    Description

      • If the "host.xml" has the following JVM name defined
          <jvms>
              <jvm name="default">
                  <heap size="200m" max-size="2000m"/>
                  <permgen size="256m" max-size="256m"/>
                  <jvm-options>
                      <option value="-server"/>
                  </jvm-options>
              </jvm>
              <jvm name="Test">
                  <heap size="300m" max-size="2500m"/>
                  <permgen size="128m" max-size="128m"/>
              </jvm>
          </jvms>
      
      • If the server refers to the above JVM name as following:
          <servers>
              <server name="server-one" group="main-server-group" auto-start="true">
              <jvm name="Test"/>
              </server>
          </servers>
      
      • In above case when the server-one is booted that time it takes the value from "server-group" (in this case main-server-group) defined in the domain.xml
          <server-groups>
              <server-group name="main-server-group" profile="full">
                  <jvm name="default">
                      <heap size="64m" max-size="512m"/>
                  </jvm>
      

      So the JVM settings defined for JVM name "Test" is overridden by server-group values:

      30201 jboss-modules.jar -agentpath:/usr/lib64/libabrt-java-connector.so=abrt=on -D[Server:server-one] -XX:PermSize=128m -XX:MaxPermSize=128m -Xms64m -Xmx512m -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Djboss.home.dir=/wildfly-9.0.0.CR1-SNAPSHOT -Djboss.modules.system.pkgs=org.jboss.byteman -Djboss.server.log.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/log -Djboss.server.temp.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/tmp -Djboss.server.data.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/data -Dlogging.configuration=file:/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/data/logging.properties
      

      NOTICE the JVM runtime value is -Xms64m -Xmx512m, where as it was supposed to be -Xms300m -Xmx2500m as that is the "Test" jvm setting.
