index not incrementating
Hi, can someone tell me how the index number on the bin logs are incremented? When i update my master machine the changes are still going to $machine-name-bin.001 on my slave its looking for Log_file $machine-name-bin.002 can someone tell me how these number are incremented? the .00# how often, what causes them to increment? also another question is: what happends when the slave machine is rebooted? when it (slave) comes back up does the slave update the database with all the inserts, deletes that happended in the time it took to boot up? I tried rebooting the slave and updating the master and when the slave came back up it was just in a state of waiting for new changes...it did not populate the missing data. Did i do something wrong? I am fairly new to replication and researching weather it is a feasible and safe transition to go to for our production machines. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

stability of replication?
I just wanted to know how stable is mysql databse replication is? What we have in mind is a tiered system. $master (california)-(internet ssh tunnel) \$slave (texas) 10 other slave machines on the same network (running 5 separate db per machine) \$slave (san fransisco) 10 other slave machines on the same network (running 5 separate db per machine) \$slave (new york) 10 other slave machines on the same network (running 5 separate db per machine) How fesible would this be? and has anyone worked with replication on a large scale? We're dealing with 2500 tables about 65k total records Read/Write to the master will be like 50 per second Any input or links to documentation is much appreciated. - Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail [EMAIL PROTECTED] To unsubscribe, e-mail [EMAIL PROTECTED] Trouble unsubscribing?

If i put a server-id in the slave my.cnf file and start up the database with safe-mysqld, it starts and dies with this error in the log file. unrecognized option `--server-id=2' -Original Message- From: Gerald Clark [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 05, 2001 7:25 AM To: Duc Chau Cc: [EMAIL PROTECTED] Subject: Re: replication problem The slave does not have a server-id.

FW: mysql db replication security across the internet
Can anyone tell me or point me to documentation on how to securely do database replication over the internet? I need to replicate to machines in datacenters in diffrent states. How feasible is this? Has anyone done it? What are the security concerns with doing this via the net?
