I have created around 50 jobs with context environments as Default and dev. But now within the context groups , I had to add the environment - prod and test values, which are different. How can I add these context environments to all 50 jobs at a time without using Implicit load as I am not using file or database for storing contexts, as I don't want to open all the 50 jobs and add manually all the context environments again
I cannot advise you strongly enough NOT to use different contexts. I am currently writing a blog post about this. I will post it very soon. Essentially multiple contexts just lead to confusion, more work, more recompilation and just a mess..... even if handled in a "best practice" manner.
The best way to go is via the implicit context load. It gives you complete control WITHOUT having to run the risk of recompiling with value changes, and allows you to forget about which context you are running against if you tie your context to your environment using OS environment variables.
I wasn't going to spend too much covering the ESB context variables. This is mainly because I do not use context variables in Talend Routes. However, I do share my context variable names and values with Talend Routes. I use Property Placeholders and followed this tutorial by @eost (http://edwardost.github.io/cloud/platform/soa/2015/05/14/Working-with-Property-Placeholders-in-Talen...) to get my head around them. Take a look, it's pretty useful.
