Cannot Trace¿¿¿¿¿¿¿ in Rule Watch mode after Requestor failure



Unable to Trace in the Rule Watch mode after Requestor failure.

Error Messages

Tracer session error: This rule RULENAME is being traced by operator tracetester from requestor - Please restart tracer

Steps to Reproduce

  1. Open a Pega Designer Studio session.
  2. Open a specific traceable rule. For example, activity.
  3. Select Trace on the Actions menu.
  4. Use the System Management Application (SMA) to identify and kill the requestor (using the 'Stop' button) to mimic the loss of the requestor session.
  5. Close the existing Designer Studio session.
  6. Open a Designer Studio session.
  7. Open the same rule mentioned in Step 2.
  8. Trace the rule again. The error message displays.
  9. Close and restart the Tracer multiple times (even a day later). The same error message displays. Therefore, it is not possible to trace the rule.
