I'm having some problems with Tomcat. I'm deploying a Grails application and as I were adding new features I got this (sadly well known) error in the stacktrace file:

Caused by: java.lang.OutOfMemoryError: PermGen space

I have an Windows installer-based tomcat installation and I don't have an catalina.bat file also. Googling many pages suggest to modify this file (catalina.bat) or register JAVA_OPTS variable, but nothing works. So, where do I have to specify this parameters?:

SET JAVA_OPTS="-Dfile.encoding=UTF-8 -server -Xms512m -Xmx1024m -XX:NewSize=256m -XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m -XX:+DisableExplicitGC”

I have tried to modify the Java Options through Apache Tomcat 7 Properties window but after the modifications the server can't start.

tomcat java configuration tab

My computer has 4Gb RAM installed.

Thanks in advance.

For the following system specifications:

  • Windows 7 64-bit
  • 4 GB installed RAM
  • Intel Core i7 processor
  • Java(TM) SE Runtime Environment (build 1.6.0_25-b06)

The Tomcat 7 Java properties for an acceptable behavior MIGHT be: tomcat java configuration

You should have a small windows application 'tomcat6w.exe' or 'tomcat7w.exe' when tomcat was installed as a windows service. When you start this application it has a tab 'Java' where you can set the JVM parameters. For more details see more memory to Tomcat service.

You need to enter only the parameters which start with -X.

This work for me in apache-tomcat-8.0.15, but i think it would be the same for all to tomcat's version.

I had executed regedit and found this path:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tomcat8

And change ImagePath key to:

C:\apache-tomcat-8.0.15\bin\tomcat8.exe //RS//Tomcat8 ++JvmOptions -XX:PermSize=128m -XX:MaxPermSize=512m
