增加堆大小后无法启动 Glassfish
我想增加 Glassfish 的堆大小。为此，我知道我最多可以达到 4GB：
java -Xmx4000M -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
我尝试在 domain.xml 文件中将 -Xmx 设置为 2GB：
<jvm-options>-Xmx2000m</jvm-options>
但我收到以下错误：
asadmin> start-domain
Waiting for ... to start .Error starting domain ...
The server exited prematurely with exit code 1.
Before it died, it produced the following output:
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size
launchctl bsexec failed: Inappropriate ioctl for device
使用 -v 选项启动命令会出现以下错误：

I want to increase the heap size of my Glassfish. For that, I know that I can go up to 4GB:
java -Xmx4000M -version
java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03-384-10M3425)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02-384, mixed mode)
I tried to set in domain.xml file the -Xmx to 2GB:
<jvm-options>-Xmx2000m</jvm-options>
But I am getting the following error:
asadmin> start-domain
Waiting for ... to start .Error starting domain ...
The server exited prematurely with exit code 1.
Before it died, it produced the following output:
Error occurred during initialization of VM
The size of the object heap + VM data exceeds the maximum representable size
launchctl bsexec failed: Inappropriate ioctl for device
Launching the command with -v option gives this:
12 oct. 2011 11:46:34 com.sun.enterprise.admin.launcher.GFLauncherLogger info
INFO: JVM invocation command line:

我发现了问题。由于某些我不明白的原因，命令中传递了“-d32”参数，要求以 32 位模式启动。 时
添加到domain.xml 文件 ，glassfish 启动。请注意，文件中默认不存在此选项。
I found the problem. For some reasons which I do not understand, the "-d32" argument was passed in the command, asking to start in 32 bits mode. When adding
to the domain.xml file, glassfish starts. Please note that this option is not present by default in the file.
在执行“-version”时，您必须在 GlassFish 中使用不同的 Java 安装。我可以使用 Mac OS 路径中的默认“java”重现相同的错误，但在使用绝对路径时不能重现：
you must be using a different Java install when doing the "-version" and from within GlassFish. I can reproduce the same error with the default "java" in Mac OS' path but not when using an absolute path :
可能是您的系统上没有足够的磁盘空间？保留 4GB RAM 可能需要 MAC OS 扩展交换空间，而您可能没有足够的磁盘空间来执行此操作。不幸的是，这之前已经烧伤过我了:-/
Could it be that you don't have enough disk space on your system? Reserving 4GB of RAM may require MAC OS to expand swap space, and you may not have the disk space to do this. Unfortunately, this has burned me before :-/
