Hi
I have MDB in a cluster environment listening to MQ. I am confused about a few things about its operation.
If i have a pool of 10 MDBs and there are 10 messages inside the MQ. Would the appserver retrieve all the messages, assign to each MDB OR the messages will be Processed sequentially as first come first served?

How will the above scenario map to clusters. Will multiple messages me processed simultaneously among the clusters : Load Balancing?

Are there any known issues with MDBs processing the messages in clusters. Each node will have its own listener? Will in that case only one node be picking up messages while other only work incase of failover?

Thanks alot for reading through and appreciate your help and ideas.

GUL

MQ

Do you mean MQSeries or a Mesage Queue?

All your questions are vendor-implementation specific - I'd read your app server documentation, because there's no answer anyone can give which will suit all cases.
