A Lotus® Domino® cluster is a group of two to six Lotus Domino servers that provides users with constant access to data, balances the workload between servers, improves server performance, and maintains performance when the size of your enterprise increases. The servers in a cluster contain replicas of databases that you want to be readily available to users at all times. If a user tries to access a database on a cluster server that is unavailable, Domino opens a replica of that database on a different cluster server, if a replica is available. Domino continuously synchronizes databases so that whichever replica a user opens, the information is always identical.
To create a cluster, you must have at least Author access, Delete Documents rights, and the ServerModifier and ServerCreator roles in the Lotus Domino Directory, and at least Author access to the Administration Requests database.
If possible, use the Lotus Domino administration server when creating a cluster. The administration server does not have to be part of the cluster.
See Domino Administration Help for detailed information on creating Lotus Domino clusters and managing cluster replication.
If a server already belongs to a different cluster, you do not have to remove the server from that cluster before you add it to the new cluster. The Lotus Domino Cluster Administration Process removes the server from the original cluster and then adds it to the new cluster.
To create a cluster of IBM® Lotus Quickr™ servers, perform the following steps:
- From the Domino Administrator, click File -> Open Server to open the administration server or another server in the Lotus Domino domain of the IBM Lotus Quickr servers.
- Click the Configuration tab.
- Click Server -> All Server Documents.
- Select the servers that you want to add to the cluster.
- Click Add to Cluster.
- When asked to choose the cluster you want to add the servers to, click Create New Cluster, and then click OK.
- Type the name for the new cluster, and click OK.
- Click Yes to add the servers to the cluster immediately, or click No to submit a request to the administration process to add the servers to the cluster.
- If you chose Yes in the previous step, the cluster information is added immediately to the Domino Directory of the server you used to create the cluster. If this server is not part of the new cluster, replicate the changes to one of the servers you added to the cluster. If you chose No in the previous step, perform the following steps:
- If you used a server other than the administration server to create the cluster, force replication between the server you used and the administration server so that the administration server receives the requested changes sooner.
- Force replication between the administration server and the cluster servers so the cluster servers receive all the changes sooner.
