【问题描述】：

我目前在 Pentaho Spoon 5.4.0.1-130 上启动并运行了一项相当大的工作，但不幸的是，当我尝试在 Pentaho Kitchen 上执行相同的工作时，我不断收到错误：

我不知道会发生什么，因此我们将不胜感激。

感谢您的宝贵时间！

【问题讨论】：

看起来厨房没有获得数据库连接。这是共享数据库连接吗？如果是这样，您是从任务调度程序还是从命令行执行厨房？共享数据库连接保存在用户配置文件中，因此您必须使用与勺子中相同的用户执行厨房作业。或者确保两个用户帐户都有可用的数据库连接信息。

【解决方案1】：

谢天谢地，Dirk Trilsbeek 是对的！（参见问题的第一条评论）

问题在于共享数据库连接。一旦我将 schtasks（windows 任务调度程序）配置为使用正确的用户，我就可以毫无问题地使用 Kitchen 来执行我的工作。

以下是我当前用于运行任务的配置：

REM call-pentaho-job.bat
c:
cd /d "C:\pentaho\data-integration"
call Kitchen.bat /file:"C:\app\my-job.kjb" /level:Detailed /logfile:"C:\app\logs\my-job.txt"
exit
REM
REM schtasks /create /tn "MY-PENTAHO-JOB" /tr "\"C:\app\call-pentaho-job.bat\"" /ru MYDOMAIN\myuser /sc daily /st 03:00
REM

谢谢你，德克！

【讨论】：

仅供参考，共享数据库来自用户 .kettle 主目录。您可以为 .kettle 指定一个不同的目录，然后不管它以什么用户身份运行。
