I am running a Tomcat8 server on linux (RedHat). The machine it runs on has a total of 15GB Ram of which i want to allocate 11GB to the tomcat server. Currently it only has 3.3GB avaialable for use.
I have openjdk 64 bit installed.
I am trying to set CATALINA_OPTS to -Xms512M -Xmx11g and the JAVA_OPTS to -d64 -Xms256m -Xmx12g.
I found several how-to's saying something about a setenv.sh or catalina.sh both of which I cannot find: neither under tomcat8/bin, catalina_home or catalina_base which both point to /root.
So how do I increase available memory for my Tomcat server?
Thanks!
It seems that catalina.sh is either no longer existent in the latest tomcat release or it has something to do with the fact that i am using a amazon vm and they have some kind of modified tomcat8 distribution what i would doubt.
Solution:
under usr/share/tomcat8/conf/ there is a tomcat8.conf file.
Adding the row JAVA_OPTS="-Xms1g -Xmx12g" did the trick.
