Unable to save data into exposed columns on some nodes

SA-49098

Summary



Unable to save work object data to exposed columns on some nodes despite optimized properties.


Error Messages



Not Applicable


Steps to Reproduce

  1. Add columns manually to a table directly in the database.
  2. Create properties with the same name as the new columns.
  3. Save the objects without restarting the instance.


Root Cause



A software use or operation error.

Some application nodes were not restarted after the database schema was changed.



Resolution



Here’s the explanation for the reported behavior:

As Pega only reads database schema metadata during engine start up, when changes are made to the schema, all instances connected to the database must be restarted.
