Note: Although you can enter a name for a new dbspace and view the names of existing dbspaces in the Informix DBSpace dialog, you cannot generate a dbspace from erwin Data Modeler. You must use the native tools supplied by Informix to add a dbspace.

When your target server is Informix, you can use the Comment tab in the Informix DBSpace dialog to add and specify the parameters for a dbspace in which to store Informix database tables, and to enter a comment for a dbspace.

The Comment tab contains the following options:

Comment

Type or change a comment for the dbspace.

*****

When your target server is Informix, you can use the UDP tab in the Informix DBSpace dialog to enter user-defined property values for a dbspace in which to store Informix database tables.

The UDP tab contains the following options:

Property

Displays the name of the user-defined property (UDP) associated with the dbspace. When you use the Command datatype for a UDP, the Property box is a button that you can click to launch a file or application that you enter in the Value box.

Value

If you use a default value when you add a UDP, the property value is automatically specified. Otherwise, you can Enter or select a property value depending on the value datatype:

• Enter the property value in the Value box for Integer, Real Number, and Text datatypes.
• Enter a date value; click to change the month, day, and year, or click to select a date for the Date datatype.
• Select a value from the Value list for the List datatype. For example, you can add a UDP to select the backup frequency such as "daily."
• Enter a system command or click to browse for a file or executable program for the Command datatype. For example, you can enter or select C:\Myfile.doc to launch the Microsoft Word document "Myfile.doc."

Opens the UDP Dictionary dialog.
