Improving server availability in a cluster
Clusters are designed to improve server availability.
To configure a Domino® server
for clustering, specify a default port in the server's NOTES.INI file
by using the following setting:
Server_Cluster_Default_Port=portname
. When you specify a port, you limit cluster replication to that
specific port even if the port has failed. If the setting Server_Cluster_Default_Port=
is not defined, the standard server search algorithm is used and all
ports are tried. If the designated port fails, that is, the port specified
in the Server_Cluster_Default_Port=
setting, the
server may be accessible from another port.
You can allow the use of other ports by entering this setting in
the server's NOTES.INI file:
Server_Cluster_Auxiliary_Ports=portname
Note: If you do not specify a default port in the setting
Server_Cluster_Default_Port=
,
all ports are tried. The Server_Cluster_Auxiliary_Ports=
setting can
be set to any one of these values:
- Blank -- Do not specify an auxiliary port. The user sees no change in the existing behavior.
- * (asterisk) -- Specify * in the
Server_Cluster_Auxiliary_Ports=
setting. All ports are checked if the server specified in the settingServer_Cluster_Auxiliary_Ports=
cannot be reached. - List of port names separated by a comma -- Specify a comma delimited
list of port names in the
Server_Cluster_Auxiliary_Ports=
setting. The ports in the list are checked for the desired server.
