When trying to run invoke process utility for Javelin, it works fine for automating a masking script for a text file, however it does not do anything when used to automate the flow for a DB and the command prompt just hangs for a while and says masking complete.
Release : 4.9.1
Component : Javelin
Found that the step was malformed.
With reference to below article titled "Running a FastDataMasker batch job from the TDM Portal using Javelin."
Steps to prepare the Workflow for use by others.
1) On the server create a Javelin workflow file (.vwf) that executes an FDM batch job for example.
You could use a 'InvokeProcessActivity' step with:
Arguments: "/c c:\mask\mask1.bat"
2) In Javelin, verify that this job runs without error.
Modified the InvokeProcessActivity step with the above guidelines and it worked!
