This section explains how to publish applications (including Java and legacy applications), shell scripts, and server desktops. It also explains how to publish applications on UNIX servers of different architecture, change the working directory, and configure the server to accept published application parameters passed by the client.

Publishing an Application

Use the ctxappcfg command to publish an application. The command prompts you for the information required to publish the application.

Application installation is not part of the application publishing process. Before an application can be published, both Presentation Server and the application must be installed. The order in which you install the application and Presentation Server does not matter. After an application is installed, it can be published at any time.

To publish an application

1. Log on to the server as an administrator. 2. At a command prompt, type ctxappcfg.

The following prompt appears:

App Config>

3. At the App Config prompt, type publish. You are prompted for each item of information you need to supply:

At the prompt for Specify Default

Name The name you want to use for the published application. The user selects this name when setting up an ICA connection to this published application. The name does not need to be the same as the name of the executable file for a particular program.

No default

Command-line The command-line required to run the application or script file; for example: /usr/ bin/diary.bin.

No default

Working directory The default working directory. This directory must exist. Leave blank to specify the user’s home directory. Note that ~/sub- dir is supported; ~otheruser is not.

User’s home directory

Anonymous

[yes|no] yesonly, or if the application is for anonymous use no if it is for use by users with explicit accounts only.

No default

Description An optional description that appears on the user’s Web page. This information is required for applications accessed using the Web Interface.

Blank

Folder A folder containing the application. This information is required for applications accessed using the Web Interface.

Blank

Icon File The icon file displayed against a published

application in the Web Interface. ICA icon Window Size The window size and type of window. This

information is required for applications accessed using the Web Interface. Specify window size as: widthxheight, for example, 1024x768; or % (percentage) of a desktop, for example, 70%.

Specify type of window as seamless (the window size is controlled by the client) or

fullscreen (full screen display).

800 x 600 pixels

4. At the App Config prompt, type exit.

The published application is enabled automatically. You can now connect to the server from a client and set up a connection to this published application.

Color Depth The number of colors used to display the application. Choose from 16, 256, 4bit, 8bit,

16bit, and 24bit. This information is required for applications accessed using the Web Interface.

256 colors

Enable SSL

security yesapplication, or to use SSL to secure connections to this no if you do not want to use SSL.

Controlled by default settings User name The user names of users permitted to access

this application. Type one user name per line. Leave a blank line to complete the list.

No default

Group name The names of user groups or netgroups permitted to access this application. Type one group name per line. Leave a blank line to complete the list. To denote a netgroup, use an @ as the first character of the name; for example @netgroup1.

No default

Server name The names of servers in the farm that will publish this application. Type one server name per line. Leave a blank line to complete the list. To specify all current servers in the farm, type an asterisk (*). To specify all current and future servers in the farm, type a plus sign (+).

No default

Note

• Increasing window size and color depth increases demand upon memory. For example, an ICA connection configured to run at a color depth of 256 colors and window size of 4096 x 4096 uses

approximately 16MB of memory just for the ICA session (additional memory is required for the applications). An ICA connection

configured to run at the same window size but at a color depth of 24-bit True Color uses approximately 64MB of memory. Consequently, as memory consumption increases, it may not be possible to run as many concurrent sessions without increasing memory.

• If you specify a netgroup, only the presence of a user in a netgroup is checked; the host and domain fields are ignored.

You can change the configuration of a published application at any time; see “Changing the Settings of a Published Application” on page 74 for more details. When you first publish an application, you can specify display settings for folder, icon, window size, and color depth. If you do not configure these display settings, default display settings are used. You can change the default display settings for all published applications in the server farm; for more information, see

“Specifying Default Settings for Published Applications” on page 77.
