Example of using Temporary Queue

**Plz tell how temporary queue can be created and used by sender and receiver to communicate with each other.
**Will it will be feasible if single queue is used by clients with ID attached with each message.

Problem Using Temporary Queue

          I send an object message to a queue with the JMSReplyTo set to a temporay queue the
          client uses to sit and listen for a response. When the MDB tries to do a lookup
          on the temporary queue to send a response, it gives me the following error:
          javax.naming.NameNotFoundException: Unable to resolve eDailiesJMSServer.TemporaryQueue56
          Resolved: '' Unresolved:'eDailiesJMSServer' ; remaining name 'TemporaryQueue56'
          <<no stack trace available>>
          I checked in the WebLogic console while the client was still listening for a response
          and it shows a temporay queue up and running called eDailiesJMSServer.TemporaryQueue56
          Is there something else I should do to resolve the JNDI name? I used the following
          code in the MDB to get the temporary queue name:
          (Queue)msg.getJMSReplyTo()).getQueueName()
          Any ideas?


You already have a reference to the Queue from msg.getJMSReplyTo(). There
          should be no need to look it up again.
          I don't think you are supposed to be able to look up a temporary queue in
          this fashion anyway.

Why do the LabVIEW examples that use the queue design have one loop in the top level and all the others as subvis?

Specifically the Weather Monitor example under connectivity/Web Services and the FPGA design examples.
There are several parallel loops. One of the parallel loops will be in the top level VI. The others are all in sub-VIs. After the third example I was looking at it seemed obvious this was being done as a standard, but I don't know why it matters.
Why not all of them as SubVIs? Why not all of them as top level loops? (Well OK maybe not that one.)

For me, it depends on what is happening in the parallel loops. When I have modules that just need to run in parallel with the main loop, it helps reusability to have it a a subVI call. I can then just copy that library to another project and use it.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

How to bind Temporary Queue to Context in FioranoMQ

I have two JMS clients sending messages to each other via FioranoMQ.
And one client creates a temporary queue, for example
Temporary Queue auction1Queue = qSession.createTemporaryQueue();
My question is how to bind this auction1Queue to Context? so that the client on the side can lookup
I don't use the usual way of set/getJMSReplyTo() to message because it will change the logic of my program.
With SonicMQ, I just simply bind it like this
jndi.bind("auction1", auction1Queue);
then the other side just need to jndi.lookup("auction1")
and with ActiveMQ it is even simpler
Both side just need to lookup for the same name like that
jndi.lookup("dynamicQueues/auction1");
http://activemq.apache.org/jndi-support.html
But FioranoMQ does not support both of the above operations.
I don't really know how to do the same thing with FioranoMQ.
Hope that somebody can help me.
Thank you very much

How to look up for temporary queue by using temporary queue name using JNDI context. I am getting lookup faild error" for temporary queue. While trying to bind this temporary queue name to jndi , it is throwing an exception as: notsupported exception. I am using ActiveMQ 5.2.
See below sample code...
tq = session.createTemporaryQueue();
jndiContext.bind("queue.MyTempQueue",tq);

What port numbers are used when creating temporary queues

Using the following code as an example, what port(s) are used when creating temporary queues? Is it a range of ports? Is it random? And is it configurable? If you have any insight on this, please let me know. Thanks.
QueueConnection con = connectionFactory.createQueueConnection();
QueueSession session = con.createQueueSession(true, Session.AUTO_ACKNOWLEDGE);
TemporaryQueue replyQueue = session.createTemporaryQueue();

The only ports I know about are the defaults ports:
JMS 7676
IIOP 3700
Are these the only ports that are used, even for temporary queues?

Temporary queue - what am I doing wrong?

I have two different apps - one server and many clients, both are working with OpenMQ 4.2 on SP1 Vista x86.
Conception is:
1. Server has an one permanent queue to whom clients send auth requests.
2. Each time client prepares authorization request it creates temporary queue, where response from server should arrive - one queue per each client.
3. Name of this temporary queue is attached to authorization request.
But it doesn't work =((((((((
Piece of code on client dedicated to temp queue:
dataQueue = session.createTemporaryQueue();
dataQueueName = dataQueue.getQueueName();then DataQueueName is being sent to server as simple String message (something like temporary_destination://queue/***.***.***.***/61253/1 )property where it tries to use this queue:
// processing received message...
dataQueue = new com.sun.messaging.Queue(receivedString);But it doesn't work, Connection not created exception occurs.
What am I doing wrong?
Thanks to everybody for your future answers.

thanks for your answer!
I've tried to work with autocreated queues as you wrote and it works, great =)
but I have a problem when adopting your example
Queue tmp = m.getJMSReplyTo();
there is type mismatch here, tmp is an +com.sun.messaging.Queue+ object, but method +getJMSReplyTo()+ returns +javax.jms.Destination+ =(

How to use Temporary Table in PL-SQL

In MySQL there is no Temporary table concept.
So for intermediate calculation I have created a table as below
create table SequenceTempTable
SessionId VARCHAR(50),
Sequence VARCHAR(500),
CreatedDate DATE
) ENGINE=MEMORY;
Whenever I invoke a SP, I load the data into SequenceTempTable using Session Id as below
CREATE PROCEDURE `GetSequence`(
IN Start_Date VARCHAR(25),
IN End_Date VARCHAR(25)
BEGIN
SELECT UUID() INTO v_SessionId;
INSERT INTO SequenceTempTable values (v_SessionId,'1,2,5,3',now());
required code
DELETE FROM SequenceTempTable WHERE SessionId = v_SessionId;
COMMIT;
END;
i.e. I have created a table as temporary table (created once),
and load the data using Session Id and once session specific intermediate computation done,
I deleted the session specific data.
Could you give me examples of How to use Temporary table in PL-SQL code with respect to my above example.
Because I have gone through creating Temporary table but I stuck with use in PL-SQL. I mean to say Is there any need of creating table in advance before invoking SP.
And one more thing as in MySQL temp table I created which is using MEMORY engine i.e. this table will always be in MEMORY so there is no need of writing data on disk.
Regards
Sanjeev

Hi Sanjeev
Read about GTT here
http://www.oracle-base.com/articles/8i/TemporaryTables.php
GTT always contains just session specific data. \
In case you want to use the GTT in the same session again you can use option
ON COMMIT PRESERVE ROWS;
Or if it is used just once in the session use can use
ON COMMIT DELETE ROWS;
Do remember that for GTT the data of one session can not be accessed in other session.
Also you can go away with Delete from GTT if not used again in same session.

When to use IN Queue and When to use OUT Queue

The architecture that we have is Client publishes the EDI 272 data to FTPS Server. We have ESB configured to pick the EDI data from FTP location, construct the B2B Header message and send to B2B. The B2B translates the EDI raw data to EDI XML. BPEL reads the EDI XML data from B2B. I have doubt here in using the IP_IN_QUEUE and IP_OUT_QUEUE. As per my understanding, IP_IN_QUEUE is used for messages inbound to B2B and IP_OUT_QUEUE is used for messages going out of B2B. If this is correct, ESB module would publish to IP_IN_QUEUE and BPEL would pick from IP_OUT_QUEUE.
I'm confused here because I read few examples in which the queues were used other way around.
Kindly clarify whether the usage of IN and OUT queus are correct.
Thanks,
Mani

HI Mani,
When B2B receives an inbound message from trading partner, it will send to IP_IN_QUEUE.
When Back application wants to send a message to B2B, Backend application has to send the message to IP_OUT_QUEUE. B2B picks up the message from IP_OUT_QUEUE and send it to trading partner.
The above mentioned queues are shipped with the product. However, users can can create there own queues.
Thanks and Reagrds,
Prasanna

Using temporary tables in stored procedures

Suppose that I have created a temporary table in a stored procedure using an "EXECUTE IMMEDIATE" statement. When I compile the procedure, that table is not created yet, so the compiler says that the table does not exist.
What is the way of using temporary tables in stored procedures?

It's a good practice to avoid using DDL statements being executed from stored procedures. "Truncate Table" via dynamic SQL from stored procedure is a different story and is useful in DSS environments.
But if you insist on "creating" tables using Dynamic SQL from Stored Procedures then you must also embed your DML statements in Dynamic SQL to avoid compilation errors.
Example:
Create or Replace Procedure Proc_TestDynamicSQL is
Begin
Execute Immediate 'Create table myTable as select * from user_tables' ;
Execute Immediate 'Update myTable set table_name = ''Test'' ' ; --two single quotes before and after the string "Test"
End;
In this case, Oracle wouldn't care about the table references during compilation.

How to use temporary database?

hi
i am using timesten as cachedb for oracle database。i have some problem about how to use temporary database？
1） what's the difference between temporary and non-temporary database，if i use awt cache group,then timesten will automatically replicate all change to oracle database , even if timesten crashed，i can set up another timesten quickly，no data loss？
2）since all data is in oracle database，does timesten‘s transaction log and checkpoint file useful ? does timesten need backup ?

Temporary databases have very limited usefullness; you can't use them with replication or caching for example. They are a very 'niche' use case; I'd recommend that you avoid them for mainstream use.
TimesTen checkpoiint and transaction log files are always required (except for Temporary database which do not have checkpoint files but do have log files).

How to use a queue with dynamic data

When using a collector I have found that it significantly slows down my loop times. I am using LabView7.1 on a Dell PC with Windows XP. If I use a queue with dynamic data do you think that will require less of my processor and allow for faster loop speeds?
I have created a queue using dynamic data in one loop and I want to retrieve all available samples each iteration in a slower loop. If I use the flush queue I get a 1d array of dynamic data. What is the best way to convert the 1d array of dynamic data so that the array of dynamic data is consolidated back into a single dynamic data type? Any help would be much appreciated.

Hi Dennis,
You could for instance wire the array to an auto-indexed for loop. I attach an example. I assume you wish to concatenate the arrays a singel waveform.
Hope it helps,

Problem with temporary queues

Hi,
          I've setup a template for temporary queues in the weblogic console (8.1SP4). However, I'm getting an exception when trying to destroy the queue after use. This doesn't happen with other JMS providers, so is there something special to Weblogic about temp queues? Is there a specific option that needs to be set in the template?

If there are still application receivers on the temporary destination, the call will fail. (As specified in the JMS javadoc.) Perhaps this is the reason for the exception? In which case the application needs to close its receivers first.

When Broker Restarts None of the Temporary Queues Are Created

Somehow when the broker restarts none of the temporary queues are getting recreated. The queues were created successfully the 1st time and the applications were happily exchanging messages. Things just fall apart when the broker restarts.
I'm able to reproduce this problem consistently by doing the following:
1. Start imqbrokerd (mq start)
2. Start client application
3. Shutdown imbrokerd (mq stop)
4. Start imqbrokerd (mq start)
After the producers in the client application have reconnected the following messages are displayed in the console. I'm only able to get the client app to work again is if I restart the client apps.

I also tried versions 4.4 and 4.2 and received the same behavior :(

The application is inside an app server but we're not using a resource adapter as we're using Spring and Camel to hide the JMS details. Spring (JMSComponent) manages the connection directly. (We current don't have any JMS connection pooling as well.)
<bean id="jmsTransactionManager" class="org.springframework.jms.connection.JmsTransactionManager">

</props>
</property>
</bean>
<bean id="jms" class="org.apache.camel.component.jms.JmsComponent">
<property name="connectionFactory" ref="jmsConnectionFactory" />
</bean>
I'm going to write a very basic producer using Spring without using Camel and see if I'll get the same behavior. I'd like to see if the way Camel uses JMS is what's making OpenMQ broker to deny creation of temporary queues.
Thanks,
Jeff

Cannot receive message on temporary queue

I am executing the following code in a web application.
          It is sending a message to a JMS queue. The MDB
          listening to that queue processes the message
          and posts a reply to the temporary queue specified in
          the JMS Reply to field. The queue browser code below
          shows that the message is in the queue, but the receive
          times out and returns null. My question is why can't the
          receiver get the message?
          Am I missing something?

MDBs responding via Temporary Queue

Hello,
I've been attempting to get this working in test code, but i seem to be missing something. I want a message producer to send a message to an administered queue, have the message processed by a Message Driven Bean, and have the bean post a response back to a temporary queue that was setup in the original producer. All over the net i find statements that this can be done and is reasonably normal, but i have not found a single code snippet to this effect, nor can i apparently get it to work on my own. I am using JMS with J2EE 1.3 on websphere 5.0.
Within the message producer, i create the temporary queue and pass it in the JMSReplyTo field.
<code>
TemporaryQueue tempq = queueSession.createTemporaryQueue();
message.setText("Temporary Queue Test Message");
message.setJMSReplyTo(tempq);
queueSender.send(message);
</code>
The MDB sees the message and onMessage is called normally. From within the MDB code, i have the temporary queue object (i print out the name of the queue in the message ReplyTo field with toString() to confirm) and i have the MDB context from getMessageDrivenContext() supplied by javax.ejb. Unfortunately, javax.ejb.MessageDrivenContext is not the same or similar to javax.naming.Context.
To send a message, i need the send() method from the QueueSender interface, which is generated from the QueueSession interface, which is generated from the QueueConnection interface, which is generated from a QueueConnectionFactory, and is ultimately reliant upon javax.naming.Context. So, i have the (temporary) queue object, but see no method to put a message on it for consumption by the creator of the temporary queue. (messages on temporary queues can only be consumed by the creator of said queue. if no other producer can use it, too, perhaps i am missing the point on temporary queues)
I can easily get the MDB to fire off messages to other administered queues. How do i get it to respond with a message on a temporary queue?
Could somebody please enlighten me?
thanks,
cam

Thanks Andreas, your answer sent me off on new trails to read, but something is still missing. I hope that you (or anybody else) is able to see what i do not.
Your code was J2EE 1.4 (beta), but Websphere 5.0 still uses J2EE 1.3.1. I was able to translate most of your code back to the older form but some doesn't fit, which may be part of my problem (as shown below).
I have connection factories and queues already setup on the server. they work fine as far as all other non-temporary queue usage is concerned.
Using your code, here's some of the problems i have crossed while trying to sort this out
public void onMessage(Message inMessage)
Destination dest = (Destination) ctx.lookup("jms/t0");
MessageProducer producer = session.createProducer(dest);
producer.send(msg);
}My first question is how are you looking up a temporary (i.e. dynamically created) queue with some hard-coded string ("jms/t0")? I assume that your string was meant to be arbitrary but it must still represent the destination, which is the temporary queue that doesn't have a hardcodable name (AFAIK). I have tried using the name inMessage.getJMSReplyTo().toString(), which in my case gives me "queue://WAS_localhost_server1/AMQ.10000009?persistence=1", but this only throws a NamingException (not found) when trying to do a lookup() on it.
If you already had the Destination object from inMessage.getJMSReplyTo().toString(), why would you bother to go through a String lookup just to get the object again? (for use in the createProducer() call)
To get past the above naming exception, i commented out the Destination getting line and used the object from the getJMSReplyTo() message method. In 1.3.1, the equivalent Producer line looks like:
QueueSender producer = session.createSender(replyTo);which is pretty much like what i already had. Unfortunately, an error is reported that it is unable to open the specified queue. (J2CA0056I: The Connection Manager received a fatal connection error from the Resource Adaptor for resource JMS$MyMDBConnectionFactory$JMSManagedConnection@580144656. The exception which was received is MQJMS2008: failed to open MQ queue)
I double checked to make sure both the creator of the temporary queue and the MDB were both using the same administered Connection Factory. They are. I don't know if it's relevant.
Any further ideas?
Thanks,
cam
