无法通过Pentaho连接到oracle。'oracle.jdbc.driver.OracleDriver' 找不到

java oracle11g jdbc oracle pentaho

2022-09-03 09:22:12

嗨，我刚刚安装了Pentaho Data Integration v. 5.01，我正在尝试连接到数据库。但是，我无法测试连接，因为我收到错误（粘贴在下面）。

我在系统上也安装了JDK 1.7，但是我似乎无法在任何地方找到ojdbc14.jar。

我下载了它并将其粘贴到pentaho的\lib文件夹中，但我仍然得到同样的错误。

这个问题有什么解决方案吗？

答案 1

尝试将 odbc jar 文件（例如：ojdbc5-11.1.0.7.0.jar）放在安装的“data-integration/lib”目录中。不要忘记重新启动Pentaho以使其正常工作。

答案 2

这是我的设置。我遇到了这个问题，并设法按如下方式修复了它。

我在我的机器上运行SQLDeveloper，即使在VPN下也可以正常工作。但是，我正在运行Spoon，并注意到如果我使用VPN，它将不起作用。

我试图将SQLDeveloper附带的Oracle JDBC驱动程序放入Pentaho中。这不起作用。

但是，我注意到SQLDeveloper和Spoon之间的一大区别是它们使用不同的Java运行时和JDBC Oracle驱动程序！特别是，我的 SQLDeveloper 版本在 32 位 JRE 版本 1.6.0_11 上运行，而我的系统范围的 JDK 是 64 位版本 1.7.0_03。

我找到了 SQLDeveloper 使用的 JDBC 驱动程序，并将它们用作 Spoon 附带的驱动程序的替代品 - 没有更改。

然后，我重新定位了Spoon以使用SQLDeveloper使用的Java运行时。

我设置了两个环境变量：PENTAHO_JAVA和PENTAHO_JAVA_HOME - 现在工作正常！

作为参考，这是我的羡慕：

PENTAHO_JAVA=C:\opt\sqldeveloper\jdk\jre\bin\java.exe
PENTAHO_JAVA_HOME=c:\opt\sqldeveloper\jdk\jre\

如果这相关，我在Windows 7 x64上。
