Process Description Files
The Integration Server package that Designer generates on each server also contains a process description file for that server. These files have a file name extension of .frag, and are sometimes referred to as frag files. The process description file for each server contains the following:
*Process model version property settings.
*For each step that will run on the server, the step definition and the step ID for the next step to run.
*If the process model version uses an express pipeline to pass data from step to step, a list of all inputs explicitly specified for downstream steps in the model version.
*If the process model version uses correlation IDs, the correlation service name and properties.
You should have no need to edit a process description file.
