App Server Default files to find JVM options

TomEE+

 INSTALL-DIR/bin/Catalina.sh

All files are startup scripts or batch files. For all servers, edit the startup file and locate the Java command line.

Following is an example from the tomcat.sh file:

$JAVACMD $TOMCAT_OPTS -Djava.security.manager 
-Djava.security.policy==${TOMCAT_HOME}/conf/tomcat.policy 
-Dtomcat.home=${TOMCAT_HOME}  org.apache.tomcat.startup.Tomcat
"$@" &
Note: The TOMCAT_OPTS environment variable can be used to pass in JVM options. It is necessary to check both the command line itself and the TOMCAT_OPTS environment variable to verify the JVM options in use.
