Configure the JMS connection factory for the application, in order to tune the process through which messaging engine connections are selected for the application. To use JMS destinations of the default messaging provider, a client application connects to a messaging engine on the service integration bus to which the destinations are assigned. For example, a JMS queue is assigned to a queue destination on a service integration bus.

By default, the environment automatically connects applications to an available messaging engine on the bus. However you can specify extra configuration details to influence the connection process; for example to identify special bootstrap servers, or to limit connection to a subgroup of available messaging engines, or to improve availability or performance, or to ensure sequential processing of messages received.

For the default configuration, you only have to specify the one required connection property, Bus name, which sets the name of the bus to which the application is to connect. To further restrict the range of messaging engines to which the applications can connect, you can also configure the other connection properties:

The steps for this task are based on an application that uses a unified JMS connection factory. Use the same task to configure a JMS queue connection factory or JMS topic connection factory, but you select the appropriate type of connection factory instead of JMS connection factory.
