On the Sentinel server, hostname changes are automatically updated during run time or during the installation. If the server does not properly function after a hostname update, you must manually verify the following:
All jnlp files and the configuration.xml file are updated on Sentinel restart.
The hostname entry in the sentinel_host database table is updated.
All references to the local loop (localhost or 127.0.0.1) in the <install_directory>/config/configuration.xml file remain unaffected.
