Just edit <code>bin/standalone.conf</code>, look for the first occurrence of <code>JAVA_OPTS</code> and change the <code>-Xmx</code> option according to your needs.

For managed domain you can set it using <code>heap</code> tag (e.g.<code>&lt;heap size="64m" max-size="512m"/&gt;</code>) within <code>jvm</code> in domain.xml or host.xml (depending on the scope you want to address).

if wildfly 8 is used along with JDK 8,
We need to add MaxMetaSpace Size.
For example,
JAVA_OPTS="$JAVA_OPTS -XX:MaxMetaspaceSize=256M"
As we all know Java 8 does not support Perm gen setting.

I am running Eclipse and changing the 'bin/standalone.conf' didn’t work for me. In this case the solution was oppening the 'Servers' view in Eclipse, double-click the Wildfly server, go to 'Open launch configuation' and do that changes there in 'VM argumments'. Anyway I am a bit noob with Wildfly, I hope other users could contrast my info, I found that in <a href="http://www.nailedtothex.org/roller/kyle/entry/articles-wildfly-jvmparams" rel="noreferrer">http://www.nailedtothex.org/roller/kyle/entry/articles-wildfly-jvmparams</a>

Its for a Linux server, but I think it could work for windows too.

Answer from <a href="https://docs.jboss.org/author/display/WFLY10/JVM+settings" rel="nofollow noreferrer">official documentation</a>:

<blockquote>
 For a standalone server, you have to pass in the JVM settings either
 as command line arguments when executing the
 <code>$JBOSS_HOME/bin/standalone.sh</code> script, or by declaring them in
 <code>$JBOSS_HOME/bin/standalone.conf</code>. (For Windows users, the script to
 execute is <code>%JBOSS_HOME%/bin/standalone.bat</code> while the JVM settings can
 be declared in <code>%JBOSS_HOME%/bin/standalone.conf.bat</code>)
</blockquote>

** Restart server to make this change effective.

Linux:

<pre><code>bin/standalone.conf
</code></pre>

Check for the following line, 

<pre><code>JAVA_OPTS
</code></pre>

and change it accordingly to suit your heap size needs

<pre><code>-Xms1303m: initial heap size in megabytes
-Xmx1303m: maximum heap size in megabytes

JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
</code></pre>

Windows:

<pre><code>bin/standalone.conf.bat

JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
</code></pre>

Now restart the server and it will work without prompting any heap size errors.

WildFly 8 is started on a linux server with standalone.sh. I noticed that the server was started with very few heap memory space. 

I need to increase the heap memory space for the server and for applications, which are running on the server. How can I do it?

WildFly 8是在带有standalone.sh的linux服务器上启动的。我注意到服务器启动时只有很少的堆内存空间。我需要为服务器和运行在服务器上的应用程序增加堆内存空间。我该怎么做呢？
