How to Resume a Failed Workflow in Informatica

I am pleased to write this article, as today I have figured out a very important feature of Informatica. I was in a Informatica user group meeting about a month ago. We discussed there that the other organizations are using a third party scheduling tool to schedule workflows of Informatica. I asked them why they do so and they replied that if something fails in the middle of the workflow, there is no way to resume the workflow from the point they want it. They need to run the whole workflow again. Well, that's not true. There is a way to resume the execution of a workflow. 

Here is what we need to do in order to resume a workflow execution. 

• Open the workflow in workflow manager. 
• Right click on the task you want to resume execution from.
• Click on the 'Start Workflow from Task' option.

That's it. 

This will run all the tasks after it, that means all the way down. Note that if there is anything which do not have dependency on it or not in the downstream, will not be executed.
