To modify the service configurations for load balancing:
In each service configuration file, change the <RepositoryURL> to point to localhost for the server repository URL. By default your server hostname will be configured in the RepositoryURL.
For example, the RepositoryURL should change to point to localhost from http://<Spectrum Hostname>:<Port>/RepositoryService/rmi to http://localhost:<Port>/RepositoryService/rmi. Ensure localhost can be resolved on the server.
