My system is on a server that has several Tomcats, I need to disable the Tomcat that has more memory reserved for it.

How I see the memory reserved for each Tomcat on the server?

java server tomcat server-side

The Memory Heap used by Tomcat is defined by the parameter jvm -Xmx.

Check if the environment variable exists 

CATALINA_OPTS=-Xms64m -Xmx256m

Check if the above variable is used by the following script: Also check the parameter JAVA_OPTS -Xmx1024m in the scripts below

tomcat-install/bin/catalina.sh(.bat) 
tomcat-install/bin/startup.sh(.bat)

A simpler way is to simply run the command, but only under linux

ps -ef | grep java

and search for the Tomcat instance by checking the parameters Xms and Xmx

  • This ps -Ef | grep java command I can run on the server CMD?

  • Yes as long as it’s linux

  • Unfortunately it is windows, the company let install in this blessing.

  • I edited the answer, as it is windows you need to look at the files . bat of the installation to see the memory allocated to the server
