Hi,
I am using MQJMS API to connect to MQ server.
MQ version : 8.0 and all are under XA Transactions
In same, I am pooling XAJMSContext (com.ibm.msg.client.jms.JmsXAContext)
created from MQ XA Connection Factory for operations and all working fine.
However, have one blocker issue regarding Temporary queues
As per requirement, client can provide/change Temporary Model queue at any time.
Now, I am pooling XAJMSContext and couldn't find any method to add/change temporary model queue name.
However, as per IBM docs
Understood that MQXA ConnectionFactory do have setTemporaryModel() method to add MQ Model queue. but that is in the CF object
and I am pooling XAJMSConetext.
Please let me know how can i use different Model queues from Context
object as creating CF every time with new model queue is very expensive task.
Also, it is like that, we can create use only 1 temporary Model queue per CF?
Any help will be appreciated , it is very urgent.
Thanks

So have you looked at all the properties of the XAJMSContext? None that fit the temporaryModel ??

Explain why you need different models

It depends on client, they might create one modelQ for Persistent message and other for Non persistent.
Client ask for option to put Model queue of his choice at run time.
Please help!! |

So if you know the model name (at runtime) create a queue from the model name and see if that matches your expectations...

How does the client intend to put persistent messages on a temporary queue?

As suggested, i create Queue using "modelQueue" Name,MQQueue MQueue mqQueue = (MQQueue)context1.createQueue("modelQueue");
It created MQQueue for me but when try to access it to get messages got below error:
com.ibm.msg.client.jms.DetailedInvalidDestinationRuntimeException: JMSWMQ2022: Cannot create a Message Producer or Message Consumer with a Model Queue 'modelQueue', as a Destination.
The Message Producer or Message Consumer was unable to open the Destination as it was a Model Queue.
Change the Message Producer or Message Consumer to use a different Destination Queue name other than a Model Queue.
at com.ibm.msg.client.jms.DetailedInvalidDestinationException.getUnchecked(DetailedInvalidDestinationException.java:273)
at com.ibm.msg.client.jms.internal.JmsErrorUtils.convertJMSException(JmsErrorUtils.java:151)
at com.ibm.msg.client.jms.internal.JmsContextImpl.createConsumer(JmsContextImpl.java:383)
Please suggest how to create Temporary queue with runtime model Queue |

Well you may well have to create 2 contexts. One for persistent replies and one for non persistent ones. Each context built off a different CF.
Have fun

OK. So, need to create separate contexts for each different model queue? |

May be and may be not.
Say you specify your model for persistent. This means that you need to close and delete the temporary queue explicitly. So as long as your app correctly handles the clean up, one (persistent) model should be enough. Be aware that you may encounter a performance penalty compared to non persistent dynamic queues.
Have fun
