[Deploying Sakai] Java Out of Memory Error with Sakai 2.5 on Windows

[Matthew Jones]

This is my setenv.bat on the windows QA-6 server, it's pretty minimal
and matches the install guide. It is in the tomcat/bin directory. I
was able to start it up with or without double quotes. You'd probably
want to remove the -Dsakai.security or -Dsakai.home (or at least
change them to point to where your sakai.properties and/or
security.properties files are)

I'm starting up tomcat from a windows service. I don't have any
environment variables set that would alter these settings. I know it
*seems* obvious I'd make sure it *really* is a .bat file as windows I
remember making it as a text file editing it and being annoyed it
wasn't seeing it for a few minutes at one time (since it hides the
.txt extension by default). That seems to happen to me often in
windows. :/

The server sounds about the same 4gb of ram. After startup tomcat5 is
using 415,114K.

setenv.bat
--------------
set JAVA_OPTS=-server -XX:+UseParallelGC -Xmx1024m
-XX:MaxPermSize=160m -Djava.awt.headless=true -Dsakai.demo=true
-Dsakai.security=C:\inetpub\tomcat\security
-Dsakai.home=C:\inetpub\tomcat\sakai
