Can you please share sample code?
Is it possible to define which include WMQ Queue Manager and JMS Queue Manager?
So that QR will receive message from Q1 through cluster definition? |

You don't want sample Java code from me!
There are any number of samples supplied with the product or available on the web that will suit you. Remember you're just reading from one queue and writing to another.

Define where?

I thought you said above:

So no, if there's no connectivity between the two queues of course you can't use the cluster. If you could use the cluster you wouldn't need code as discussed above.

You keep using "JMS Queue" and "JMS Queue Manager" as if they were meaningful in and of themselves.
Either the Weblogic server is acting as a JMS Provider, and the queue QR is hosted by that JMS Provider, or it's actually MQ that is acting as the JMS Provider and hosting all queues.
If it's the first, then there's no way to have an MQ queue manager move a message to a non-MQ queue manager.
If it's the second, then there's no need to move the message, because you're already reading it from the right queue.
JMS provides a set of standards for applications to use, it does not provide any implementation of those standards.
There's no such thing as a generic JMS queue or a generic JMS queue manager. |

You'll have to create or buy a JMSBridge...

Or configure WebLogic to use WMQ as a JMS provider, and then change the JNDI that the application uses to point at the right thing. |

In the 2nd option are you suggesting Weblogic Foreign JMS Server Configuration With MQ Series. Where remote JNDI name will be the queue names which are on the MQ side. Right?
Between JMS Bridge and this Foreign JMS server configuration which option is better? |

If you are looking at using the Message Bridge that is part of the Weblogic product, then you are bridging from an external JMS transport (MQ in this case) to internal queueing inside the Weblogic server. This is what I take you to mean when you are saying "JMS queue".
I would ask what benefit you think you are getting by using the Weblogic JMS queues as an intermediate store when messages are originating on MQ?
If you do consider using the bridge then look carefully at the Quality of Service (QoS) and Batch Size. Both of these can affect performance. In fact, if your requirement is not to lose a message and you select a QoS of "Exactly Once" then you are asking Weblogic to ensure that no messages are lost (something MQ is already providing for you) then I have found the Weblogic queueing can be a bottleneck. I have seen a project that was using the bridge as an intermediate hop and because of performance issues they switched to a purely MQ messaging to remove this bottleneck (QoS of exactly once and batch size of 1!).
You need to assess your own application requirements and make your own decision on which best suits your needs. But one more thing to be aware of is that your MQ Admins will generally have no visibility of Weblogic queues and troubleshooting messaging issues will therefore need 2 different groups of people/skills.
Personally if you don't have a compelling reason to use internal weblogic queues then using MQ as the single message transport (configured as a foreign JMS provider) is simpler and let weblogic take care of the application.
But certainly you need to consider your own requirements, do your own testing and not rely on advice from a forum. 
Good luck. |
