Re: MySQL Master Master Replication and data loss
Dear Suresh, Thank you. In MySQL Replication, as the slave itself takes the writes from master but in how much time period does slave goes to master. is there any parameter where I can set this. that after every 60 seconds slave should write data from master to its own local database. -- Regards, Manasi Save Quoting Suresh Kuna sureshkumar...@gmail.com: Hi Manasi, As both are implemented by replication, there is a possibility for loosing data.

Re: MySQL Master Master Replication and data loss
Hi Manasi, Inside MySQL, there are no such parameters and the Slave delay depends on different things like network between Master and Slave, load of the MySQLD server etc... To make the slave behind for a particular period of time, use mk-slave-delay tool from the the maakit. It help your slave to be lack for a particular period of time.

MySQL MASTER/MASTER REPLICATION
In my RHEL5, I am using this link to create MySQL replication an did work the first time I did it: http://crazytoon.com/2008/02/29/mysql-how-do-you-set-up-mastermaster-replication-in-mysql-centos-rhel-fedora/ I change the ip address and the hostname and it is not working now.

Re: MySQL MASTER/MASTER REPLICATION
is your mysql running on the master host i,e 10.100.1.170 Also can you please execute show status on that host to see how long the server is up, may be the server is restarted and your slave is retrying on the same old connection HTH, -srini Néstor wrote: In my RHEL5, I am using this link to create MySQL replication an did work the first time I did it: http://crazytoon.com/2008/02/29/mysql-how-do-you-set-up-mastermaster-replication-in-mysql-centos-rhel-fedora/ I change the ip address and the hostname and it is not working now.

Re: MySQL MASTER/MASTER REPLICATION
YEs, both of MySQL are running on each system. Show status display a big long list of items, any specific? uptime is 3239 on 10.100.1.170 uptime is 3353 on 10.100.1.171 Thanks, Néstor :-) On Tue, Apr 1, 2008 at 3:46 PM, Srini [EMAIL PROTECTED] wrote: is your mysql running on the master host i,e 10.100.1.170 Also can you please execute show status on that host to see how long the server is up, may be the server is restarted and your slave is retrying on the same old connection HTH, -srini Néstor wrote: In my RHEL5, I am using this link to create MySQL replication an did work the first time I did it: http://crazytoon.com/2008/02/29/mysql-how-do-you-set-up-mastermaster-replication-in-mysql-centos-rhel-fedora/ I change the ip address and the hostname and it is not working now.
