That could limit the number of MDB instances in the JMS queue?

Hi all, I have an app that publish messages in a JMS queue. In SD in the MDB, I defined the following:

< wls:ejb - name > VfDataMiner < / wls:ejb - name >
< wls:message - driven-descriptor >
< wls:pool >
< wls:max - beans-in-free-pool > 25 < / wls:max - beans-in-free-pool >
< wls: initial-beans-in-free-pool > 10 < / wls: initial-beans-in-free-pool >
< / wls:pool >
< / wls:message - driven-descriptor >

My understanding is that this should create up to 25 multilateral development banks to process messages when necessary and that number will fall to 10 if there is no traffic. However, it does not appear so as I saw that 16 consumers at all times.

At first, I thought it might be that the server is running out of threads to spawn new BMD so I also added the thread pool using the - Dweblogic.threadpool.MinPoolSize = 100 in the start, but it is always showing 16 consumers. I miss any idea what else do you? I use this on WLS 11 g.

Thanks in advance for the advice/pointers.

http://download.Oracle.com/docs/CD/E12840_01/WLS/docs103/EJB/message_beans.html

The number of MDB instances in the free pool is limited by the value of the element of max-beans-in free-pool in memory of weblogic-ejb - jar.xml and available. The value of max-beans-in free-pool is > determined by the following rules, in order of precedence:

If a custom ExecuteThreadPool is set, the number of threads MDB is identical to the value of ExecuteThreadCount.
If a WorkManager customized with max-son-constraint is defined, then the number of threads MDB is identical to the value of max-son-stress.
If the autotune option is disabled, the number of threads MDB is equal to the:
(ExecuteThreadCount / 2) + 1

The number of threads MDB is equal to 16 (this is the default).

If you want more of 16 sons define a handler for a custom job and associate it with the strategy of sending of the mdb.

  • Dynamic creation of the JMS queues

    Hello

    I understand that it is possible to define queues (and subjects) in configuration appropriate application jms.xml file. However, I suppose it is also possible to dynamically create JMS queues (i.e. at run time).

    Could someone point me in the right direction for more information on how I can achieve this? I used have a Oracle 10 g and intend to use Oracle AS JMS.

  • Copy of the JMS queues

    I write Weblogic Integration (WLI) applications. When I deploy these apps I create JMS queues on the server or I get warning messages in the Weblogic console. I have several Weblogic 10.3 servers that I need to deploy these applications WLI too.

    I wonder if there is a way I can copy the contents of the xml files that define the queues JMS from one server to another server? What are the files should be copied? I'm trying to find an easier way to create JMS queues. Create queues in the console can get a lot of time if you have a lot of queues to create.

    Any help is greatly appreciated!

    John

    Hi John,.

    There are several ways to automate the configuration of WebLogic and WebLogic JMS (like all other subsystems WebLogic), can be configured with any of them. Here are a few:

    -Script WLST on-line or off line

    -Program in Java that makes calls to mbean JMX config

    -If the JMS-dest config is absolutely identical, then you can just copy the XML of the JMS module in different areas and then use the console, JMX or WLST to modify the config.xml file to reference it. The module contain config destination, while the config.xml file contains subdeployment, store, and JMS server config.

    When you work with several WebLogic domains, make sure that all domain names are different and all the WebLogic Server names are different (even if the WebLogic servers are in different domains). In addition, in some cases all the JMS server names must be different (even if they are in different domains - apply to the apps feature FAS that use meet cross-domain if I remember correctly).

  • Message-Driven beans and the order of the messages in the JMS queues.

    Hi all

    We use Weblogic 10.3.6 and we have a cluster with 2 JMS servers. In our project, it is important to process messages in the order when they arrive in the queues.

    Our question is simple enough, the fact that Message-Driven Beans (of the sort that take up messages in parallel) follow the order of the messages? Or do we need to configure something to do this.

    Thank you!

    According to the oracle documentation:

    With the help of unit-of-Order with Destinations spread

    As already mentioned in the Message of treatment according to the specification of JMS, Service of Message in Java specifications (to http://www.oracle.com/technetwork/java/jms/index.html ) doesn't guarantee no message ordered delivery when applications use distributed queues. WebLogic JMS redirects messages with the same disorder unit and have a target distributed to the same distributed destination member. The Member is chosen by unit of the order of the destination configuration:

    You can also

    If you distribute, you can use control unit andmax-beans-in-free-pool:

  • Limit the number of messages on iOS?

    You can limit the synchronization time in settings - Mail, Contacts - which could limit the number of emails

  • Buffer could replace the queue in the design of producer/consumer model

    Hello

    I have a question to which the task of buffer to store the data and the queue is also of the same thing so we could use the inplace queue buffer in a design of producer/consumer model.

    No, these examples of buffer not almost equal to a queue, and never "replaces" queue at the producer/consumer.

    The advantage the most important of the queues for the producers/consumers (which none of the other mechanics buffer sharing), it is that it works activities to warn the reader that the data is available. So if you would simply replace the queue by mechanics of tampon too developed that you have attached to your last post, you will lose a large part of the object using producer/consumer.

    Thus, to compare the two mechanics:

    -Tail works activities, while the example of the buffer is not.

    -Tail must allocate memory during execution if several items are written in that corresponding queue. This also applies to the buffer (must be resized).

    -Given that the buffer is actually simply a table with overhead, memory management becomes slow and messy with the increase in fragmentation of memory. Queues to play much better here (but have their limitations, there also).

    -Overload of the buffer (the table manipulation) must be implemented manually. The queue functions encapsulate all the necessary features that you will need. So the queues have a simple API, while the buffer is not.

    -Given that the buffer is simply a table, you will have a hard time sharing the content in two parallel running loops. You will need to implement an additional charge using data value references to manage the buffer or lose a lot of memory using mechanics as variables. Lose the memory, you will probably encounter racing conditions so don't think not even on this subject.

    This led to four '+' for the queue and only a single point where 'buffer' is equal to the queue.

    Hopefully, this clears things up a bit.

  • Issue, while reading the file data from a JMS queue

    Hello

    I'm trying a simple case to receive the XML of the JMS queue and inside BPEL use Assign activity to read data in a temporary variable to check the file from the JMS queue. I do the archive file name, CHRAPcXMLInvoices_DUNS_XXXXXXX_datestamp.dat, XXXXXX as the mapping of the identity of the XML from the JMS queue. Some reasons is not mapping... Can someone help me on this please? I stuck here because my final requirement was to insert the data from the XML file in a custom table, but because of this, it fails saying "can not insert a null" which means that some how he does not read the data...

    I enclose the screen... Please help...

    Hello

    I would try to replicate the same at my end, but you can do the following to me.

    You could manually put the message ("but add xmlns ="http://www.example.org" in cXML item payloadID") in the JMS and test it.

    For Ex:

    " xmlns ="http://www.example.org">"

    The XML message is clearly the namespace XSD lacks. The BPEL is looking in the correct namespace (xmlns:ns3 ="http://www.example.org" ") of the XML message, but as space of names are not added to the incoming message sound throw an exception.

    So, try to add the namespace to the XML message and publish manually in the JMS queue to start the process.

  • Problem in the JMS Quota

    Hello

    We got a scenario in which we stop accepting messages from the producer if the JMS queue quota is full. (for example. Configured for the queue quota is 10). While publish us messages from JMS queue in OSB when the quota is full, we need to catch the error of the weblogic and had to turn and must send the response to requests citing that the size of the queue is full.


    Citing the queue of proxy of the OSB and the quota is reached, OSB throws no error even we have set up the mechanism in part necessary exceptions Management error Manager. But when we try to introduce messages directly running the business of producer service (configure JMS) when the quota is full his spear an error response: (the call resulted in an error: weblogic.messaging.kernel.QuotaException: Quota blocking the time limit and no quota available.) But when the call to the proxy service is not to throw any error.


    Thanks in advance

    Can try you a Service call for business, instead of post?

    It's just a scam.

    Force restart our iPhone.

    I thought about it, but I'm not a big fan of resource pools.

    It is interesting because ALL things made of ESX, pools are my absolute favorite, you can do a lot with swimming pools.  Even monitor the pools by a group of permissions, restrictions, segregation, performance, ease of management... This list is long...
