Date of First Response: 2009-06-23 04:11:53 Help Desk Ticket Reference: https://enterprise.redhat.com/issue-tracker/301752 project_key: SOA AS-IS) When you configure JmsMessageServiceFactoryImpl to jBPM message service in jbpm.cfg.xml, only one JMS queue is used by this class and current implementation of JmsMessageServiceFactoryImpl may be lack of scalability. TO-BE) Provide a supported way against message service to support multiple queues rather than a single queue for gaining more scalability, particularly load-balancing. Note that the current jBPM reference guide says JMS for asynchronous architectures will support multiple queues in future version[1]. [1] http://www.redhat.com/docs/en-US/JBoss_SOA_Platform/4.3.CP01/html-single/JBPM_Reference_Manual/index.html#futuredirections
There is no intention of supporting multiple queues within the JCA inflow work, scalability and load balancing can already be achieved using a single, clustered, queue. If there is a particular issue with a particular JMS provider then we should address that issue rather than supporting this functionality.
