如何设置从控制台运行Java的亲和力

Question

Since I dont have hyper threading option in the BIOS I am gonna disable it by launching

start /affinity 01010101

like here

The problem is that I would like to run a java program with that option but I cant make it

C:\Users\gbarbieri>start /affinity 01010101 "C:\Program Files\Java\jdk1.7.0_71\j
re\bin\java.exe" -jar D:\Documents\NetBeansProjects\EC_400_BETA\dist\EC_400_BETA
.jar
Die Datei "-jar" kann nicht gefunden werden.(= -jar cannot be found)

I tried include -jar in the '' , include also the .jar, but nothing..

So how do I set affinity running a jar from console?

Answer 1

This should be marked as a duplicate of Using the "start" command with parameters passed to the started program . However, I only found out that there was a another question with the right solution after finding out why the OP's command line didn't work.

The problem is that the Windows start command treats the first argument in double quotes specially. It treats it as the title to display in the command prompt window. (See the Microsoft documentation )

The work around is to provide a title explicitly before providing a command name that needs double quotes (such as any command inside c:\\Program Files\\ because of the space in that path name)

This could just be an empty title, like this:

C:\Users\gbarbieri>start "" /affinity 01010101 "C:\Program Files\Java\jdk1.7.0_71\j
re\bin\java.exe" -jar D:\Documents\NetBeansProjects\EC_400_BETA\dist\EC_400_BETA
.jar
