## Step 15 Setting Up the Business Event System

The Business Event System is an application service delivered with Oracle Workflow that uses Oracle Advanced Queuing (AQ) to communicate business events between systems. You need to perform this step only if you want to use event processing. See: Overview of the Oracle Workflow Business Event System and Managing Business Events.

To set up the Business Event System, perform the following steps:

1. If you want to communicate business events between the local system and external systems, create database links to those external systems.

2. If you want to use custom queues for propagating events, set up your queues.

3. Schedule a listener to monitor the standard WF_ERROR queue to enable error handling for the Business Event System. See: Setting Up Queues and Scheduling Listeners for Local Inbound Agents.

You can either create database links and set up queues manually, or use Oracle DBA Studio in the Oracle Enterprise Manager to perform these steps. Oracle DBA Studio allows workflow administrators to quickly and easily create and administer database links, queue tables, queues, and queue propagation without requiring knowledge of the SQL DDL commands. See: DBA Management Pack, Oracle Enterprise Manager Administrator's Guide.

Context: You need to perform this step only once.
