I agree with in the first 4 points ¿Why you cannot sync more than one client at the same time?
Yes, it's very complex Pepe Llopis -----Mensaje original----- De: profox-boun...@leafe.com [mailto:profox-boun...@leafe.com] En nombre de Paul McNett Enviado el: martes, 08 de mayo de 2012 20:26 Para: profox@leafe.com Asunto: Re: DBF Synchronization On 5/7/12 2:39 PM, MB Software Solutions, LLC wrote: > Good points, but begs the question: is this a 1-way synch or 2-way?

I have five things to offer as requirements for true 2-way synchronization between any number of clients: 1) all timestamps stored in UTC (duh). 2) all clients sync with ntp server regularly to avoid time drift 3) UUID primary keys generated on the client side 4) transaction log kept on server and on client for use in the 2-way sync 5) syncing a client to a server should block other clients from syncing at the same time Paul [excessive quoting removed by server] _______________________________________________ Post Messages to: ProFox@leafe.com Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/2940CAD843CD42E9ADE3ED7F1F6B040C@LENOVO1 ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
