I have a WebLogic cluster up and running an application containing an MDB. I'm currently using WebLogic JMS queues to send messages to the MDB. All is well.
I now have need to switch to IBM WebSphere MQ for my JMS messaging.
I can set this up and send/receive messages in a non-clustered environment (Admin server) using a Foreign server with a bindings file. However, I can't seem to properly configure the clustered environment for MQ integration to work correctly.
I get the following when deploying the EAR/MDB on the cluster:
The Message-Driven EJB: xxxMDB is unable to connect to the JMS destination...
javax.naming.NameNotFoundException: Unable to resolve 'jms.xxxQueue'
Can anyone point me to some documentation on how to configure IBM WebSphere MQ in a WebLogic cluster?
Thanks!
there is a need to add several MQ JMS classes to the PATH of the weblogic so it will be able to connect to MQ
the path needed to be added is : *MQ_system_path*/java/lib64
beside that here are the clasess i have found that are needed to make this thing :
com.ibm.mq.mqi.jar; com.ibm.mq.headers.jar; com.ibm.mq.jar; commonservices.jar; com.ibm.mq.jms.jar;jta.jar;
this what helped us to connect weblogic to MQ

I am just starting out to use Anypoint MQ and in the past have used Apache ActiveMQ.
In case of Apache ActiveMQ , Mule connector provides an option where we can choose if we want to publish a message as Persistent Vs NonPersistent
Dont see that option with Publish connector for AnypointMQ
Tried googling but am not getting any details regarding the same ....
any pointers would be appreciated .. Thanks !
Anypoint MQ doesn't used that terminology or has an equivalent feature. Having said that it always operates in a similar way to ActiveMQ persistent mode. You can find it in the public documentation:
Because the storage solution for Anypoint MQ is durable, messages that were already in the Anypoint MQ system before service was interrupted are retained.
Does weblogic expose metrics through Jmx so it can be monitor with prometheus ?
What is the best solution to monitor weblogic servers (threads, datasources...) ?
The answer is yes. WebLogic Server expose all its configuration and runtime metrics through a JMX interface. See this documentation for details.
The Oracle WebLogic Server blogs publishes several articles about weblogic and prometheus. This article explains how use Prometheus and Grafana with WebLogic server for instance.
I am new to Mule and followed this blog to create a "websphere-mq connector" through the jms connector. I am using the community edition.
In order to connect to the websphere mq server, I must run the application under a specific Windows username. Running the mule application in Mule Design under the specific username, I am able to connect and receive messages. However, I am unable to connect to the websphere mq server through the standalone application running on a windows server. I changed the user on the service that is running mule to the specific user but am unable to get authorization to the websphere mq server.
Any additional insight would be much appreciated.
I would suggest reviewing the "Getting going without turning off security" article for an introduction to MQ security. This might help get the MQ system correctly configured.
The stand alone application runs the Tanuki Software wrapper as the user assigned to the environment variable %USERNAME% in windows. Even though I updated the user in the Mule service to run as the approved user, the wrapper will take the environment variable.
To solve the problem, I updated the wrapper.conf file to include the following:
set.USERNAME=<approvedUsername>
the environment variable %USERNAME% is now set to the approved username, in which mule will allow the JMS connector to the authenticate with the correct username.
I am working on developing an interface between TomEE application server and rabbitmq.
Is there any example that can show me what is to be configured in the tomEE server ?
How can I initiate tomEE to create a exchange and queue and than send out messages ?
not sure I fully got the question bu you can embed java client in your application and use Java API: http://www.rabbitmq.com/tutorials/tutorial-one-java.html
If you want to use JMS you can rely on https://github.com/imatix/openamq-jms but since there is no rabbitmq resource adapter it is still "manual".
I'm can't find instruction for integration websphere mq 6 + weblogic 12 c by websphere native protocol (no jms!). It possible? Goal - deploy mdb in weblogic for getting message from websphere mq queue.
and response.
Please help with link or instruction.

I understand that the option of using WebLogic's Foreign JMS provider configuration is not available to you as you want to NOT use the JMS API, but MQ's specific API, correct?
If that is the case you could always try to write some MQ Client code using the MQ API, as you would for a stand-alone application, and then deploy it inside WebLogic, although I'm not sure whether that would give you any real benefit.
One thing I am pretty sure you will NOT be able to do is write a Message-Driven Bean which connects to an MQ Series queue using the MQ API. MDBs are a Java EE concept and they are meant to connect to JMS providers.
