Re: MySQL database synchronizing from 2 locations
Richard- If you have 2 or more servers which you want to dedicate to MySQL you may want to look into MySQL Clustering To focus on sync'ing I would read about the the 'syncronisation replication' vs 'asynchronous replication' that the Participating Nodes employ http://www.mysql.com/news-and-events/newsletter/2003-02/a000125.html HTH/ Martin-- This email message and any files transmitted with it contain confidential information intended only for the person(s) to whom this email message is addressed.

RE: MySQL database synchronizing from 2 locations
Hi, Set up two-way replication between Corporate and Manufacturing. As long as a live network connection is available between the two sites, replication will carry on. Make sure that all your hardware is able to handle the peak I/O loads, in order to keep replication humming along seamlessly. If the connectivity between the two servers is lost, replication will gracefully auto-recover. You will need to set up some heartbeat script to monitor the connectivity, and SMS/email you if it is lost, allowing you to check on it.

RE: MySQL database synchronizing from 2 locations
Replication works with Windows (we do it extensively here at work). And it's definitely one option. But if there are any problems, then without some monitoring mechanism, you'll not be alerted if replication chokes (all that will happen is that updates to the slave will seemingly just stop). You can implement any of a bunch of alerting and self-repair mechanisms. Other methods of transferring the data are similarly challenging. You can do an automated MySQLDUMP on a periodic basis with with a --master-data option (in case you do perform the replication) just to "be sure" OR just do MySQLDumps each night (depending on the volume). It all depends on the degree and need for whatever level of synchronicity.
