A colleague has exported a Data Integration Job to run outside Talend Studio.
How do you run the Job?
To run a job that has been exported by a colleague to run outside Talend Studio, you need to extract the content of the archive and run the batch file or the shell script. The archive file contains all the files and libraries required to run the job independently from Talend Studio on any platform that supports Java. 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.
You do not need to extract the contents of the archive and run both the batch file and shell script, install the job and start the resulting service, or extract the files from the archive and run the JAR file. These methods are not correct or available in Talend Studio and may cause errors or unexpected results.

You cannot use a tRunJob component and select Joblet from drop-down menu, nor right-click Joblet from Palette and select Add option. These methods are not available in Talend Studio and may cause errors or unexpected results. References: Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [Joblets - 7.3]
Which factors can affect the context in which a Job is run?
Choose 2 answers
The context in which a job is run can be affected by different factors, such as the context chosen by the developer when running the job, or the tRunJob component that can influence the context in which the child job runs. The context chosen by the developer when running the job can be selected from the Basic Run tab of Run Job section in Talend Studio. This allows the developer to test the job with different sets of context variables without modifying the job design. The tRunJob component can be used to call another job as a subjob within a parent job. The tRunJob component can pass the context parameters from the parent job to the child job, or use a specific context for the child job. This allows the developer to reuse existing jobs and control their execution contexts. The tContextLoad component and the tContextDump component do not affect the context name in which a job is run, but they can affect the context values. The tContextLoad component can load context parameters from a file or a database table at runtime and overwrite the existing values. The tContextDump component can display or save the current context parameters and their values for debugging purposes.
