Planning Sametime features

This section describes best practices, requirements, tips, and things you should know when planning for instant messaging and presence services, meeting services, web client services, audio and video services, broadcast communities and persistent chat rooms, including IBM® Sametime® services in the extranet for remote users and customers. Included in this section are several sample topologies, everything from simple internal meetings to voice and video for intranet and extranet users.

For Sametime 9, servers can now share one IBM WebSphere® Application Server instance. In previous releases, you had to install a separate instance of WebSphere Application Server every time you installed an application server. Make sure that all servers you want to use can be resolved in DNS. If DNS is not available then list all fully qualified server names and IP addresses from all servers in the hosts file and publish this file to all servers. If you use Windows™ 2008 as Operating System, then you need to start all installations and configurations in Administrative mode. When installing more than one Sametime server on one computer, you may have port conflicts. Log into the Administrative Console to review the application servers and node agents to ensure that ports are unique.
