MDB concurrency (Multiple instances)

[rajasekharreddym1]

My MDB (Message Driven Bean) on message-inflow-driven-bean for IBM MQ using MQ resource adapter on JBoss.

MDB is working fine, but its allowing by default multiple instances of MDB (concurrent MDBs).

As per my project requirement, suppose to use only one instance of MDB.

Plz suggest me how and where i can configure the attributes related to MDB concurrency?

or

a example with concurrency settings would be great!

Thanks

If you are using WSMQ then the number of "sessions" concurrently delivering messages
will be in their configuratoin somewhere. Ask them.
