sorry about the delay in responding
   try:  rpm -q --q '%{name}-%{version}-%{release}.%{arch}' \

and you should get the same result, if both are installed.
'arch' and 'epoch' are 'silent' in the customary RPM -q query
option by design, as they are to some degree 'latecomer'
features; as such there is a large universe of scripting which
would get VERY confused by a format change there.

See generally the long time RPM site, relocated to:

in light of recent changes in the hosting arrangements for the

Yes, I certainly agree.  In this case, it's actually a WAS jmsserver
instance that is trying to start the queue manager.  Using sudo, we
can get everything to start correctly, but there's still some
confusion.  If root is a member of multiple groups, and you issue an
"id" command from an rc script during boot, shouldn't you see root's
entire group membership?



Why? root's not logged in. HOME isn't set either.

I removed all the ISOs and the old sles9xsp3root and started from scratch,
cut new ISOs downloaded to zLinux instance and ran vanilla mksles9root.sh
(sans my symlink). I then removed and readded the installation source in
yast. All I see now is currently installed software :-(

Re: Pros/Cons of FCP connection DASD

2007-03-26 Thread Tom Duerbusch
Depending on the size of your shop, but money is a consideration in
smaller shops.

i.e.  You already have ficon attached dasd with twin ficon cards.

Now you need another pair of FCP cards (at how much per card), and FCP
attached dasd (lparing your current DS6800 orr DS8000, or a separate
dasd subsystem) and, what do you get?

Slightly better performance (is the performance increase worth the
cost?).
Another set of underutilized channels (depending on the size of your
shop and requirements)
DASD that can't be universally used (some OS and older releases may not
support FCP attached dasd)
What else can you do with the money?

Then, the other things that have already been mentioned, like lack of
good performance monitors and detail compared to standard dasd
subsystems.  I assume that the SANs have their version of flashcopy and
mirroring.

In other words, if you need the performance, go for it.  If you don't
need the performance, then I'm not sure I would step up to it.

In my setup, two years ago, we upgraded to an IBM z/890 with IBM
DS6800.  LPARing the DS6800 to a FCP side was a possibility.  I rejected
it due to the cost and little perceived benefit.  Today, I would make
the same decision here.  However, at the next processor/dasd upgrade
point, I would revisit the decision.  But my gut feeling of our
performance needs in the next two years, would steer me away from adding
FCP, at this time.

But, if the Open Systems group, wanted to replace their current SANs
and I was offered additional disk space on it, I would consider adding
the FCP ability instead of an upgrade to the DS6800.  Just depends on
how the cost numbers work out.  

End of ramble...

The cost of supporting two different DASD subsystems (ficon and fcp) is
a cost that has to be considered vs the cost of supporting a single,
slightly lower performance ficon DASD Subsystem.

We have migrated a significant portion of our Linux disk space to
FCP connections, and have been very pleased with the performance
and with the ease of setting up very large file systems.

I would note a few cautions:

1.We found that setting up FCP disk for the first time had a
fairly formidable learning curve. The mail I see on this list
suggests that our experience is not unusual.

2.We still have disks we have left on ECKD devices because our
current hot site contract does not include FCP disk for the
mainframe. Make sure your disaster recovery process can supply
FCP disks, or that you can convert back to ECKD at the recovery
site in an acceptable amount of time.

3.We have never tried to use an FCP disk as a boot device. I
gather that the internals of the FCP boot process are considerably
different than the internals of the traditonal mainframe boot
process. I don't know how diffictult it is to set up the newboot process.

Lionel, this is really too broad of a question to answer well.  At a very high 
level, SCSI disks are great for large volumes, a little harder to set up, give 
better performance (when things are working right), but the instrumentation for 
performance monitoring is nowhere near that for ECKD (when things aren't 
working right).

Re: Pros/Cons of FCP connection DASD

2007-03-26 Thread RPN01
The biggest point in favor of the 3390 style DASD is that the 3990
(emulated) takes care of the mirroring and multipathing for me, where the
FCP SAN disk is not mirrored or multipathed unless I do it myself in Linux.

You may gain some file transfer speed, but you pay for it in CPU.

Re: Pros/Cons of FCP connection DASD

2007-03-26 Thread Pieter Harder
In my view it depends on what you need:

- a few very large disks, go for FCP
FCP luns can't be suballocated (as far as I know), so wanting a lot of
small ones won't give you any fun with the storage admin.

- lots of small disks, go for old style ECKD
LVMing lots of ECKD disks to get a large allocation is cumbersome. But
it is no pain to get a lot of them. That's what the S390 boys have been
doing for ages.


Best regards,
Pieter Harder

By most criteria that people would employ, they truly aren't.  Just
because we know how great they can be doesn't mean there's an awful
lot
of them out there, compared to others.  From our perspective the fact
that there _has_ to be so many of them in the first place is part of
the
problem, but that doesn't change the facts.  And besides, I would hate
having to lug around a z9 BC when I go to conferences.  My laptop
running SLED10 is quite heavy enough.  Which means that the skew in
absolute numbers won't ever go away, regardless of the OSes involved.

I'm curious.  What happens if you do a "yast -i packagename" from the command 
line, where packagename is something you don't already have installed?

I removed all the ISOs and the old sles9xsp3root and started from scratch,
cut new ISOs downloaded to zLinux instance and ran vanilla mksles9root.sh
(sans my symlink). I then removed and readded the installation source in
yast. All I see now is currently installed software :-(

I have also tried NFS, HTTP and Local Directory - all with the same

I used this (with a little mod to only show exceptions) - no invalid
