You designing a Job that can run in two contexts, Test and Production. You want to run it as a standalone job outside Talend Studio.
How do you accomplish this?
A.
Build the Job with the Context scripts option selected in the Build Job windows. Before running the Job, edit the script according to the context in which want to run the job.
B.
Set the desired context as the default, then build the Job. Rebuild the Job if you need to run it in a different context.
C.
Build the Job with the Context scripts option selected in the Build Job windows. You will be prompted for the context.
D.
Build the Job with the desired context selected in the Build Job windows. Build a separate copy if you need to run the Job in a different context.
To design a job that can run in two contexts, Test and Production, and run it as a standalone job outside Talend Studio, you need to do the following steps:
Define the context variables and values for each context in the Contexts tab of your job. A context variable is a variable that can store a value that can be changed at runtime or between different contexts. You can use context variables to parameterize the properties or expressions of your job components.
Build the job with the desired context selected in the Build Job window. You can access this option by right-clicking on your job in the Repository tree view and selecting Build Job. This will open a dialog box where you can configure the build settings, such as destination folder, archive name, context, etc. You need to select the context that you want to use for your job execution from the drop-down menu.
Extract the content of the archive file that contains your job executable files and libraries. The archive file also contains two executable files: a batch file (.bat) for Windows platforms and a shell script (.sh) for Linux platforms. You need to run the appropriate file for your platform by double-clicking on it or using a command line tool. This will launch the job and display its output in a console window.
If you need to run the job in a different context, you need to build a separate copy of the job with the other context selected in the Build Job window. You cannot change the context of an already built job without rebuilding it.
You do not need to build the job with the Context scripts option selected in the Build Job window, edit the script according to the context in which you want to run the job, set the desired context as the default, rebuild the job if you need to run it in a different context, or be prompted for the context. These methods are not correct or available in Talend Studio and may cause errors or unexpected results.
