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® Proxy Servers
Configuring a cluster of IBM® Sametime® Proxy Servers involves several tasks, including synchronizing system clocks, configuring the cluster settings, and optionally deploying an IBM Load Balancer in front of the cluster.
Setting clocks on the servers to be clustered
Synchronize the system clocks on the servers to be clustered with an IBM® WebSphere® Application Server network deployment.

Setting clocks on the servers to be clustered

Synchronize the system clocks on the servers to be clustered with an IBM® WebSphere® Application Server network deployment.

About this task

This task is required to ensure that the servers can be federated to the deployment manager during creation of the cluster. Working on the Sametime® System Console, complete this task for every server that you will add to the cluster.

Procedure

For each server that will be added to the cluster, set the system clock to exactly the same time as the deployment manager's (the Sametime System Console) system clock.
(Optional) To set the system clock for an AIX® node, ensure you are logged in as the root user, then complete these steps:
1. Enter this command
  smitty date
2. Enter the time.
