Re: Time synchronization

What is the most sensible way to synchronize the time in a mid-size

- 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 ?


A GREAT DEAL depends on your requirements!

Do you want all you systems to keep UTC, correct within a millisecond or two? Or are you happy if they all have the SAME time even if the time is in error by several minutes?

I use NTP on both my VMS and my Solaris systems. It seems to work well enough. On VMS it WILL bury you in log files that usually tell you nothing worth the disk space they occupy. You will probably want/need to have a weekly or monthly cleanup job.
