The following diagram outlines the components required to support the High Availability Disaster Recovery module. Each site employs a dual blue-green environment where blue represents one environment and green the other. The NMS Monitor is deployed as a dedicated managed server on the WebLogic 14.1.2 server and communicates with the NMS Agent and database of each NMS environment. Each NMS environment (blue/green) has its own NMS Agent that monitors the NMS Services in that environment.
