Hi All As per previous Q "mentioned below" I did try using t_replicate however once the client A logons on to server A it just keeps sending subscribe requests to server B Hi All I have the following scenario Openser Server A --> Uses Localhost MySQL Server Openser Server B --> Uses ServerA MySQL server Each server is in a different location. Both servers share the same database. I.e. in other words a user can successfully logon to either server. Both servers have a similar configuration file. My problem at hand is the following User A and User C logon to Server A User B logs on to Server B User A and User C can call each other. How can User A and C communicate with user B ? Can anyone provide me with a working example.
