what i have to configure in my system?(software)
how i have to move?
please help me with an example..
thanxs in advance.

Oracle AQ is used as a means of asynchronous communication between two (or more) Oracle databases.
Instead of communicating directly to the remote DB within your online application, you post a message into a local AQ queue (which would already have been setup for queue propagation) and Oracle takes care of making sure that it is made available at the destination (remote) AQ queue (it handles remote server not available and other transient errors automatically).
Once the message appears at the remote queue, it could be read and appropriate action performed (as indicated by message contents).

Propagation between queues in Oracle Advanced Queuing

We would like to connect two queues that reside in different database schemas/instances.
We try to use the propagation feature of Oracle to achieve this.
The queue-type is the same for both queues.
Enqueuing is done with a recipient list in order to set multiple local subscribers for the messages that are put onto the queue.
We would like to propagate between queues without changing the applications that write to originating queue and the other applications that read from the target queue.
During our research we only found ways where we need to change the application that writes onto the queue, which is not acceptable for us. Also the list of subscribers needs to be different based on the message.
Therefore I have the following question:
- is there a way to set up propagation between queues in a way where we don't need to modify the sending application?
- if not, is there a different way to connect two queues via a subscriber/consumer?

Oracle8i for Linux does have AQ, although I haven't evaluated it
yet. If you're still having trouble with the install, make sure
you get the patch. A quicker and easier way to get Oracle8i up
cheaply for evaluation is to download the NT version. I'm
evaluating Oracle8i for both Linux and NT and the NT version is
more stable.
I would really appreciate hearing about your experiences with AQ
on Oracle8 (8.0.4.3). I have several projects that we have been
considering using AQ with. Please send me an email and tell me
what problems / work-arounds you found.

Advanced Queue - Timezone Configuration

Dear Reader
If I create an advanced queue with the command "dbms_aqadm.create_queue_table", an entry in the table "system.aq$_queue_tables" results.
However, what is not clear to me is why the TIMEZONE column of this table is populated with 00:00, since this value neither correspond to the "dbtimezone" nor to the "sessiontimezone"?
"select dbtimezone, sessiontimezone from dual" returns
+02:00, CET
Thanks and regards,
Ulrik

Oracle JMS Advanced Queuing

Problems with Oracle JMS Advanced Queuing
Hello,
We have build an application using Advanced Queuing (database version 10.2.0.1.0). Everything works fine using PL/SQL. But when we try to send in messages through the Oracle JMS interface messages with less then 4000 bytes are stored in the queu table but the content of the message is not stored in one of the user data attributes.
Messages larger then 4000 bytes result in the following error:

Integration Oracle Advance Queue with OSB

We are doing integration for Oracle Advance Queue with OSB.
I created an AQ adapter in Jdev and generate the WSDL and XSD.
I imported both WSDL and XSD in OSB Project.
When i am configuring the business service and selecting the WSDl i am not able to select Binding and ports, is it due to any issue in WSDL?
Please help.

Oracle Advance Queue

I am using Jdev / oc4j as my server. I have a message driven bean created which is supposed to listen to an advance queue created in an oracle db. I am having a lot of trouble deploying the application. Is there an easier way out of editing the xml files and writing deployment descriptor? Please help.

Hi,
Just wondering if you were able to figure this out. I am too looking the samething. Basically MDB to listen on AQ, Can someone provide a simple example.
Thanks

FORMS APEX communication through Advanced Queuing

Hi there,
I have to prepare a proof of concept for an APEX application and the customer asked me if it is possible to establish a communication between FORMS and APEX besides using an URL call.
Would the usage of Advanced Queuing be a good practice for this asynchronous communication?
Regards
Tareq.

AQ will work on the Forms side, but not (or very complex) on the APEX side, because APEX is stateless (so no DB connection) and uses session pooling (you can hav another DB session for every roundtrip).
But maybe this will help:

JPA + Oracle Advanced Queues

Hi,
Has anyone managed to share a transaction between the toplink JPA implementation and the Oracle Advanced Queues interface (which uses jdbc; java.sql.connection) in a J2SE environment?
Running both in a J2EE environment is working fine, as both of them are using the JTA provided by OC4J.
I've been trying to use JOTM as a lightweight JTA provider, but without any success at this point. JPA is using the datasource created by jotm (that includes the jotm transactionmanager), but it seems like JTA transactions are being ignored by the EntityMaanger at this point...

Bert

Hi! I'm not a dev, but I know for sure ODP.NET does not support AQ. You might wanna have a look at Oracle Object for OLE (OO4O). It supports AQ and can be used in both VB.NET and C# through COM Interop. Of course, the performances will not be as good as ODP.NET tho.
Have a nice one.

Queries on Advanced Queuing in Oracle Database

Hi All,
We are new to Advanced Queuing.
We have a requirement wherein we need to implement Oracle AQ.
However upon some R&D, we got the basic idea of AQ.
But we would like to know on a broad level,
i.     The Purpose of enabling/Using AQ
ii.     Basic understanding on the different components of AQ like Creating Payload, Enqueue, Dequeue messages
iii.     Some high level understanding of the API’s – Which to use when and the purpose
iv.     Challenges faced
v.     Possible issues and Resolutions.
If anyone can help us with the above questions, it would be of great help.
Regards,
Shruti

Help me in usage of advanced queuing please ....

hello all,
we are developing a network based application in java servlets and oracle 8i as database at the servers.
to transfer data as costomised messages we are using ibm mq series as middle layer on top of tcp/ip.
we want to replace ibm mq series with oracle advanced queuing.
i could not find any details regarding this latest feature
i want to know what are the java packages available to use this feature and how to use them
are they similar to that of ibm.mq package
can i have some sample code about the usage of them ?
please send me the details ......
with regards,
prasad

Try the standard ORACLE documentation
Oracle8i Application Developers Guide - Advanced Queuing (AQ).
There are also some examples.

Advanced Queuing for Oracle / Dequeue failed

I'm using Oracle Advanced Queuing and OC4J with some MDBs. Unfortunately sometimes I have following exception:

All messages hang in my queue with READY state. I really don't know what is happening.
I have observed that when I run my MDB, but on the different machine, one message is consumed and the same exception arises.
Why Oracle cannot run dequeue process correctly?
best regards
Maciek

We had similar problems. Mostly the cause was incorrect message type (other than AQ$_JMS..., i. e. ancestor of "message" class) or incorrectly filled body of a message. For example, there seems to be a bug in AQ$_JMS_TEXT_MESSAGE object: you have to set at least one of varchar2 or CLOB in body of message. Otherwise, dequeue will fail, JMS assumes there is some text inside.
We are using 8i and 9i databases and messages are created using plain constructors (not methods from 9i, since code has to run on either version). I cannot recall any troubles using methods from 9i during researching, but there might be a bug somewhere.

Weblogic JMS bridge between Weblogic and oracle Advanced Queue
