Setting the context file location in the operating system

The initial context load method and the tContextLoad methods do suffer from having to use a predetermined file location. This exercise shows how it is possible to overcome this via the use of system variables.

Note that this exercise is demonstrated on Microsoft Windows 7; however, it is possible to set and use global environment variables in Talend in any version of Windows, Linux, or Mac OS.

Getting ready

How to do it...

The steps for setting the context file location in the operating system are as follows:

  1. Run the job, and you will notice that the value of the context variable is set to In the job.

  2. Go to Start | Control Panel | System and Security.

  3. Select System, then click the right-hand side Advanced system settings.

  4. Click on the Environment Variables button.

  5. Under the System variables, click on New.

  6. Enter Variable name as TALEND_CONTEXT_DIRECTORY...

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar?
