Hi, I just start to use the Openser as the presence server. I tested with the eyebeam. The server saved the presentity information to the MySQL server. It worked well. I have questions. I would like to setup two presence servers. One is active, and the other is stand-bye. If the active is down, the client sends a message to the stand-bye. How does the presence server know that it is active or stand-bye? How do I set it up? How do I replicate the database between servers? If the active is down, how do I make it up running again?
Thanks.

You have to decide if it is hot-standby or cold standby. Mostly cold-standby is used. That means only one SIP proxy is running. The SIP proxy is using a virtual IP address. If the proxy fails (or the hardware fails) the standby server will detect this, will configure the virtual interface and start the SIP proxy. Take a look at "heartbeat" and "ultramonkey".
If you are using hat standby, you configure the "fallback2db" option and either - use a single database - use 2 databases with master-master replication - use a mysql cluster
