Increasing memory in the Sun Java Plugin
(This information is from the University
of Wisconsin AniS page, with
some addenda by me.)
You can increase the amount of memory available to the
display applet by following these steps.
- Normally, you should first, shut down (exit) your browser(s). The
exception to this is if you already are running a newer version of the Java
Plug-in on Windows, and when you right-click the Java icon in the taskbar,
you get the option "Open Control Panel". If you do, just click on it, and
jump to Step #3.
- Then run the "Java(TM) Plugin Control Panel"
- On a Mac: Use "Finder" to get to: Applications -> Utilities -> Java
and then, run the Java Plugin 1.4.x Setup or whatever version
you have.
- On a Windows machine, Start -> Control Panel -> Java
- On Linux, locate the shell script ControlPanel in the Java install's bin/
directory and run it. (You may be able to do this by typing
"locate ControlPanel" on the command line.)
- Click on "Advanced" (or, on a Mac, the "General" tab), and in the space provided under
"Java Runtime Parameters", please type the following (exactly as shown):
-Xmx128m
Then click "Apply" button (or "Apply Now" on a Mac).
These steps will allow your browser that uses the Plugin to run Java to use up to 128MB of
memory. This seems to be near the current maximum allowed by Internet
Explorer. However, you can increase the memory value to 256 MB
(-Xmx256m) if you are using the
Firefox Browser. Higher values may
cause the plugin to not function. You will need to do this every time
you update the Java Plugin, as well.
