Hi, and good morning :)

I'll read all post after my previous, but first of all.. telnet cant be a
good way for me because i can login only with logon by, and "help telnet"
dont tell me any possibility for VM like logonby connection...

In this case, from a privileged id, 
   CP SET SECUSER otheruser *

This will let you watch AND interact (using the CP SEND command) with 
another userid.  If you only want to watch the userid, use CP SET OBSERVER 
instead.

The previous reference to "SCIF" (Secondary Console Image Facility) is the 
same thing.

While I can kind of see their point about maintaining two applications for the 
same purpose, and probably a bunch of compatibility routines for the databases, 
I'd be interested to know if any of these "embracing" customers were visually 
impaired. The WWW version is *unusable* via Braille readers. 

I'd also really like to watch anyone in the UI design group for IBMlink 
navigate the IBMlink (or try to do so) apps using a text-only browser. 
I think it would be very enlightening. And darn funny. 

Particularly if we got video of the effort. I'm not sure the audio would be 
family-oriented enough to safely distribute.

Always give hard problems to the laziest man you know. They'll find the
least difficult way to solve the problem. 

Look around for a copy of RXLDEV. RXLDEV is a REXX function package that
allows you to create and manipulate CP LDEVs from REXX. Once you can do
that, you can automate just about anything. 

If all you need is to issue some line-mode commands and trap the output,
don't forget that telnet can be simulated in REXX by using RXSOCKET
calls connecting to port 23. 

Two other must-have tools: SESSION has already been mentioned, and if
you have a privileged ID, you must have a copy of TRACK. I carry them on
a USB drive everywhere I go.

4. Download the SESSION utility from any site having the VM Workshop
tools. You can create arbitrary numbers of sessions (I typically have
8-10 defined) and switch between them with a PF key or by name. Each
session does need to be a separate userid, though; nothing equivalent to
'su' within the same session.

YVETTE's got some more sophisticated features, but SESSION requires zero
installation and configuration; copy the binary someplace convenient,
SESSION FOO PF12, and you're off. Hit PF12 (or whatever you defined the
exit key to be), and you're back to the original session. You can even
run SESSION from inside XEDIT if you need to pop over to another id and
check something out and come right back to where you left off. 

Re: switch user without logoff

[Thomas Kern]

Okay, so how I read your problem is that you have some process running in
another virtual machine and you want to check it without logging off your id
and logging onto the other id. 

There are several ways and I sometimes use all of them. First, spool the
console of the process virtual machine, write status messages to that virtual
console, get the TRACK program to view the current open console buffer. Or get
the VM:Spool product from CA and use it to view the entire console log. Another
way is to write those status messages to a file on a minidisk and use "VMLINK
processid cuu ( FILELIST" to look at the current read-only view of the status
file. An older style of sending status messages is to at regular intervals,
send a punch file with a status message in it to your monitoring userid, and
user RDRLIST/PEEK to view the status messages.

There are more advanced techniques like including an SMSG/IUCV handler into
your process virtual machine to intercept, parse and respond to queries for
status messages.

We have a "session" command which creates an LDEV and presents the VM

referring to, but it's running fine on our z/VM 4.4 system.


Since I connect to VM with some flavour of TN3270E, I usually just open 
another session, that way I can have both VM sessions visible at once.


The "session" command allows me to flip back and forth between two IDs 
with a PF key, but there's nothing like having both visible at the same 
time.


However, I use "session" more and more to log on quickly for a specific 
task because the method we have to use to get logged on is getting more 
and more inconvenient in the name of security. I won't go off on that 
tangent now.. :-)

Re: switch user without logoff

[Rick Troth]

Not sure what you are after, but maybe  #CP DISC HOLD  will help?
To me, it is a lot like the "switch user" feature of some Unix/Linux
X session managers and of Windows (XP) home edition.

If you're connected via VTAM, your "session" usually remains.
If you're connected via TELNET, your "session" usually drops when you
DISConnect or LOGOFF.  But the HOLD option retains the connection.
Very handy.  Conceptually like a "switch user" function.

I second Mike Walter's endorsement of SESSION.

First of all, if i forget: Happy new Year, happy 2007!


Tell the truth i had many problem about posting this problem to list because
SMTP server didnt want to follow in 2006. At least for one week when ive got
a new message what isnt contained: it just a warning message, you dont have
to resend your email. Then i tried again, and that time i was lucky.

So it is just a simple story about the source message, and what i wanted to
say yet: i always very happy i got many help and ideas how can i solve my
problems. So a very big thank you for you all!

Ok, back to the questions. Sorry i start with a little story too for getting
picture a bit more about my line of my questions. Im working at IBM, ive got
this job in end of september, about 3 month after i got my degree.
I knew ill work with mainframes, with VM. Ive got basic and advanced level
knowledges of VM using and administrating. Now me and one of my collegue got
a project what is started to migrating to our country some month ago, almost
the time when i joined. Nowadays i have to check logs and files and -tell
the truth-  ive got many free time. So i started to make some rexx & pipe
prog for my fun (see: questions about using colors) and  i tried to make the
checking  phase a bit more easier if i can (see: problems with  starting
exec's from  an exec).


Nowadays i finished all change what i could do for make things easier, but i
was thinking of maybe possible to do the checking phase (using two user with
method logon by) without have to logon manually to each user. I know it is a
very lazy thing, but while im trying to solve problems i know more the VM
and ill see more its borders, what can i do and what not. And if i can do
it, how.

So this is the answer to your question, what do i want to do ( and a some
kind of why in my long story)

Re: switch user without logoff

[Mike Walter]

One "Sessions" was a freebie "value add" from Amdahl for their customers. 
Great stuff.  Instead of logging on, you issued a DIAL PIE (or whatever 
server name you used) command and it permitted starting up and 
hot-switching up to 12 logons from that single screen.

Didn't Arty Ecock had another program named "session" that built an LDEV 
on an existing logged on CMS userid, and popped you into that session?

The old Amdahl Sessions tool was bought by Technologic Software Concepts 
or Irvine, CA.  They renamed it Pie/VM-Sessions, enhanced and supported it 
for many years before their direction changed. They formally dropped the 
product and its support on January 1, 2000 (killed by Y2K; with few 
customers they did not want to spend time re-writing the code to validate 
the CPU serial number against the 4-digit date).

But PC terminal emulation software has pretty much made it obsolete 
anyway, although with an added cost of a communications connection for 
every emulator session.  With TCPIP, the cost of the connections is pretty 
insignificant - SNA was a little more expensive.

None of those were anything like Linux's sudo.  If the requirements were 
made clearer, perhaps we could address it another way (maybe using SCIF, 
or a server running a command authorization program).

Re: switch user without logoff






There was a package.

It was a user contributed program on VM/SP days.
You would type the program name with a name and it would create a LDEV
device with that session name.

You would then get the VM logo, sign on to that CMS (or do a DIAL to
some multi-user system, such as VSE), and you could hotkey between that
session and the base session.  That is as close to the Linux "su"
command I've ever seen.

Now that it is comming back to me, the package name was "sessions".  In

No, there is no built-in "hot key" function in CP maintain multiple 
terminal sessions on a single (real or logical) connection.  I suggest one 
of the following (in order of preference):

1. Create another emulator session to connect to VM and use your 
emulator's own "jump next" key to switch between sessions.

2. If you are connected to a 3270 terminal controller (e.g. 3174), use the 
Multiple Logical Terminal (MLT) function of the controller to perform the 
switch function.

3. Download the YVETTE package from the VM Download Library.  You can 
program a PF/PA key to act as the "jump next" key.

If

Paging is not too bad on the system (300/sec) and we set the share and

Re: OK Pipers, a new challenge

[Mike Walter]

First guess: Take a peek on VMUTIL's disk to see if you might have an 
ERASE EXEC accessed.
In any case, changing the "CMS" stage to a "COMMAND" stage would prevent 
it from running any accessed ERASE EXECs.

Personally, I'd stop using the stack altogether and re-write the pipe 
(untested) as:

'PIPE (NAME Erase332Stats)' ,
   '| COMMAND LISTFILE * 332STATS A (TODAY NOHEADER', 
   '| SORT 1-8 DESCENDING', 
   '| DROP FIRST 1', 
   '| SPECS /ERASE/ 1 W1-3 NW', 
   '| CONSOLE', 
   '| COMMAND' 
RETURN

OK Pipers, a new challenge






OK, this is a real simple pipe. 

'LISTF * 332STATS A (TODAY STACK' 
'PIPE STACK ', 
   '| SORT 1-8 DESCENDING', 
   '| DROP FIRST 1', 
   '| SPECS /ERASE / 1 W1-3 NW', 
   '| CONSOLE', 
   '| CMS ' 
RETURN 

It erases all "* 332sstats" files except for the lastest one.
I think it works great, but perhaps not.

As you can see, I create a CMS 'erase' command, display it on the
console and execute it.

After all the rexx subsitutions take place and the pipe is build, a
"trace i" shows the following:

   >O>   "PIPE STACK  | SORT 1-8 DESCENDING | DROP FIRST 1 | SPECS
/ERASE / 
1 W1-3 NW | CONSOLE | CMS " 
 
11 *-* RETURN 
 
009 FILES PURGED 
 

I would have expected to see:

erase 090101 332stats a
erase 100101 332stats a
erase 110101 332stats a
etc

so, why am I not getting the CMS command, listed.  Obviously, I'm doing
something wrong here.  But 9 files being purged is the right number. 

The process is being kicked off by VMUTIL.  So I plan on disabling it
and log on and do the commands myself to see what is actually out there.
 But that shouldn't have any effect on why I'm not seeing the CMS
commands echoed to the console.

CP VMDUMP for a mega server

[Jim Vincent]

We are doing a VMDUMP for a 2G linux server and it is taking FOREVER.  If
this was a production server we would be picking daggers out of places I
can't mention here.

Paging is not too bad on the system (300/sec) and we set the share and
reserved for the guest up to maybe help, but nothing seems to get it moving
any.  It is doing about 1000 spool records every 15-20 seconds and we
guestimated it would be about 524288 records; after about an hour it is
less than half done!!

Is this to be expected?  Are we to expect VMDUMP to take that long for
these larger guests or do we have a situation we need to dig into?

Speed is *always* important.  :-)  There are companies who make FICON and 
ESCON "channel extenders" who encapsulate and encrypt channel data on a 
WAN to a remote location.  If you don't have guaranteed WAN bandwidth 
between sites, you may end up with a problem.

Certification of drives attached via a channel extender is typically the 
responsibility of the channel extender vendor, not the drive vendor.  For 
IBM drives, you *may* need an RPQ to obtain IBM support for drives so 
attached.  Check with your business partner or IBM Storage specialist; the 
extender vendor should be able to provide guidance to you as well.

Yes, but only if you're using a QDIO VSWITCH.  VM TCP/IP cannot use a 
layer 2 VSWITCH or Guest LAN.  This also means that if you're using IPv6 
with Linux and with VM TCP/IP, they cannot share a VSWITCH or Guest LAN. 
This isn't a problem with real OSA sharing since the OSA allows both layer 
2 and layer 3 connections on the same OSA - CP doesn't.

People with IPv6 requirements for VM TCP/IP (stack and apps) should let 
their voices be heard ASAP.  [To DB: I already have your vote.]  And if 
you have any drop-dead dates for IPv6 deployment, let us know that, too.

Re: Backup of z/VM and z/VSE

[August Carideo]

I would beg to differ w/ this
you can recover any component of a backed up running VSE system
how many system crashes are planned ? w/ op system down ?
what good is a DR plan if you can only restore from a planned outage ?
VSE utilities should also be used as fallback , such as power off-loads,
fcopy etc.

Daniel,

You can get a valid/usable backup the z/VSE guest dasd with DDR -ONLY IF-
the z/VSE guest is shutdown while performing the backup.

You can use z/OS DFDSS to backup the z/VM and z/VSE dasd but (IMHO) it is
not a wise solution because of the restore considerations. With enough
practice you could make it work. Problem is the z/VSE guest would never
work
correctly unless it were shutdown during the backup.

You can backup the running z/VM system with DDR (minus the page and spool
volumes - format the page and spool volumes, cold start the spool after
recovery). You would have to re-save CMS and other DCSS or use SPXTAPE to
save the information in the spool.

Since you have a z/VM system, this would be a good time to try using z/VM
under z/VM to validate your recovery process. If you forgot something just
scrape the 2nd level system and start over. (kind of like using Changeman
to
maintain Changeman).

Would be glad to discuss with you offline.

The restriction about IPv6 with an IP VSWITCH is only if you were using a

DST Updates for VM on FLEX-ES users

[Mike Hammock]

Daylight Saving Time date change

For VM users who are running on FLEX-ES systems. this may be of interest.

As many of you know, the effective dates for Daylight Saving Time (DST) and
"normal" time changes in 2007 for people in the USA and Canada.  (People in
other countries can stop reading now, this does not affect you.)
If you are running a FLEX-ES system then the underlying UnixWare or Linux
should be updated to reflect these new DST dates.  If you do not update the
DST dates, your system will continue to function properly, but the UnixWare
or Linux displayed dates will be incorrect for several weeks in the spring
and fall, possibly causing some operational confusion.
Cornerstone Systems (with assistance from Fundamental Software) has
packaged the required update files and procedures as a service to our
Cornerstone customers.  As part of our commitment to continuing support for
all FLEX-ES users, we have decided to make this package available to anyone
who wants to use it.  (Normal disclaimers apply, of course.)
If you want to apply this update to your FLEX-ES system, or if you just
want to learn more about the DST date change, you can download the
information, procedures, and needed files from our web site.  Just go to
 http://www.csihome.com/csiforms/zFrame_DayLight2007_Contact.htm
to provide a little tracking information, and that will take you to the
page where you can download a .ISO CDROM image with either UnixWare or
Linux procedures for the update.  Note that the .ISO file is actually
imbedded in or attached to the .PDF file of the instructions, so you only
need to download the appropriate .PDF file and that will include the .ISO
image.

VM users should also update their TIMEZONE_BOUNDARY statements in the
SYSTEM CONFIG to reflect these new dates.
