Katalyst: Analytical data not displayed after reopening experiment

Description
After successful data processing, analytical results may not appear when the user reopens the experiment. This behavior is typically caused by Arcus connection issues or MongoDB connection issues, both of which prevent Katalyst from retrieving and displaying processed analytical data.

Solution

• Confirm all components are connected from web app (Show User Menu à About).
• Arcus connection issues:
  1. Open the Katalyst WEB-INF application directory, for example: <TOMCAT>\WEBAPPS\KATALYST\WEB-INF, and open a command prompt.
  2. Run the environment checker specifying the CONFIG.JSON file location:
  3. java -jar Katalyst-environment-checker.jar "C:\kat_config\config.json"
  4. If Arcus connection issues are confirmed, ensure that the Arcus machine is running properly.
  5. If the Arcus machine itself appears healthy, run the OPERATION_CHECK.SH script on the Arcus machine and follow the required actions based on the script results.
• MongoDB connection issues:

1. Run Katalyst-environment-checker.jar again as described above to confirm MongoDB connectivity.
2. If MongoDB problems are detected and cannot be resolved through configuration, contact Technical Support.
