Derby 客户端 jdbc 驱动程序连接错误：无法创建数据库“示例”

【问题标题】：Derby client jdbc driver connection error : Failed to create database 'sample'Derby 客户端 jdbc 驱动程序连接错误：无法创建数据库“示例”
【发布时间】：2016-01-10 21:09:13
【问题描述】：

我按照本教程中的说明启动了 Derby 网络服务器 - here。

但是当我输入时：

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

我收到以下错误：

ERROR XJ041: DERBY SQL 错误: ERRORCODE: 40000, SQLSTATE: XJ041, SQLERRMC: d 创建数据库 'sample' 失败，请参阅下一个异常 详情::SQLSTATE: XB M0H

任何想法如何解决这个问题？

【问题讨论】：

  • 您能找到您的 Derby 网络服务器创建的“derby.log”文件吗？查看该日志，您将找到 Derby Network Server 在尝试创建数据库时遇到的完整异常。在此处将该日志输出复制到您的问题中。
  • 我观察到了同样的问题。另一个观察结果是，该数据库首先在 Mac 设备上创建，然后在显示上述错误消息的 Windows 设备上查看。数据库版本与驱动不兼容。
  • 其实我通过安装Derby 10.14版本解决了上述问题。

标签： java jdbc connection client-server derby


【解决方案1】：

使用 Derby 时请注意替代驱动器 - 如果将数据库放在替代驱动器上，它将无法工作，并且您会在日志中遇到令人困惑的 nio 异常和类转换错误。所以这不工作：

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

其中 t 被替换。指向驱动器 c 的相同命令确实有效：

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

在 Derby 网站上有关于这些问题的讨论，但可能不是针对所有情况都解决了？包括数据库本身在替代驱动器上的位置。我目前使用的是 10.10.2.0 版本

    【解决方案2】：

    从您的异常堆栈跟踪来看，您的 Derby 网络服务器进程似乎是在文件夹 C:\Program Files\Java\jdk1.8.0_45\db\bin\ 中启动的，并且该进程似乎没有在该文件夹中写入（Derby 数据库）文件的权限。尝试查找 Derby 服务器进程有权将文件写入其中的文件夹。您可以在 Derby 连接 URL 中指定 Windows 驱动器号和路径。只需确保将任何反斜杠 \ 转换为正斜杠 / 或像这样 \\ 转义它们。因此，例如，如果您知道 Derby 服务器进程可以写入 d:\temp 文件夹，那么您可以将命令编写为

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

    或

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

      【解决方案3】：

      日志条目状态：

      无法创建目录C:\Program Files\Java\jdk1.8.0_45\db\bin\sample

      据我所知，这可能是network server 进程没有足够的权限在C:\Program Files\Java\jdk1.8.0_45\db\bin\ 中创建目录的一些权限问题。您可以尝试以管理员身份运行它。
