1.3 Using Applications

Use the Applications area of the workspace to start, stop, and manage your applications.

1.3.1 Running Applications

To start an application, you click its link on your workspace, as shown in Figure 1.10, “Workspace Link for Running an Application”. In a few moments the application is shown, ready for you to use.

Figure 1.10 Workspace Link for Running an Application

Workspace Link for Running an Application

When you start an application, you might be asked for a user name and password. This is your user name and password for the application server that runs the application.

You do not have to exit an application before starting another. Just click another link.

SGD Administrators configure how the applications display.

If you have difficulties, contact your SGD Administrator.

1.3.1.1 Number of Instances of an Application

When an application is running, a triangle appears in front of the application's name on the workspace and a number appears in brackets after it. The session toolbar also appears below the application name. The session toolbar is used to suspend, resume, or end an application. Figure 1.11, “Workspace Link When the Application is Running” shows the workspace link when two instances of an application are running.

Figure 1.11 Workspace Link When the Application is Running

Workspace Link Details When an Application is Running

The number in brackets is the number of separate instances of the application that you have started. SGD Administrators configure how many instances of an application you can start.

To find out how many instances of an application you are allowed, point to its link on the workspace. The popup that is displayed states the number of sessions allowed.

See Section 1.3.2, “Suspending and Resuming Applications” for more details.

1.3.1.2 What If I Get an Error Message When Starting an Application?

If an error message is shown when you click a link to start an application, try one of the following:

  • Make sure you supplied the correct user name and password for the application server. If SGD does not prompt you for this information, hold down the Shift key and click the link to force the prompt to appear.

  • Log out of SGD and exit your browser, then restart it and log in to SGD again. Click the application's link.

  • Contact an SGD Administrator, supplying all the information shown in the error message.

1.3.1.3 What If a Chooser Page is Displayed When I Start an Application?

When you click the link to start an application, a chooser page might be shown in the Information area.

Depending on how the application is configured, you can use the chooser page to select the application server that runs the application, or to select the application that is started, or both.

Figure 1.12 Chooser Page, Selecting an Application Server

Chooser Page, Selecting an Application Server

The chooser page is not displayed automatically for all applications. It must be configured by your SGD Administrator.

1.3.2 Suspending and Resuming Applications

Some applications can be configured to keep running, even when they are not displayed. These are called resumable applications.

To close an application's window without ending the application, you suspend the application. To display the window again and start using the application, you resume the application.

As an application is still running even though it is not displayed, you can start writing an urgent report in the office and then log out of SGD at the end of the day. The application is suspended. When you get home, you can log in to SGD again, resume the application and carry on writing the report.

Suspending and resuming applications is done using the session toolbars on the workspace.

1.3.2.1 Session Toolbars for Controlling an Application

There is a separate session toolbar for each running instance of the application:

  • Click Suspend Button  to suspend an application

  • Click Resume Button  to resume an application

  • Click Cancel Button  to end an application

Click the triangle to hide and show the session toolbars for the application sessions, as shown in Figure 1.13, “Session Toolbar when Hidden”.

Figure 1.13 Session Toolbar when Hidden

Hidden Session Toolbar

You can manage all your application sessions at once, using the following links at the top of the Applications area:

  • Click the Suspend All link to suspend all running applications

  • Click the Resume All link to resume all suspended applications

  • Click the Cancel All link to end all running or suspended applications

1.3.2.2 Resumability Settings for Applications

To see if an application is resumable or not, point to its link on your workspace and look at the popup window that is displayed.

The available resumability settings for an application are described in the following table.

Resumability Settings

Description

Not Resumable

This application exits when you log out of SGD. You cannot suspend or resume non-resumable applications.

Note

Non-resumable applications only have a Cancel button in the session toolbar.

Resumable Until Log Out

This application continues running until you log out of SGD. While you are logged in, you can suspend and resume these applications.

Always Resumable

This application continues running even after you have logged out of SGD. When you log in again, click the Resume button to display the running application again.

Note

If you log in to SGD without entering a user name and password, resumable applications are only resumable until you log out.

1.3.2.3 Do I Lose My Work If I Close My Browser?

No, you do not lose any work if you accidentally close your browser without logging out, or if your browser crashes. You can restart your browser and log in to SGD to display your workspace.

However, if the SGD Client exits unexpectedly, or if you close down the SGD Client, your ability to resume an application depends upon how your SGD Administrator configured the application and how you logged in to SGD.

  • If an application is configured to be “Not Resumable”, then it exits when the SGD Client exits or is closed down. Typically, applications are configured to be Not Resumable if they are used only for short periods at a time, and are not business-critical functions.

  • Applications configured to be “Always Resumable”, or “Resumable Until Log Out”, continue to run for a period of time after an SGD Client exits or is closed down. Simply restart your browser, log in to SGD again and resume the applications that are still running.

  • If you logged in to SGD anonymously, in other words you did not supply a user name and password, or you are using a shared workspace, where more than one person logs in using the same user name and password, then your applications exit if the SGD Client exits or is closed down. In both cases, the reason for this is that SGD cannot tell when you log in to SGD again that you are the same user as before, because you are not using a unique user name and password. See also Section 1.2.4.1, “User Name”.

1.3.3 Changing the Way an Application is Displayed

Your SGD Administrator defines how an application is displayed on your desktop. For example, if the application is displayed full-screen or in a desktop window.

A graphical application that is displayed in a desktop window can be scaled to fit the size of the window. If you resize the window, SGD rescales the application to fit the new window size, without displaying any scroll bars.

You can switch the application between being scaled and not being scaled by pressing the Scroll Lock key.

To see if an application is displayed in a scalable window, point to its link on your workspace and look at the popup that is shown. Alternatively, look in the status bar at the bottom of the window.

1.3.4 Copying Information Between Applications

For Windows applications and X applications, use the normal method for the application you are copying from, and then the usual method for the application you are pasting to. You might not be allowed to copy and paste information from particular applications. This is configured by your SGD Administrator. If you are not allowed to copy and paste between an application, the following message is pasted instead of the information you copied:

Oracle Secure Global Desktop Software: Copied data not available to this application

For character applications, click with the right mouse button, and then click Copy or Paste as appropriate. To select a column of text, hold down the Shift key while selecting the text.

You can copy information between different types of application, for example from an xterm running on an application server to a text editor running on your computer.

You can only copy and paste graphics to or from Windows applications.

1.3.5 Running Applications Using a Different User Name and Password

To force SGD to prompt you for a user name and password when you start an application, hold down the Shift key when you click the application's link on your workspace. This is called forced authentication.

Forcing SGD to prompt you for a user name and password in this way means that SGD does not use any user name and password that has already been saved for the application server. This is useful if you want to run an application as another user.

If the Save This Password check box is selected, the new user name and password are saved, replacing any previously saved user name and password for you on the application server. This user name and password is then used for any other applications you run on the application server.

Saving of passwords can be overridden, using the Password Preferences feature. See Section 1.5.3, “Password Preferences”.

Holding down the Shift key has no effect when you are logged in to SGD anonymously, or as a shared user.

To use forced authentication on the tablet workspace, see Section 2.4.1.1, “Using Forced Authentication on the Tablet Workspace”.

1.3.6 Using a Single-Button Apple Macintosh Mouse

Many Microsoft Windows applications and X applications make use of a middle mouse button or a right mouse button. To use these applications from an Apple Macintosh mouse with one button, click the button while holding down one of the following keys on the keyboard:

  • To simulate a middle mouse button click, press Alt while clicking the mouse button

  • To simulate a right mouse button click, press Command while clicking the mouse button

Tip

Ensure that three-button mouse emulation is enabled in the X11 Preferences settings for your computer.
