Planning
Planning is critical to a successful deployment. Many deployment problems, growth problems, and capacity problems occur because not enough time is taken to carefully plan a deployment. Plan your IBM® Sametime® installation by determining features needed, reviewing system requirements, determining capacity requirements, and the servers and computers needed for your deployment.
System and infrastructure requirements
Sametime® system and infrastructure requirements include network planning, policy planning, password and parameter planning and planning for single sign-on.
Ports
IBM® Sametime® uses a number of ports. There are ports for connecting server to servers, clients to servers, and WebSphere Application Server ports to configure. The topics in this section list the default ports and their uses, and ports to open in firewalls. A range of ports means that the application can select any port in that range if one or more of those ports are already in use by other applications.
Ports that must be free before installation
Before you install any of the servers listed, you must be sure that the hard-coded ports listed in the table are free on that computer or you will have port conflicts.
