JMS Propagation Remote Subscribers Enhanced Propagation Scheduling Capabilities Exception Handling During Propagation This feature enables applications to communicate with each other without having to be connected to the same database. AQ allows a remote subscriber, that is a subscriber at another database, to subscribe to a topic. When a message published to the topic meets the criterion of the remote subscriber, AQ will automatically propagate the message to the queue/topic at the remote database specified for the remote subscriber. The snapshot (job_queue) background process performs propagation. Propagation is performed using database links and Oracle Net Services. There are two ways to implement remote subscribers: The createRemoteSubscriber method can be used to create a remote subscriber to/on the topic. The remote subscriber is specified as an instance of the class AQjmsAgent. The AQjmsAgent has a name and an address. The address consists of a queue/topic and the database link (dblink) to the database of the subscriber. There are two kinds of remote subscribers: Case 1 The remote subscriber is a topic. This occurs when no name is specified for the remote subscriber in the AQjmsAgent object and the address is a topic. The message satisfying the subscriber’s subscription is propagated to the remote topic. The propagated message is now available to all the subscriptions of the remote topic that it satisfies. Case 2 Specify a specific remote recipient for the message. The remote subscription can be for a particular consumer at the remote database. If the name of the remote recipient is specified (in the AQjmsAgent object), then the message satisfying the subscription is propagated to the remote database for that recipient only. The recipient at the remote database uses the TopicReceiver interface to retrieve its messages. The remote subscription can also be for a point-to-point queue Example Scenario for Case 1 Assume the order entry application and Western region shipping application are on different databases, db1 and db2. Further assume that there is a dblink dblink_ 12-84 Oracle9i Application Developer’s Guide - Advanced Queuing
JMS Propagation oe_ws from database db1, the order entry database, to the western shipping database db2. The WS_bookedorders_topic at db2 is a remote subscriber to the OE_bookedorders_topic in db1. Example Scenario for Case 2 Assume the order entry application and Western region shipping application are on different databases, db1 and db2. Further assume that there is a dblink dblink_ oe_ws from the local order entry database db1 to the western shipping database db2. The agent "Priority" at WS_bookedorders_topic in db2 is a remote subscriber to the OE_bookedorders_topic in db1. Messages propagated to the WS_bookedorders_topic are for "Priority" only. public void remote_subscriber(TopicSession jms_session) { Topic topic; ObjectMessage obj_message; AQjmsAgent remote_sub; try { /* get a handle to the OE_bookedorders_topic */ topic = ((AQjmsSession)jms_session).getTopic("OE", "OE_bookedorders_topic"); /* create the remote subscriber, name unspecified and address * the topic WS_booked_orders_topic at db2 */ remote_sub = new AQjmsAgent(null, "WS.WS_bookedorders_topic@dblink_oe_ ws"); /* subscribe for western region orders */ ((AQjmsSession)jms_session).createRemoteSubscriber(topic, remote_sub, "Region = ’Western’ "); } catch (JMSException ex) { System.out.println("Exception :" + ex); } catch (java.sql.SQLException ex1) {System.out.println("SQL Exception :" + ex1); } } Database db2 - shipping database: The WS_booked_orders_topic has two subscribers, one for priority shipping and the other normal. The messages from the Order Entry database are propagated to the Shipping database and delivered to the correct subscriber. Priority orders have a message priority of 1.
