====== 16.6 Node Execution ======

[[fxdemo:04-part:16-phase-0-script-and-execution-model:start | Go To Phase 0 Script and Execution Model ]]

Phase 0 may include scripts that start individual implementation participants.

A node execution script starts a selected implementation participant, applies required configuration, identifies the FX logical [[fxdemo:99_part_annexes:annex-b-terms-and-definitions:n:node|Node]] or Node Role being realized, and records startup information according to the Phase 0 logging and health-reporting conventions.

A node execution script should identify:

  - Implementation participant to start
  - FX logical Node or Node Role realized by that participant
  - Required configuration file or configuration source
  - Required DDS Topic or QoS configuration context
  - Required generated types
  - Expected startup status
  - Expected logging behavior
  - Expected status-reporting behavior
  - Error-handling behavior when startup fails

The script does not redefine the implementation participant or the FX logical Node. It starts the selected artifact according to the implementation baseline.
