Re: Time synchronization
Marc,
Because of the "if it ain't broken, don't fix it" theorem, we run DTSS
on all nodes. In each datacenter, two of the nodes are configured as
server, the rest is clerk. Also, in each datacenter, one server also
runs the DTSS$PROVIDER_NTP as found in SYS$COMMON:
[SYSHLP.EXAMPLES.DTSS].
The only problem is that there is no automatic detection of ntp
servers (although I do not know if there is such functionality in ntp
at all). When the the network team saw it fit to replace the ntp
servers they did not bother to tell us.
Regards,
Bart Zorn

What is the most sensible way to synchronize the time in a mid-size
OpenVMS farm today ?
- Use NTP everywhere and forget the rest ?
- Use DTSS with an NTP time provider ?
- Synchronize time on internet time server ?
- Use a radio time source ?
- ...
The installation I speak about is made of about 20 systems, some
clustered, some not. Mix Alpha/Itanium. And surrounded by a much
larger population of Unix and Windows systems.
What are other people over here doing ?
