4.3. Failover in a cluster
A cluster's ability to redirect requests from one server to another is called failover.
When a user tries to access a database on a server that is unavailable or in heavy
use, Domino directs the user to a replica of the database on another server in the
cluster.
The Cluster Manager on each cluster server sends out probes to each of the other
cluster servers to determine the availability of each server. The Cluster Manager also
checks continually to see which replicas are available on each server. When a user
tries to access a database that is not available, the user request is redirected to a
replica of the database on a different server in the cluster. Although the user
connects to a replica on a different server, failover is essentially transparent to the
user.
Example
This example describes the process that Domino uses when it fails over. This cluster
contains three servers. Server 1 is currently unavailable. The Cluster Managers on
Server 2 and Server 3 are aware that Server 1 is unavailable.
1 A Notes user attempts to open a database on Server 1.
2 Notes realizes that Server 1 is not responding.
