Kettle——shell交互命令

Kettle——shell交互命令

在kettle上开发了job或transform可以以单独的文件存在，也可以存放在资源库中。调用这些程序可以通过shell脚本调用，记录下：

资源库中的job：

./kitchen.sh -rep ZYFS_REP -user admin -pass admin -param:file_name=/home/etluser/etl_data/test/etl_test.csv -dir /test -job JB_ETL_TEST

单个文件的job：

./kitchen.sh  -file /home/rdb/JB_QFPD.kjb

单个文件的transform:

./pan.sh  -file /home/rdb//TR_QFPD.ktr

数据库资源库和文件资源库的比较：

使用数据库来管理，更容易跨平台和共享，但是在版本控制方面不如文件资源库好，并且数据库需要走网络，网络连接的异常也会导致job失败

使用文件资源库比较麻烦的是跨平台，一般和svn等版本控制的工具结合使用。
