Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Clustering servers for high availability and failover
You can provide failover and load balancing in your deployment by creating a cluster of multiple IBM® Sametime® servers of the same type. All Sametime servers can be clustered except for the Sametime System Console, and the Video MCU and TURN Server components of the Sametime Media Manager.
Clustering Sametime® Community Servers
IBM® Sametime® Community Server clusters provide redundancy, load balancing, and failover for community Connections. Sametime Community Servers are clustered as part of an IBM Domino® server cluster. A Sametime Community Server can belong to only one cluster.
Setting up the Sametime® Community Server cluster
Create a Domino® server cluster, then register Community Servers in the cluster.
Replicating the Domino® Directory across all servers in the cluster
Ensure that the IBM® Sametime® Community servers in the cluster are part of the same Domino® domain by registering them in the same Domino Directory and replicating the directory with all servers in the cluster.

Replicating the Domino Directory across all servers in the cluster

Ensure that the IBM® Sametime® Community servers in the cluster are part of the same Domino® domain by registering them in the same Domino Directory and replicating the directory with all servers in the cluster.

About this task

The Domino Directory must replicate to all Sametime Community Servers to ensure proper functioning of the IBM Domino servers on which Sametime is installed. This is a requirement even if you are maintaining the user community in an LDAP directory on a separate server that is not part of the cluster. For information about replicating the Domino Directory, see this topic in the Domino Administration documentation Scheduling replication of the Domino Directory.
