解决方法：“ VM初始化期间发生错误； 无法为对象堆保留足够的空间”
[英]How to resolve this : “Error occurred during initialization of VM; Could not reserve enough space for object heap”
问题描述
I am trying to start my database server from command prompt in Windows. 
我正在尝试从Windows中的命令提示符启动数据库服务器。 But I receive the following error: 但是我收到以下错误：
Error occurred during initialization of VM
Could not reserve enough space for object heap
However the attempt is successful if I log off and log on again or restart. 但是，如果我注销并再次登录或重新启动，则尝试成功。 I think it is because of insufficient RAM in my computer (1GB). 我认为这是由于计算机中的内存不足（1GB）。
How can I resolve this issue? 我该如何解决这个问题？
Please retag if I have tagged it wrong. 如果我标记错了，请重新标记。 Thanks! 谢谢！

Try changing the memory settings of the VM. 尝试更改VM的内存设置。 see here how to pass this as command-line arguments. 请参阅此处如何将其作为命令行参数传递。 For example 例如
java -Xmx512m -Xms256m ....
If, however, your machines does not have enough RAM to handle this, the only resolution is to buy more RAM. 但是，如果您的计算机没有足够的RAM来处理此问题，则唯一的解决方法是购买更多RAM。 It might still be possible to make it run with tweaking the above settings - I once spent half an hour trying to run an application with a limited amount of RAM by experimenting with different values for Xmx and MaxPermSize . 通过调整上面的设置，仍然可以使它运行-我曾经花半个小时尝试通过对Xmx和MaxPermSize不同值进行试验来运行内存有限的应用程序。

I got the same error and resolved it by changing values in grade settings file of project 我遇到了相同的错误，并通过更改项目的成绩设置文件中的值解决了该问题
org.gradle.jvmargs=-Xmx1536m to org.gradle.jvmargs=-Xmx512m org.gradle.jvmargs = -Xmx1536m到org.gradle.jvmargs = -Xmx512m

Try giving the JVM an extra argument: 尝试给JVM一个额外的参数：
-mX256M
Despite the gigabyte of RAM in your machine, Java is only given a small chunk (64mb?) to play with. 尽管您的计算机中有GB的RAM，但Java只能使用一小块（64mb？）来使用。 This argument allocates even more memory to the process. 此参数为进程分配更多的内存。
