Managing multiple external context file within talend job

RA6 — Wed, 07 Oct 2020 05:52:39 GMT

Hello guys,

i have a single job, but i have 3 different context file with same keys but different values and i have replicated them for different environment.

/Documents/Contexts/Local Machine/

clientContextFile1.ctx

clientContextFile2.ctx

clientContextFile3.ctx

/Contexts/Preproduction/

clientContextFile1.ctx

clientContextFile2.ctx

clientContextFile3.ctx

/Contexts/Production/

clientContextFile1.ctx

clientContextFile2.ctx

clientContextFile3.ctx

Is there a way to tell the job that which context file needs to runs?

Many thanks.

Best regards,

Duke

Hey,

The answer depends how do you use those files: implicit context load or tContextLoad?

If you use the component:

I would use the internal variable contextStr which refers to the environment where you run your job. Which means you can write an IF clause in the beginning of your prejob. And when calling your job, you can also overwrite context variables: this is important! You need to know the hierarchy of loading context variables: implicit context load >> context in TAC/BAT file >> context in parent job (depending on development >> context in child job)

As you notice, a lot of IFs to answer your question, but I hope it will give you some insights to solve the problem.

Kind regards,
