Clusters are designed to improve server availability. To configure a IBM® Lotus® Domino™ server for clustering, specify a default port in the server's NOTES.INI file by using this 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= NOTES.INI setting, the server may be accessible from another port. You can allow the use of other ports by entering this NOTES.INI setting in the server's NOTES.INI file: Server_Cluster_Auxilary_Port=portname. Specify * in the Server_Cluster_Auxiliary_Ports= setting.
Note If you do not specify a default port in the setting Server_Cluster_Default_Port=, all ports are tried.
Valid values are:
Blank = Do not specify an auxiliary port. The user sees no change in the existing behavior.
* (asterisk) = All ports are checked if the server specified in the setting Server_Cluster_Default_Port= 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.
