Replace DTSS clock by NTP
We want to remove the clocks and use NTP to get the time.
What do I need to do to continue using DTSS but get the correct time using NTP ?

Re: Replace DTSS clock by NTP
one of our customers uses DTSS$NTP_PROVIDER on some of their DTSS servers and then distributes the time using DTSS.

Re: Replace DTSS clock by NTP
Did they need to modify it ? Bugs/pitfalls ?

Re: Replace DTSS clock by NTP
AFAIK, they used the version from
http://antinode.org/dec/sw/dtss_ntp.html
Try it on a test system first...

Re: Replace DTSS clock by NTP
we are using dtss$provider_ntp.exe since at least two years. The machines running this image get the time from ntp and distribute this time via DTSS to our OpenVMS Environment. We never had problems with it until now.

Re: Replace DTSS clock by NTP
try SYS$COMMON:[SYSHLP.EXAMPLES.DTSS]DTSS$PROVIDER.H
Did you install/configure DECnet-Plus to include DTSS server ?

Re: Replace DTSS clock by NTP
as far as I remember, the DTSS$PROVIDER_NTP examples had been delivered with 'some' DECnet-OSI patch in the past - so it might depend on your patch history, whether you have this file(s) or not.

Re: Replace DTSS clock by NTP
Unless you're specifically using DECdts (DTSS) clerks and servers for the distribution of time values, I'd suggest disabling it and switching to NTP -- other than the distribution of the time values, what DECdts once provided is now part of base OpenVMS, with V7.3 and later. The DECdts APIs and the DST switch-over stuff (qv: AUTO_DLIGHT_SAV), for instance, are now all in base OpenVMS V7.3 and later.

Re: Replace DTSS clock by NTP
There's also a copy on my server, next to all
the other files, but I failed to provide a
link to it.

I keep meaning to do that someday...

Re: Replace DTSS clock by NTP
We have a test-, an integration- and a production environment. On the integration- and production systems we are still using DTSS for synchronizing the time.
The test systems have to participate the year end test. Involved in this year end tests are also linux, sun solaris, hp ux and nt systems. The year end test starts in October and ends in mid December. During this time, we test the behaviour of our applications and we simulate the time starting in October and ending end of February. Thats why we have to adjust the time on those test systems several times, what means we are doing jumps sometimes one day, sometimes one week to the future. It was easier to use a test NTP server too for those systems, because every system understands NTP and we should not have time differences of more than 5-10 s on the whole test environment. Our experience with NTP is very good.
Now we have already moved, or will still move all of our systems into a secured zone, which is only accessible over firewalls. This means we have to change the IP addresses of all those machines we move. Because we have anyway to touch each system, we decided to move to NTP time synchronization on all of our systems.
The short meaning of this long story: We trust in NTP, because of the good experience with NTP.

Geni
