This chapter describes how to configure Oracle Communications Mobile Synchronization Gateway with multiple hosts.
See the installation procedures in "Installing Mobile Synchronization Gateway" if you want to add more Mobile Synchronization Gateway hosts to your deployment.
When you deploy multiple Mobile Synchronization Gateway front ends, a load balancer is necessary to distribute the load across the front-end hosts. You can base client-to-server affinity either on the Microsoft® Exchange ActiveSync clientid HTTP parameter or on the Authorization HTTP request header. The latter is considered the best practice for Microsoft® Exchange ActiveSync.
Multiple front-end hosts can alternatively be grouped together by using the Oracle GlassFish Server cluster functionality.
The Mobile Synchronization Gateway host connects to a primary back-end Unified Communications Suite host. You specify the primary back-end host during initial configuration.
When you add additional Unified Communications Suite hosts to your deployment, no additional configuration is required for Mobile Synchronization Gateway, unless you want to change the primary back-end Unified Communications Suite host.
