Secure Global Desktop 4.40 Administration Guide > Applications, Documents, and Application Servers > Configuring X Applications
You use an X application object if you want to give an X11 graphical application to users.
This page includes the following topics:
In the SGD Administration Console, the configuration settings for X application objects are divided into the following tabs:
The following table lists the most commonly used settings for configuring X application objects and how to use them.
|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.
The following are commonly used commands for desktop sessions:
|Launch||Arguments for Command||Any command-line arguments to use when starting the application.
Note Never specify a
|Launch||Connection Method||The mechanism SGD uses to connect to the application server, for example telnet or ssh.|
|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:
|Launch||Session Termination||The circumstances when the SGD server ends the application session.|
|Presentation||Window Type||How the application is displayed to the user.
Use Kiosk for full-screen desktop sessions. Selecting the Scale to Fit Window check box for the Window Size allows SGD to scale the application window to fit the client device display.
Use Client Window Management to display the application as though it is running on the client device.
For other window types, you must specify a Height and Width for the Window Size or select the Client's Maximum Size check box.
|Presentation||Color Depth||The application's color depth.
SGD supports X applications with multiple color depths, for example so you can run an 8-bit application within a 24-bit desktop session by selecting 24/8-bit.
|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 do the following:
On the command line, you create an X application object with the
tarantella object new_xapp command.
You can also batch-create multiple X application objects with
tarantella object script command.
X application objects can only be created
o=applications organizational hierarchy.
SGD supports the following X extensions for X applications:
The following X extensions are not supported:
SGD includes the standard X Window System fonts in compiled
.pcf) and compressed form, together with some additional
fonts required by different UNIX systems.
See Fonts in X11R6.8.2 for details.
The fonts are installed in the
You can also configure SGD to use your own X fonts.
The following X fonts and font directories are available:
|75dpi||Variable-pitch 75 dpi fonts.|
|100dpi||Variable-pitch 100 dpi fonts.|
|andrew||Fonts from the Andrew toolkit, required by some IBM applications.|
|CID||This is a placeholder for CID-keyed fonts. If you want to add your own CID fonts for use with Secure Global Desktop install them in this directory.|
|encodings||Contains a set of encoding files used by the Type1 and TrueType font handlers|
|hp||Fonts required by some Hewlett-Packard applications.|
|icl||Fonts required by some ICL applications.|
|misc||Fixed-pitch fonts, cursor fonts, and fonts for compatibility with older versions of X.|
|oriental||Kanji and other oriental fonts.|
|TTF||True Type fonts.|
|Type1||PostScript Type 1 fonts.|
There are two ways to make your own X fonts available through SGD:
After making the X fonts available, configure each SGD server in the array as follows:
xset qcommand to see if the font path is set.
Each SGD server in the array can use a different font path. However, to avoid inconsistent display of applications, ensure that the same fonts (in the same order) are available to all SGD servers.
To use a font directory, copy your fonts in
.pcf format to a directory on
each SGD server in the array and include a
fonts.dir file that maps
filenames to X logical font descriptions.The fonts can be compressed or gzipped.
The following is an example line from a
If your font directory does not include a
you can use a program such as
mkfontdir (available for most
UNIX systems) to create one.
You can also include a
fonts.alias file, which
specifies aliases for the fonts in the directory. This file maps
aliases to X logical font descriptions. For example:
A font server is a program that makes fonts on a host available on the network. Font servers make font administration easier by centralizing fonts, reducing duplication.
To name a font server in a font path, you need to know the name of
the font server and the port on which fonts are being served. For
example, if the font server boston uses port 7000/tcp, add the font
