How to restrict MQ shall have only one consumer

Hello,

In my modules interaction scinario we defined only one consumer will exist
per MQ, So How to prevent/query that consumer already exists for given MQ.
So That I can prevent Creating consumers for MQ using NMS(C# .net client).

Thanks in advance

Thanks for quick responce
It sound's to me that user can create multiple(exclosive) consumers, but
first created consumer only will get messages right?
Is there any way to prevent to create consumer and log the user saying
"warning:trying to have multiple consumer"
Because in the above method user will see problem only by knowing that 2nd
consumer not getting messages.

Using Exclusive Consumers ensures that only one consumer is active on
any queue at any point in time.

Hi Raju,

the best approach is to develop your own plugin that will do that. Check out

for more info.
