When the Type attribute is LOCAL (the default for a stand-alone Application Server instances), the Application Server will start and stop the MQ broker specified as the Default JMS host. LOCAL type is most suitable for standalone Application Server instances.
To create a one-to-one relationship between Application Server instances and Message Queue brokers, set the type to LOCAL and give each Application Server instance a different default JMS host. You can do this regardless of whether clusters are defined in the Application Server or MQ.
With LOCAL type, use the Start Arguments attribute to specify MQ broker startup parameters.
