Event Manager for Oracle Applications

Note: The Oracle Workflow web pages are being converted to the Oracle Applications Framework user interface format. Depending on your version of Oracle Workflow and which patches you have applied, you may see Oracle Workflow web pages in the new format as well as in the previous format. The new Event Manager pages are currently available for the version of Oracle Workflow embedded in Oracle Applications.

The Oracle Workflow Event Manager lets you register interesting business events that may occur in your applications, the systems among which events will be communicated, named communication agents within those systems, and subscriptions indicating that an event is significant to a particular system. The Event Manager also performs subscribtion processing when events occur.

You must have workflow administrator privileges to maintain Business Event System objects in the Event Manager pages. If you have workflow administrator privileges, you can create, update, and delete events, subscriptions, systems, and agents. You can also test business events by manually raising a test event. If you do not have administrator privileges, you can view Business Event System objects in the Event Manager, but you cannot modify them. Workflow administrator privileges are assigned in the Global Workflow Preferences page. See: To Set Global User Preferences, Oracle Workflow Administrator's Guide.

You can use the Workflow XML Loader to upload and download XML definitions for Business Event System objects between a database and a flat file. See: Using the Workflow XML Loader, Oracle Workflow Administrator's Guide.

When an event occurs in an application on your local system, an event key must be assigned to uniquely identify that particular instance of the event. Then the event must be raised to the Event Manager.

You can raise an event by any of the following methods:

Additionally, the Event Manager can receive events sent from the local system or remote systems.

When an event is raised by a local application or received from a local or external system, the Event Manager executes any subscriptions to that event. Depending on the action defined in the subscription, the Event Manager may call custom code, send the event information to a workflow process, or send the event information to an agent.

To communicate event messages between systems, you must schedule propagation for outbound messages and agent listeners for inbound messages. You can use Oracle Enterprise Manager to schedule propagation and the Workflow Manager component of Oracle Applications Manager to run agent listeners. You can also view the distribution of event messages on different agents in Workflow Manager, as well as reviewing queue details for those agents. For more information, please refer to the Oracle Applications Manager online help, Oracle Enterprise Manager Support, Oracle Application Developer's Guide - Advanced Queuing or Oracle Streams Advanced Queuing User's Guide and Reference, Distributed Management, Oracle Enterprise Manager Administrator's Guide, and Setting Up the Business Event System, Oracle Workflow Administrator's Guide.

To test your Business Event System setup, you can run the Workflow Agent Ping/Acknowledge workflow. See: Workflow Agent Ping/Acknowledge.
