Configuration¶
Eclipse Cyclone DDS has various configuration parameters and comes with a default built-in configuration. To run an example, or any application that uses Eclipse Cyclone DDS for its data exchange, this default configuration is usually fine and no further action is required.
Configuration parameters for Eclipse CycloneDDS are expressed in XML and grouped together in a
single XML file. To use a custom XML configuration in an application, the CYCLONEDDS_URI
environment variable needs to be set prior to starting the application and pointed to the location
of the configuration file to be used.
set CYCLONEDDS_URI=file://%USERPROFILE%/CycloneDDS/my-config.xml
export CYCLONEDDS_URI="file://$HOME/CycloneDDS/my-config.xml"
The Eclipse CycloneDDS installation comes with a configuration file that corresponds to the default behaviour. You can modify it or add your using any text or XML editor, or using by using the Eclipse CycloneDDS Configurator tool, which provides context-sensitive help on available configuration parameters and their applicability.
One very important part of the configuration settings are the “tracing” settings: these allow letting Eclipse Cyclone DDS trace very detailed information to a file, and this includes the actual configuration settings in use, including all those that are set at the default. When editing configuration files by hand, this overview can be very useful. Increasing the Verbosity from “warning” to, e.g., “config” already suffices for getting this information written to the log.
