To ensure clustering works when you have both a Spectrum Technology Platform cluster and a Spatial cluster, changes are required to the Open Geospatial Consortium (OGC) services configuration files using Spectrum Spatial Manager: From the WFS, WMS, and WMTS settings pages, change the online resource (service) URL to the IP address and port of the load balancer. See the Spectrum Spatial Manager Guide in the Managing Spatial section of the Spectrum Spatial Guide for more information.
