Jboss-eap-6.3 Could not reserve enough space for object heap
提问by java developer
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 Windows 上运行 Java7。
当我运行 Jboss-eap-6.3 服务器时，每次尝试运行该程序时都会重复出现以下异常。

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 gensetting from the JAVA_OPTSline:
其实是启动脚本的问题。这是https://bugzilla.redhat.com/show_bug.cgi?id=956281的错误。解决方法是从行中删除perm gen设置JAVA_OPTS：
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

What is the memory available with your machine?
I see the parameters -Xms1G -Xmx1G. This means that your JVM will be started with Xms=1GBamount of memory and will be able to use a maximum of Xmx=1GBamount of memory.
您的机器有多少可用内存？我看到了参数-Xms1G -Xmx1G。这意味着您的 JVM 将以Xms=1GB大量内存启动，并且将能够使用最Xmx=1GB大量的内存。
I think, may be you reduce the amount of memory (like -Xmx2048m -Xms256m).
我想，可能是你减少了内存量（比如-Xmx2048m -Xms256m）。
I hope it helps.
我希望它有帮助。
You can refer to this.

According to the above Federico Sierra answer under
jboss-eap-6.3\domain\configurationlocation host.xmlfile is present. In that file I just commented the following line:
根据上面的 Federico Sierra 答案，
jboss-eap-6.3\domain\configuration位置host.xml文件下存在。在该文件中，我刚刚评论了以下行：
<permgen size="256m" max-size="256m"/>
It's working. Thanks Federico Sierra.
它正在工作。感谢费德里科·塞拉。

You can also resolve this by changing JAVA_OPTS value under standalone.conf.bat.
您也可以通过更改 standalone.conf.bat 下的 JAVA_OPTS 值来解决这个问题。
old
老的
rem # JVM memory allocation pool parameters - modify as appropriate.
set "JAVA_OPTS=-Xms1303M -Xmx1303M -XX:MaxPermSize=256M"
new
新的
set "JAVA_OPTS=-Xms256M -Xmx256M -XX:MaxPermSize=256M"

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
如果尝试上述所有选项后仍然不起作用。转到：jboss-eap-6.4\domain\configuration -> host.xml，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
并转到：jboss-eap-6.4\standalone\configuration -> standalone.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.
现在重新启动您的 Eclipse 并尝试运行您的 Jboss6.1+ 服务器，它应该可以正常工作。
Also set this in host.xml: <permgen size="256m" max-size="256m"/>Good Luck.
也将其设置为host.xml: <permgen size="256m" max-size="256m"/>“好运”。
