Executing Commands in the Database Manager GUI 
Use
You can call all of the functions of the Database Manager using the menu bar at the top of the screen (
Screen Areas of the Database Manager GUI).Every time you select an option from a menu, a new window is opened in the display.
Procedure
To switch between multiple open windows, choose View ® Previous Window | Next Window | List of Windows.
A window is only closed by the Database Manager once you have made the required entries and confirmed them; that is, when the command has been executed.

Special Cases:
Changing the Log Mode and Changing Volume Parameters
As changing parameters in a parameter session and changing volume parameters or the log mode are mutually exclusive, if there is an active parameter session, you must first close the parameter session and can then change volume parameters or the log mode.
To do this, choose View ® All Windows. Select the entry for the parameter session and choose Close Window.
Proceed as described under
