Replicating with all servers in a cluster
An additional benefit of creating a cluster is that it can simplify your replication topology and increase the reliability and performance of replication. This is because you can set up a server outside the cluster to replicate with all the servers inside the cluster. You do this by creating a single Connection document that specifies the server outside the cluster as the source of replication and the cluster name as the destination of replication. Then, every database on the source server that has a replica in the cluster replicates. If the cluster contains more than one replica of a database, the source server replicates with only one of those replicas, and cluster replication propagates the changes to the other replicas in the cluster.
Replication with a cluster is more reliable than replication with an individual server because Domino replicates with any server in the cluster that contains a replica of the database it is processing. Therefore, if a server in the cluster is unavailable, replication can still proceed if another replica exists in the cluster. Replication with a cluster can also improve performance because Domino uses workload balancing when choosing a server with which to replicate.
Note When replicating with a cluster name, select Pull Push, Pull Only, or Push Only as the replication type in the Connection document. Pull Pull replication does not work with a cluster name.
The server that initiates replication must be running Domino Release 4.5 or higher. It does not have to be running Lotus Domino 6.
Note Before replicating with a cluster name for the first time, the source server must access one of the clustered servers directly once. When this occurs, Domino populates the source server's cluster cache with the names of the servers in the cluster. This makes the source server aware of the servers in the cluster.
