在windows環境下設定Derby變量

1. 首先需要設定java_home，至于設定方法已經很多了。一般來說，隻要安裝了Java虛拟機，就能自動設定。可以通過Java

-version來檢視目前Java的版本。如果能看到目前的版本好，則說明設定是成功的。

1. C:/Documents and Settings/YUCHENGHU>java -version
2. java version "1.6.0_11"
3. Java(TM) SE Runtime Environment (build 1.6.0_11-b03)
4. Java HotSpot(TM) Client VM (build 11.0-b16, mixed mode, sharing)
5. C:/Documents and Settings/YUCHENGHU>

2.

設定DERBY_HOME環境變量，同時需要将%DERBY_HOME%/bin添加到PATH變量中。

如果輸入sysinfo.bat後，提示輸入了不可識别的指令，則說明這一步沒有設定正确，可以在系統

變量中檢測。

1. C:/Documents and Settings/YUCHENGHU>sysinfo.bat
2. 'sysinfo.bat' is not recognized as an internal or external command,
3. operable program or batch file.

可以輸入指令echo %DERBY_HOME%來校驗是否正确的設定了DERBY_HOME變量，如果能正确輸出Derby

所在的路徑，則說明已經正确的設定了DERBY_HOME變量，否則沒有目錄輸出。

1. C:/Documents and Settings/YUCHENGHU>echo %DERBY_HOME%
2. %DERBY_HOME%

下圖是未設定DERBY_HOME變量的輸出

添加DERBY_HOME變量

同時還需要在系統的PATH變量中添加：%DERBY_HOME%/bin;

當你完成上述步驟後，重新打開一個控制台，輸入echo

%DERBY_HOME%應該就可以Derby所在目錄的輸出了

2. D:/Dkits/derby

這時候可以輸入sysinfo指令來檢視Derby資料庫

的基本資訊。

1. C:/Documents and Settings/YUCHENGHU>sysinfo
