 
encouraged.  There is a no-cost job posting page on Velocity Software's web 
site.  Other than that, I would only say going through one of the commercial 
sites such as dice.com, monster.com, etc. might be your best bet.  Over the 
last year or so, I have seen a number of mainframe Linux and z/VM jobs pop up 
there.

Although there hasn't been too many people that have announced layoffs, your 
last option I would say would be looking through the archives of this list and 
IBMVM.  We had one of our members recently get laid off from his job, and he's 
looking for z/VM and Linux employment in the Minneapolis/St. Paul area.

Re: SUSE 9 on Mupltiprise 3000

2009-03-13 Thread Rich Smrcina

Hey in there...

There are a couple of ways you can do this.

If your Bustech MAN has additional LCS devices defined, DEDICATE a couple of 
them to the
Linux virtual machine and use them in the network setup portion of the Linux 
installation.

Set up a Guest LAN under VM and route it through your VM TCP/IP stack.  That 
will
require some routing finesse with your outboard routers and systems, but it is 
certainly
doable.  This will require a separate subnet for the Linux virtual machines 
that use the
Guest LAN.

The CTC to VM idea is really clunky and will quickly become difficult to 
maintain.

Hi, Steve,

Welcome to the mailing list.  Now that everyone's been pedantic and told you 
that z/OS <> mainframe, take a look at http://linuxvm.org/redbooks.html .  The 
second book in that list, " Linux for IBM eServer zSeries and S/390: 
Distributions" is quite old at this point, but it does describe how to do 
installations in an LPAR.  Don't look to the details of each step to be 
correct, but the overall flow is going to be similar:
- Set up a working NFS, FTP, HTTP, or SMB server that your z9 can reach over 
the network
- IPL from tape or the DVD
- Get a working network connection defined
- Access the installation server
- Once the installation routines are up and running, SSH in (or use VNC) to 
actually start the install process
- At the end of phase 1, reboot the system and SSH in again to complete the 
configuration.

I also strongly recommend you take a look at 
http://linuxvm.org/Present/SHARE112/S9233mp.pdf , "Linux Installation 
Planning."  The first slide in there talks about the need to get all the other 
groups in your organization involved up front.  If you don't, you're going to 
have a hard time succeeding.  The last few slides lay out all the data you'll 
need _before_ you start the first IPL from tape.

As others have said, getting z/VM installed first would be a really good idea.  
IBM is usually willing to loan you the hardware and software you'll need to be 
happy with your R&D results.  Trying to run Linux in the white space left over 
from z/OS is usually not sufficient, and performance is likely to stink.  If 
you do go with z/VM, there is a good "Virtualization Cookbook" on the IBM 
Redbooks site that will walk you through the process of getting both z/VM and 
Linux installed: http://www.redbooks.ibm.com/abstracts/sg247493.html

SUSE 9 on Mupltiprise 3000

2009-03-13 Thread Fridrich, John
Hey out there...

Has anyone installed SUSE 9 under z/VM 4.4 on a Multiprise 3000 (7060)???
I have the boot-strap installed and working up to the network part... Can't 
ping outside the machine so I can't FTP the install back in.
Not sure how to configure... or what network interface to use... The 7060 is an 
odd machine...
I've tried the emulated ethernet cards, CTC to VM's IP stack, and directly to 
the BUSTECH MAN (ESCON attached LCS device) that I run all of my IP traffic 
through (3270 sessions and VSE's IP stack)...
All with no luck... $...@...

Installing Debian from the HMC cupholder was pretty easy; I got it done
in an afternoon.  What's more time-consuming is getting the LPAR
defined, with the DASD device addresses properly isolated from your
production system(s).  Took me several iterations with HCD to get it
right, and much longer than it took to install Debian itself.  (HCD and
I don't get along all that well.)

There might be some downtime associated with creating a new LPAR,
depending on your dynamic-reconfiguration-fu and whether you've got
spare memory to carve out.

I'm not VM-literate, so it took me less time to build the LPAR than it
would have taken me to install and learn VM.  (Not to mention that I'd
have had to convince someone to pay for it.)  DB has a litany of reasons
for using z/VM in your Linux farm, and you should generally listen to
anything he says... but for my modest purposes a single little LPAR
works just fine.

If you want to be conservative, assume "used GigaHertz" will be the same (_not_ 
"available GigaHertz), and any CPU that's driving I/O on the AIX box will turn 
into extra capacity on System z.  (This can be huge, if AIX is doing lots of 
I/O.)  Many people are able to achieve real storage over commit rates of up to 
1.5.  I would assume lower, again for the sake of being conservative.

But, the best way is to measure an AIX system, move the workload, and then 
measure again to see how _your_ workload acts.  Do this a few times and you 
should start to get a feel for how things are translating.

Ursula,

That would be really good.  While you're at it, could you perhaps also
talk about cause codes 0x04, 0x08, and 0x17?  Those have shown up in the
past, although not nearly as often as others.

Server sizing from AIX to z/Linux - Rules of thumb?

2009-03-13 Thread Jim Moling
Wondering if anyone has some rules-of-thumb for sizing a z/Linux virtual
server for AIX-based workloads, specifically CPU & memory.
All I am looking for are rough guidelines that can be used as a starting
point to estimate resources for moving a workload from a mid-tier platform
(AIX) to a mainframe virtual Linux server.
For example, we have AIX Server based applications that use a 3-tier
architecture that consists of:

1) Web Server - 2 CPU, 2 GB RAM
2) App Server - 4 CPU, 8 GB RAM
3) DB Server - 4 CPU's, 16 GB RAM, 100 GB Storage

I realize that it ultimately depends on just how busy a server is in order
to determine resource requirements with any degree of accuracy, and
explained as much to those that asked me about this, and being short of
any empirical data at this point, was hoping that others may have derived
some basic guidelines based on their experience. We're looking at
potentially moving hundreds of AIX servers onto mainframe-based Linux
servers, so trying to get a handle on just what that will mean in terms of
resources. I figure the disk-based requirements would be pretty much
Gig-for-Gig, but not sure how to factor AIX CPU's to z10 IFL's and the
scaling factors going from AIX RAM to central storage. I humbly ask for
any help towards getting a better handle on this, which would be greatly
appreciated.

Thanks, Jim Moling

That's totally arbitrary, and defined in SYSTEM CONFIG.  Don't allow too much, 
because if Linux winds up using it all, it can really hurt your system.

Re: starting 'at the begining' to install linux on z/os

2009-03-13 Thread Hall, Ken (GTS)
First of all, you don't install Linux on zOS, you install it on either
the zSeries processor, or under zVM.  About the only part you might need
zOS for is to create an IPL tape if you want to install in an LPAR.

This isn't recommended though, and I think a lot of folks on this list
will echo that, particularly Mr. Boyes, who has a lot of experience with
this.  The installation on bare metal is tricky (as those of us who have
installed under Hercules have found) and requires access to the HMC for
possibly many sessions to get things right so it will come up and
install.  zVM gives you a much more manageable environment to work
under, and if you talk to IBM, they're usually more than willing to help
with getting it going.  The learning curve for getting zVM installed has
some bumps, but following the one-page instructions, you can have a
basic system up in a couple of hours.

Another option, if you're determined to go the LPAR route would be to
try it out on your desktop under Hercules (the zSeries emulator), and
once you have the process down, go back to the real thing.

 Hello,

  I am at the beginning of installing Linux on z/os. I thinking just in
an Lpar or two for now, z/vm later. This is an R&D project just to get
it up and running. I have a Z9 and a copy of SUSE. Now what? What would
be the best redbook or manual?

Thanks,

Re: Getting Gnome to behave

2009-03-13 Thread Mauro Souza
Your problem isn't with Gnome... You are using twm as your default window
manager... You can change it (as people already said) in your
${HOME}/.vnc/xstartup. Or you could start the service (service, not program)
vncserver for the entire box. Connecting to it will bring you to a login
screen, rather to your crude, barebone desktop...
If I am not mistaken, you can change twm for gnome-wm in your xstartup file
to bring up gnome.

starting 'at the begining' to install linux on z/os

2009-03-13 Thread Gear, Steven
 Hello,

  I am at the beginning of installing Linux on z/os. I thinking just in an Lpar 
or two for now, z/vm later. This is an R&D project just to get it up and 
running. I have a Z9 and a copy of SUSE. Now what? What would be the best 
redbook or manual?

Thanks, 
  steve

If you have the postfix package installed (and you almost certainly do), there 
shouldn't be anything you need to do except start sending emails.

chkconfig --list postfix
postfix   0:off  1:off  2:off  3:on   4:off  5:on   6:off

rcpostfix status
Checking for service Postfix: running

netstat -ln | grep :25
tcp0  0 127.0.0.1:250.0.0.0:*   LISTEN

You may have to edit /etc/postfix/main.cf to specify the "relayhost =" 
parameter, if there's a specific relay host that your organization wants 
internal email senders to use.

I think this subject has been broached here before, but for the life of me I 
can't find it. My wife complains I don't look hard enough so please be gentle 
in your criticism.
Problem:I want to set up email to just a few select users on my system. I have 
some displays I want to take then email them to mine/their outlook accounts.
I am unsure how to do this even where to start, so please start slow, speak in 
small words, and be kind.

Cause code 0xf6 has been caught in qeth recently:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=fc9c24603c4b93d84160e14c0a98a754d4328d15

I am going to discuss with z/VM development whether qeth should catch
cause code 0x4e as well.
