Oracle Advanced Queuing Series: 1. Create Message Type, AQ Table and Queue

Welcome to the first part of the series “Oracle Advanced Queuing”.

We start with the basic elements of Oracle Advanced Queuing:
the message type, the queue table and finally the queue.

  1. Create a Type for your messages:
    CREATE TYPE my_queue_typ  AS OBJECT(message_text VARCHAR2(4000));
  2. Create an AQ Table based on your type:
    EXEC DBMS_AQADM.CREATE_QUEUE_TABLE('my_queue_table', 'my_queue_type');
  3. Create a Message Queue with your table:
    EXEC DBMS_AQADM.CREATE_QUEUE('my_queue', 'my_queue_table');
  4. Start the queue:
    EXEC DBMS_AQADM.START_QUEUE('my_queue');
