Cluster and Replication

I have two servers, A & B, at a remote site that are clustered. I have a third server, C, at an operations center. C replicates with A every 15 minutes. My question is, if A goes down and B, as the clustered partner, takes over, does C begin replicating with B? Or is there a need to manually intervene? Thanks…

If A,B & C are part the same cluster, A is already cluster replicating with C. However cluster replication can “miss” data due to queue contention. If A and C are not on the same notes network a replication document should be configured to allow replication between A & C.

Since you are WAN clustering I would recommend you look at a few Domino stats to confirm cluster replication is happening in a timely manner.

Replica.Cluster.WorkQueueDepth, Replica.Cluster.WorkQueueDepth.Avg Average

Replica.Cluster.WorkQueueDepth.Max

Replica.Cluster.secondsonqueue.avg

replica.cluster.secondsonqueue.max

the last value defines the “lag” between the primary server and the corporate server

Thanks everyone, I appreciate the quick responses…

only A & B are clustered, C is not part of the cluster so in order for C to replicate with B if A goes down, a connection between B & C will need to be enabled.

scheduled replication will not fail over.
