When you deploy an application that includes ATG Commerce, the pipeline manager is automatically reinitialized. If you make changes to a pipeline definition and you want the changes to take affect in the session you are currently running, you must reinitialize the pipeline manager.
Follow these steps to reinitialize the pipeline manager.
Open an existing pipeline definition
Modify the definition. For example, delete a link in a chain or change a link to execute a different processor.
Click on Save your changes.
Click on the Reinitialize button to load the new definition into the pipeline manager.
