Hi, I am using the tomcat manager to monitor the health of the tomcat server. I found that the session of JVM, it shown the following information: JVM Free memory: 38.13 MB Total memory: 111.18 MB Max memory: 1365.37 MB Is my tomcat in good condition or not? It seems that the free memory is only 38.13MB? I have added the following lines in my startup.sh export JAVA_HOME=/opt/jdk export JAVA_OPTS=-Xmx1536m export CATALINA_HOME=/opt/tomcat How to know whether my tomcat can use the memory or not?    More>>
