Retain Java settings on Linux

Hi All,

 I have a Linux(SLE 12) that is running retain 4.8 and I want to make sure JAVA is using the most RAM, I think our settings were edited at one time but I do not see in my notes how I did this.

This server has 24 gb of RAM and I wonder if our settings for Xms and Xmx should be the same?

retainSERVER:~ # ps -up 1870
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
tomcat 1870 11.7 93.7 225283724 23925268 ? Ssl 06:00 34:48 /opt/beginfinite/retain/java/jdk-11+28/bin/java -Djava.library.path=/opt/beginfinite/retain/RetainServer/WEB-INF/bin -Djava.awt.headless=true -XX:+CMSClassUnloadingEnabled -Xverify:none -XX:-CreateMinidumpOnCrash -XX:MaxMetaspaceSize=1024m -XX:-UseGCOverheadLimit -XX:+UseG1GC -Xms4g -Xmx16g -Xss1024k -classpath /opt/beginfinite/retain/tomcat/bin/bootstrap.jar:/opt/beginfinite/retain/tomcat/bin/tomcat-juli.jar

Thanks,

Joe
