Jmeter啟動GUI界面出錯

今天要用Jmeter測試伺服器性能，發現GUI界面總是有warning提示：

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

在網上搜了搜，發現是Jmeter需要寫系統資料庫。

解決辦法如下

Problem(Abstract)

After running a clemb command under Windows 7 with Modeler 14.1 the following error is produced:

java.util.prefs.WindowsPreferences <init> 

WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs 

at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Cause

The error occurs because java.util.prefs.WindowsPreferences is trying to save information in HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs instead of under HKEY_CURRENT_USER\Software\JavaSoft\Prefs.

java.util.prefs.WindowsPreferences需要儲存資訊到HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs而不是HKEY_CURRENT_USER\Software\JavaSoft\Prefs。

Environment

Windows 7 64-bit

Resolving the problem

The work around is to login as the administrator and create the key HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs.
