Question

我尝试在Windows上打开软件Cyc（可在此处获取：https://sourceforge.net/projects/opencyc/files/OpenCyc%204.0/）。

我按照说明执行BAT文件“run-cyc”启动，然后我在cmd.exe上显示此消息：

PORT OFFSET = 00
Invalid initial heap size: -Xms5g
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
...

我知道我必须使用像“java -Xms200m”这样的命令来改变大小（哪个大小最好？）但我不知道该写些什么。

以下是BAT文件的脚本：

rem run-cyc.bat
rem
rem
rem Assumes that java 1.5 or higher (1.6 or higher preferably) is in your path

set DEFAULT_PORT_OFFSET=00

rem AN INVALID PORT WAS SPECIFIED

:set_port
SET PORT_OFFSET=%1

:port_set
echo PORT_OFFSET = %PORT_OFFSET%

set INIT_FORM="(progn (load \"init/jrtl-release-init.lisp\") (cinc *base-tcp-port* %PORT_OFFSET%) (load \"init/port-init.lisp\"))"

rem Add the following line to the JVM options to allow remote debugging

if not defined BACKGROUND pause

那么你能告诉我如何改变大小，在哪里？使用cmd.exe中的命令或BAT文件内的命令？

谢谢

Answer 1

删除对您的计算机来说太大的-Xms5g，并从小处开始，也许您提到的-Xms200m将是一个不错的起点。

初始堆大小无效：-Xms5g
