To communicate events between different agents, you must schedule propagation for the outbound agents on your local system. The Business Event System requires propagation to be scheduled to send outbound event messages.

When you send an event message to an agent, the Event Manager places the message on the queue associated with the outbound agent. The message is then asynchronously delivered to the inbound agent by propagation.

You can use Oracle Enterprise Manager to schedule AQ propagation for agents that use the SQLNET protocol. See: Oracle Enterprise Manager Support, Oracle Application Developer's Guide - Advanced Queuing or Oracle Streams Advanced Queuing User's Guide and Reference, and Distributed Management, Oracle Enterprise Manager Administrator's Guide.

If you are using the standalone version of Oracle Workflow, you can also use the Check Setup web page to schedule propagation for your local outbound agents. The Check Setup page lets you verify whether the required propagation is scheduled and schedule AQ propagation for agents that use the SQLNET protocol. See: To Schedule Propagation for a Local Outbound Agent and To Update or Delete a Propagation Schedule.

You can use the Oracle Workflow Manager component to review the propagation schedules for your local outbound agents. Oracle Workflow Manager is available as a component of Oracle Applications Manager if you are using the version of Oracle Workflow embedded in Oracle Applications, or as a component of Oracle Enterprise Manager if you are using the standalone version of Oracle Workflow. For more information, please refer to the Oracle Applications Manager online help or the Oracle Enterprise Manager online help.

If you want to use the standard WF_OUT and WF_JMS_OUT agents or custom agents for event message propagation, ensure that you schedule propagation for those agents. You do not need to schedule propagation for the WF_CONTROL and WF_NOTIFICATION_OUT agents, however, because the middle tier processes that use WF_CONTROL dequeue messages directly from its queue, and notification mailers send messages placed on the WF_NOTIFICATION_OUT queue.

For agents that use protocols other than the SQLNET protocol, you must provide external propagation logic. See: Agents, Oracle Workflow Developer's Guide.
