The Databases tab in the Progress OpenEdge Application section of the Run Configurations or the Debug Configurations wizard lets you specify the OpenEdge database connections used by an ABL application launch configuration. See Progress OpenEdge Application settings for information about accessing the wizard.

The Databases tab functions like the Database connections preferences page in the Project Properties dialog, with two additional controls (Use project database connections and Show from project) available:

Control Purpose
Name (accessible from all tabs) (Required) Specifies the name of the launch configuration, which appears on menus and in the left pane of the Run Configurations or the Debug Configurations wizard.
Use project database connections Causes the configuration to use those connections that are used by the project specified on the Main tab for the configuration. Choosing this option disables filtering and selecting from the list.
Show selected/Show all/Show from project Filters the database connection list to show: only those connections that are currently used by the configuration; all available connections; or only those connections that are used by the project specified on the Main tab for the configuration.
Database connection list Lists available OpenEdge database connections, filtered according to the Show selected/Show all/Show from project selection. The launch configuration uses those entries that are checked.
Other controls Function as described in the Database Connections help for the Project Properties dialog.
Apply Saves the current launch configuration definition.
Revert Discards unsaved changes to the current launch configuration definition.
Run or Debug Runs the specified startup program or opens it in the Progress Developer Studio for OpenEdge Debugger.
