Advanced agents do not run in the application



Advanced agents do not run in the application.

Error Messages

Fail:Not found

Steps to Reproduce

Open the Agents landing page from the Pega Admin Studio.  Verify the status of the agent.

Root Cause

In the user's application, the agent is configured with the 'Advanced' mode. The agent activity performed the RDB-Open on a class which returned 0 results when the database is queried. Therefore, the exception occurred.

For more information, refer to:

In the Advanced agents, the agent activity is responsible for both transactional and business processing. According to the functionality based on the agent activity status, the respective agent is disabled or is scheduled for the next run. In this use case, since the activity displays an error, the agent is disabled.


Perform either of the following local-changes:
  • Change the agent mode.
  • Manage the error scenarios in the agent activity while retaining the agent mode as Advanced.
