Following is the code that I've written in java.The modelQname is created and existing
as a model queue.I expect the dynamic queue
to be created by the following command.
String modelQName = "ind7_model1";
String dynamQName = "ind7_dynam1";
MQQueue queue = _queueManager.accessQueue(modelQName, openOptions,
null, // default q manager
dynamQName, // no dynamic q name
null ); // no alternate user id
can i access the dynamic queue using the accessqueue method and put messages in it?
What is the use of the dynamic queue?
How do I ensure that it is created?

Your code looks correct me. Once you've created the MQQueue object via the accessQueue, you can use any of the methods that are available to you (ie, put and get).
If the accessQueue fails, then your queue didn't get created.
The most common use of dynamic queues that I've seen is for client programs that will be communicating with a server. They need a queue while they are running and can get rid of it when they are done. Dynamic queues are perfect for this. |

what could be the possible reason?
when i try to access the dynamic queue again
with the access queue method i get a runtime
error of 2085 which implies unknown_obj_name.

I think you're getting 2085 on the second access because this is a temporary dynamic queue. This means you create it by accessing a model queue, and it gets deleted once it there are no more applications holding it open.
If you want this queue to persist then change the model queue to make the temporary queues permanent dynamic (PERMDYN). These queues will persist after creation even if there are no applications holding open handles to them.
Hope this helps,

but i'm trying to use the dynamic queue in tha same application.i guess a permanent dynamic queue is one which survives a qm crash and a temporary is one which doesn't.
so whether the queue is temp or permanent
i shoukd be allowed to use it in the same application.
