Summary
This technical note describes the capabilities delivered in Reflection X 2008. Reflection X 2008 offers a feature set that enhances, but does not replace, Reflection X version 14.x. While Reflection X continues to provide the same features and functionality, Reflection X 2008 introduces PC X server features not available in Reflection X. This technical note describes the new features of Reflection X 2008 so that you can determine when it's best to use Reflection X 2008.
Reflection X 2008 and Reflection X
Both Reflection X 2008 and Reflection X are stand-alone PC X Servers. However, you can install and run both products on the same machine (within the terms of the Reflection X 2008 license agreement) because both applications run independently of each other. See Technical Note 2236 for more information.
Reflection X 2008 Features
Reflection X 2008 offers new features related to remote X application access, multi-platform support, suspending and resuming X application user interface, and collaboration.
Install and run Reflection X 2008 if you want to perform any of the following functions:
- Access X applications from remote sites over high-latency or low-bandwidth networks without incurring a huge performance penalty.
- Suspend the user interface (UI) to an X application, allowing it to continue running on the UNIX host, even after shutting down the PC workstation that launched the X application.
- Resume a suspended X application user interface.
- Transfer the user interface of a suspended X application to another workstation.
- Share the user interface of an X application with one or more users.
- Run X applications from a variety of PC workstation platforms including Windows XP/Vista, Linux, and UNIX.
Reflection X 2008 supports X11R6.9 (the latest X11 version), SSH, GLX*, and OpenGL.

Reflection X 2008 Requirements
Note the following requirements for Reflection X 2008:
- Reflection X 2008 requires Java 1.6 (a Java 1.6 JRE is packaged with the product) and a platform capable of supporting a Sun distribution of the Java 1.6 JRE.
- New features in Reflection X 2008 are supported by use of a distributed execution model. To enable this model, Reflection X 2008 implements a proprietary Domain environment that supports the management of servers and user accounts.
- Remote/low-bandwidth support requires that a component of Reflection X 2008 be installed on the UNIX server hosting the X client to enable compression.
- Features such as Session Transfer and persistence through a PC workstation restart require that Reflection X 2008 be installed on one or more middle-tier servers (may be the same host running the X client application).
* Note that due to limitations in the GLX specifications, neither session transfer nor sharing is supported for sessions running GLX client applications.
