replication
Hi, I would like to know how mySQL manage the identity (auto increment counter) in a replication environment when 2 servers are both master on the same database. Here's a sample of my problem. We have 2 servers running mySQL. Server1 replicate data on server2 and server2 replicate data on server1 for the same table on the same database. Both server are connected together. At this point, there's no problem, the two server shares the same identity and the key grows up with new record. But, now, suppose that the connection between server1 and server2 is broken (Two different site for example and the link between site goes down) during one hour or one day. On each server, people insert records because both of them continious to see the server assigned to their site. When the link go up again, and the server will begin to replicate data.How the identity created will be reassigned or affected ? Does both mySQL server had assigned the same key ? Is there some solution to manage this problem ? What are you thinking of this problem ? What are you thinking of Britney Spears ? ;o) This solution is going to be implemented in high critical environmment, with 100 percent uptime needed, that's why we want to be sure we use the better solution.

RE: replication and auto_increment
hi, here is the problem ... think about this : serverR1 / serverR2 : replication servers serverWWW : webserver serverWWW reads/writes data from/to serverR1 serverR2 replicate serverR1 data serverR1 crashes serverWWW reads/writes data from/to serverR2 serverR1 (up) replicate serverR2 data the goal of this architecture is to prevent to lose data i don't know if it's possible with mysql (that depends of internal auto_increment id management) -Message d'origine- De : gerald_clark [mailto:[EMAIL PROTECTED]] Envoye : jeudi 19 decembre 2002 16:59 A : [EMAIL PROTECTED] Objet : Re: replication and auto_increment Do not allow inserts on both machines.
