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® Media Manager components
The IBM® Sametime® Media Manager includes several components. You can install the components separately and optionally cluster some of them.
Clustering Conference Manager components
Configuring a cluster of IBM® Sametime® Media Manager "Conference Manager" components involves several tasks, including synchronizing system clocks, configuring one or more WebSphere® proxy servers to operate with the cluster.
Setting up a WebSphere® proxy server for the cluster
Set up an IBM® WebSphere® proxy server for use with a cluster of IBM Sametime® servers. The proxy server can be hosted on a product node, or on a separate computer; it performs routing and caching tasks for the servers in the cluster.
(Optional) Adding a stand-alone WebSphere® proxy server to the cluster
Install a stand-alone IBM® WebSphere® proxy server for use with a cluster of IBM Sametime® servers.
Disabling the Sametime® application server from the new node
After you have federated a new IBM® Sametime® node to a cluster, disable the Sametime application server but leave the IBM WebSphere® proxy server intact.

Disabling the Sametime application server from the new node

After you have federated a new IBM® Sametime® node to a cluster, disable the Sametime application server but leave the IBM WebSphere® proxy server intact.

About this task

After the new node has been federated to the cluster, it can be managed by the cluster's deployment manager. Since the purpose of this new node is to provide a WebSphere proxy server, the Sametime product application is no longer needed on that node, and can be removed.

Procedure

On the cluster's deployment manager, log in to the Integrated Solutions Console as the WebSphere administrator.
Click Servers > WebSphere application servers.
In the list of servers, click the name of the new Sametime node.
At the beginning of the list, click the Delete button.
When prompted for confirmation, click OK.
Save the change by clicking the Save link the "Messages" box at the beginning of the page.
Verify that the server has been deleted by making sure it no longer appears in the list of servers.
