记录一次冷门技术oracle aq的使用

版本

oracle 11g

创建用户

-- 创建用户
create user testaq identified by 123456;
grant connect, resource to testaq;-- 创建aq所需要的权限
grant execute on dbms_aq to testaq;
grant execute on dbms_aqadm to testaq;
begindbms_aqadm.grant_system_privilege('enqueue_any', 'testaq', false);dbms_aqadm.grant_system_privilege('dequeue_any', 'testaq', false);
end;grant execute on dbms_aq to testaq;
grant resource to testaq;
grant connect to testaq;
grant execute any procedure to testaq;
grant aq_administrator_role to testaq;
grant aq_user_role to testaq;
grant execute on dbms_aqadm to testaq;
grant execute on dbms_aq to testaq;
grant execute on dbms_aqin to testaq;
grant create procedure to testaq;
grant create procedure to testaq with admin option;

创建列队表

begindbms_aqadm.create_queue_table(queue_table   => 'testaq.xml_queue_table',queue_payload_type => 'SYS.XMLTYPE',multiple_consumers => false);
end;

创建列队及启动队列

begindbms_aqadm.create_queue (queue_name  => 'testaq.xml_queue',queue_table => 'testaq.xml_queue_table');dbms_aqadm.start_queue(queue_name  =>  'testaq.xml_queue');
end;

停止及删除队列

begindbms_aqadm.stop_queue (queue_name => 'testaq.xml_queue');dbms_aqadm.drop_queue (queue_name => 'testaq.xml_queue');dbms_aqadm.drop_queue_table (queue_table => 'testaq.xml_queue_table');
end;

发送消息

declarer_enqueue_options DBMS_AQ.ENQUEUE_OPTIONS_T;r_message_properties DBMS_AQ.MESSAGE_PROPERTIES_T;v_message_handle RAW(16);o_payload testaq.test_queue_type;
begino_payload := testaq.test_queue_type('<ROOT><ROWSET><ROW><APPLYNO>test</APPLYNO></ROW></ROWSET></ROOT>');dbms_aq.enqueue(queue_name  => 'testaq.test_queue',enqueue_options => r_enqueue_options,message_properties => r_message_properties,payload => o_payload,msgid => v_message_handle);commit;
end;
