Advanced Queuing - Oracle

Propagation Features
Propagation Using HTTP
PL/SQL (DBMS_AQADM Package): Example Code
declare
subscriber sys.aq$_agent;
begin
subscriber :=sys.aq$_agent('West_Shipping','WS.WS_bookedorders_topic',null);
dbms_aqadm.add_subscriber(queue_name => 'OE.OE_bookedorders_topic',
subscriber => subscriber,
rule => 'tab.user_data.orderregion =''WESTERN''
AND tab.user_data.ordertype != ''RUSH''',
transformation => 'OE.OE2WS');
end;
Visual Basic (OO4O): Example Code

In Oracle9i, you can set up Advanced Queuing propagation over HTTP and HTTPS
(HTTP over SSL). HTTP propagation uses the Internet access infrastructure and
requires that the AQ servlet that connects to the destination database be deployed.
The database link must be created with the connect string indicating the Web server
address and port and indicating HTTP as the protocol. The source database must be
created for running Java and XML. Otherwise, the setup for HTTP propagation is
more or less the same as Oracle Net Services (formerly Net8) propagation.
Scenario
In the BooksOnLine example, messages in the OE_bookedorders_que are
propagated to different shipping sites. For the purpose of this scenario, the Western
Shipping application is running on another database, 'dest-db' and we will
propagate to WS_bookedorders_que.
Propagation Setup
1. Deploy the AQ Servlet.
HTTP propagation depends on Internet access to the destination database.
Create a class AQPropServlet that extends the AQxmlServlet.
