How to increase permgen space in tomcat

Tomcat is managed by this script file catalina.bat, dive inside the script, you will find out that catalina.bat always find and run the setenv.bat file to set the environment variables.

 

{$tomcat-folder}\bin\catalina.bat

 

//...

rem Get standard environment variables

if not exist "%CATALINA_BASE%\bin\setenv.bat" goto checkSetenvHome

call "%CATALINA_BASE%\bin\setenv.bat"

goto setenvDone

:checkSetenvHome

if exist "%CATALINA_HOME%\bin\setenv.bat" call "%CATALINA_HOME%\bin\setenv.bat"

:setenvDone

//...

 

 

2.1 To set the environment variable on Windows, create a setenv.bat manually, and put it into the ${tomcat-folder}\bin folder.

 

${tomcat-folder}\bin\setenv.bat

set JAVA_OPTS=-Dfile.encoding=UTF-8 -Xms128m -Xmx1024m -XX:PermSize=64m -XX:MaxPermSize=256m

P.S No double quotes, set JAVA_OPTS={value}.

 

2.2 Restart Tomcat, it will call the setenv.bat file to set the environment variable automatically.

 

{$tomcat-folder}\bin\catalina.bat restart
