Populating a JMS queue

Dear All
I need to test my JMS scenario. In real time the JMS queue will be populated by an external system.
For testing purpose how can I populate the queue?
Is there anyway other than doing a file to JMS scenario to populate the same.
Thanks
Sourabh

Hi,
There is no other alternate to invoke the queues.
As you said, use File adapter to test the secnario.

Populating Database records to WLS JMS queue

Hi All,
Please suggest which is the performance effective approach in populating WLS JMS queue from the database tables?
As I have to produce millions of records from the DB into the JMS queue and assuming using DB adapter and retreiving bulky data is a long running process.
Please suggest whether I can write a pl/sql stored proc and populate the WLS JMS queue? or is there any other most optimistic approach to transfer data from db into WLS JMS queue?
Thanks,
Sudha

Thanks Eric for the quick reply. Also, going through the other forum:
Re: Publish message from Oracle database PL/SQL to a remote WLS JMS queue
Just want to know which one would be performance effective one in the below whether using Java stored Procedures or populating AQ and WLS Messagin bridge?
1) Java Stored Procedure can use JMS APIs to publish messages to WLS JMS destinations. JMS standard API jar file and WLS JMS client jars that you use need to be loaded into database.
2) From PL/SQL, you can publish message to AQ using AQ PL/SQL APIs, then configure WLS Messaging Bridge to forward messages from AQ to WLS JMS.

Issue in Synchronous OSB using Jms Queues in OSB11g

Hi,
I am working on building a synchronous OSB using the following steps.
1)     Creating the Synchronous OSB Proxy Service which routes the message to the business service which in turn places a message in the Queue(inqueue) by populating the JMSCorrelationId and waits for the response message to consume from another queue.
2)     A Composite(SOA) will consume the message from this Queue
3)     It will do necessary transformation and Places it in another Queue (Say Response Queue).
4)     OSB Business service waiting in Step 1 will receive the response from this response Queue.
I used a sample Wsdl which has both request and response message types.
I observed that the correlation ID is maintained properly from inqueue to response queue. But the message is not getting picked up by OSB from the response Queue
Twist: It is working absolutely fine in OSB 10g but it is not working in OSB 11g.
I tried using Messaging service as well as using the sample WSDL i.e keepiing the soap message in the queue. Both the cases are working absolutely fine OSB 10g but not in OSB 11g.
Can anyone faced a similar issue or any pointers will be great help in this regard.
Regards,
Ashok

To debug this further can you check if the response Q has any active consumers. ? When you use response by correlation ID business service, OSB actually creates MDB's with message selectors under the hood.
This is a sample of the ejb-jar.xml of the MDB created for a business service with response by Correlation ID pattern.
<?xml version='1.0' encoding='UTF-8'?>
<jav:ejb-jar xmlns:jav="http://java.sun.com/xml/ns/javaee">
<jav:display-name>BEA ALSB JMS Outbound Sync-Async Endpoint</jav:display-name>

<jav:ejb-name>ResponseEJB-6577847719916437493-3893eeb7.1287d30ba4f.-7fe1</jav:ejb-name>

<jav:transaction-type>Container</jav:transaction-type>
<jav:message-destination-type>javax.jms.Queue</jav:message-destination-type>
<jav:activation-config>
*<jav:activation-config-property>*
*<jav:activation-config-property-name>messageSelector</jav:activation-config-property-name>*
*<jav:activation-config-property-value>JMSCorrelationID LIKE 'ID:424541534594cf52%'</jav:activation-config-property-value>*
*</jav:activation-config-property>*
</jav:activation-config>
<jav:env-entry>
<jav:env-entry-name>service-ref</jav:env-entry-name>
<jav:env-entry-type>java.lang.String</jav:env-entry-type>
<jav:env-entry-value>BusinessService$Test$RequestQ</jav:env-entry-value>
</jav:env-entry>
As you can see the message selector is based on JMSCorrelationID LIKE 'ID:424541534594cf52%'. This means the business service will pick only those messages which has its correlation ID starting with ID:424541534594cf52.
You can see the message selector for your MDB from admin console --> deployments.
Check and confirm if the correlation ID created in the request also starts with this value and the same is send back from the server. Also try deleting and recreating the business service or rename the business service which will create a new MDB under the hood and check the above.

Advantages and Disadvantages of JMS Queue over Fabric

HI,
I want to know both the advantages and disadvantages of using JMS queue over the default Fabric queue in B2B adapter.
Is it ok if I configure all my inbound and outbound transactions across all the trading partners to communicate with their respective SOA composite via the default JMS Queues(B2B_IN_QUEUE and B2B_OUT_QUEUE)?
Please advise.
Thanks in advance.
Regards,
Monica

Hi Monica,
But the size of the payload which I am using is unpredictable, it can differ from 1 MB to 40MB in future.This is not a problem. B2B can handle MB's of file if server has enough resources.
all other payloads greater than 3MB, it is getting faulted with the message:
"SAX Exception in translator. SAX Exception raised while trying to SAX Parse InputStream . Please make sure that the xml data is valid."Please remember that when B2B will find a large payload then it will write the large payload into the "Large Payload Directory" (defined in Administration--> Configuration) and pass it's reference to the middleware. So at middleware, you will not receive the actual payload but you will receive it's reference. Using File adapter sync read option, you may read the large file from "Large Payload Directory" at SOA layer.
If you are using PS5 (11.1.1.6) then you will see that for large payload, B2B passes the JMS header LARGE_PAYLOAD to the back-end so in your composite, you may build logic around this. If this header (LARGE_PAYLOAD) is not coming at SOA layer then payload will be available in the body and if it is populated then payload will be available in the "Large Payload Directory" and it's reference will be available in the message body.

How to read the messages in the JMS Queue using JMX

Hi,
          I want to read messages in the JMS queue using JMX. I was able to read using QueueBrowser but want to modify priority of the messages using JMX.
          I tried to use JMSDestinationRuntimeMBean but it does not allow us to read messages unless we pass the message Id. Is there any way that I can get all the messages in the queue.
          I am using Weblogic 8.1 SP4
          Can someone please help me in this regard.
          Thanks,
          Kiran.

Hi,
As far as i know, JMS Object Messages is not supported by XI JMS adapter.
you need to have the JMS provider to transform the message to bytes messages.
(Refer to SAP note 856346)

How to configure my JMS QUEUE serve only one message at a time?

Hi All,
I have requirement where I need to develope a JMS QUEUE in weblogic. This MDB has to serve only one message at a time. Is there any way to configure via annotations or in weblogic server settings ?
Any help would be really appreciated...
Thank you,
K.

I'm not aware of any way to configure the max pool size via annotations, you might try posting to the EJB newsgroup (please post back the answer). Of course you can set the size via an EJB descriptor, as per the MDB chapter of the Performance and Tuning guide in the edocs.
By the way, if you have ordered message processing requirements, I highly recommend taking a look at the WebLogic JMS "Unit-of-Order" (UOO) feature as per the UOO chapter of the JMS programmer's guide. For a variety of reasons, the UOO features is often, by far, the best option for handling such requirements. If this feature applies to your use case, then there would be no need to force single threaded message processing in some sort of manual fashion (the feature enforces this for you).

Dequeue from JMS Queue 10 at a time and process it.

Hi,
I have created a JMS queue in weblogic.
Say i enqueue 1000 records in the queue at one go.
Now, i want a bpel process to dequue from it and process it.
However as per my requirement i want at a time 10 instances being active at a time i.e. 10 records from the queue are being processed at a time.
Once any one of them finishes, the other will pick up the message.
1 BPEL instance will process only 1 record from Q at a time
Please let me know how to achieve this.

You need to understand here that it is adapter which deques the message from queue and it will deliver it to BPEL for processing which is an async process. So adapter will keep dequeing messages and keep publishing it to BPEL irrespective of whether BPEL process has completed processing.
You may need to tweak the adapter configuration here. First of all create the synchronous BPEL composite so that both adapter and BPEL work in same transaction -
https://blogs.oracle.com/adapters/entry/creating_a_synchronous_bpel_composite_using_file_adapter
You may control the number of threads for inbound JMS adapter using binding property "adapter.jms.receive.threads" in composite.xml

Multiple Messages in Same JMS queue

Hello,
I have interfaces in which different xml messages from the same sender system will be placed in the same MQ queue, is there a way that XI JMS sender channel can differentiate the xml messages based on the payload?
I can create a single communication channel, but the outbound message interface I cannot create a common structure because the xml messages are huge and there will be future interfaces following the same architecture.
1. How can I route in interface determination based on the context in the inbound msg interface?
2. What can I provide as Message interface for the outbound?
3. MessageSelector attribute in Adapter specific properties - any ideas on this? - I can select this in the condition context in interface determination - can I give any values here to differentiate msges?
4. Value mapping - is it possible to define the sender message interface through this?
Any idea is appreciated..THank you..

Hi Thanujja,
We have recently completed a project that had this requirement too. We made use of the MessageSelector to solve this problem. You'll need to make use of some advanced (advanced tab)settings in the comm channel. Basically you want to add Additional JMS Message Properties. You can add up to 10 additonal JMS Properties.
Let's say you've added a property called MESTYP. You then need to get the sender to populate the MESTYP property with a text value for each IDoc involved e.g. DELVRY. You would then set your JMS Message Selector field as follows: MESTYP='DELVRY'.
You'll have a comm channel for each IDoc. These comm channels will then connect to the JMS Queue & only pick up messages that meet the criteria at set in the Message Selector.
There was one other problem that encountered with Message Selector, we were on XI version 7.0, the Message Selector was working intermittently & then we applied SAP Note 1256636 & upgraded to 7.01. Everything is working fine after that.

Reading Message from Foreign JMS Queue in SOA Suite 11g.

Hi,
I am trying to read a JMS message that has been put into a JMS Queue on a remote weblogic Server.
The steps that I know is that I need to create a foreign JMS Server and then probably use JMS Adapter to subscribe to the message that is lying in the remote queue.
Has anybody been able to achieve this kind of scenario working for a remote JMS queue? Also, is this supported by JMS Adapter in SOA11g?
Any help will be appreciated.
Regards,
Varun Maheshwari

Hi Atheek1,
Thanks for your reply.
The confusion that is pondering me is that do I need to create a Foreign JMS Server or should I create a JMS adapter and override the properties.
I have tried the steps for creating a Foreign Server from the below link
Unable to access remote JMS Queue through JMS Adapter
But I am not able to find the Foreign Server created and any connection factories and Destinations related to foreign Server in my JMS Destination while configuring JMS Adapter.
I am not sure how to do step2 as entailed by you.
Could you please explain me in little detail on how to do this or redirect me to some blog or forum which will be really helpful.
Cheers,
Varun

What have you configured for the response tab for the sender? Are you using the MPL or the MDB?

Need to publish message from database to a JMS Queue using Java

I need to publish messages to a Websphere JMS Queue whenever any changes happen on a particular column of a table in oracle 11g. For that I have written a trigger on that particular table which in turn will invoke one java procedure. I have written the java procedure using a standalone java class and uploaded the java class as a schema object. While executing the procedure it is throwing error as it is not able to instantiate some of the java classes. I don't know how to provide the reference of different jar files while executing the java class. Can anyone help me on this.

Welcome to the forum!

>
Clarify your statement. First you say 'standalone java class' but then you talk about instantiating java 'classes' and referencing 'different jar files'. If you are executing your Java class inside Oracle then any Java classes that your java class is referencing also have to be loaded into Oracle or it won't be able to reference or execute them.
How do you plan to ' publish messages to a Websphere JMS Queue '? Where is this queue you are talking about?
Why are you using a Java procedure and class instead of PL/SQL?
What is your 4 digit Oracle version (result of SELECT * FROM V$VERSION)?
