On Oracle Solaris 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.

2.4.2.1. 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 platforms. 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 Trusted Extensions platforms, you must install SGD in a labeled zone. Do not install SGD in the global zone.

2.4.2.2. 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.

Note

The SGD Enhancement Module no longer provides functionality that is supported on Windows 7 and Windows XP platforms. These platforms are still supported as an application server platform, see Section 2.4.3, “Microsoft Windows Remote Desktop Services” .

2.4.3. Microsoft Windows Remote Desktop Services

SGD does not include licenses for Microsoft Windows Remote Desktop Services. If you access Remote Desktop Services 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.

Note

Before Microsoft Windows Server 2008 R2, Remote Desktop Services was called Terminal 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 SP1

  • Windows XP Professional SP3

On Windows 7 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.

2.4.3.1. 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.

2.4.3.2. Audio Recording Redirection

Audio recording redirection is supported for Microsoft Windows Server 2008 R2 and Microsoft Windows 7 application servers.

To record audio in a Windows Remote Desktop Services session, audio recording redirection must be enabled on the application server. By default, audio recording redirection is disabled.

To enable audio recording for Microsoft Windows 7 Enterprise application servers, you also need to add the following registry entry to the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp key.

"fDisableAudioCapture"=dword:00000000

2.4.3.3. Color Depth

SGD supports 8-bit, 16-bit, 24-bit, and 32-bit color depths in a Windows Remote Desktop Services session.

32-bit color is available on 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 Remote Desktop Session Host, SGD automatically adjusts the color depth to 8-bit.

2.4.3.4. 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.

2.4.3.5. Transport Layer Security

From Microsoft Windows Server 2003, you can use Transport Layer Security (TLS) for server authentication, and to encrypt Remote Desktop Session Host communications.

2.4.3.6. Network Level Authentication

If the Remote Desktop Session Host supports Network Level Authentication (NLA) using CredSSP, you can use NLA for server authentication.

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 and Telnet 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 Administration Guide for Release 4.7 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

2.4.4.1. X11 Software

SGD includes an X protocol engine (XPE) implementation based on the X.Org Foundation X Server release X11R7.6.

The XPE implementation is based on the following X.org foundation sources:

  • xorg-server 1.9.3

  • xrandr 1.3

  • xkeyboard-config 2.1

The following versions of X.org dependencies are used:

  • Mesa 7.9.2

  • pixman 0.20.2

2.4.4.3. Character Applications

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

2.4.5. Virtual Desktop Infrastructure

SGD uses a type of object called a dynamic application server to represent a virtual server broker (VSB). SGD uses the VSB to obtain a list of application servers that can run an application.

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

Integration with Oracle VDI is also supported by configuring a Windows application object, as described in the Oracle Secure Global Desktop Administration Guide for Release 4.7.

This release of SGD supports the following versions of Oracle VDI:

  • Oracle VDI 3.4.1

  • Oracle VDI 3.3.2
