It came up last year that we needed to disable automatic updates for JRE and also we needed to disable the next-generation Java plug-in option included with JRE as it could under certain circumstances cause an FRM-92050 error in oracle Applications Java Forms.

Manually going to several hundred PCs to do that seemed a bit silly so I compiled the following VB script to take care of it automatically. The script can be deployed as part of GPO, a user login script or manually executed on each required PC.

This script is tested and working for the Oracle Java Runtime Environment 1.6.x.

Save the following as Oracle_JRE_Settings.vbs and execute away.  

Disclaimer: You execute this script at your own risk

' Oracle_JRE_Settings.vbs
' A script to enable or disable automatic Java Updating and to Enable or Disable Next-Generation Java Plug-In.
' For Oracle Applications 11i Next-Generation Java Plug-In should be disabled to avoid FRM-92050 errors.
' In an enterprise environment Automatic Java updates should be disabled.

I recently Installed the Windows 8 Developer preview. I installed it as a Dual boot with Windows 7. After installation Windows 8 takes over the boot process and if you wish to get access to 7 it increases your startup time annoyingly.

By default the installation is configured to boot windows 8 then you choose Windows 7 and the computer restarts into Windows 7. It's really easy to fix and give yourself the "old" dual boot menu. Saving precious seconds during boot up.

The inability to have stable video playback in Linux with the ATI Graphics Driver as always been a major gripe of mine. Video tearing has been a real irritating issue, but it appears that ATI may have finally solved the tearing problem. It only took forever and a day but none the less, I have just watched a DVD on my laptop with no tearing or other artifacts ruining the experience.

Some brief instructions on X11 forwarding/tunneling using SSH, PuTTY & Xming. These instructions also cover the commands required to forward X11 after you su to another user. I encountered a small but irritating issue launching the Oracle Universal Installer (OUI) when the E-Business Suite Applications Tier environment was set, so that solution is here too. Two methods are covered.

1. Using a direct X11 connection (Port 5900)
2. Tunneling the connection over SSH for that added bit of security and cutting down on the firewall ports you need to have opened.
