2.4. Application Requirements and Support

This section describes the supported platforms and requirements for displaying applications through SGD.

2.4.1. Supported Applications

You can use SGD to access the following types of applications:

  • Microsoft Windows

  • X applications running on Oracle Solaris, Linux, HP-UX, and AIX application servers

  • Character applications running on Oracle Solaris, Linux, HP-UX, and AIX application servers

2.4.2. Supported Installation Platforms for the SGD Enhancement Module

The SGD Enhancement Module is a software component that can be installed on an application server to provide the following additional functionality when using applications displayed through SGD:

  • Advanced load balancing

  • Client drive mapping ( UNIX® or Linux platforms only)

  • Seamless windows (Windows platforms only)

  • Audio (UNIX or Linux platforms only)

The following table lists the supported installation platforms for the SGD Enhancement Module.

Operating System

Supported Versions

Microsoft Windows (64-bit)

Windows Server 2008 R2

Microsoft Windows (32-bit and 64-bit)

Windows Server 2008

Windows Server 2003 R2

Windows Server 2003

Oracle Solaris on SPARC platforms

8, 9, 10, 10 Trusted Extensions

Oracle Solaris on x86 platforms

10, 10 Trusted Extensions

Oracle Linux (32-bit and 64-bit)


SUSE Linux Enterprise Server (32-bit and 64-bit)

10, 11

Oracle products certified on Oracle Linux are also certified and supported on Red Hat Enterprise Linux due to implicit compatibility between both distributions. Oracle does not run any additional testing on Red Hat Enterprise Linux products.

On Oracle Solaris 10 Trusted Extensions platforms, only advanced load balancing is supported. Audio and CDM are not supported.

Application servers that are not supported platforms for the SGD Enhancement Module can be used with SGD to access a supported application type using any of the supported protocols. Virtualization Support

The supported installation platforms for the SGD Enhancement Module are supported on a Type 1 (bare metal) hypervisor or a Type 2 (hosted) hypervisor, for example Oracle VM VirtualBox, VMWare, or Oracle VM Server for SPARC (previously called Sun Logical Domains or LDoms).

Installation in zones is supported for Oracle Solaris 10. SGD can be installed in the global zone, or in one or more non-global zones. Installation in both the global zone and a non-global zone is not supported.

On Oracle Solaris 10 Trusted Extensions platforms, you must install SGD in a labeled zone. Do not install SGD in the global zone. Retirements to Supported Installation Platforms for the SGD Enhancement Module

The following table shows the installation platforms for the SGD Enhancement Module that have been retired.

SGD Version

Platforms No Longer Supported


OpenSolaris (all versions)

Windows Vista Business

Windows Vista Professional

Windows XP Professional


Fedora Linux 8

Red Hat Enterprise Linux 4

SUSE Linux Enterprise Server 9

SUSE Linux Enterprise Server 10

Windows 2000 Server


The SGD Enhancement Module no longer provides functionality that is supported on Windows Vista and Windows XP platforms. These platforms are still supported as an application server platform, see Section 2.4.3, “Microsoft Windows Terminal Services” .

2.4.3. Microsoft Windows Terminal Services

SGD does not include licenses for Microsoft Windows Terminal Services. If you access terminal server functionality provided by Microsoft operating system products, you need to purchase additional licenses to use such products. Consult the license agreements for the Microsoft operating system products you are using to determine which licenses you must acquire.


From Microsoft Windows Server 2008 R2, Windows Terminal Services is renamed Remote Desktop Services.

SGD supports RDP connections to the following versions of Microsoft Windows:

  • Windows Server 2008 R2

  • Windows Server 2008

  • Windows Server 2003 R2

  • Windows Server 2003

  • Windows 7 Ultimate

  • Windows 7 Professional

  • Windows Vista Ultimate

  • Windows Vista Business

  • Windows XP Professional

On Windows 7, Windows Vista, and Windows XP platforms, only full Windows desktop sessions are supported. Running individual applications is not supported. Seamless windows are also not supported.

The features supported by SGD depend on whether you connect using RDP or Oracle VM VirtualBox RDP (VRDP), as shown in the following table.

Table 2.1. Comparison of Features Supported by SGD When Using RDP and VRDP




Audio recording (input audio)

Audio redirection

Clipboard redirection

COM port mapping


Drive redirection (client drive mapping)


Network security (encryption level)

Session directory

Smart card device redirection

Time zone redirection

USB device redirection

Video acceleration

Windows printer mapping (client printing) Audio Quality

Windows Server 2008 R2 and Windows 7 support audio bit rates of up to 44.1 kHz. By default, SGD supports bit rates of up to 22.05 kHz. To support bit rates of up to 44.1 kHz, in the Administration Console go to the Global Settings, Client Device tab and select the Windows Audio: High Quality option. Color Depth

SGD supports 8-bit, 16-bit, 24-bit, and 32-bit color depths in a Windows Terminal Server session.

32-bit color is available on Windows Vista, Windows Server 2008, Windows Server 2008 R2, and Windows 7 platforms. To display 32-bit color, the client device must be capable of displaying 32-bit color.

15-bit color depths are not supported. If this color depth is specified on the Terminal Server, SGD automatically adjusts the color depth to 8-bit. Encryption Level

You can only use the Low, Client-compatible, or High encryption levels with SGD. SGD does not support the Federal Information Processing Standards (FIPS) encryption level. Transport Layer Security

From Microsoft Windows Server 2003, you can use Transport Layer Security (TLS) for server authentication, and to encrypt Terminal Server communications. SGD does not support the use of TLS.

2.4.4. X and Character Applications

To run X and character applications, SGD must be able to connect to the application server that hosts the application. SGD supports SSH, Telnet, and rexec as connection methods. SSH is the best for security.

SGD works with SSH version 2 or later. Because of SSH version compatibility problems, use the same major version of SSH, either version 2 or version 3, on all SGD hosts and application servers.

If you are using SSH to connect to X applications, you must enable X11 forwarding. You can do this either in your SSH configuration or by configuring the application in SGD. The Oracle Secure Global Desktop 4.6 Administration Guide has details on using SSH with SGD.

SGD supports the X Security extension. The X Security extension only works with versions of SSH that support the -Y option. For OpenSSH, this is version 3.8 or later Supported X Extensions

SGD includes an X server, based on X11R6.8.2.

SGD supports the following X extensions for X applications:






  • Extended-Visual-Information

  • GLX





  • RDP







  • SYNC


  • X-Resource




  • XFree86-Bigfont



The following X extensions are not supported:




  • XVIDEO Character Applications

SGD supports VT420, Wyse 60, or SCO Console character applications

2.4.5. Virtual Desktop Infrastructure

In SGD version 4.60, a new type of object called a dynamic application server was introduced. A dynamic application server is an object that represents a virtual server broker (VSB). SGD uses the VSB to obtain a list of application servers that can run an application.

SGD includes a VDI broker that enables you to give users access to desktops provided by an Oracle Virtual Desktop Infrastructure (VDI) server.

The following versions of VDI are supported:

  • Oracle VDI 3.2.2

  • Sun VDI 3.1.1

See Oracle Support Knowledge Document 1373652.1 if you want to use SGD with other versions of VDI.
