将默认Java VM更改为Client [英] Change Default Java VM to Client

问题描述

我在Fedora 17上安装了Oracle的Java，我注意到当使用命令java -version时，它会返回

I installed Oracle's Java on Fedora 17, and I noticed that when using the command java -version it returns this

java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

Java似乎默认运行-server选项.帮助文字显示为

Java seems to run the -server option by default. The help text came up as

-server   to select the "server" VM
              The default VM is server,
              because you are running on a server-class machine.

有什么办法可以将默认值更改为客户端?

Is there any way to change the default to client?

推荐答案

默认设置在文件 jvm.cfg 中定义.像

The default setting is defined in the file jvm.cfg. A content like

-client KNOWN
-server KNOWN

将客户端定义为默认客户端.

defines the client as the default.

-server KNOWN
-client KNOWN

将服务器设置为默认服务器.

sets the server as the default.

未安装JDK的Mac OS X版本10.9:

Mac OS X version 10.9 without installing JDK:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/jvm.cfg

已安装JDK版本1.8.0_u92的Mac OS X版本10.9:

^{您可以使用命令$ locate /jvm.cfg从命令行(Terminal.app)中找到jvm.cfg.您可能需要先使用以下命令更新定位数据库:$ sudo /usr/libexec/locate.updatedb}

^{You can find your jvm.cfg from the command line (Terminal.app) using the command $ locate /jvm.cfg. You might need to update your locate database first, using the command: $ sudo /usr/libexec/locate.updatedb}
