single node configuration can be useful during development, but would not normally be used when your application is deployed.

When creating the configuration used by an application and defining the nodes where a facility has its frontends, routers, and backends, the setup must also define which nodes will have journal files. Each backend in an RTR configuration must have a journal file to capture transactions when other nodes are unavailable. When applications are deployed, often the backend is separated from the frontend and router, as shown in Figure 1–10.
