Does anyone have recommendations for a scheduling package that can
control processes on zLinux and interact with our zOS based CA-7 scheduler?

Have you asked CA? We have something called CA-7 CPS which schedules
work from CA-7 on z/OS to various open system servers. I don't know
if
they have a z/Linux client.
Or you could just use CA7 and add NJE to your Linuxen or other open
systems boxen. CA7 natively understands submitting jobs
I'm trying to find the CP command which will show when the last time the system
was IPL'ed.
I don't thing 'ind user system' shows the whole story.
Thanks.

I don't know. I did find a parameter that I can put in the DTCPARMS file
but the manual doesn't explain much about it. The operand is a 'B' (w/o
the quotes). It sets the number of disk blocks (disk blocks for what?)
The default is 256.

Is there a maximum file size VMNFS can handle? I'm doing a file copy
and get stopped at 2gig. This is when a linux guest is writing to the
NFS file.
Regarding the VMNFS command, there is an operand called 'B' (w/o the

Hi,
Looking to find some where on one of the performance toolkit screen
something that will show me the overall CPU utilization and Storage
utilization.
We are trying to determine if another IFL is needed or more real storage
on the box.
Thanks
Brian
try screen 35 for a real time minute by minute breakdown of some good values
for CPU, xstore and paging.
For real storage utilization I'd be more concerned with expanded storage
utilization, volume of transfer to/from xstore, and paging bandwidth and
utilization. Main storage utilization
A lot to look at on the screens, but option #1 CPU load and trans. and
option #2 Storage utilization on the PERFSVM green screen should tell
you most of what you need to know to give you some idea.

Thanks everyone,
Under option #2 it shows a Storage utilization of 89% and through CMS if
I issue the command q alloc page I see that over 3 3390 mod 3's I have a
utilization of 73%.
So if I were to summarize this out of 8gb real storage assigned to the
lpar performance toolkit is showing
You might consider adding six more 3390-3 PAGE volumes.

double your paging capacity sooner rather than later - the 73% page space

Do you have any expanded storage configured?
The 89% main storage utilization doesn't really mean all that much

From: The IBM z/VM Operating System on behalf
Storage utilization isn't really an interesting number. Page space
utilization is and as Jim indicates, you're paging space is under
allocated. The ROT is 50%.
Does any of the history screens that David pointed you to show that you
did any paging? If not, then you don't have a storage
First, get that 73% number to 50% ASAP.

Hello All
I'm attempting to connect a TCPIP stack and some LINUX guests to a
VSWITCH using 802.1Q trunking, and the network administrator sent me the
following VLAN info as he configured it on the real switch:
Attached are the IP addresses you requested. I will put the trunk in
place on core
Nobody told why page space should not be filled too much:
CP uses block paging, that is it writes multiple pages out with one
I/O, the number of pages varies. After a while, the paging areas get
fragmented, and CP an have a hard time to find a free spot to store
the blocks of pages that it has
Thanks again,
I will add a few more paging packs this evening. Is it a fair
assumption that if I'm using 73% of the 3 page packs most of the real
memory is 100% fully utilized?
I have 512mb allocated to expanded storage.

Yes, it would be full of stuff so VM has moved some stuff out.
Whether you can tune that down is another story.
(oversized virtual machines will lead to linux stuffing it with stuff
you probably don't need in memory anyway).

You don't _have_ to wait for evening. CP permits you to CPFMTXA spare
DASD, and add them on the fly.
Whole DASD volumes are recommended for page space. Best practices
includes allocating page packs as:
PERM 0 0
PAGE 1 END
(Actually, it's safest to always reserve cylinder zero on all whole VM
Assuming that you have free slots in the CP_Owned list.
It is documented that CP understands and will preserve that part of
cylinder 0 if a volume is allocated from 0-nnn as a PAGE or SPOL pack
and that doing so is OK. Do you know of an actual problem (in the last
15 years) caused by allocating 0
I have never seen a problem with CP stepping on the Label. I have
stepped on it myself and seen other inexperienced people step on it.
That is why I always allocate cylinder zero of a VM volume as perm and
allocate a one cylinder minidisk owned by VMDASD there. That is the
best practices
That is why I said, Granted, for all other devices, it is best to
allocate cylinder 0 as perm. There you have a guarantee that the volume
label will get wiped out if that cylinder is included in a user
minidisk.
If you are trying to wipe out the label on an active page or spool
volume that is so
Yes, I also have placeholders for $PAGE$, $SPOOL$, $TDISK$, $DIRECT$ and
MVSDASD. But that is a different best practices item.

Taken together, the allocation as a spool or page extent an the
inclusion in a defined MDISK extent is pretty strong protection and
makes the separate allocation of cylinder 0 somewhat redundant. But if
you want to do that, it does not prohibit you from allocating the space
as PAGE or SPOL in
Correct, the allocation of a minidisk does not affect the volume label,
the allocation bitmap or it use by CP for paging, spooling, online
directory or warmstart. The allocation of a minidisk helps keep the the
bookkeeping straight. It is hard for DIRMAP or DISKMAP to tell my
replacement where
Every site that I have been associated with has operated under the premise
that, with the exception of full pack minidisks, cylinder zero (0) is ALWAYS
allocated PERM, and a one (1) cylinder reserved space minidisk is placed in
the directory for each volume in recognition of that fact.
