I have executed following command to start a user queue.
BEGIN
DBMS_AQADM.START_QUEUE('MY_USER.MY_QUEUE');
END;
Is it possible to check and confirm if this Queue is started or stopped using a query in Oracle 11g ?
You can check the USER or DBA queues view
SELECT name, enqueue_enabled, dequeue_enabled FROM dba_queues;
Basically, two YES's = started, two NO's = stopped.
