I've moved a Production application from Tomcat 5.5.23 to 6.0.29, and my question is - are my command line arguments/parameters still valid?

export JAVA_OPTS="-Xms1024m 
                  -Xmx2048m 
                  -XX:MaxPermSize=192m 
                  -XX:NewSize=251m 
                  -XX:MaxNewSize=251m 
                  -XX:PermSize=32m 
                  -XX:SurvivorRatio=5 
                  -XX:TargetSurvivorRatio=90 
                  -XX:+UseParNewGC 
                  -XX:ParallelGCThreads=8 
                  -Djava.awt.headless=true"

I'm gathering they are because the application is up and running, but I haven't had any luck turning up a definitive list - the windows server documentation is the top link when I google...

Those are the options for your JVM. to get the definitive list for the version you are running you can type java -h for the standard options and java -X for the non-standard options "the -X[X] options

+1: That explains why I couldn't find anything when I was googling. –  OMG Ponies Jul 28 '10 at 18:04
