Too many Subscribers/Receivers for Queue

Question

The link of Feedback in Java EE 5 tutorial doesn't work, because of this I ask my question here.
I have tried the " Simple Example of Synchronous Message Receives" in Chapter 32 of Java EE 5 tutorial.
In case of destination type queue I got error message.
The log of test:
M:\java\javaeetutorial5\examples\jms\simple\producer\dist>appclient -client producer.jar queue 3
Destination type is queue
Sending message: This is message 1
Sending message: This is message 2
Sending message: This is message 3
M:\java\javaeetutorial5\examples\jms\simple\producer\dist>cd ../../synchconsumer/dist
M:\java\javaeetutorial5\examples\jms\simple\synchconsumer\dist>appclient -client synchconsumer.jar queue
Destination type is queue
Exception occurred: com.sun.messaging.jms.ResourceAllocationException: [C4073]:
A JMS destination limit was reached. Too many Subscribers/Receivers for Queue :
PhysicalQueue user=guest, broker=pc2900:7676(1442)
My question: How can I configure the Queue for more subcribers/receivers?

Answer 1

Hi,
Depending on the version of JMS, this may be a limitation of iMQ PE Edition (This is early in the morning for me, I can't remember which one). So you can look at the documentation, this may be a limitation of PE versus SE or EE. If you can modify it it would be using either the command line imqcmd or the gui based, imqadmin. With it, you can get into the connection factory, and change the maximum number of active consumers onto the queue.
I beleive that using glassfish (as 9) would alleviate this limitation, if it is there, since this is using openmq (imq v4.0).
