I have a task to replicate data changes from one server (A) to another server (B) and then in the event of server A failing to use B as the main server and replicate back to A when its live again. I would need the replication to be in real time . . .
whats the best method for this and how do i go about setting it up?
I've been reading through transactional and merge technologies, could someone please guide me to the best and most practical solution and guide me through the settings.
Greatly appreciated folks
