  • Hi

    I am kindly asking that you please send me a step by step tutorial on how to set up fan in replication with two separate databases on two master servers being replicated onto one shared database on a slave machine using tungsten replicator. It is my first time to use tungsten so I need a detailed approach right from installation to configuration and lastly testing in linux ubuntu. Currently I am using mysql.

    I have searched the internet and all I can find is the fact that it is possible but not how exactly to do so.

    Your assistance will be greatly appreciated.
