By default, Tomcat assigned very little memory for the running process, you should increase the memory by make change in catalina.sh or catalina.bat file.

1. Open “catalina.sh” file. Cataline.sh is located at \tomcat folder\bin\catalina.sh
2. Assign following line to JAVA_OPTS variable and add it into catalina.sh file.
   JAVA_OPTS="-Djava.awt.headless=true -Dfile.encoding=UTF-8
-server -Xms1536m -Xmx1536m -XX:NewSize=256m
-XX:MaxNewSize=256m -XX:PermSize=256m -XX:MaxPermSize=256m
-XX:+DisableExplicitGC"
3. Change the “Xms” and “PermSize” value base on your server capability.
4. Restart Tomcat.

How can i do this in windows tomcat? I can't find catalina.sh file in \tomcat folder\bin\. There are just tomcat5.exe, dll, and jar files.
