Configuring Character Applications

You use a character application object if you want to give a VT420, Wyse 60 or SCO Console character application to users.

This page includes the following topics:

Configuring Character Application Objects

In the SGD Administration Console, the configuration settings for character application objects are divided into the following tabs:

The following table lists the most commonly used settings for configuring character application objects and how to use them.

Tab Attribute Description
General Name The name that users see.
General Icon The icon that users see.
Launch Application Command The full path to the application that runs when users click the link.

The application must be installed in the same location on all application servers.

See also how to configure VMS character applications.
Launch Arguments for Command Any command-line arguments to use when starting the application.
Launch Connection Method The mechanism SGD uses to connect to the application server.
Launch Number of Sessions The number of instances of an application a user can run. The default is three.
Launch Application Resumability For how long the application is resumable. The following options are available:
  • Never - the application can never be resumed
  • User session - the application keeps running and is resumable until the user logs out of SGD
  • General - the application keeps running for a time (controlled by a timeout) after the user logs out of SGD, and can be resumed when the user next logs in
Launch Window Close Action what happens if the user closes the main application window using the Window Manager decoration. This attribute only applies for applications that use an Independent Window.
Presentation Window Type How the application is displayed to the user.

If Independent Window is selected, you must specify a Height and Width for the Window Size or select the Client's Maximum Size check box.

Specify the number of Columns and Lines to display in the terminal window.
Presentation Emulation Type The type of character application to emulate. SGD supports VT420, Wyse 60 or SCO Console character applications.
Presentation Terminal Type The application's terminal type. Accept the default terminal type or type you own type in the Custom field.
Performance Application Load Balancing How SGD chooses the best application server to run the application.

See Application Load Balancing for more details.
Hosting Application Servers Editable Assignments Use the Editable Assignments table to select the application servers, or group of application servers, that can run the application.

The application must be installed in the same location on all application servers
Assigned User Profiles Editable Assignments Use the Editable Assignments table to select the users that can see the application. Selecting Director or Directory (light) objects allows you to give the application to many users at once. You can also use an LDAP directory to assign applications.

In addition to this configuration, you might want to configure the following:

To use and display the euro character, the terminal session must be capable of displaying 8-bit characters. To ensure this, enter the command stty -istrip. Also, the client device must be capable of entering the euro character.

Creating Character Application Objects on the Command Line

On the command line, you create an X application object with the tarantella object new_charapp command. You can also batch-create multiple character application objects with the tarantella object script command.

Character application objects can be created only in the o=applications organizational hierarchy.
