Question

首先，我是WLS的新手。我从昨天起就一直在寻找这个问题，但找不到解决办法。我收到了这个错误：

C:\Oracle\MIDDLE~1\JDK160~1\bin\java -client   -Xms512m -Xmx1024m -XX:CompileThreshold=8000 -XX:PermSize=512m -XX:MaxPermSize=1024m -Dweblogic.Name=DefaultServer - ....
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

我在setDomainEnv.cmd（我在Windows 7 64位上）设置了JVM选项，如下所示：

@REM IF USER_MEM_ARGS the environment variable is set, use it to override ALL MEM_ARGS values
set USER_MEM_ARGS=-Xms512m -Xmx1024m -XX:CompileThreshold=8000 -XX:PermSize=512m -XX:MaxPermSize=1024m

if NOT "%USER_MEM_ARGS%"=="" (
    set MEM_ARGS=%USER_MEM_ARGS%
)

I also changed these values:

set XMS_SUN_64BIT=512
set XMS_SUN_32BIT=512
set XMX_SUN_64BIT=1024
set XMX_SUN_32BIT=1024
set XMS_JROCKIT_64BIT=512
set XMS_JROCKIT_32BIT=512
set XMX_JROCKIT_64BIT=1024
set XMX_JROCKIT_32BIT=1024


if "%JAVA_VENDOR%"=="Sun" (
    set WLS_MEM_ARGS_64BIT=-Xms512m -Xmx1024m
    set WLS_MEM_ARGS_32BIT=-Xms512m -Xmx1024m
) else (
    set WLS_MEM_ARGS_64BIT=-Xms512m -Xmx1024m
    set WLS_MEM_ARGS_32BIT=-Xms512m -Xmx1024m
)

if "%JAVA_VENDOR%"=="Oracle" (
    set CUSTOM_MEM_ARGS_64BIT=-Xms%XMS_JROCKIT_64BIT%m -Xmx%XMX_JROCKIT_64BIT%m
    set CUSTOM_MEM_ARGS_32BIT=-Xms%XMS_JROCKIT_32BIT%m -Xmx%XMX_JROCKIT_32BIT%m
) else (
    set CUSTOM_MEM_ARGS_64BIT=-Xms%XMS_SUN_64BIT%m -Xmx%XMX_SUN_64BIT%m
    set CUSTOM_MEM_ARGS_32BIT=-Xms%XMS_SUN_32BIT%m -Xmx%XMX_SUN_32BIT%m
)

但他们没有改变结果。上述配置有什么问题？

Answer 1

问题是MAVEN_OPTS环境变量。它是： MAVEN_OPTS = -Xmx512m -XX：MaxPermSize = 1024m 我改成了： -Xms512m -Xmx1024m --XX：PermSize = 512m -XX：MaxPermSize = 1024m
