X-list: oracle-l Return-Path: Subject: Re: AQ Vs Streams From: Sriram Kumar Message-id: c515faee0601090639o6f480626j8ab9e04e1390b63e@mail.gmail.com Date: 2006-01-09 15:39:11 Hi, We have done some thing like this. I admit that I am not an in expert in this area. The design is like this. 1. Application Enques into AQ. 2. Can attach a Message Driven Beans(MDB) listening on the queue. Guess this should happen over a AQ-JMS bridge By this the bean would be invoked whenever there is a enque event and polling would not happen. Hope this helps Best Regards Sriram Kumar On 1/4/06, Subbiah, Nagarajan wrote: > > > Thanks, All. > > Here is the design we are trying to implement. > > Source Application enqueues the message to the source queue.
