Events are generated as a result of activity in a database or in an application system. You can use events to trigger an action in your application. For example, an update to a database can reflect an update to customer information. If your application must perform when this happens, your application is a consumer of this event.
After you create a connection to your application system, you can add events using iWay Explorer. To create an event, you must create a port and a channel.
The following is a description of how ports and channels work:
A port associates a particular business object exposed by the adapter with a particular disposition. A disposition defines the protocol and location of the event data. The port defines the end point of the event consumption. For example, you can use the MSMQ protocol to route the result of a Purchase Order update in the J.D. Edwards system to a queue hosted by application server. For more information, see Creating an Event Port.
A channel represents configured connections to particular instances of back-end systems. A channel binds one or more event ports to a particular listener managed by the adapter. For more information, see Creating a Channel.
