The Heimdall server operates using a system call Spring Boot, which provides the basic infrastructure for managing connectivity, api calls, etc. As such, settings that apply to Spring Boot are used to configure aspects of behavior such as the TCP port used as well as TLS configuration

Changing TCP port

To change the TCP port of the server, in the install directory, create a file named "application.properties" and in it, add the following line, adjusting for the desired tcp port

server.port=8087 # Server HTTP port.

When connecting to an alternate port, the driver configuration will also need to be adjusted to account for this.

When configuring a proxy directly, append : to the hostname in the JDBC URL.
