win10 8g内存 该如何分配内存

java -XX:MaxPermSize=128m -Xms128m -Xmx3G

这是目前的

java -Xmx4096M -Xms1024M -核心jar名字

Invalid maximum heap size: -Xmx4096M
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

java用的是32位的吧，32位的java最大只能使用1G（也就是1024M）内存，请更换64位java

内存调到1024 后显示Cannot run server in a directory with ! or + in the pathname. Please rename the affected folders and try again.
