Optimize Java Desktop System 2 for Sun Ray

You might have heard that Sun Ray Server Software 3.0 will run on both Solaris and GNU/linux. You might also know that Sun's Java Desktop System 2.0 (JDS 2) is built around a GNU/linux kernel. So you might wonder why you can't run Sun Ray Server Software 3.0 on JDS 2 and serve this alternative desktop to multiple users on Sun Ray ultrathin clients. Well, you can. Here is a tech tip which explains how to install and optimize JDS 2 for use with Sun Ray Server Software 3.0

Step 6 of the above howto refers to the Java Desktop System online update. Here are some details on exactly how to apply the update and which updates are applicable to Sun Ray environments:

First, launch the Java Desktop System online update utility (jsupdate). If this is the first time you've run it, online update will ask for your serial number and then download an update for itself. The next time you run the online update utility you will see a list of available updates. I would recommend applying all of them, but at the very least, apply the security updates and those which improve Sun Ray/multiuser performance such as:
  • 118904-02 Recommended update for gnome-session This patch allows the user to disable the logout fade effect. This improves logout responsiveness on Sun Ray and other thin client environments, especially over broadband/WAN connections.
  • 118906-01 Recommended update for metacity This patch provides Wireframe window-move mode. This is particularly useful for improving Sun Ray performance over broadband and wide area networks.
  • 119477-01 Recommended update for Evolution This solves a problem which causes the Evolution wombat process to remain running after logout. This and the related bonobo reference leak caused inefficient resource usage on multiuser environments (e.g. Sun Ray.) And could cause failures on relogin.
