I have mentioned the configuration changes needed for the increase of heap size in Linux environments.

Go to the following location and edit the following file.

bin/standalone.conf

Search for the following line, 

JAVA_OPTS

and change it accordingly to suit your heap size needs

-Xms1303m: initial heap size in megabytes
-Xmx1303m: maximum heap size in megabytes

JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"

Finally after saving the work, restart the server.

1) Go to $JBOSS_HOME/bin/standalone.conf(or if you are running different than that name)

2) Go to the line where it says "JAVA_OPTS="-Xms256m -Xmx1024m -XX:MaxPermSize=256m....."

3) Edit that line to your requirements.

The configuration for standalone is in the configuration file: bin/appclient.conf.bat

set "JAVA_OPTS=-Xms64M -Xmx1024M -XX:MaxPermSize=512M"

There are several ways to configure JVM options in domain mode.

1 - configuration for all server of a server group

   <server-group name="main" profile="full"> 
    <jvm name="default">
    <heap size="256m" max-size="512m"/>
       <permgen max-size="256m"/>
    </jvm>
    ...
    </server-group>

`

2 - common configuration for all server of a host

<jvms>
  <jvm name="default">
    <heap size="64m" max-size="256m"/>
    <permgen size="256m" max-size="256m"/>
    <jvm-options>
      <option value="-server"/>
     </jvm-options>
    </jvm>
</jvms>

3 - override common configuration of one server

<server name="server1" group="main“> 
  <jvm name="default">
    <heap size="64m" max-size="256m"/>
  </jvm>
  ...
</server>
