jsp -eap-6.3不能为对象堆预留足够的空间

I have Java7 running on 32-bit Windows.
When I am running Jboss-eap-6.3 server, I am getting the following exception repeatedly each time I try to run the program.

我在32位的Windows上运行Java7。当我运行Jboss-eap-6.3服务器时，每次尝试运行程序时，我都会重复地得到以下异常。

It's actually a problem with the startup script. Here's the bug for that https://bugzilla.redhat.com/show_bug.cgi?id=956281. The workaround is to remove the perm gen setting from the JAVA_OPTS line:

这实际上是启动脚本的问题。这里是https://bugzilla.redhat.com/show_bug.cgi?id=956281的bug。解决方法是将perm gen设置从JAVA_OPTS行中删除:

Cause: The max perm gen space parameter is causing the JVM to not be created, which then prevents the server from starting.  This is specifically on Windows 8 32-bit JVM.
Consequence: The server will not start.
Workaround (if any): Remove the -XX:MaxPermSize=256m

You can also resolve this by changing JAVA_OPTS value under standalone.conf.bat.

您还可以通过在standalone.conf.bat下更改JAVA_OPTS值来解决这个问题。

rem # JVM memory allocation pool parameters - modify as appropriate.
set "JAVA_OPTS=-Xms1303M -Xmx1303M -XX:MaxPermSize=256M"

set "JAVA_OPTS=-Xms256M -Xmx256M -XX:MaxPermSize=256M"

What is the memory available with your machine? I see the parameters -Xms1G -Xmx1G. This means that your JVM will be started with Xms=1GB amount of memory and will be able to use a maximum of Xmx=1GB amount of memory.

你的机器可用的内存是多少?我看到参数-Xms1G -Xmx1G。这意味着JVM将从Xms=1GB的内存开始，并且可以使用最大的Xmx=1GB的内存。

I think, may be you reduce the amount of memory (like -Xmx2048m -Xms256m).

我认为，可能是您减少了内存的数量(比如-Xmx2048m -Xms256m)。

I hope it helps.

我希望它有帮助。

According to the above Federico Sierra answer under jboss-eap-6.3\domain\configuration location host.xml file is present. In that file I just commented the following line:

根据以上在jboss-eap-6.3\domain\配置位置主机下的Federico Sierra答案。xml文件。在这个文件中，我只评论了下面一行:

<permgen size="256m" max-size="256m"/>

It's working. Thanks Federico Sierra.

这是工作。谢谢费德里科•塞拉。

If it still doesn't work after trying all above options. Go To: jboss-eap-6.4\domain\configuration -> host.xml, and have this size set up

如果在尝试了以上所有的选项后仍然不能工作。转到:jboss-eap-6.4\domain\configuration ->主机。并设置这个大小

<heap size="256m" max-size="256m"/>

And also go to: jboss-eap-6.4\standalone\configuration -> standalone.xml, have this size set up

也可以转到:jboss-eap-6.4\独立的\配置->。xml，设置这个大小。

set "JAVA_OPTS=-Xms256M -Xmx256M -XX:MaxPermSize=256M"

And now Restart your Eclipse and try Run your Jboss6.1+ server it should be working.

现在重新启动Eclipse，并尝试运行Jboss6.1+服务器。

Also set this in host.xml: <permgen size="256m" max-size="256m"/> Good Luck.

还要在主机中设置这个。xml: 好运。
