You can use event driven message processing to control the flow of messages through your message flows, by using aggregation, message collections, message sequences, and timeout flows.
Information about the state of in-flight messages is held on system queues that are controlled by IBM® MQ, so you must install WebSphere MQ on the same computer as your integration server if you want to use event driven processing. The system queues that hold the state information are owned by the queue manager that is specified on the integration server. You associate a queue manager with the integration server by specifying the queue manager name on the defaultQueueManager property in the server.conf.yaml configuration file; for more information, see Configuring an integration server by using the server.conf.yaml file.
You must create the system queues by running a script command, as described in Creating the default system queues on a WebSphere MQ queue manager.
WebSphere MQ is
not provided as part of the IBM App Connect
Enterprise installation
package, but your license for IBM App Connect
Enterprise entitles
you to install and use WebSphere MQ.

Enterprise, see Installing IBM MQ.
