There's a redpaper that talks about this. See:
Securing Linux for zSeries with a Central z/OS LDAP Server
You might also want to check out the ABC's redbooks (which ever one
deals with RACF and security).
Mark,
Is your picture from the Orlando presentation still valid when virtualization
is factored in? The discrete system view factors in massive underutilization to
be able to run on so few IFLs. The general thinking in my company is that
VMware is a lot simpler route to attack that.

Red Hat 7.1 and 7.2 were not commercial product offerings from Red Hat.
Red Hat introduced its commercial offering with Red Hat Enterprise Linux
2.1, which was not offered on the s390. So I believe that there is
confusion here between what is Red Hat Enterprise Linux and what is Linux.

It IS a seriously misinformed person.
We've been running Oracle RDBMS for several years now in a z/VM
environment. No issues.

Slide 9 has information on Oklahoma Department of human services. It's
a little dated, but it's what we experienced back then.

Not what the Oracle rep (thought they were) was talking about. Works great
is not the same as
PMFJI
On my smaller Oracle 10g R2, under SLES 10 SP2, with OEM running, I've been
able to get the SGA down to 140 MB, with PGA of 16 MB. This can run in a vsize
of 600 MB with dual prioritized vdisk for swapping.
There are a lot of smaller applications, that don't need GB databases G. And
I would second that.

Come on now, haven't you heard the Mainframe is dead? ;)
While I certainly can't speak for entire companies, I'm aware not aware
of any such efforts.

No support issues. Actually we had more support issues starting up with
IBM than Oracle.

Linux on the mainframe has given z/VM new life. This presentation explores
the evolution of CA¹s system management solutions for z/VM as invaluable
tools for securing and managing z/VM environments. An overview of
I am starting to get guests dropping off into E3. Here is what it looks like:

VSWCTRL1 Q0 PS 0086/0025 SWPLT01 Q0 PS 00015174/00015100
SWPLT02 Q0 PS
You're on the right track.
I'd try storbuf 300 300 300 for immediate relief from the E3.
But you are still overcommitted by a lot, more real storage (or smaller,
fewer servers) is in order.
With z/VM 5.4 you can add storage dynamically. Course, that assumes
you've got some sitting in the z9
STORBUF is the answer, the default is broken as designed. See first,
http://velocitysoftware.com/faq.html;, and then
http://velocitysoftware.com/present/CONFIG/;
for configuration guidelines, that will help you avoid other such unavoidable
issues.

another question - did you set those 2 largish machines with QUICKDSP ON?
If yes, why? In general I am not a huge fan of QUICKDSP, it bypasses some
important scheduler decisions, somewhat defeating
the concept of fair share scheduling.

I try and keep quickdsp off as much as possible as well. Many fruitless
arguments have ensued. It may be overkill to have it set 'ON' on a test LPAR
but swplt01 is a firewall, swplt05 is a WAS portal. It is 'on'

As David indicated, QUICKDSP is a very big stick that has specific uses. Once

implement Barton's suggestion, you may want to handle prioritizing individual
virtual
machines with SET SHARE. Be careful there as well, the relative numbers are
just that,
relative to each other.
