Dennis,
You should be able to find the text in the <prodid> MEMO file (for example,
5VMCPR40 MEMO). If you ordered electronically, the MEMO should be located
in the SHIPDOCS file.
In case others have the same question, here's the contents of the memo as
they relate to VM64814:
Memo to Users for APAR VM64814
The following configuration file operands have been added by this APAR:
FEATURES ENABLE STP_Timestamping
tells CP to enable the STP protocol (if the STP facility is
installed) and apply timestamps to all XRC-capable DASD devices.
FEATURES ENABLE STP_TIMEZone
FEATURES ENABLE STP_TZ
tells CP to enable the STP protocol (if the STP facility is
installed) and obtain timezone information automatically from the STP
server.
FEATURES ENABLE XRC_OPTional
when STP_Timestamping is also enabled, this will allow non-
timestamped I/O to be issued whenever STP is in an unsynchronized
state, as opposed to deferring I/O until STP synchronization com-
pletes.
FEATURES ENABLE XRC_TEST
tells CP to timestamp I/O regardless of STP availability. This
option is meant only for vendor and testing purposes, and can only be
specified for systems running within a virtual machine.
The following commands have been added by this APAR:
QUERY STP
returns information regarding the current state of STP usage on the
system.
The following commands have been modified by this APAR:
DEFINE TIMEZONE
this command cannot be issued while STP_TIMEZone is in effect.
SET TIMEZONE
this command cannot be issued while STP_TIMEZone is in effect.
QUERY TIMEZONE
this command was updated to include STP timezone boundary information
when STP_TIMEZone is in effect.
The following messages have been added:
HCP985E
HCP986I
HCP987E
HCP988I
The following publications have been modified:
CP Messages and Codes (GC24-6119-07 and GC24-6177-01)
New entries were added for the messages referenced above.
CP Planning and Administration (SC24-6083-07 and SC24-6178-01)
New entries were added for the FEATURES statements described above.
CP Commands and Utilities Reference (SC24-6081-07 and SC24-6175-01)
A new entry was added for QUERY STP.
Entries for SET TIMEZONE, DEFINE TIMEZONE and QUERY TIMEZONE were
updated.
System Operation (SC24-6121-03 and SC24-6233-01)
Added the following paragraph to Chapter 3 'Bringing up the System'
under the heading 'Setting the Time of Day Clock':
If your hardware is enabled and configured for Server Time Protocol
(STP) and
this feature has been enabled in your configuration file (using the
STP_TIMESTAMPING or STP_TZ features statements), you will not receive
any
prompts to change the TOD clock. Instead, STP is automatically used to
initialize the TOD clock with the STP-coordinated TOD value. When the
TOD
clock is initialized, you will receive message HCP986I "TOD Clock
Synchronized via STP."
Hope this helps,
Matt

Matt,
I'm running z/VM 5.4.0, so the applicable PTF is UM33146. I looked in
UM33146 $PTFPART, but I didn't find a UMEMO section. Is there somewhere
else that I should be looking for the memo? I'll order the 6.1.0 PTF and
see if it's there.

Hi Dennis,
There is a memo-to-users file included with VM64814 that describes the new
FEATUREs statements that are included as part of XRC timestamping support.
I believe that these statements are the additional step that you are
referring to.
You can certainly pick up VM64814 today and use XRC timestamping. VM64816
will bring along a few internal changes, but nothing that would prevent
you from using XRC timestamping today.
Thanks,
Matt

I understand that VM64814 adds XRC timestamp support. The PTF's are
available. The z/VM platform update at SHARE mentioned that there would be
a SYSTEM CONFIG change to activate it. Where do I find information on
that? The recent SSL changes had a nice web page with all the details, and
one of the PTF's described the changes. I haven't been able to find any of
that for VM64814. The APAR and PTF just say "new function". If it weren't
for SHARE, and someone who told me what the APAR was for, I'd have no idea
what new function I was putting in, or that an additional step was required
to activate it.
I found a couple of references on the IBM site that said VM64814 and
VM64816 would add the function. VM64816 is "assigned to a programmer".
Does VM64814 do anything without VM64816? Will VM64816 provide the
documentation?
