I need to deploy a change to increase the size of the Java cache on at least 100 machines from 100MB, to 1000MB. The Java cache that is, not the browser cache. This can be set manually in the Control Panel applet. This is an old version, 1.6 Update 11, that is used for a special intranet app. Update 23+ is installed concurrently with 11. Does anyone know of a reg key or something else that can be done via command-line to force this? SCCM and/or GPO would be used. I'm also pushing a key to turn off "next-generation Java plugin" as below, so I suspect that there is, but alot of Googling hasn't turned up much. I seem to recall a switch that can be used to set the cache size when silently installing Java, but I'd rather not 'repair' the existing instance unless that's the only way.
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in\1.6.0_11]
"UseNewJavaPlugin"=dword:00000000

TIA for any suggestion

Why not just run your favoured registry/file/process monitor while you make the change, or take a 'Before' and 'After' snapshot with your favoured snapshot tool?

If I recall correctly, you can set the cache size of the Java VM by either setting it in the deployment.properties or by using the -Xms and -Xmx parameters described here: http://www.caucho.com/resin-3.0/performance/jvm-tuning.xtp

Hope this helps
