Introduction | Information Center
The Cluster Options page allows you to enable and configure a clustered server environment and specify which node in the cluster is the lead host. You can edit the Cluster Options page from any node in the cluster because each node accesses the same IBM Alphablox Repository. You can configure the following options on the Cluster Options page:
Check this box to enable clustering. If you check this box, the Lead Host IP Address field must also be configured.
Enter the hostname or the IP address of the computer in which the lead host node on which IBM Alphablox cluster is running. For example, if the lead host computer name is SPIDER, enter SPIDER in the text box.
Enter the name of the port in which the lead host listens on for cluster broadcast messages. The normal node host(s) broadcast messages on this port to communicate with the lead host. The port must not be in use by any other process or the cluster manager will fail to start.
Enter a number for the maximum amount of hosts in your cluster. When the limit is reached, no other hosts are permitted to connect to the cluster.
Specifies the maximum amount of time (in seconds) each normal node host will use to attempt to connect to the lead host. If the connection is not completed in the specified time, the normal node host does not join the cluster.
After making any changes, click the Save button to save your changes to the IBM Alphablox Repository. You must shut down and restart each node in the IBM Alphablox cluster to enable clustering or to enable any of the changes made to the Cluster Options page.
