2. Clock issues in VM

I don't know if this is valid in VM/SP 5 (too lazy to check), but I found this:

*
"Time of Day Clock Considerations"

"By default, the guest will see the real Time-of-Day (TOD) clock
value of the real machine. Specify OPTION TODENABLE in the dir-
ectory entry for guests that need to use the SCK instruction to
set the virtual machine's TOD clock. OPTION TODENABLE is not
necessary to specify a time zone offset in a guest virtual
machine. "

All the above relates to a VM that's using SIE to run its guest
virtual machines. SIE can allow VM to manage a private virtual TOD
clock for each guest, with any baggage you want.

In VM/370 at any level before XA there is just no way to intercept a STCK.

Maybe you just need to spool your punch "CONT" before punching your jobstream, and then "CLOSE" it afterwards?

e.g.:

spool punch cont to JS24
punch asm1 assemble
punch asm2 assemble
punch asm3 assemble
spool punch nocont
close punch

If that's how you already are doing it, then maybe you need to spool your MVT reader "CONT"?

SPOOL 00C 2540 READER * CONT

Maybe that will cause VM to present MVT with "intrq" instead of "eof"?

So maybe you just need to add the "TODENABLE" option to your directory entry?

Like I said, it's been a *LONG* time since I've messed with such things!

I don't know

2. Clock issues in VM

When I start MVT natively in Hercules with "YROFFSET -28" in the configuration, the clock is set to today's date in 1995 and passed to MVT during IPL. However, when I start MVT under VM, I get an IEE116A message, saying the TOD clock is invalid. I used the YROFFSET -28 command to reset the date back to 1995 in VM and that works for VM, but I still have clock problems with MVT. Is there is a technique I can use in VM to set the date back for a single virtual machine, without affecting VM/SP itself? If I can do that, I could run VM/SP with accurate dates and still be able to work on the date issue in MVT.

Since STCK is an unprivileged instruction, there is nothing VM/370 can
do to intercept it. But other than the convenience of having different
TOD values for different guests, I don't think lack of that facility
is your root problem. MVT used an epoch date of Midnight Jan 1st, 1960
(time zone unspecified, but typically local). So your clock value
needs to be 60 years later than the base you want (1995 or whatever to
get the weekdays lined up). Back in the day there was certainly at
least one mod to change MVT's epoch date to match that of MVS, and I
expect that one is floating around in the Hercules OS/360 community
somewhere.

I am running Kevin Leonard's Turnkey MVT under VM/SP 5 and I've run into a couple issues I'm hoping someone here may be able to help me with.

1. VM sends EOF to the reader on input

When I am running MVT by itself, with no HASP or ASP running, I can start a reader and read job streams punched to the VM from other VM users.? However, after every job stream is read, VM returns an EOF and the reader task is closed and has to be restarted.? This is what I would expect if it was reading from a real 2540 and the operator had pressed the EOF button along with START.? Hercules has the "intrq" configuration option for the reader that causes it to return an intervention required as opposed to end of file after the last card is read (i.e. no EOF button press).? Is there anything in VM to do something similar?? I haven't found anything in the manuals or help text yet, but if there is, this would allow me to submit multiple jobs without having to restart the reader task every time.

Yes, I extrapolated from the installation procedure for dirmaint to get that far.

And, as luck would have it, I was able to get it all done today. It turns out that the release of OSA/SF for VM/ESA is the same as that for z/VM v4, and the same installation documentation applies, and I was able to find that.

As was the case with dirmaint, the ADCD distribution's OSA/SF has had some of the installation steps performed already. Specifically, the copying in of the example files had already been done.

But first it's necessary to enable the product:

LINK MAINT 51D 51D M
ACCESS 51D D
VMFINS ENABLE PPF 2VMVMV20 OSA

This creates 2VMVMV20 PRODSYS A. Place the contents of this file (one line) in the appropriate place in the SYSTEM CONFIG file on CF1 using the normal process for accessing CP-owned minidisks.

Then, log on as 2VMVMV20 and pick up from section 6.6 in the Program Directory for OSA/SF for zVM V4 manual, to perform these steps:

access 100 e
access 200 f
vmfcopy * * e = = f (prodid 2VMVMV20%OSA olddate replace

access 300 e
access 400 f
vmfcopy * * e = = f (prodid 2VMVMV20%OSA olddate replace

access 7f00 e
access 8f00 f
vmfcopy * * e = = f (prodid 2VMVMV20%OSA olddate replace

access 2c2 e
access 200 f
vmfcopy * sampprof e = = f (prodid 2VMVMV20%OSA olddate replace

Then log off from 2VMVMV20. It should now be possible to log on as OSADMIN1, and execute IOACMD commands.

For safety's sake, I first tested all of this under Hercules, before going over to LSSM and doing it on the S/390. There, I was able to use IOACMD GET_OAT to successfully pull out the OAT data from a functional OSA-2 board this this evening. Later this week I will attempt to reinitialize and configure the second OSA-2 board.

Thanks to everyone here who pointed me in the right direction!

Hi Dave,

Hi Jim, I'm trying to enable OSA/SF. It's in the directory, and its minidisks are present.

My concern is that the process for getting it running may be specific to the ADCD distribution. I say this because this was the case with dirmaint; several of the steps in the installation procedure had already been done for dirmaint in the ADCD.

Thanks,

Hey folks. I want to enable/configure/etc a software package that shipped as part of the VM/ESA 2.4 ADCD distribution. I've not been able to find any references on how to do this. Is it just a matter of enabling it in SYSTEM CONFIG? Is it done with vmses/e? I'm stuck. Can anyone point me in the right direction?

What guest OSs still support LCS?

As far as VM operating systems go, I can confirm that VM/ESA 2.4.0 supports LCS, as do all modern z/VMs. Modern z/VM supports OSA as well (in either mode too: Layer 2 mode -or- Layer 3). I have no idea what type of networking support VM/SP5 or earlier had, if any.

As far as z/OS is concerned, all modern z/OS support all three types: CTCI, LCS or OSA (but its OSA support is only Layer 3 though).

Can't speak for any other guest O/Ss.

I ask just because the z/OS V2.5 announcement letter
()
back in 2021 said this:

"Withdrawal of support for VTAM? Link Station Architecture (LSA) and
TCP/IP LAN Channel Station (LCS) devices

As stated in Hardware Announcement 121-029, dated May 4, 2021, many
IBM Z clients continue to rely on Systems Network Architecture (SNA)
applications for mission-critical workloads, and IBM has no plans to
discontinue support of the SNA protocol, including the SNA APIs.
However, IBM Z support for the SNA protocol being transported natively
out of the server using OSA Express 1000BASE-T adapters configured as
channel type “OSE” will be eliminated in a future hardware system
family. With the support for OSE planned to be discontinued, support
for the related VTAM and TCP/IP device drivers is also planned to be
discontinued. IBM intends z/OS V2.5 to be the last z/OS release to
provide support for LSA (SNA) and LCS (TCP/IP) devices. z/OS systems
that have workloads that rely on the SNA protocol and utilize OSE
networking channels as the transport should be updated to make use of
some form of SNA over IP technology, where possible, such as
Enterprise Extender.

Removal of OSA DEVICE/LINK/HOME configuration support

z/OS V2.5 is planned to be the last z/OS release to provide support
for the TCP/IP profile statements DEVICE, LINK, and HOME for OSA
connectivity. All z/OS users who currently use DEVICE, LINK, or HOME
for OSA connectivity should migrate to the INTERFACE statement for
defining OSA Express connectivity in their TCP/IP profile. "

Wasn't clear to me if z/OS leads or lags other modern OSs in dropping
support for LCS.
