Install and configure IBM
® Load Balancer to distribute workload among a cluster of these type of servers: Sametime
® Proxy Server, Sametime
Meeting Server, Media Manager Conference Manager, or Media Manager SIP Proxy and Registrar, and Sametime
Before you begin
Create the cluster of servers first. Then configure the cluster and then start the Deployment Manager (the Sametime
System Console) as well as all node agents and application servers in the cluster.
Load Balancer is not available on IBM
i, but you can deploy it on a server running a different operating system for use with a Sametime
deployment hosted on IBM
Load Balancer is not required for a Sametime
clustered deployment; you can use any load-balancing mechanism that supports HTTP session affinity so that a user is repeatedly routed to the same server during a single session. IBM
Load Balancer is included in the Sametime
package with the other IBM WebSphere
- Download IBM Load Balancer onto the server where you will install it:
- Open this release's Download document at the following web address:
- Locate the appropriate IBM WebSphere Edge server component in the document's listing, then download the packages labelled with the corresponding part numbers to the system on which you are installing. Note that there are separate versions of Load Balancer for IPv4-only addressing and for IPv4-and-IPv6 dual addressing,
- Navigate to the folder where you stored the downloaded files, locate the folder for IBM Load Balancer, and start the installation program.
- After you have installed IBM Load Balancer, configure two static IP addresses for it:
- Non-Forwarding Address: The NFA is the address of the server itself. It is used for logging in and administering the load balancer.
- Cluster Address: This is the address by which clients and other servers will access the cluster. It must be DNS-resolvable.

For example, suppose your cluster contains two nodes, and you configure an IBM
Load Balancer for the cluster. Your IP addresses will look like this:
