## To Start a Background Engine

If you are using the standalone version of Oracle Workflow, then use the `WF_ENGINE.BACKGROUND`( ) API to start up a background engine. Sample scripts that repeatedly run the background engine are provided with the standalone version of Oracle Workflow. See: Background.

If you are using the version of Oracle Workflow embedded in Oracle Applications, you can start a background engine by submitting the Background Process concurrent program using the Submit Requests form. See: To Schedule Background Engines

> Note: Make sure you have a least one background engine that can check for timed out activities and one that can process deferred activities. At a minimum, you need to set up one background engine that can handle both timed out and deferred activities.
