Datatage中Parameter Set的使用

我就是我 2022-01-15 03:47 264阅读 0赞

1.新建Parameter Set，File-->New视图下，选择Other-->Parameter Set,点击OK

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70][]

在General标签下输入参数集名称，参数集名称应该简短

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 1][]

在Parameter中定义参数，参数名称需要具有可描述性

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 2][]

2.新建测试作业，在Job Properties中，通过Add Parameter Set引入之前添加的参数集

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 3][]

测试作业如下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 4][]

在Transformer中引入参数，作为输出测试用

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 5][]

3.运行测试作业

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 6][]

查看运行结果，输出456

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 7][]

4.修改作业集的参数NAME的值为123

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 8][]

5.重新运行作业，此时发现NAME的值还是456

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 9][]

运行结果也还是456，修改作业集中的参数，未对作业生效

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 10][]

6.修改作业集参数，将参数保存到参数集文件中（参数集可以保存到多个文件中，每个文件中的参数值可以不同，用于区分不同的场景）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 11][]

此时参数集会保存到服务器$PROJECTHOME/ParameterSets/*ParameterSetName*/*ValueFileName文件中*

7.运行测试作业，此时会发现测试集参数的value中会出现一个下拉框，可以选择参数集文件名

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 12][]

选择参数集文件后，会发现参数NAME的值也随之修改为777

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 13][]

查看运行结果，运行结果显示777

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 14][]

8.修改参数集文件中的参数值，重新运行作业

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 15][]

运行结果随之改变

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2JmaGFp_size_16_color_FFFFFF_t_70 16][]

9.使用dsjob命令运行带参数集的作

查看作业参数

dsjob -lparams dstage1 TEST_PARA

![20190613111651705.png][]

运行作业

dsjob -run -mode NORMAL -param MY_PA=MYPA_FILE  -wait dstage1 TEST_PARA

![2019061311172562.png][]
