3 Instead of displaying a message that says the server is not responding; Notes
looks in its cluster cache to see if this server is a member of a cluster and to
find the names of the other servers in the cluster. (When a Notes client first
accesses a server in a cluster, the names of all the servers in the cluster are
added to the cluster cache on the client. This cache is updated every 15
minutes.)
4 Notes accesses the Cluster Manager on the next server listed in the cluster
cache.
5 The Cluster Manager looks in the Cluster Database Directory to find which
servers in the cluster contain a replica of the desired database.
6 The Cluster Manager looks in its server cluster cache to find the availability of
each server that contains a replica. (The server cluster cache contains
information about all the servers in the cluster. Cluster servers obtain this
information when they send probes to the other cluster servers.)
7 The Cluster Manager creates a list of the servers in the cluster that contain a
replica of the database, sorts the list in order of availability, and sends the list
to Notes.
8 Notes opens the replica on the first server in the list (the most available
server). If that server is no longer available, Notes opens the replica on the
next server in the list. In this example, Server 2 was the most available server.
When the Notes client shuts down, it stores the contents of the cluster cache in the
file CLUSTER.NCF. Each time the client starts, it populates the cluster cache from the
information in CLUSTER.NCF.
5. Lotus Domino cluster configuration
When configuring the Lotus Domino cluster, it should be determined if a private LAN
for cluster is needed or not. Following points should be considered for the same.
To make a busy cluster more efficient, private network for the cluster can be created.
To do so, install an additional network interface card in each cluster server and
connect these network interface cards through a private hub or switch. The main
reason for creating a private LAN for your cluster is to separate the network traffic a
cluster creates when it uses cluster replication and server probes. A private LAN can
leave more bandwidth available on primary LAN. If a lot of cluster replication
activity is anticipated, a private LAN should be created.
6. Data Protector Configuration
Each Domino server will have the Data Protector Lotus Notes integration agent and
the Data Protector disk agent installed. The location of the Data Protector Cell
