Question

I have a java-11 tomcat-9 stack app service. I want to setup xmx (max heap memory) to that.

How can I set that?

Sidepoints

• I went to ssh and tried printenv | grep JAVA but I could not find anything. However it prints following line in logs, that means it is taking it from somewhere but not printing it. Am I looking at wrong place?

NOTE: Picked up JDK_JAVA_OPTIONS:  --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMEDPicked up 
JAVA_TOOL_OPTIONS: -Xmx4878M -Djava.net.preferIPv4Stack=true -javaagent:/agents/java/applicationinsights-agent-codeless.jar 

• Also, if I set, I need to make sure the default things (like javaagent) does not get overriten otherwise I would lose out other default necessary things (like app insights)

Apparently just put JAVA_OPTS -Xmx10G and you are done, it does not override the original variables.
