WAR file is giving me out of memory error

Question

I am using tomcat 6 and the WAR file I have deployed is giving me out of memory error. I have installed tomcat6 using windows installer because of it I am unable to find any catalina.bat in tomcat6.0\bin folder where I can configure CATALINA_OPTS variable.

@JunedAhsan: Its giving me an error "out of memory permgen". — Sparkplug, May 23 '13 at 06:35

If you have trouble setting CATALINA_OPTS in tomcat installation, you can set it as a environment variable in windows.

UPDATE:

If the previous method is not working then you can create a file, setenv.bat in bin directory of tomcat.

And in that file you can put the arguments like:

 set CATALINA_OPTS= "JVM Conditions here"

This did the trick for me, try it out.

I have already set the CATALINA_OPTS and JAVA_OPTS as environment variable in windows. Still does not work for me. – Sparkplug May 23 '13 at 06:20
@McTavish: You have to change your server memory settings using this. – Ankit May 23 '13 at 07:14

If you are not able to find the catalina.bat then edit your tomcat6w.exe and add

-XX:+CMSClassUnloadingEnabled
-XX:+CMSPermGenSweepingEnabled
-XX:+UseConcMarkSweepGC
-XX:PermSize=128m
-XX:MaxPermSize=512m

You should change the “Xms” and “PermSize” value base on your server capability.

Once done with editing simply Restart Tomcat.

Hope it helps!
