Error count and the last error column update criteria on the Scheduled job records



When are the “error count” and “last error columns” updated in the scheduled job records under sys trigger table



Under System scheduler application , we do have scheduled job records which have 2 columns for each record – Error count and Last error. Observe that these columns are not always populated for every Job failure. This solution talks about when these columns are updated for a scheduled Job failures





The columns are updated only when the error reported in the logs for a scheduled job is popped up by a Java throwable class like Java threads. Ex:


In the event a job failed catastrophically and an error bubbles up, the scheduler throw an event and re-queue. 
Note this is a departure from previous behavior that uses to set the state to error after two failures in a row


Based on the internal code, we can’t expect the above mentioned columns to get updated for every scheduled job failure
