How to configure multiple MDP for concurrent processing.

[sharadyadav]

Hi,

I've used Spring JMS in a recent project and it has worked very well.

We now have another project wherein the WebSphere MQ is the messaging middleware and we've configured upto 5 MQ Message Listeners for every Queue Manager.
In order to achieve maximum throughput, we wanted to configure a pool of 5-10 message driven pojo(s). I cannot seem to find this configuration in Spring's documentation. Should this setting or configuration be done on Spring's MessageListener Adapter? As per the documentation, the MesasgeListenerAdapter is multi-threaded and it'll create an instance of the MDP in every thread. We wanted to configure the exact number of MesasgeListenerThreads that can be alive & operational at any given time. Is such a setting possible?

Please let me know.

Thanks
Sharad

It is all there in the documentation.

With the setConcurrentConsumers you can set the initial size of the pool, with the setMaxConcurrentConsumers you can set the max.
