As per http://jmeter.apache.org/usermanual/component_reference.html#JMS_Point-to-Point
the communication style clear is used to clear the messages from the given queue.
Scenario: In my test plan , i have 2 threadgroups.
1) JMS Point to Point sampler to send messages: My JMS sampler fires request_only messages to the inqueue.
2) JMS Point to Point sampler to clear the messages in the outqueue. Here the communication style is selected as "clear" and the outqueue has been specified in the "JNDI Request queue" field.
On running the test plan almost always the View results tree shows that the clear JMS sampler has cleared 0 messages from the outqueue.
Any idea why this is so.
My objective is to ensure that the outqueue is drained regularly. Please advise if there is a better way to do this.
JMeter 4.0 supports clear option in JMS
JMS Point-to-Point sampler has been enhanced with read, browse, clear options.
So you can choose communication style clear

I want to perform load test on a Tibco JMS endpoint using JMeter. The endpoint is a JMS Queue Receiver that will reply to the JMS Message to end the sessions. I have done a lot of googling regarding what parameters to fill in each field of the JMS Point-to-Point sampler with no success. Attached is a screen shot of the Jmeter window. I am not sure whether this is the right sampler to use or if I should use Publisher. Either way, I do not know what to fill in each of these fields. I am currently stuck at the JNDI name Request queue field. When I put my queue name for the JMS on Tibco, I get an error that that name is not found. Leaving the field blank is also problematic. What should I fill in this field to make the request work?
We don't know your topic/queue names so we cannot help, you can ask around, see the application you're trying to simulate configuration or use Graphical Administration Tool for TIBCO® EMS to explore the endpoint and identify the proper queues for messages sending/receiving. For sending the messages you might need to set JMS_TIBCO_SENDER JNDI property

We have a requirement in where we need to send only one message at a time to a backend process. The call back of this process takes around an hour, only after the call back can we send another request to the process.
I am trying to achieve this by using a manager bpel process that will hold the messages first if there is already something being processed in the backend, and then send it once it realizes that the backend is free. This approach will work, but our architect wants a cleaner solution. He suggested using JMS queues. The idea is for the jms queue to messages to be read by a amanger one at a time, only moving on to the next one once we receive the callback from the backend and we know that the composite and bpel instance is finished. I've been scouring the internet for weeks, but I couldn't find a working jms based solution for my requirement.
I've tried the suggestions for this link but turning on unit of order and acknowledgement properties does nothing.
Try this approach!!
Use a event driven bpel process.
Use a database flag as your next trigger. (flag is TRUE)
jms Adapter receives first message from the queue. Here use a delay in the adapter since you are expecting the bpel to be long running. use below setting.
<binding.jca config="MyServiceInboundQueue_jms.jca">
<property name="minimumDelayBetweenMessages">10000</property>
<property name="singleton">true</property>
</binding.jca>
if flag == TRUE in the db causes the db adapter to proceed with the bpel process,
else skip the bpel.
mark flag==FALSE
call the backend system
callback is received after an hour.
set flag==TRUE
Hi Jonar,
At my company we always use JMS queues for Asynchronous messaging. You could do with a delay timer build in your composite set to 1 hour and 15 minutes for example, and it will work most of the time, but its hella messy. The whole idea is for any asynchronous process to kick off when a message is put upon its queue target (specified by the JMS queue). The JMS adapter in the composite of your project will pick up the message from the queue when it is free to process the queue. The goal for you would be to put the message on the queue and pick it up from it using the adapter. It will know which message to pick up because you specify which queues it listens to in the adapter.
The following blog post by John-Brown Evans eplains the whole process from step one. It might be a bit tedious, but I found it very helpful. Its using SOa Suite 11g instead of the nowadays more commonly used 12c, but its fundamentals remain the same.
Awesome JMS queue tutorial
I hope this works for you!

For my master thesis I built a pub/sub with ActiveMQ and now need to evaluate the broker's performance with Jmeter. To do so, I need to simulate the use case I implemented. It contains multiple publishers and subscribers sending messages to several topics. By now, I do not see a possibility to define that in the JMS Sampler. I tried to simply separate the topics by "," but it does not function.
dynamicTopics/MyStaticTopic1, dynamicTopics/MyStaticTopic2
I read all information about JMS Test Plans, but none is discussion this aspect.
Is there a way to do it?
Best regards.
I'm an IBM MQ novice, however have used other messaging systems in the past (Solace, RabbitMQ, BizTalk). I apologize if some of my MQ terminology is incorrect when it comes to local/remote/transmission queues etc.
I am integrating with a 3rd Party using MQ. I have no control over the use of MQ when it comes to this 3rd party. They define the set integration pattern.
I have my own local Queue Manager.
The 3rd party supports many 100s of different message types.
Typically each message sent to them will result in a response
Responses on overage will be delivered back to my QM within 0.5s (agreed SLA)
The basic model is as follows;
For all outbound messaging I publish to a single queue
All responses come to a single inbound queue on my QM
I do not believe they respect/use the ReplyToQ or ReplyToQmgr header properties
High level overview of the use case;
The MQ usage will be very active. Perhaps 500-1000 outbound messages per second
For the vast majority of these - there will be a user waiting for a response
The current design approach is to put a message onto the outbound queue and then create a subscription to the inbound queue with a JMS selector using the correlation ID.
Here is my challenge;
I am not sure if having so many concurrently subscriptions all with a unique filter on the single inbound queue will perform well. I would appreciate insights into this. I have a 2 node cluster running in a docker container. I don't have details on the spec yet.
My preference would be have messages arrive into the inbound queue and then be routed to many "function" specific local queues on the QM.
I would still use JMS selectors on the message ID in this model - however I would hope the load would be spread from a single deep queue to many shorter queues
It does not seem that I could route messages natively within MQ without an addon such as MQ Integration Broker or ESB (some other products within the WebSphere suite).
It is on this last point I could use some guidance. Can I route within my QM? If so - what options do I have. Alternatively - perhaps there are much better approaches that I have not considered?
Any guidance would be heartily appreciated!!
in order to reach high performance production of messages with jms with transactions enabled, one needs to control the amount of messages being sent on each transaction, the larger the number the higher the performance are,
is it possible to control transactions in such a way using spring integration ?
one might suggest using an aggregator, but that defeats the purpose because i dont want to have one message containing X smaller messages on the queue, but actually X messages on my queue..
Thanks !
I'm not aware of your setup, but I'd bump up the concurrent consumers on the source than try to tweak the outbound adapter. What kind of data source is pumping in this volume of data ? From my experience, usually the producer lags behind the publisher - unless both are JMS / messaging resources - like in the case of a bridge. In which case you will mostly see a significant improvement by bumping up the concurrent consumers, because you are dedicating n threads to receive messages and process them in parallel, and each thread will be running in its own "transaction environment".
It's also worthwhile to note that JMS does not specify a transport mechanism, and its unto the broker to choose the transport. If you are using activemq you can try experimenting with open wire vs amqp and see if you get the desired throughput.
