## Scheduling Listeners for Local Inbound Agents

Use the Check Setup web page to schedule listeners for the inbound agents on your local system. The Business Event System requires listeners to be scheduled to receive inbound event messages.

When you schedule a listener for an agent, it starts monitoring the agent's queue on the run day you specify, dequeuing any inbound event messages. When an event message is received, the Event Manager searches for and executes any active subscriptions by the local system to that event with a source type of External, and also any active subscriptions by the local system to the Any event with a source type of External.

The listener exits after all event messages on the agent's queue have been dequeued. Oracle Workflow reruns the listener indefinitely, at the interval you specify.

After you schedule a listener, you can modify its schedule by updating its settings. You can also stop a listener altogether by deleting it.

You must schedule a listener for the standard WF_ERROR agent to enable error handling for the Business Event System. Also, if you want to use the standard WF_IN agent for event message propagation, schedule a listener for that agent as well.
