Hi all,
Can a MDB listen to multiple queues. If so how will be the deployment descriptor
Thanks

  • Multiple queue vs single queue - peformance

    Hi All,
    Could pls throw some light on the following design.
    Currenty, We have more than 100 queues and for each there is a different MDB to receive the message.Now, somehow we made a single instance of same MDB listen to all these queues by looking at the input message. The requiement now is, is it possible to club all the queues into single queue as it's asynchronous messaging. The receiver may also try write into the same queue at the end of message processing.If so, how would be performance. Is this performance better than having multiple queues?.
    The message are expecting to be 25 k/day in the queue. And we are using Weblogic server.
    Please let me know if you need more details.
    Thanks
    Srinath

    You could try to use selectors to assign messages to particular MDBs. This way you off load some of the work on the broker but selectors by their nature usually have an impact on broker's performance. It all depends on your application, your expectations, size and the rate of your messages, how long it takes to process them on the client side. There is no simple answer in this case. You would have to test some scenarios to come up with a best solution that fits your requirements. Having said that I personally believe that some degree of partitioning of your queue could be beneficial. On a heavily loaded system it may increase the concurrency of the system and its resilience, particularly if you place the queues in different brokers. Try to imagine your broker as if it was a DB server with just one table (I'm not sure if this is the best analogy but I can't think about anything else at the moment).

  • Single OSB Proxy Service Listening to multiple MQs

    Hi All,
    I am using OSB 11.1.1.5 and Websphere MQ version 6.
    I have a requirement to make a single proxy service to listen to multiple MQs. Is this possible?
    If yes, please help. If no, what is the work around?
    Regards,
    Karthik

    One proxy service can listen and consume messages from one MQ only as you can mention only one Endpoing URI with MQ transport in OSB.
    Work around is to create as many proxy services as you have MQ queues and create one common proxy service with local transport and let all MQ proxies call the common proxy service over local transport.

  • Multiple Queue Assignment for Integration Process - PI 7.11

    Hi,
    I am trying to configure multiple Queues for an Integration Process.
    The Integration Process is straight forward, except for a Asynchronous Request Response pattern with correlation. (A asynch send step - immediately followed by a asynchronous receive step with Correlation)
    I have done the following
    1) In IR set the Queue as Multiple - Content Specific
    2) In SWF_INB_CONF transaction reconfigured Multiple Queues - Content Specific without buffering
    But when I trigger the message, the message is not at all triggering/entering the Integration Process. The error message is BPE Internal Failure.
    But if I reconfigure the IP as One Configurable Queue & "Without Buffering", it is working. But we want multiple queues assigned to this Process.
    Thanks in advance.
    Regards,
    Sudharshan N A

    Bjoern, there are blogs/wikis available which should be searched before a question is asked on forum. The information you need is quite basic one and I will therefore lock this thread.

  • Use 1 listener for multiple database in a server

    hi guys,
    just want to check whether this is the right way to configure my Listener.ORA . I am using 1 listener.ora to listen for incoming request connection from remote client. There are multiple databases installed in a server.
    LISTENER =
    (DESCRIPTION_LIST =
    (DESCRIPTION =
    (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = ora03)(PORT = 1521))
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = O11R2)
    (ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db_1)
    (SID_NAME = O11R2)
    SID_LIST_LISTENER =
    (SID_LIST =
    (SID_DESC =
    (GLOBAL_DBNAME = O10G)
    (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
    (SID_NAME = O10G)
    )sorry i am reading about it so did not install another database to test out. Just thinking in the line that it mention that the list of SID is refering to the multiple database that is installed in a server and i am using 1 listener.
    Please further advice.

    )Please use as above. You can have one listener for multiple databases.right right so it the pattern goes like this:
    SID_LIST_LISTENER =
         (SID_LIST =
              (SID_DESC =
              (GLOBAL_DBNAME = AAAA)

  • How do I use same MDB for multiple Queues? Deployment ?

              Here is what I am trying to do

              solution.
              Is there any other work around?
              I want to add queues in future as and when needed. I don't want to modify the

              to add another queue for the message-driven-bean. Is is possible to use some kind

  • How to implement multiple queues in one circular buffer?

    Spoiler (Highlight to read)
    Recently I have successfully shared data of 2D array among different vis in a project, using circular buffer.
    However, there is only one circular buffer allowed in one project for one data type.
    I want different vis, running and getting data from circular buffer in different speed, all getting data as a queue from circular buffer. Like the circular buffer's read continuous mode.
    The problem is that after a vi reads in continuous mode, the read data is deleted from the circular buffer. Then other vis can not use them any more and can not keep track where they should begin to read again.
    So if it is possible that there are multiple pointers or queues in circular buffer to keep track the progress of different vis, and data only update when it gets input from DAQ but not deleted when read?

    THe last time I wrote a multi-subscriber cirular buffer was in LV 6. Since then I have found that polymorphic queues perform much better so I now use multiple queues. One queue for each subscriber of the data. The subscribers are then responsible for maintaining their own histories.
    So just use multiple queues.

  • One Listener for multiple things?

    Is is OK to use on listener for multiple events on the same object?
    I have this for a FLV component and it seems to work. Is that legit?
    var listenerObject:Object = new Object();
    listenerObject.complete = function(eventObject:Object):Void {
        trace("End of this video!!!!");
    myVideo.addEventListener("complete", listenerObject);
    listenerObject.stateChange = function(eventObject:Object):Void {
        trace("stateChange just occurd!!!");
    myVideo.addEventListener("stateChange", listenerObject);
    Thanks a lot for any info!!!

    Yup no problem. However I would group my listener object properties close together.
    listenerObject.complete=function(e:Event){
    // blah blah
    listenObject.progress=function(e:Event){
    // blah blah blah
    And so on. If they end up separated you most likely will forget over the course of time and then when you come back you might delete the object after you use it for one event and forget that it has others.

  • Http to Abap Proxy communication with multiple queues generation in Recevr

    Dear SDNs,
    I need some help in the following scenario, appreciate your suggestions and help .
    I am receiving the messages from sender to PI on http posting, from PI  I am sending the message to SAP system using receiver xi communication channel ( receiver is abap proxy).
    Sender will send the messages in QOS=EOIO, QUEueID=XXXt_100 etc  parameters, when large volumes cases, it is getting delayed to process it using a single queue.
    We are thinking to dynamically  generate multiple queues in PI and send the same queue ids to receiver SAP system to process all the messages quickly in SAP System also.
    Help /Clarifications needed:
    1. XI receiver communication channel in  pi  does not provide any options to generate dynamic queue id based on payload content (using dynamic configuration) and sent it to SAP.
    2. Module Tab in receiver communication channel also got disabled to add  custom adapter modules, can we add custome adapter module on xi receiver channel to generate dynamic queue id ?
    Really appreciate your immediate help and suggestions.
    Thanks.
    Suraj.

    Dear Praveen,
    Thanks lot for the immediate reply, we need to use EOIO, as the messages need to be processed in the same order we send and receive, there is no flexibility in QOS=EOIO, Appreciate if there is any other thoughts?
    Thanks In Advance.
    Suraj.

  • How can a JMS adapter be configured in BPEL to consume messages from multiple queues ?

    How can a JMS adapter be configured in BPEL to consume messages from multiple queues ?

    If you want to use JMS with AQ as datastore then there is some configuration you need to do to enable this. This is outside SOA Suite per sa, e.g. no adapter required.
    If you want to connect to the AQ direct then use the AQ adapter.
    this blog may be of some help understand the configuration

  • Urgent : MDB stops listening to the queues after some time  !!!

    Hi,
    I am using OJMS with OC4J 10.1.2 and db 9.2.0.5. I have a web application which send messages into the queue very frequently.
    But the problem is the MDBs stop listening to the queues after some time (1-2 days) and no more messages will be dequeued from that point.
    All these messages will move to the exception queue after their expiry.
    But the dequeing agains resumes after restarting the OC4J !.
    I guess, at some point mdbs are either becoming busy (locked ) or some exception occured while dequeing, hence they stop listening to the queues.
    Please throw some light on this issue as it is very crucial in my project.
    Regards
    Prashanth

    I've noticed this lately as well, with my iPhone 4. I couldn't confidently pin it directly on any particular iOS update, but my iPhone used to automatically connect up via Bluetooth with my Prius's handsfree feature, and now it doesn't. I work with a CE-based device at my job, with Bluetooth capability, and I used to test out that feature by having it discover my iPhone. This no longer works either.
    What I have found (not really a solution, but it does work and may be a clue for Apple) is that if I simply go to the Settings app then the General -> Bluetooth screen and let it sit there, it will pair right up with my car within a few seconds. Bluetooth is always on, and always says "Now Discoverable" at the bottom of the settings screen.

  • Multiple Queues in BPM

    Hey,
        In case of multiple queues in BPM.
        say for instance multiple queues(random)      
        When we check in SXI_MONITOR, in the QueueID column we get :
              XBPE_TaskId_No_QueueId.
    Please can you tell me what is the significance of  "No" in the above QueueId
    normally its 1 or 2.
        can you also tell me how it affects the queue behavior.
    regards,
           Milan

    Prateek that is what i have done.
    two files are picked from the file adapter they are merged and placed back on the ftp.
    Now this scenario was working as expected when the no was 1. (i.e it went into sysfail, when both the files of the same instance entered different queues)
    but in subsequent runs, when no was 2,  it started working as i have explained. (i.e. it worked absolutely fine without getting into sysfail)
    I have not done any changes in the configuration it happened automatically.
    so i am not able to understand the phenomena.

  • Multiple Queues - Dequeueing resources?

    We have multiple queues on our database which have been configured to be automatically processed by registering stored procedures with each of the queues. The processing of messages works fine, however if we have messages in both queues then it appears as though an attempt is made to process all messages in one queue before it processes messages in the other queue. Are there any settings that we can look at setting to distribute the processing equally between queues?

    Other than job_queue_processes, I don't know.
    Have you made any progress with this?

  • Queue Scaling by Multiple Queues

    Currently, it allows to scale by only one queue.
