How to increase heap memory for WildFly?
提问by Manuela
WildFly 8 is started on a linux server with standalone.sh. I noticed that the server was started with very few heap memory space.
WildFly 8 在带有 standalone.sh 的 Linux 服务器上启动。我注意到服务器启动时堆内存空间很少。
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?
我需要为服务器和在服务器上运行的应用程序增加堆内存空间。我该怎么做？

Just edit bin/standalone.conf, look for the first occurrence of JAVA_OPTSand change the -Xmxoption according to your needs.
只需编辑bin/standalone.conf，查找第一次出现JAVA_OPTS并-Xmx根据您的需要更改选项。

For managed domain you can set it using heaptag (e.g.<heap size="64m" max-size="512m"/>) within jvmin domain.xml or host.xml (depending on the scope you want to address).
对于托管域，您可以使用domain.xml 或 host.xml 中的heap标记（例如<heap size="64m" max-size="512m"/>）进行jvm设置（取决于您要寻址的范围）。

if wildfly 8 is used along with JDK 8, We need to add MaxMetaSpace Size. For example, JAVA_OPTS="$JAVA_OPTS -XX:MaxMetaspaceSize=256M" As we all know Java 8 does not support Perm gen setting. For related information, Please check Wildfly Heap issue
如果wildfly 8与JDK 8一起使用，我们需要添加MaxMetaSpace Size。例如 JAVA_OPTS="$JAVA_OPTS -XX:MaxMetaspaceSize=256M" 众所周知，Java 8 不支持 Perm gen 设置。有关相关信息，请查看 Wildfly Heap 问题
I hope it helps.

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 http://www.nailedtothex.org/roller/kyle/entry/articles-wildfly-jvmparams
我正在运行 Eclipse 并且更改“bin/standalone.conf”对我不起作用。在这种情况下，解决方案是在 Eclipse 中打开“服务器”视图，双击 Wildfly 服务器，转到“打开启动配置”并在“VM 参数”中进行更改。无论如何，我对 Wildfly 有点菜鸟，我希望其他用户可以对比我的信息，我在http://www.nailedtothex.org/roller/kyle/entry/articles-wildfly-jvmparams 中找到了
Its for a Linux server, but I think it could work for windows too.
它适用于 Linux 服务器，但我认为它也适用于 Windows。

Answer from official documentation:
来自官方文档的回答：
For a standalone server, you have to pass in the JVM settings either as command line arguments when executing the
$JBOSS_HOME/bin/standalone.shscript, or by declaring them in$JBOSS_HOME/bin/standalone.conf. (For Windows users, the script to execute is%JBOSS_HOME%/bin/standalone.batwhile the JVM settings can be declared in%JBOSS_HOME%/bin/standalone.conf.bat)
对于独立服务器，您必须在执行
$JBOSS_HOME/bin/standalone.sh脚本时将 JVM 设置作为命令行参数传递 ，或者通过在$JBOSS_HOME/bin/standalone.conf. （对于 Windows 用户，要执行的脚本是%JBOSS_HOME%/bin/standalone.bat可以在 中声明 JVM 设置的%JBOSS_HOME%/bin/standalone.conf.bat）
** Restart server to make this change effective.
** 重新启动服务器以使此更改生效。

Linux:
Linux：
bin/standalone.conf
Check for the following line,
检查以下行，
JAVA_OPTS
and change it accordingly to suit your heap size needs
并相应地更改它以满足您的堆大小需求
-Xms1303m: initial heap size in megabytes
-Xmx1303m: maximum heap size in megabytes
JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
Windows:
窗户：
bin/standalone.conf.bat
JAVA_OPTS="-Xms1024M -Xmx2048M -XX:MaxPermSize=2048M -XX:MaxHeapSize=2048M"
Now restartthe server and it will work without prompting any heap size errors.
现在重新启动服务器，它将在不提示任何堆大小错误的情况下工作。
