通过Kitchen和Pan以命令行方式执行kettle的Job和Transformation

Posted on Posted in kettle基础概念

简述逻辑:
在windows界面打开kettle 进行脚本编写 ,编写好后把kettle的安装压缩包上传到linux服务器 解压 ,在目录下通过Kitchen.sh执行作业,Pan执行转换

1. 准备工作
一个简单的job,一个简单的trans。

本处为了方便和效果易见,job和trans都生成文件。

trans:读取download目录下的所有文件名,输出为文件。【界面情况下测试成功】

 linux环境以命令行方式执行job和trans

  1.  Pan是用于执行trans的PDI命令行工具。
  2.  Kitchen是用于执行作业的PDI命令行工具。

a. Pan的命令行选项和语法
语法:

        pan.sh -option=value arg1 arg2

命令行参数:

Switch Purpose
rep Enterprise or database repository name, if you are using one
user Repository username
pass Repository password
trans The name of the transformation (as it appears in the repository) to launch
dir The repository directory that contains the transformation, including the leading slash
file If you are calling a local KTR file, this is the filename, including the path if it is not in the local directory
level The logging level (Basic, Detailed, Debug, Rowlevel, Error, Nothing)
logfile A local filename to write log output to
listdir Lists the directories in the specified repository
listtrans Lists the transformations in the specified repository directory
listrep Lists the available repositories
exprep Exports all repository objects to one XML file
norep Prevents Pan from logging into a repository. If you have set the KETTLE_REPOSITORY, KETTLE_USER, and KETTLE_PASSWORD environment variables, then this option will enable you to prevent Pan from logging into the specified repository, assuming you would like to execute a local KTR file instead.
safemode Runs in safe mode, which enables extra checking
version Shows the version, revision, and build date
param Set a named parameter in a name=value format. For example: -param:FOO=bar
listparam List information about the defined named parameters in the specified transformation.
maxloglines The maximum number of log lines that are kept internally by PDI. Set to 0 to keep all rows (default)
maxlogtimeout The maximum age (in minutes) of a log line while being kept internally by PDI. Set to 0 to keep all rows indefinitely (default)

示例:

  1. sh pan.sh -rep=initech_pdi_repo -user=pgibbons -pass=lumburghsux -trans=TPS_reports_2011
  • 1

本地trans调用示例:

./pan.sh -file=/home/hadoop/workplace/kettle/trans/test_cml.ktr -norep
  • 1

b.Kitchen的命令行参数及语法:

语法与Pan一样,参数有点不同。

Switch urpose
rep Enterprise or database repository name, if you are using one
user Repository username
pass Repository password
job The name of the job (as it appears in the repository) to launch
dir The repository directory that contains the job, including the leading slash
file If you are calling a local KJB file, this is the filename, including the path if it is not in the local directory
level The logging level (Basic, Detailed, Debug, Rowlevel, Error, Nothing)
logfile A local filename to write log output to
listdir Lists the sub-directories within the specified repository directory
listjob Lists the jobs in the specified repository directory
listrep Lists the available repositories
export Exports all linked resources of the specified job. The argument is the name of a ZIP file.
norep Prevents Kitchen from logging into a repository. If you have set the KETTLE_REPOSITORY, KETTLE_USER, and KETTLE_PASSWORD environment variables, then this option will enable you to prevent Kitchen from logging into the specified repository, assuming you would like to execute a local KTR file instead.
version Shows the version, revision, and build date
param Set a named parameter in a name=value format. For example: -param:FOO=bar
listparam List information about the defined named parameters in the specified job.
maxloglines The maximum number of log lines that are kept internally by PDI. Set to 0 to keep all rows (default)
maxlogtimeout The maximum age (in minutes) of a log line while being kept internally by PDI. Set to 0 to keep all rows indefinitely (default)

执行本地job的命令行语句:

    /home/kettle/data-integration/kitchen.sh -file=/home/kettle/transition/move.kjb -log=log.log
  • 1

形式:

    $kitchen路径 -file=$job路径 log=$log路径

3.个人常用命令选项

由于我当前的工作环境都是执行本地的job和trans文件,所以常用的命令选项有:

命令 描述
-file job或trans文件路径
-norep 标明不是资源库里的文件
-param 参数设置
-logfile log输出文件名
-level log级别 (Basic, Detailed, Debug, Rowlevel, Error, Nothing)
