The System areas section contains information about the control area and the schema area.

Click either Control Area or Schema Area to see more information in the following sections: Summary details, Extent file details, and Extent file I/O details.
Note: Although it is possible to create application extents in the schema area, OpenEdge Management shows the schema area in the System area view. When best practices are followed and all application extents are placed in their own areas, the schema area stores only system information.
The data presented in the Control Area and Schema Area views come from the _AreaStatus, _FileList, and _ActIOFile VSTs.
