I have found various threads about using NED on a 3270 console to zLinux and I
thought this was a good idea. I read the 3270 HOWTO on linuxvm.org but it
seemed no longer relevant to recent kernels; I am running 2.6.26. I have no
tub3270 module so there is nothing under /proc/tty/drivers and so

I fully agree about the need for a performance monitor, but that is

Whenever I hear about z/VM guests
This reminds me
We have an obscure z/VM partition with a few linux guests on it that
don't require a lot of babysitting, as they are not really production
applications. A person in another group requested a new virtual machine
to install the latest RHEL, so I gave it to him. Later on I asked
I found it and it ran OK. The password is required for the web interface
only. The Windows client does not ask for it. Thanks to all!!!

Ok, Lea, i know i shouldn't do email before coffee. It's just problems like this have
caused many installations to say "We tried linux, had performance problems nobody could
fix so we abandoned the project". So see the CONFIGuration guidelines on our website, not
as good as going to class, but

OK Barton, I fixed it. Calm down.
My company does not believe in classes. I had a Windows Server class in 1997 or
1998 and am working VM/Linux with no classes.

here is what I use for a linux system
LDUBUF : Q1=200% Q2=200% Q3=200%
STORBUF: Q1=300% Q2=200% Q3=200%
It is probably your LDUBUF for Q3 users that is causing it.Change that
one 1st and see how it does.

Has anyone installed either of these products on z/Linux (SUSE)? If so,
can you provide some detailed instructions to do so? I am assuming that
I will have to install from source and have not done that before.

I just tried the web interface and it responded to 5801, but I had to
give it ROOT password to get a login screen. Can I set the VMC password
separately from the ROOT password?
I am sorry for all my questions, I am not trained on Linux and am doing
OJT.

I was using a W2000 client and VNC did not respond to :1 or :2, but it
did respond on :5901. The doc said 5801 and did not state browser only.

Look back in the performance toolkit data and see if an eligible list formed
around the time LX004 hung up. You may need to add more paging exposures
and/or adjust your SRM.

You might want to take a look at your Query SRM command. Check and see
if your LDUBUF and STORBUF have settings below 100%. If you are still
using the defaults it can lock Q3 users out from doing any work.
