Copyright © 2009, Oracle. All rights reserved Creating a Process Flow Component Palette containing the process flow activities. Here you design the process flow. The START1 and END_SUCCESS activities are added automatically. Property Inspector shows the properties of the current activity. You can drag existing mappings directly on the canvas. Structure panel provides the current activity's parameters. You can generally set its values in the Property Inspector panel.

Copyright © 2009, Oracle. All rights reserved Manual Activity The manual activity indicates that the process flow would be halted until a manual response is performed by a person. The user can respond to the manual activity in the Control Center or in the Repository browser, and define the result ( SUCCESS, WARNING, or ERROR ). The process flow continues accordingly.

Copyright © 2009, Oracle. All rights reserved SQLPLUS Activity With the SQLPLUS activity, you can run any (parameterized) SQL*Plus script from within a process flow. Parameter_List: In the Value property, followed by the full path of the location of the file containing the script. Script: Alternatively, enter or paste the script in the Value property.

Copyright © 2009, Oracle. All rights reserved Activity You can send notifications after the completion of an activity in a process flow.

Copyright © 2009, Oracle. All rights reserved Some More Activities File Exists: Used to verify the existence of a file before running the next activity FTP: Used to transfer files from one file location to another based on a script of FTP commands that you provide. Sub-Process: Used to start a previously created process flow. From one process flow, you can start any other process flow that is contained within the same or any other process flow package.
