Derby客戶機jdbc驅動程序連接錯誤：無法創建數據庫'樣本'

Question

我開始使用Derby Network Server，如本教程中所述 - here。

但是，當我輸入：

ij> connect 'jdbc:derby://localhost:1527/sample;create=true', 

我得到以下錯誤：

ERROR XJ041: DERBY SQL error: ERRORCODE: 40000, SQLSTATE: XJ041, SQLERRMC: Faile d to create database 'sample', see the next exception for details.::SQLSTATE: XB M0H

任何想法如何解決這一問題？

Answer 1

日誌條目狀態：

Directory C:\Program Files\Java\jdk1.8.0_45\db\bin\sample cannot be created

所以據我知道這可能是一些權限問題與network server過程不必在創建一個目錄足夠的權限C:\Program Files\Java\jdk1.8.0_45\db\bin\。您可以嘗試以管理員身份運行它。

Answer 2

從您的異常堆棧跟蹤看起來，您的Derby網絡服務器進程在文件夾C:\Program Files\Java\jdk1.8.0_45\db\bin\中啓動，並且該進程似乎沒有在該文件夾中寫入（Derby數據庫）文件的權限。嘗試找到Derby服務器進程有權將文件寫入的文件夾。您可以在Derby連接URL中指定Windows驅動器號和路徑。只要確保將任何反斜槓\轉換爲正斜槓/或者像這樣轉義它們\\。所以，如果，例如，如果你知道德比服務器進程可以寫入到d：\ temp文件夾，那麼你可以撰寫你的命令

ij> connect jdbc:derby://localhost:1527/d:/temp/sample;create=true

或

ij> connect jdbc:derby://localhost:1527/d:\\temp\\sample;create=true

Answer 3

謹防取代驅動器時使用Derby - 如果將數據庫放在替代驅動器上，它將無法工作，並且會在日誌中混淆nio異常和類轉換錯誤。因此這並沒有工作：

connect 'jdbc:derby://localhost:1527/t:/DerbyDB;create=true'; 

其中T是取代。在驅動器C指出同樣的命令做的工作：

connect 'jdbc:derby://localhost:1527/c:/DerbyDB;create=true'; 

還有就是在德比現場，這些問題的討論 - 但也許它不是固定的所有情況？包括數據庫本身在替代驅動器上的位置。我目前正在使用版本10.10.2.0
