Answer 1

Is there any message in alert log? Did you try to restart workers?There is no (error/warning/abnormal) message reported in alert log. Yes, it "Restarted" but again "Failed"
Can you check who access this view?(v$access)SQL> select * from v$access where object = 'FND_CONCURRENT_QUEUES';
no rows selected
Its not same error but please see:
