• Run the Tomcat Monitor
• Open the Tomcat Monitor system tray Configure … menu
• Select the Java tab
• Set the Initial memory Pool (see table above)
• Set the Max Memory Pool (see table above)
• Add the following lines to the Java Options scrollable field:

-Xms1024m
-Xmx1024m
-verbose:gc
-Djava.awt.headless=true

If you have installed the scripts in tomcat login scripts, these option will already be set however for clarity, these options are defined in the JAVA_OPTS environment variable set in the tomcat user’s shell startup file (e.g. .profile / .bash_profile / .cshrc in the user’s home directory – the actual startup file is determined by the user’s default shell settings).

JAVA_OPTS=’'-Xms1024m -Xmx1024m -verbose:gc -Djava.awt.headless=true’true'
