You will need a separate SSL server for each stack.  If you want, you can 
try to share the certificate database via NFS or SAMBA, mounting it r/o on 
all but one server.  I can't vouch for the correct operation of the 
servers, however, as they were not designed or tested to that purpose.

Message DMT083E should be issued on two lines such as:

DMTTNE083E Socket error on link GDLVML00 request=Recv
DMTTNE083E return code=- 1 error number=54 (Connection reset by peer)

I cannot think of any parameter which would cause only line one to

and we will further investigate why the message is not coming out in
two lines.

Thank you Alan for the response.
 
So are you saying that since I cannot specify a passiveport range in
z/VM 3.1 (TCP/IP) I cannot
resolve the filelist problem while using z/VM 3.1 (TCP/IP)? If I do not
know which port TCP/IP will use
for datatransfer I guess I do not know which port to tell our ISP to

Their explanation does make sense, yes, but z/VM 3.1 doesn't have
passive 
FTP support.  With passive FTP, the server will tell the client what
port 
number to connect to for data transfer (e.g. file list).  The firewall

watches for that disclosure and it opens up the indicated port.

FYI, z/VM 5.3 adds a PassivePortRange statement to enable you to open
up a 
pre-arranged hole in the firewall, allowing passive FTP to work even
when 
the control connection is encrypted.

Well, I'm no ace at this, but your definitions look strange to me. I

The simulation support is useful to determine what percentage of a z/OS 
workload would be placed on a zIIP or zAAP.  Once you find that you are 
running out of headroom, you may decide that a sufficiently large 
percentage of the z/OS cycles are running on zIIPs or zAAPs that you may 
decide the next CPU to add is a real zIPP/zAAP (or share the one we had.)

You're right, you should drain *all* the spool volumes to prevent the 
creation of new files while you're backing up the spool.  :-)

So I think I'd choose SPFPACK.  It's a lot easier to deal with open spool

Re: z/VM 3.1 FTP

Please see the below explanation from our ISP 
What I am trying to do is change the default listen port (ftp) of 21 to

When our ISP opens the firewall  I can connect using the new port

Thank you...Neil
=explanation from
ISP=

In Standard FTP
When a client starts an FTP connection, It opens a standard TCP channel
from one of its high order port 21 on the server.  This channel is
called the command channel.  When the client requests data from the
server, it tells the server to send the data to a specified higher order
port.  The server acknowledges the request and initiates a connection
from its own port 20 to the high-order port that the client requested. 
This channel is called the data channel
In Passive FTP
In this mode the command channel works in the same way as in a standard
FTP connection, but the data channel setup works differently.  When the
client uses a non-standard FTP port and requests data from the server,
it asks the server whether it accepts Passive FTP (PFTP) connections. 
If the server accepts PFTP connections, it sends the client a high-order
port number to use for the data channel.  The client then initiates the
data connection from its own high-order port to the port that the server
sent.
So basically I was trying to say unlike in Standard ftp mode where the
server does the data communication on port 20, in Passive ftp  mode the
Client comes up with a higher port number to talk to the server

Hi Neil,
 
There is no configuration file setting that I know of. Instead, use the

Performance Toolkit FCXTREND file

[RPN01]

We¹ve been running the Performance Toolkit since October, and the 
FCXTREND file is getting a bit large. I wrote a pipeline to break this file
down into monthly segments, and thought I had a way of using them via the
FCXSUM command, documented in the manual... But once I got to that point,
there appears to not be a FCXSUM command in the actual product.

Is there another way to boil down the FCXTREND file into data that is usable
by the product for reporting, or is it strictly for writing your own reports
against? Should this file just be cleaned up on a regular basis if you¹re
not using it for your own reporting? Is there anything out there that would
use the data to produce some trend reports for the system?

If not, then I just spent a day writing a slick exec that will give me
monthly files to delete instead of the one big file  :-(

Subject: Re: LPAR weightings

 

You **do** have to worry about how many CPs an LPAR has. Not always, but
if you know how it works, you can avoid the pitfalls, surely when you
start using capping.  My customer learned it the hard way on a 9672.  We
had a partition capped at 60%, a lot.  But, it had 6 engines, so each
engine was capped at 10%.  DB2/VM had a very hard time: it was able to
consume a bit more than this 10% but not enough. 
If all your important processes are MP capable, I guess you have to
worry less.  A UP process though may have a hard time to consume enough
when the weight distributed over the logical processors is low.
BTW, VM's dispatcher works the same way. 

2007/3/13, Curren, Pat J. <[EMAIL PROTECTED]>:

I have used 1,000 as the total of the weights for years now with
excellent results.  Just figure out how much of the machine you want
your production to take and give it that much weight, ie: if you want
production to have 60% of the machine give it 600 as a weighting factor 
and give test 400 for a total of 1,000.

You don't have to worry about how many CPs an LPAR has.  The number of
logical CPs determines the maximum amount of MIPS you can use.
For example if you have 5 logical CPs and a weight of 600/1000, then the

LPAR dispatcher will give you 60% of 5 physical CPs.  You can use up to
100% of 5 CPs if nobody else is using them.

The messages above are consecutive in the console log, with no
intervening messages that were deleted. Following this, the z/OS system
immediately signs on again. 

HELP for message DMTTNE083E indicates that a return code gives further
documentation. What return code? It certainly is not in the messages.
The format of the message is different than the format shown in the HELP
file. I know, this is a matter for an RCF. That will come later as I
have a more immediate problem, the one of solving the riddle of what
actually happened and stabilizing the link..  

The RSCS link was defined using a command like "DEFINE MVSG TYPE TCPNJE
PARM HOST=10.245.46.89" followed by a START MVSG command. Files can be
sent back and forth across the link. The messages only seem to occur
when there is no activity for a period that probably matches a timeout
value; however, I see nothing in the documents about specifying or
altering a timeout for the RSCS end of the link. 

It may be of interest that we have a TCPNJE link between two of our VM
systems. It has no such problem, which tends to make me believe that a
timeout interval, if there is one, must be an MVS thingy.

How do I find out what is happening? If it is a timeout, what do I do to
prevent it from happening?

Re: LPAR weightings

[Kris Buelens]

You **do** have to worry about how many CPs an LPAR has. Not always, but if
you know how it works, you can avoid the pitfalls, surely when you start
using capping.  My customer learned it the hard way on a 9672.  We had a
partition capped at 60%, a lot.  But, it had 6 engines, so each engine was
capped at 10%.  DB2/VM had a very hard time: it was able to consume a bit
more than this 10% but not enough.
If all your important processes are MP capable, I guess you have to worry
less.  A UP process though may have a hard time to consume enough when the
weight distributed over the logical processors is low.
BTW, VM's dispatcher works the same way.

2007/3/13, Curren, Pat J. <[EMAIL PROTECTED]>:


I have used 1,000 as the total of the weights for years now with
excellent results.  Just figure out how much of the machine you want
your production to take and give it that much weight, ie: if you want
production to have 60% of the machine give it 600 as a weighting factor
and give test 400 for a total of 1,000.

You don't have to worry about how many CPs an LPAR has.  The number of
logical CPs determines the maximum amount of MIPS you can use.
For example if you have 5 logical CPs and a weight of 600/1000, then the
LPAR dispatcher will give you 60% of 5 physical CPs.  You can use up to
100% of 5 CPs if nobody else is using them.

You don't. z/OS does. z/OS is the only thing that can manipulate a zAAP.

That is the DFSMS/VM RMS APAR that allows for MULTIUSER attach support.
This will allow you to use request an RMS operation without having

request a library mount for a user ID and not have it detached from

z/VM - z9 and zAAP

[Mark Pace]

I have this new z9.  In this z9 I have a regular CP, a IFL and a zAAP.  I
had no problem defining an LPAR with the IFL and running z/VM and Linux.  I
created and LPAR with a regular CP running z/OS 1.7.   Now I have defined an
LPAR with a regular CP, sharing the one CP, and defined the zAAP.

In that LPAR z/VM does not show the zAAP.  I assume that I should be able to
see with Q PROCESSOR.
q processor
PROCESSOR 00 MASTER
Ready; T=0.01/0.01 13:12:11

When I look on the HMC I see that all the processors are defined to the CPC
and that they are Active.  But when I look at the LPAR I see the processors,
but the zAAP is Stopped.   I can not figure out how to "start" the zAAP.
The Activate Icon doesn't do it, and the Start Icon in the CP configuration
area doesn't do it.

How do I start the zAAP?

That is the DFSMS/VM RMS APAR that allows for MULTIUSER attach support.
This will allow you to use request an RMS operation without having
the device detached from another user ID.   For example, you can
request a library mount for a user ID and not have it detached from
that ID to satisfy the mount.

If IBM's High Level Assembler (admittedly a great assembler) is too
expensive for your pocketbook, look at the IBM Program Product Matrix
at:
http://www.vm.ibm.com/vendor/vend520.html
for the non-IBM product: Dignus Systems/ASM, found at: 
http://www.dignus.com/dasm/

Word on the street is that a certain mainframe Operating System
developed and supported in New York State, somewhere *west* of Mecca
(more specifically west of Poughkeepsie) is written and supported using
Dignus's Systems/ASM.  But that's only rumor, I have no way of knowing
for sure.

At least it's worth looking into.

Re: LPAR weightings

[Curren, Pat J.]

I have used 1,000 as the total of the weights for years now with
excellent results.  Just figure out how much of the machine you want
your production to take and give it that much weight, ie: if you want
production to have 60% of the machine give it 600 as a weighting factor
and give test 400 for a total of 1,000.

You don't have to worry about how many CPs an LPAR has.  The number of
logical CPs determines the maximum amount of MIPS you can use. 
For example if you have 5 logical CPs and a weight of 600/1000, then the
LPAR dispatcher will give you 60% of 5 physical CPs.  You can use up to
100% of 5 CPs if nobody else is using them.

Thanks for your update. Yes, I should have mentioned that I was aware
that 
the number of assigned CPU's affects the weighting but, in our case,
this 
does not matter as all 8 CPU's are shared across all partitions.

Re: CKDSVRST program from IBM Downloads

[RPN01]

Actually, it isn't necessarily IBM's call for a lot of the packages listed
there. Many of these packages were written by customers using zVM, and they
have the right to decide how to distribute their intellectual property.

Generally, the submitter of the package is listed along with each package,
and you'd be free to write to them and request the source; demanding it
probably won't get you very far...

I know, (at least I think I know), that it is the relative value of the

However, I just wanted to make sure that the actual values are not
important in themselves.

The background to this is that the weighting of one system/partition has
grown to 910 so that we have little scope now to adjust relative weightings.

I proposed normalising these to a 1000 total, in which case our large
partition would have a weighting of 580. Would there be any disadvantage, in
terms of the way the LPAR scheduler works, of normalising to 100 total so
that our partitions had weightings of 58, 16, 22 etc.?

Re: CKDSVRST program from IBM Downloads

[Berry van Sleeuwen]

Hello Thomas,

I don't like to see any of them removed. The download directory comes wit
h 
a clear disclamer. Use at your own risk, IBM doesn't support any of the 

materials found there.

In our procedures we document the utility and the workaround when it 
doesn't work anymore. Usually it means we need to do a task manualy or 

using a different tool. Take PIPEDDR for instance. When it can't be used 

anymore we must fall back to the old tape DDR to move data from one VM to
 
another. But as long as it works we keep on using the PIPEDDR.

We also used MOVESEG some time ago. But after migrating to zVM it did not
 
work anymore. So we moved to using DCSSBKUP/DCSSRSAV from the CMS 
utilities. So we did have a workaround for this utility. And the CMS 
utilities are supported by IBM.

I agree that source codes could help us. But to remove a utility when 
someone leaves the mainframe world could mean we lose a lot of usefull 

utilities.

The same is true for other materials found on the web. Take the PIPELINE 

runtime library for instance. While it is not supported by IBM it does 

provide us with functionality we do not have with the IBM supplied 
materials. IBM even links to the materials from the downloads page. But 

once again, one must be aware of the risks and make sure some work around
 
does exist before using a utility.

Regards, Berry.

I use TRACKREAD/TRACKWRITE to copy and restore CKD content.
Yes, had to extract the usage from PIPEDDR. Yes, sadly,

I suppose the PIPEDDR adds some additional checks to protect your own

write your data to a tape with CMS Pipelines, and if you look at a few
of your CKDVRST tapes you can probably reverse engineer it and have

For copying local disks track by track the function is close to DDR
(but probably a bit easier to incorporate in an existing program).
With a FORMAT RECOMP you can have CMS fix up after copying to a larger

It would help if IBM released the source code to these programs when their

A couple of suggestions:

- have you looked at the Microsoft Virtual Desktop Manager (at
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx)
which allows you to have 4 desktops. Not brilliant but could be helpful

- how about using Linux instead where you can have multiple desktops?
Admittedly you have to switch between them which might not be ideal for y
ou

- an outboard tool such as AF/Remote which can work as a console controll
er
with multiple messages being fed into one screen (you'll need to do a bit
 of
work there)

IIRC, the gas plasma screens were in fact not allowed in many European
countries due to emissions from them. I used one in the UK and thought it

was pretty nifty though.
