Root Cause

A defect or configuration issue in the operating environment.
The assembled entry for the Library function did not compile correctly; however, the entry was stored in the database table. As a result, authentication of the Pega Operator failed.


Perform the following local-change:
  1. Navigate to System Management Application (SMA) > Advanced > Virtual Rule Table Cache Management.
  2. Enter 'Rule-Declare-Expressions' in the Rule Class field.
  3. Enter '!.PXACTORSCOUNT!' in the Instance Name field.
  4. Click the 'Lookup Virtual Table Cache Detail' button to Lookup the activity.
  5. Click Reassemble candidates. The login initiates the reassembly.
