Parameters for Database Access Screen 

This screen allows you specify the HP TurboIMAGE/iX databases that may be
accessed by an application.  For each database, you must also specify the
user class password that the application will use to access the database.

You can access this screen from the DB Access option on the main menu.

Field Descriptions 

Application.  Enter the name of the application for which you wish to
specify the accessible databases.

When you commit this field, a list of all databases currently accessible
by the application is displayed on the screen.

List of Database Access Parameters.  The scroll area on the second half
of the screen contains a list of all databases accessible by the
application specified in the Application field.  If the list is too long
to be displayed on the screen, you can move through the list by using the
 Next  and  Previous  function keys.

The user class passwords are not displayed in the list, as a precaution
against unauthorised passers-by seeing the screen when it is displayed.
If you wish to see the user class password for a database, you must
complete the following fields:

Database Name.  Enter the name of a database accessed by the application.
This is the internal HP ALLBASE/4GL name of the database.  This database
must be defined on the database definition screen before any access
parameters can be set for the database.

After you enter this field, a window is displayed containing the database
access parameter fields relevant to the type of database indicated in the
Type field.  If the database name already exists on the list of
accessible databases, the window fields will contain the current values
set for the database.

Currently, only the HP TurboIMAGE/iX database window is displayed.


            

Database Type.  This is a display-only field which indicates the database
type.  A T in this field indicates that the database is an HP
TurboIMAGE/iX database.  A question mark (?)  in this field indicates
that the database definition has been deleted by the HP ALLBASE/4GL
administrator.  In this case, the database must be redefined on the
database definition screen before the application can access the
database.

Action.  Enter the code of the action to be performed on the specified
database.  Choose from one of the following:

Code                  Action                                                                                                         

A                     Add a database to the application.

C                     Change or view the database's access parameters.

D                     Delete a database from an application.

Password. 

Enter a password for an HP TurboIMAGE/iX user class.  The password must
be a valid user class password for the database, as defined by the HP
TurboIMAGE/iX administrator.  The password that you enter in this field
determines the read and write access permissions of the database for this
application, for all application developers and end users.

This field is optional, and if you leave the field blank, HP
TurboIMAGE/iX will interpret the access permissions to be those of user
class zero, which has no password.

A database password only applies to the specified application.  If a
database is accessed by more than one application, the password may be
different for each application.

Function Keys

        application definition screen.

the database is granted to the application on this screen.
