CLUSTERS

Managing replication in a cluster
You should use both cluster replication and standard replication in a cluster and run them both at the same time. Cluster replication is the primary means of replication in a cluster, while standard replication updates any databases that the Cluster Replicator couldn't update.

You should schedule replication in a cluster on a regular basis to be sure that databases are properly updated even when they aren't replicated by the Cluster Replicator.

As you move or copy databases into a cluster, be sure to check the access control list and other restrictions that are copied with the database. All servers must be able to replicate all replicas of a database for a cluster to work properly. In addition, users' access rights should be the same in every replica of a database so that they see the same thing and can perform the same tasks if they fail over. Make sure that any access restrictions to a database in a cluster are uniform across all replicas. Also, be sure that the setting for replicating unread marks is the same across all replicas.
