      We noticed our MDB is performing too slow and not using the maxSession property.

       

      Infrastructure:

      JBoss 7.2 EAP

      Active MQ 5.15.9

      Active MQ Resource Adapter - 5.15.9

       

      Single Machine Running Active MQ and JBoss.

       

      JBoss is configured to connect to external(on same machine) Active MQ. Configuration is as under.

      JBoss Resource Adapter configuration

      Now, I have a single MDB which reads a message form the queue. I put 100,000 messages on the queue and then deploy my MDB, but in logs I see only 10 threads consuming messages concurrently, however I would assume it should be 15(same as maxSession).

      Can someone help me in this? Where is this going wrong or which property I need to set more to increase the concurrency of this MDB?

       

      Thanks in advance.

          This is not a problem anymore. A silly mistake. Its "maxSessions" and not "maxSession".

           

          After changing the property and increasing the maxSession to 30, we see the following output.

           

          [standalone@localhost:9990 /] /deployment=mdb.performance.ear-0.0.1.ear/subdeployment=mdb.performance-0.0.1.jar/subsystem=ejb3/message-driven-bean=SampleMDB:read-resource(include-runtime=true)

          {

              "outcome" => "success",

              "result" => {

                  "component-class-name" => "SampleMDB",

                  "declared-roles" => [],

                  "delivery-active" => true,

                  "execution-time" => 0L,

                  "invocations" => 0L,

                  "methods" => {},
