each server in a cluster considers its own database to be the cluster database
host. Because each cluster should have only one database host, you must update
the cluster configuration accordingly.
example, if you have two server groups (Servergroup A and Servergroup B), each
containing a Publisher and a Subscriber, you would do the following to update
the cluster database host details:
cluster database host password for Servergroup A using Servergroup A's own host
cluster database host password for Servergroup B by entering the IP address and
cluster database password for Servergroup A.
Repeat Step 2
for other server groups in the cluster.
If you use
hostnames, then the hostname must be resolvable using DNS. If DNS is not
configured or DNS is unavailable for any reason, hostname resolution fails and
cluster functionality is impaired. It is recommended that the DNS configuration
include redundant entries to prevent unavailability. Alternatively, the IP
address of the cluster database host can be configured on this screen. The
hostname can begin with a numeric value.
