Change JVM parameters for NetBeans

To change the JVM parameters for NetBeans so that it runs better (in case you have hardware), go to Netbeans installation directory and find the netbeans.conf file inside the /etc dir:

C:\NetBeans-7.0.1\etc\netbeans.conf

Open the file netbeans.conf and find netbeans_default line:

netbeans_default_options="-J-server -J-Xss4m -J-Xms256m -J-XX:PermSize=64m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

I changed mine to include some additional JVM parameters. Also, note that I changed the mode from -client to -server (it runs better in my notebook's hardware I guess :-).

So the new JVM parameters are:

-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m

The complete line:

netbeans_default_options="-J-server -J-Xms128m -J-Xmx512m -J-XX:+UseConcMarkSweepGC -J-XX:+UseParNewGC -J-XX:ParallelGCThreads=4 -J-XX:+CMSParallelRemarkEnabled -J-XX:NewSize=64m -J-XX:MaxNewSize=64m -J-XX:+DisableExplicitGC -J-XX:PermSize=64m -J-XX:MaxPermSize=256m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

Enjoy the better performance! :-D

How to change NetBeans language (locale)

I am not used to any IDE in Portuguese (my native language) so I do not like to use the NetBeans interface in Portuguese.

So, in order to change that:

Go to Netbeans installation directory and find the netbeans.conf file inside the /etc dir:

C:\NetBeans-7.0.1\etc\netbeans.conf

Open the file netbeans.conf and find netbeans_default line and just add "-J-Duser.language=en -J-Duser.region=US" at the end of this line and restart NetBeans.

netbeans_default_options="-J-client -J-Xss4m -J-Xms256m -J-XX:PermSize=64m -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Duser.language=en -J-Duser.region=US"

That is it! :-D

My JBoss Middleware Placement Exam certification

My SAP Netweaver Instructor certificate

My Sun Certified Associate for the Java 2 Platform 1.0 certification

My Sun Certified Mobile Application Developer for the Java 2 Platform Micro Edition 1.0 certification

My Sun Certified Web Component Developer for J2EE Platform 1.3 certification

My Sun Certified Business Component Developer for J2EE Platform certification

My Sun Certified Programmer for Java 2 Platform certification

My Sun Certified Enterprise Architect for J2EE Platform report

Strangely Security and Legacy Security were the worst scores.

I find it funny because that is where I have the best knowledge and experience in Java EE. The point here is that such topics have just a few (2 or 3) questions in the exam and if you provide one wrong question it is half the total :-)

I know I am a certified Architect at least!!! ;-)
