ORA-16675: database instance restart required for property value modification to take effect
Cause:
One or more properties that correspond to static initialization parameters were modified, but the database instances were not restarted. Or, a static initialization parameter that corresponds to a broker property was modified using an ALTER SYSTEM SQL*Plus statement.
Action:
Restart the database instances for the modified property values to take effect. If the error persists after having restarted the instance, use the DGMGRL CLI or Enterprise Manager to modify the property the static initialization parameter corresponds to.
