You have to change the values in the CATALINA_OPTS option defined in the Tomcat Catalina start file. To increase the PermGen
memory change the value of the MaxPermSize
variable, otherwise change the value of the Xmx
variable.
Linux & Mac OS: Open or create setenv.sh
file placed in the "bin" directory. You have to apply the changes to this line:
export CATALINA_OPTS="$CATALINA_OPTS -server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m"
Windows:
Open or create the setenv.bat
file placed in the "bin" directory:
set CATALINA_OPTS=-server -Xms256m -Xmx1024m -XX:PermSize=512m -XX:MaxPermSize=512m
