We are facing an issue in our ThingWorx 9.3 Production environment where Timer Things and Schedulers are not executing, while the same configuration works correctly in other environments.

Environment

  • ThingWorx Version: 9.3
  • License: Valid until 2027
  • Issue specific to production environment

Validation Performed

  • Verified Timer Thing is enabled.
  • Verified runAsUser is set to Administrator.
  • Verified subscriptions are enabled.
  • Compared Timer Thing XML/configuration between working (test) and non-working (production) environments; no significant differences found.
  • Created a new test Timer Thing with a simple logging subscription; it did not trigger.
  • Created a test Scheduler; it also did not execute.
  • Restarted the ThingWorx server.
  • Verified license status through Licensing Subsystem.

Timers need not only to be “enabled” from a thing lifecycle perspective, they also need to be enabled in a sense of triggering. run the IsEnabled service to check, if not already. Check timezone setting of machine and TWX server.

 

Increase logging and check log file. Check articles

Can you check in ApplicationLog for logs regarding your timer and scheduler name? It might complain what’s wrong with it
