This article describes a worked example detailing the cluster process for a two-node horizontal cluster in an IBM® Sametime® 8.5.2 Gateway environment, in which both the Deployment Manager and the Sametime Gateway Primary node are installed on a single server, with the Secondary Gateway node on a separate server.
The article also discusses the installation of the XMPP server and the installation and configuration of the Sametime Gateway Session Initiation Protocol (SIP) proxy. In this case the SIP proxy is to be implemented on the same server as the Secondary Gateway node.
