Not quite true. If you have a small number of synced gateways talking to a Trust Server (which is actually the standard gateway software running in a Trust Server mode), when a station moves repeaters, the update is virtually instantaneous across all repeaters.
In fact, after the initial database push, all you ever see are updates. However, if there are repeaters that are out-of-sync (determined by the UTC time-stamp on the database updates), then the Trust Server appears to fall-back to a periodic update, and that period is set by the time it takes to get round each repeater with the database update. So the issue is that the database update mechanism is not robust enough to cope with the fact that some repeaters may be uncontactable. This creates the current issues - 4 months ago, the interval between database updates was about 51 minutes. Today, I've counted at 1 hour. And it's the full database every time. 73 David - G4ULF --- In [email protected], "Woodrick, Ed" <ewoodr...@...> wrote: > > AFAIK, the ONLY updating that occurs is to the Trust Server and then > replicated out.
