There are 2 configuration parameters for the web service in the file generic.xml in the config directory, ws_port and sqlite_db. ws_port defines the port on which the service will run and sqlite_db defines the location of the SQLite database file. By default a temporary file location is used by specifying TMP. If :memory: is used an in-memory SQLite database will be used, however the data in this location will not be stored after the webservice stops and is incompatible with functionality such as time profiling, for this reason an on-disk location is recommended.
